Boiled feed is obtained by mixing and boiling agricultural by-products such as rice straw, rice bran, and bean curd with grains. The study explored the change in fatty acid, free amino acid, nucleotide, mineral, cholesterol, myoglobin and collagen of longissimus dorsi muscle in Hanwoo steers fed with boiled feed. Forty steers, 20 heads per group, were divided into two groups: a control group and a boiled feed group. The steers were raised for 10 months. The boiled feed group was enriched with palmitoleic acid, oleic acid, arachidonic acid and unsaturated fatty acids compared with the control group. There were no significant differences in amino acid and nucleic acid composition between the two groups. The boiled feed group contained higher levels of iron and manganese in the boiled feed group compared with the control group. The total cholesterol level was significantly increased, whereas calorie levels, myoglobin and collagen composition showed no differences. As the supply of boiled feed increases the content of fatty acids, unsaturated fatty acids and minerals related to flavor, it should be a feed that leads to the production of high-quality beef.

Objective: To determine the effect of three salting treatments (control, 100% NaCl; T1, 60% NaCl and 40% KCl; T2, 50% NaCl, 40% KCl, and 10% MgCl2) on meat quality of sausages during storage.Methods: Various types of curing salts were used for processing of salamis. Physico-chemical and sensory evaluation of the sausages were analyzed during 4 weeks of ripening.Results: The pH values and salinity contents were the highest in control, while they were the lowest in T2 at 4 weeks (p

Synthetic nitrite imparts a reddish-pink color to meat and a distinct flavor to meat products, delays lipid oxidation, and inhibits microbial growth and pathogens. However, excessive intake of nitrite might result in the production of carcinogenic nitrosamine, which might increase the risk of cancer in humans. Therefore, we aimed to find an alternative natural colorant for pork sausages. Pork sausages were mixed with 0.014% sodium nitrite (NaNO2) alone (CON), without either NaNO2 or purple-fleshed sweet potato powder (PP; CON1), 0.5% PP alone (PP1), 1% PP (PP2) alone, 0.011% NaNO2 and 0.5% PP (SP1), and 0.011% NaNO2 and 1% PP (SP2). The sausages were then cooked and stored for physicochemical analysis on days 0, 5, 10, 15, and 20. The a* and W* values were the greatest and lowest in the SP2 and CON1 treatments, respectively (p < 0.05). The concentrations of residual nitrite in the sausages at 20 days decreased in the order of CON > SP1, SP2 > PP2 > PP1, CON1. The fatty acid content was higher, and flavorous amino acids were more in PP2 (p < 0.05). The fatty acid composition was comparable between the SP2 and CON groups, but the contents of glutamic acid and alanine were greater in the SP2 group. In conclusion, SP2 (0.011% NaNO2 with 1% PP) could be added as a natural colorant for pork sausage production, and NaNO2 could be substituted with up to 20% PP without detrimental effects on sausage appearance and/or quality.

The aim of this study was to assess the impacts of cellulose/chitosan addition in combination with sodium substitution, including KCl and MgCl2, on the quality and sensory properties of sausages. Sausages (control, 100% NaCl; T1, 60% NaCl, and 40% KCl; T2, 50% NaCl, 40% KCl, and 10% MgCl2) were formulated with cellulose/chitosan at concentrations of 3% and compared to control. T1 and T2 decreased the pH values (p

In this study, we assessed the antioxidative ability of 23 natural sources in a meat model system at the same addition level (1.0%). We evaluated the free radical (2,2-diphenyl-1-picrylhydrazyl, DPPH) scavenging ability of natural plant sources and their peroxides, as well as their aldehyde-inhibiting ability in pork patties, over 10 days of cold storage. It was found that blueberries, cherries, onions, black tea, and clove buds (20.6–25.0 mg AA/g) have a higher DPPH scavenging ability than that of other natural sources (10.80–16.7 mg AA/g) ( P < 0.05 ). Moreover, it was found that peroxides in pork patties are largely inhibited by red wine, lettuce, and red ginseng ( P < 0.05 ), whereas aldehydes are significantly inhibited by blueberries, chokeberries (aronia), blackcurrant, clove buds, elderberries, ginger, and cinnamon ( P < 0.05 ). These inconsistencies detected in the antioxidative ability of these 23 natural sources indicate that it is important to perform comprehensive and practical assessments of the potential antioxidative ability of natural sources. In addition, it is assumed that the interactions between natural plant sources and meat components affect the inhibition of lipid oxidation in meat and meat products.

Charcoal-grilling is a popular cooking method but causes the formation of polycyclic aromatic hydrocarbons (PAHs), which can be harmful to human health. Gochujang marinade is commonly used for flavoring meats during charcoal-grilling. However, the effects of this marinade on PAHs formation during charcoal-grilling are unclear. Here, we evaluated the effects of Gochujang marinade on the formation of 16 PAHs and inhibition rate of major PAHs (benzo[a]anthracene, benzo[b]fluoranthene, and benzo[a]pyrene) in charcoal-grilled pork belly. Pork belly without marinade (PBW) and marinated with Gochujang (PBG) were stored for 10 days at 9°C under vacuum conditions and then charcoal-grilled to different doneness (internal temperatures of 71°C and 81°C). Among 16 PAHs evaluated in this study, 14 PAHs were detected in charcoal-grilled pork belly, regardless of doneness. PAH formation in charcoal-grilled pork belly was higher at an internal temperature of 81°C than at 71°C (p

This study investigated the effects of different curing agents on the physicochemical properties, microbiological properties and sensory evaluation of sausages formulated with and without nitrite over 4 weeks of cold storage. Seven batches were prepared: control, sodium nitrite 0.01%; celery powder 0.8% (T1); fruit extract powder 0.6% (T2); purple sweet potato powder 0.45% (T3); fruit and vegetable extract powders 0.5% (T4); gardenia red 0.04% (T5); paprika and blueberry powder 0.07% (T6). T1 produced significantly lighter, redder and yellower sausages compared to control and had a higher color intensity (C*) and hue (h). The residual nitrite ion concentration was the highest in the control and declined most rapidly in control, T1, and T2 during storage. The pH, thiobarbituric acid reactive substances (TBARS), volatile basic nitrogen (VBN) content, and total microbe counts were the same for T1 and the control. T1 received comparable sensory attributes as the control. These results suggest that celery powder effectively protects sausages from quality deterioration during storage.

This study was performed to investigate the effect of Gleditsia sinensis Lam. extract on the physicochemical properties of emulsion-type pork sausages during storage at 10°C for 4 wk. Treatments were as follows: (C, control; T1, sodium ascorbate 0.05%; T2, Gleditsia sinensis Lam. 0.05%; T3, Gleditsia sinensis Lam. 0.1%; T4, Gleditsia sinensis Lam. 0.2%; T5, Gleditsia sinensis Lam. 0.1% + sodium ascorbate 0.05%). The values of pH, moisture content, lightness, redness, and sensory attributes were all significantly decreased, while the yellowness, chroma, hue angle, and texture properties were increased during storage with increase of the Gleditsia sinensis Lam. extract added. In addition, the antioxidant activity and antimicrobial activity in the sausages displayed significant increases (p

In the present study, we determined the degree of hydrolysis (DH) of porcine blood plasma proteins, albumin, and globulin hydrolyzed by six proteases (alcalase, neutrase, flavourzyme, protamex, trypsin, and papain) for various reaction times. Moreover, antimicrobial activities of hydrolysates against five pathogenic microorganisms (Bacillus cereus, Staphylococcus aureus, Salmonella Typhimurium, Escherichia coli, and Shigella flexneri) were investigated. Alcalase, trypsin, and papain hydrolysates of the three porcine blood proteins showed higher DH values than hydrolysates produced by the other three proteases. DH of the three porcine blood proteins hydrolyzed by the six proteases failed to increase after 2 h of hydrolysis. In antimicrobial tests, hydrolysates (hydrolysis time of 2 h) showed antibacterial activity only against B. cereus. Albumin hydrolysates showed higher antimicrobial activity than globulin and plasma hydrolysates. Albumin hydrolysates obtained with flavourzyme, protamex, and trypsin showed higher antimicrobial activity than those obtained with the other three proteases.

The purpose of this study was to evaluate the antioxidative activities of Crab meat analogue prepared with protein hydrolysates obtained from mechanically deboned chicken meat (MDCM) from spent laying hens. 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) radical-scavenging activity was increased by adding MDCM hydrolysates during storage, and activity correlated with the concentration of DPPH added up to 6 weeks of storage. Hydroxyl radical-scavenging activity was increased in all analogues containing MDCM hydrolysates. At 0 days of storage, angiotensin I-converting enzyme (ACE)-inhibitory activity was increased by the addition of MDCM hydrolysates. Activity did not correlate after 6 weeks of storage, in which ACE-inhibitory activity was increased with low concentrations of MDCM hydrolysates, but no ACE-inhibitory activity was observed at higher concentrations. The liver-protecting activity of crab meat analogue was shown to be around 60% of the positive control; however, it was not significantly different among the samples during storage. These results support the use of MDCM as a source of health-promoting constituents in crab meat analogue.

BACKGROUND Clove bud is a widely used spice in meat and meat products, and it contains high level of phenolic compounds. The effectiveness of the clove as a spice has not been fully studied at a general level of addition in the meat products. Therefore, in the present study, the antioxidant, antimicrobial, and nitrite scavenging abilities of clove bud powder (CBP) was assessed at spice level (0.1% and 0.2%) in emulsified pork sausage, during 6 weeks of cold storage. RESULTS CBP had DPPH radical scavenging ability, but CBP addition at 0.1% and 0.2% did not decrease the TBARS value. An antimicrobial effect of CBP was also not observed during the cold storage. However, residual nitrite at storage weeks 4 and 6 was shown to be lower (P 0.05). CONCLUSIONS The positive effect on nitrite scavenging could be expected by the addition of 0.2% CBP as a spice. However, antioxidant and antimicrobial abilities were not observed, as well as improvement in the quality of characteristics, in emulsified pork sausage. © 2016 Society of Chemical Industry

This study was conducted to evaluate the substitution effect of red beet powder on sodium nitrite in emulsion-type pork sausages, and to investigate the effect of the addition of red beet powder on the physicochemical characteristics of emulsion-type pork sausages at 10° C for 6 weeks. The treatments were divided into five groups: Control (sodium nitrite 0.01%), T1 (sodium nitrite 0.005% + red beet powder 0.5%), T2 (sodium nitrite 0.005% + red beet powder 0.25%), T3 (red beet powder 0.5%), and T4 (red beet powder 0.25%). In the CIE* I didn't delete this asterisk (*) because it might be a marker for something you wish to add later, but please note that if there is no significance for the asterisk, it should be removed as a typographical error. color of emulsion-type pork sausages, the lightness value of the control was significantly higher than for the other groups (p

The purpose of this study was to evaluate the functional properties of herbal medicine aqueous extracts as natural preservatives to improve the quality characteristics and oxidative stability of emulsion-type pork sausage. The pH value was significantly higher in sausages of control than in groups containing herbal medicine extracts (p

The effects of Coptis chinensis Franch (CCF) powder extract and potassium sorbate addition on the quality characteristics of sausages during cold storage were investigated. Sausages were prepared with potassium sorbate (0.2 %) and CCF extracts (0.2 and 0.4 %) and stored for 4 weeks. Compared to the control, lipid oxidation values dose-dependently decreased in sausages containing CCF before and after 4 weeks of storage. The addition of CCF increased the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) radical scavenging activity of sausages. Hardness, cohesiveness, and springiness of sausage samples did not show any consistent trends. The chewiness decreased in the control and in sausages containing CCF at 4 weeks of storage, whereas the adhesiveness increased after 4 weeks in sausages containing potassium sorbate and 0.2 % CCF. The lightness, redness, and whiteness dose-dependently decreased in sausages containing potassium sorbate and CCF, whereas yellowness dose-dependently increased before and after 4 weeks of storage. During storage, compared to the control, the total plate count and lactic acid bacteria diminished in sausages with potassium sorbate and CCF. In sensory evaluation, the overall acceptability of sausages was significantly influenced by CCF addition and was lower than that of the control sausages and sausages containing potassium sorbate alone.

The effects of biopolymer encapsulation and sodium replacement combination technology on quality characteristics (i.e., bitter taste) and inhibition of sodium absorption from pork sausage in mice were evaluated. The sausages were divided into three different sodium replacement groups (none, 40%, and 50%) and three different biopolymer encapsulation groups (none, cellulose, and chitosan) in combination. In groups with 50% sodium replacement by KCl and MgCl2, T8 (chitosan encapsulation) showed the highest inhibition of the sodium absorption rate. However, chitosan encapsulation groups (T2, T5, and T8) had higher bitterness and lower overall acceptability than other treatment groups. In contrast, in the group with 40% sodium replacement by KCl, T4 (cellulose encapsulation) exhibited the highest inhibition of sodium absorption without a bitter taste. This is the first report showing that 40-50% sodium replacement combined with 3% cellulose encapsulation reduced sodium absorption from sausage by 60% without causing a bitter taste.

The purpose of this study was to assess red beet as a natural colorant in emulsified pork sausage and to investigate the effect of red beet on quality characteristics of emulsified pork sausage during 20 d of cold storage. Red beet was prepared as a powder and a substitute with sodium nitrite at 0.5% and 1.0% levels in emulsified pork sausage. Red beet significantly increased the moisture content and pH (p0.05). Texture and 2-thiobabituric acid reactive substance were also not affected by red beet addition (p>0.05). Therefore, red beet could be a good natural colorant in emulsified pork sausage but it needs additional processing, such as betalain concentration and extraction as a juice, to be used as an antioxidant in meat products.

The effects of C. sappan L. extract on oxidative stability, microbiological quality, and color attributes in sausages were examined. Pork sausages were prepared for four treated groups: control (without antioxidant), T1 (added with 0.007% sodium nitrite), T2 (added with 0.1% C. sappan L.), and T3 (added with 0.0035% sodium nitrite+0.1% C. sappan L.). T3 showed lower L. monocytogenes count than that saw in the control and T2 (p

The individual and interactive effects of Schisandra chinensis powder (SCP) and sodium nitrite additions on color, pH, water holding capacity, residual nitrite, 2-thiobarbituric acid reactive substances (TBARS), volatile basic nitrogen, texture properties, fatty acids, amino acids and sensory evaluation of cooked pork sausages were investigated after 20 d of storage at 4C. The powders (0, 0.5 and 1.0%) were added to sausages either alone or in combination with nitrite (0 and 100 ppm). SCP added-sausages showed lower L* (lightness) and W (whiteness) values, and higher b* (yellowness) values than sausage containing no nitrite, and exhibited the highest a * values at a 0.5% addition (p

Many studies have been carried out with respect to packaging methods and temperature conditions of beef. However, the effects of packaging methods and temperature conditions on the quality characteristics have not been extensively studied in low-grade beef. Low-grade beef samples were divided into 3 groups (C: ziplock bag packaging, T1: vacuum packaging, and T2: modified atmosphere packaging (MAP), CO2/N-2 = 3:7) and samples were stored at 4 degrees C for 21 days. The water-holding capacity (WHC) was significantly lower in T1 than in the other samples up to 14 days of storage. The thiobarbituric acid reactive substances and volatile basic nitrogen values were significantly lower in T1 and T2 than in C after 7 to 14 days of storage. The total bacterial counts were significantly lower in T1 and T2 than in C after 14 days of storage. In a sensory evaluation, tenderness and overall acceptability were significantly higher in T1 and T2 than in C at the end of the storage period (21 days). We propose that the MAP method can improve beef quality characteristics of low-grade beef during cold storage. However, the beneficial effects did not outweigh the cost increase to implement MAP.

This study was carried out to determine the effects of tomato powder (TP) on cooked pork patties during storage at 10 1 C in the dark. The total phenolic and flavonoid contents of TP extract were 26.22 mg gallic acid/100 g and 3.52 mg quercetin/100 g, respectively. The extract of TP showed a potential antioxidant activity in the DPPH radical-scavenging assay (EC50 = 16.76 mu g/mL). Pork patties were manufactured with 0.25% (T1), 0.5% (T2), 0.75% (T3) and 1.0% (T4) TP in a basic formula (C). The pH and volatile basic nitrogen (VBN) values of T2, T3 and T4 patties were lower (p

The present study investigated the effects of Liriopeplatyphylla extract (LPE) and Akebiaquinata extract (AQE) on breastmeat properties when used as dietary supplements of broiler chickens. First, the identification and quantification of phenolicacids and flavonoids were carried out by HPLC. As a result, the total amount of phenolic acids and flavonoids was higherin AQE than LPE. These extracts were added at a rate of 0.2% to the broiler diets, and a feeding trial was conducted inbattery cages for 35 d. At the end of the experiment (d 35), six carcasses from each treatments were used for evaluating meatquality. The experimental results indicate that color shades, pH levels, volatile basic nitrogen, thiobarbituric acid reactivesubstance (TBARS), cooking loss and drip loss of breast meat fed with 2 extracts were not different as compared with thecontrols at d 0 and d 10 of storage. However, TBARS values of breast meat fed with either the control diet or the LPE sup-plementation was increased as the storage period increased (from d 0 to d 10) (p

Fried fish paste (FFP) samples were divided into four treatments: a control composed of commercial FFP containing no breast meat batter from spent laying hens, and treatments 1, 2, and 3, in which Itoyori surimi was substituted with 7.46, 14.93, and 22.39 % batter from the breast meat of whole spent laying hens, respectively. Moisture content was significantly lower in T3 than in the FFP samples, whereas crude fat was significantly higher in T3. Polyunsaturated fatty acid contents were significantly higher in the control than the other FFP samples, whereas saturated fatty acid contents were significantly higher in T3. The breaking force, deformation, gel strength, and jelly strength values were higher in the control than the other FFP samples during storage. Thiobarbituric acid reactive substances (TBARS), as a measure of lipid oxidation, and volatile basic nitrogen, as a measure of protein degradation, were significantly higher in T3 than in the other samples. Additionally, the control had a significantly lower TBARS level than the other samples. In sensory evaluation, color, aroma, flavor, and juiciness were not significantly different among FFP samples during storage. The results show that physicochemical properties such as gel characteristics, shear force, and fatty acid composition are influenced by substitution with spent laying hen meat batter. However, sensory evaluation scores are less influenced by this substitution.

The effects of thyme and rosemary on the quality characteristics of sausages during cold storage were investigated. Sausages were prepared with thyme and rosemary powder (1 and 2%) and stored for 6 weeks at 10℃. The pH was significantly decreased in sausages by addition of thyme and rosemary compared to that observed in the control before and after storage. At 4 weeks of storage, the residual nitrite content was decreased by thyme and rosemary compared to the control. Lightness (L*) and yellowness (b*) were increased during storage, whereas redness (a*) and whiteness (W) were decreased before and after storage by addition of thyme and rosemary. The amount of TPC and lactic acid bacteria was lower at the end of storage in sausage containing thyme and rosemary. The 2, 2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) radical scavenging capacity of sausages was increased by addition of thyme and rosemary compared to that in the control before and after storage. In particular, T2 (0.2% thyme addition) showed the highest DPPH radical scavenging capacity during storage. In a sensory evaluation, flavor and overall acceptability were lower in sausages containing thyme and rosemary than in the control. However, at the end of storage (6 wk), aroma, flavor and overall acceptability were not significantly different among the sausage samples.

본 연구는 glucomannan, carrageenan, carboxymethyl cellulose 및 transglutaminase-B의 0.5% 첨가가 돈육껍질 돈육껍질결체조직 함유 돈육 패티의 품질특성에 미치는 영향에 대해 알아보고자 실시하였다. 육색의 경우, 대조구와 처리구들간 유의적인 차이가 나타나지 않았다. 관능평가 또한 모든 처리구들간 유의적인 차이가 나타나지 않았다(P>0.05). 그러나 가열감량의 경우, 저장말기인 21일에 대조구에 비해 모든 처리구들에서 낮은 가열감량 값을 나타내며, 전단가 또한 저장 14일에 CMC 및 TGB 처리구들에서, 저장 21일차엔 GMN 및 TGB 처리구에서 대조구에 비해 낮은 전단가 값을 나타내었다(P

This study was carried out to investigate the effects of substitution of fermented king oyster mushroom (P. eryngii) by-products diet on pork meat quality characteristics, during the storage. A mixture of 40% king oyster mushroom by-products, 28% soybean meal and 20% corn was fermented for 10 d, and the basal diet was then substituted by the fermented diet mixture of up to 20, 50 and 80%, respectively. A total of 96 pigs were fed experimental diet (8 pigs per pen× 4 diets × 3 replication), and eight longissiumus (LD) per treatment were collected, when each swine reached to 110 kg of body weight. The Warner-Bratzler shear forces and cooking loss were significantly lowered in the treatments, while crude protein content and water holding capacity significantly (p 0.05). The pH, thiobarbituric acid reactive substances (TBARS), VBN and meat color in all treatments were increased as storage increased. Fermented king oyster mushroom by-products diet effects on lightness (CIE L * ), yellowness (CIE b * ) and chroma were determined, when LD muscles in T2 and T3 treatments were higher (p

This study was conducted to evaluate the effects of adding purple-fleshed sweet potato (PFP) powder on the texture properties and sensory characteristics of cooked pork sausage. Sodium nitrite alone and sodium nitrite in combination with PFP were added to five different treatments sausages (CON (control) = 0.01% sodium nitrite, SP25 = 0.005% sodium nitrite and 0.25% purple-fleshed sweet potato powder combination, SP50 = 0.005% sodium nitrite and 0.5% purple-fleshed sweet potato powder combination, PP25 = 0.25% purple-fleshed sweet potato powder, PP50 = 0.5% purple-fleshed sweet potato powder). The sausages were cooked to 74°C, stored at 4°C for 6 wks, and used for chemical analysis, textural properties, and a sensory evaluation on 0, 2, 4 and 6 wks of storage, respectively. Similar CIE a* and b* values were determined in sausages from CON, SP25 and SP50 at the end of storage, and they were higher in CIE a* but lower in CIE b* than that of the PP25 and PP50 sausages. Significant differences were observed for brittleness and hardness when PFP was added to the sausages but were not confirmed after 4 wks of storage. The objective color score was influenced by adding PFP; however, the effect was not dose dependent. In overall acceptability, panelists favored the CON, SP25, SP50, and PP50 sausages but did not prefer PP25 sausages at the end of storage. Therefore, adding PFP to cooked pork sausages improved color and texture properties and sensory characteristics, but further study is needed to determine the proper ratio of sodium nitrite and PFP.

Swine Science and Technology Center, Gyeongnam National University of Technology, Jinju 660-758, KoreaABSTRACT To investigate the effects of Cordyceps ochraceostromat, silkworm cocoon and conjugated linoleic acid (CLA) addition on the quality of cremi during storage, this study was conducted. Cremis were prepared using a 20% spent layer breast recovered protein to replace Alaska pollack with the addition of 0.1% silkworm cocoon powder (T1), 0.05% silkworm cocoon powder+0.05% Cordyceps ochraceostromat powder (T2), and 0.05% silkworm cocoon powder+0.05% CLA. All manufactured cremis were vacuum-packaged, stored at 10±1and finally evaluated for their quality on 0, 2, 4 and 6 weeks of storage. The pH, whiteness, gel strength and breaking force of cremis from T2 were higher than those of samples derived from either T1 or T3. However, cremis from T2 showed low shear force values when compared to other cremis (p

The effect of by-products of oriental medicinal plants (OMP; T1) containing 0.03% herb extracts (T2) or 0.1% aminolevulinic acid (T3) on the production performance of swine during the finishing period and on its meat quality were investigated. No significant differences were found in the weight gain, feed intake and feed conversion rate among the tested groups (P > 0.05). But the treated group showed higher (P < 0.05) moisture and ash and lower protein than the control group. The T3 group showed a lower meat cholesterol content (38.42 mg/100 g) compared to the other groups (P < 0.05). The vitamin E content of the muscle in the treated groups was higher compared to the control group. No antibiotic content was detected in all treated and control samples. The values of the volatile basic nitrogen (VBN) and thiobarbituric acid reactive substance (TBARS) of the treated groups were significantly lower (P < 0.01) than the control group. The treated groups had significantly better (P < 0.05) sensory-test scores for color, flavor, off-flavor and total acceptability compared to the control group.

Surimi-like samples were divided into four groups (C, surimi-like material made from Alaska Pollack with all cryoprotectant ingredients; T1, surimi-like material made from chicken breast with sugar and a sorbitol-free cryoprotectant; T2, surimi-like material made from chicken breast with a sugar-free cryoprotectant; T3, surimi-like material made from chicken breast with all cryoprotectant ingredients). Water and protein content were lower in Alaska Pollack surimi-like material (C) than those in chicken breast surimi-like material. Centrifuge loss and cooking loss were higher in C than those in chicken breast surimi-like material. Lipid oxidation (thiobarbituric acid reactive substances) was lower in T3 than others during storage. In a sensory evaluation, overall acceptability was significantly higher in C than those in other samples during storage. As a result, we found that the raw material composition (Alaska Pollack or chicken breast) had a large influence on the physico-chemical characteristics and quality of surimi-like materials, whereas cryoprotectant composition may have less influence on the physico-chemical characteristics and quality of surimi-like materials.

A total of ninety swine (79.0±2.2 kg) were employed for 58 d to determine the meat quality of pigs fed fermented agricultural by-products (FAB) mainly consisting of brewers grain shell. FAB was replaced with commercial feed at dietary levels of 20%, 40%, 60%, 80%, and 100% (T1) and 30%, 60%, 100%, 100%, and 100% (T2) at 1, 2, 3, 4 and 5-9 wk, respectively. Compared with the control (CON) feed, FAD feed had lower moisture and nitrogen-free extract content, and higher crude fat, crude fiber, and total calorie (p

Imitation crab stick samples were made from Alaska pollack with protein recovered from spent laying hens breast meat (C), Alaska pollack with spent laying hens breast recovered protein and cordyceps powder (T1), Alaska pollack with spent laying hens breast recovered protein and silkworm cocoon powder (T2), and Alaska pollack with spent laying hens breast recovered protein and conjugated lino- leic acid (CLA) (T3). There were no significant differences in moisture, crude protein and crude fat among the imitation crab samples. pH was significantly higher in T2 and T3 compared with C and T1 after 4 weeks of storage. The values of L*, a*, b*, and W (whiteness) in T3 were found to be more stable during storage and W in T3 was significantly higher than other samples. T3 was significantly lower in hardness, brittleness, gumminess and adhesiveness after 4 weeks of storage. Thiobarbituric acid reactive substance (TBA) values decreased with storage, whereas volatile basic nitron (VBN) val- ues increased with storage periods in all samples. In sensory evaluation, there were no significant dif- ferences in color, odor, taste, tenderness, juiciness and overall acceptability among the samples. T3 was significantly lowest in quality among the treated samples.

This study was conducted to investigate the effects of Cordyceps ochraceostromat, silkworm cocoon, and conjugated linoleic acid (CLA) on the quality and storage properties of pork sausage manufactured with protein recovered from breast of spent laying hen during 4 wks of storage at 4 . Pork sausages were prepared using 100% ham (control) and 40% recovered protein from breast of spent laying hen to replace pork (T1), and with added different sources to final concentrations of 0.1% Cordyceps ochraceostromat powder (T2), 0.1% silkworm cocoon powder (T3), 0.1% CLA (T4), 0.05% Cordyceps ochraceostromat + 0.05% silkworm cocoon (T5), 0.05% Cordyceps ochraceostromat + 0.05% CLA (T6), and 0.05% silkworm cocoon + 0.05% CLA (T7). The treatments T5 and T7 had higher (p

This study was carried out to determine the effects of olive oil prepared tomato powder (OPTP) used as lycopene source on fresh pork patties. OPTP was not added (0%; C), or was added at 0.25% (T1), 0.5% (T2), 0.75% (T3) and 1.0% (T4) in a basic pork patty formula and patties were stored for 7 days at 5℃. pH values of T3 and T4 were lower (p＜0.05) than those of control until storage day 3. However, pH values of treated samples were dramatically increased (p＜0.05) after 7 d of storage. Cooking loss values of treatments were lower (p＜0.05) than those of control at day 1 of storage. Thiobarbituric acid reacting substances values were lower (p＜0.05) in all treatments than in untreated samples during storage. All treated samples had lower values (p＜0.05) for lightness (L*) but significantly higher values (p＜0.05) for redness (a*) and yellowness (b*) than the untreated samples during storage. Total plate counts of T4 were lower (p＜0.05) than others during storage. In sensory evaluation, the scores of color, aroma and overall acceptability in T3 and T4 scored higher (p＜0.05) than those of control at days 1 and 3 of storage, however, statistical significance was not found (p＞0.05) among the samples after 7 days of storage. In conclusion, tomato powder-treated groups were significantly higher in redness (a*) and yellowness (b*), and lipid oxidation was inhibited, as compared with control during storage. Therefore, as a natural additive, tomato powder could be used to extend the self-life of meat products, providing the consumer with food containing natural additives, which might be seen more healthful than those of synthetic origin.

This study was conducted to investigate the effects of the addition of cordyceps ochraceostromat, conjugated linoleic acid (CLA) and silkworm cocoon on the quality and storage characteristics of pork sausage manufactured by MDCM (mechanically deboned chicken meat) recovered protein. The samples were divided into 5 groups (sausage made from pork ham; control, 40% of MDCM recovered protein to replace pork ham; T1, 40% of MDCM recovered protein to replace pork ham with 0.1% cordyceps ochraceostromat; T2, 40% of MDCM recovered protein to replace pork ham with 0.1% CLA; T3, and 40% of MDCM recovered protein to replace pork ham with 0.1% silkworm cocoon; T4).

The objective of this study was to evaluate the effect of dietary lycopene supplementation on meat quality in Longissimus Muscle of Korean native pigs. Meat samples were obtained from pigs which had been fed with finishing pig diets containing basal diets (C), 200 ppm lycopene (T1), 400 ppm lycopene (T2), and 800 ppm lycopene (T3). Longissimus muslce pH was not influenced by feeding lycopene. Total microbial counts of treatments were significantly lower than those of control at 0 day of storage (p

The Korean native black pig (KNP) have several desirable meat qualities, which are highly demanded by Koreans in spite of its slow growth rate, low feed efficiency, and small litter size. The aim of this study was to evaluate meat quality and fatty acid composition of KNP at different slaughter weight in order to provide information to industry. Ninety female KNP of the same age (220 days) were divided into three groups by live body weights (30 pigs per each group); live weight of 50～59 ㎏ (T1), 60～69 ㎏ (T2) and 70～80 ㎏ (T3), respectively. After slaughtering the longissimus dorsi muscle (LD) and backfat from each group were obtained after 24 hr chilling. Crude protein content and shear force of LD from T3 was higher than that from T1 and pH of LD was significantly lower in that from T1 than from T2 and T3. Color measurement indicated that LD of T2 group had a higher L*-value and lower a*-value than those of T1 and T3. Slaughter weight of KNP generally did not affect the fatty acid composition of LD and backfat but the content of oleic acid (C18:1) of T2 in LD was significantly higher than those of T1 and T3. The results may provide basic information to industry to promote the production and processing of KNP, and assist in meeting the Korean consumer's demand.

A total of 100 pigs were used to investigate the effects of pig breed on proximate, physicochemical, cholesterol, amino acid, fatty acid and sensory properties of loins.

Four different pork patties were made with two levels, HP/FP-3% and HP/FP-6%, containing 3.0 and 6.0% HP (hot air dried sweet persimmon powder)/FP (freeze-dried sweet persimmon powder), respectively. After manufacture, the meat patties were packaged with polyvinyl wrap and stored at 4 for 8 days. CTL (control) and HP-3% meat patties were significantly (p 0.05) different among the meat patty samples. The value of pH, L* and a* values were decreased as the cold storage time increased in all treatments (p

This study was conducted to determine the effect of pH adjustment and the addition of cryoprotectants on the storage properties of chicken breast surimi. Surimi as a control was prepared with Alaska pollack by two times of washing treatment and addition of cryoprotectants (4% sugar, 5% sorbitol and 0.3% polyphosphate). Three types of surimi were manufactured by different cryoprotectant conditions (T1: 5% sorbitol + 0.3% polyphosphate, T2: 4% sugar + 5% sorbitol + 0.3% polyphosphate, T3: 2% salt + 4% sugar +5% sorbitol + 0.3% polyphosphate) and frozen after adjusting the surimi to pH 11.0. The amino acid and saturated fatty acid composition were significantly higher in the control. EAA (essential amino acid), FAA(amino acid in relation to flavor), SAAA (amino acid in relation to saccarinity) and FRAA (fragrant amino acid) were significantly higher in the control. The TBARS (thiobarbituric acid reactive substances) and VBN (volatile basic nitrogen) were increased with storage times. TBARS and VBN values were significantly higher in the control and T3 than the other treatments. The VBN was significantly higher in control and T3 than other surimi samples. Chicken breast surimi adjusted to pH 11.0 had higher in microorganisms than the control, and T1 sample had the highest total plate count. Sensory evaluations were significantly higher in the control and T3 than the other samples. Especially, the overall acceptability of T3 was similar to the control. (

This study was conducted to determine the effect of cryoprotectants(sugar, sorbitol, polyphosphate) on quality properties of chicken breast surimi manufactured by pH adjustment(pH 11.0) during frozen storage. Final surimi was divided into experimental units to which the following treatments were randomly assigned: C(Alaska pollack surimi, two times washing, 4% sugar＋5% sorbitol＋0.3% polyphosphate additive); T1(chicken breast surimi, 0.3% polyphosphate additive); T2(chicken breast surimi, 5% sorbitol ＋0.3% polyphosphate additive); T3(chicken breast surimi, 4% sugar＋5% sorbitol＋0.3% polyphosphate additive). All amino acid contents of control were higher than those of all treatments, while T2 was higher in amino acid contents among the treatments. Shear force of all treatments were higher than that of control, but the breaking force, deformation and gel strength were lower. The TBARS(thiobarbituric acid reactive substances) and VBN(volatile basic nitrogen) values of all treatments were lower than those of control, The TBARS values of all treatments were increased with increased storage period. In sensory evaluation, the score of appearance, meat color and overall acceptability of control were higher than those of all treatments, but aroma, juiciness and tenderness were lower than those for all treatments.
