Surgery to castrate male pigs can be substituted by the manufacture of "entire males". However, the meat of whole male animals may have an unpleasant sexual odor, i.e. - boar taint. The purpose of this paper was to demonstrate how to use masking techniques on meat that has a noticeable boar taint during the processing stage. Smoke has frequently been implicated as a method for hiding boar taint in many types of meat products. Meat items may be smoked naturally using a traditional method or artificially using liquid smoke. Another method for hiding the boar taint in meat products is the addition of spices. Strong-smelling spices, such as paprika, chili, oregano, thyme, rosemary, mint, and cinnamon, can help to mask the stench of swine taint. Also, the use of essential oils in conjunction with spices and herbal extracts helps to mask the boar taint in meat products. Moreover, some of the recent publications focused on the investigation of yeast inoculation as a method for hiding boar taint.

Three Serbian traditional dry-fermented sausages, Sremski kulen (S), Lemeški kulen (L) and Petrovačka kobasica (P), were compared for physicochemical, biochemical and microbiological properties, in order to provide complex overview of their quality and safety. The sausages were produced and analyzed within two production seasons in traditional practice. Water activity, color, texture and proximate composition varied significantly (P

The aim of this study was to investigate textural characteristics of three traditional dry fermented sausages (Sremski kulen, Lemeški kulen and Petrovská klobása) manufactured in different small-scale facilities in northern Serbia, and to correlate them with physicochemical and sensory characteristics. The sample sausages were supplied by different local traditional producers. The textural characteristics were correlated with physicochemical and sensory characteristics using multiple linear regression analysis and principal component analysis. Differences in physicochemical characteristics reflected even more notable differences in texture characteristics. Regarding regression equations, obtained results showed that moisture content was significant for hardness, springiness and cohesiveness. Hardness was also influenced by fat content, while chewiness was influenced by protein content. Principal component analysis separated samples of Petrovská klobása, as the group with the most reproducible analysed characteristics. Obtained results of statistical analyses should provide knowledge for possible improvements of the traditional production, in a way that these sausages could be produced in different facilities with consistent textural characteristics.

The antioxidant properties of Boletus edulis, Cantharellus cibarius and Craterellus cornicupioides decoctions and the effect of mushroom addition on the total phenolic content and the degree of secondary oxidative changes on lipids in frankfurters was studied. Moderate antioxidant activity was obtained by DPPH assay when mushroom decoctions were tested in vitro. Using the conjugated diene method, moderate antioxidant activity was achieved with Boletus edulis and Craterellus cornicupioides decoction, while with Cantharellus cibarius decoction, antioxidant activity was low. Constant amounts of phenolic acid were obtained in frankfurters fortified with Boletus edulis, while lipid oxidation on each tested day was several times less than in the control group of frankfurters, throughout two months of refrigerated storage. Generally, these mushrooms could be used as natural antioxidants to interfere with the chemical deterioration of food products and specifically, to extend the shelf life of cooked pork sausages.

The medicinal herbs of the Balkan Peninsula are highly represented in traditional medicine. The connection between traditional and modern life and health is reflected in the creation of new food products with added value. In this study, the plant species Sambucus nigra L. was used to obtain freshly pressed juice, whose chemical composition and various biological activities were evaluated. The most abundant compounds were phenolic acids: protocatechuic and chlorogenic acid, as well as flavonoids: quercetin-3-O-hexoside, quercetin, and rutin. The analyzed juice was very rich in total phenolic compounds (1945 mg GAE per mL juice), and a significant anthocyanin concentration was observed (30.85 mg Cy-3-GE per mL juice). Bioactivity testing revealed that elderberry juice was an extremely potent agent in the process of neutralizing NO free radicals (53.06 g TE per L juice), while in reducing over-enzyme activity, the best result was achieved in the inhibition of tyrosinase enzyme (54.70 mg KAE per g of juice).

Meat is one of the most nutritious foods that humans can consume, and is defined as the flesh (skeletal muscles) of animals used as food. In addition to protein and fat, meat is a significant source of several micronutrients (minerals and vitamins). Edible offal is also a form of meat which is used as food, but which is not skeletal muscles, and in general possesses higher contents of some micronutrients, especially minerals and vitamins, than muscular tissue. Minerals are the inorganic elements other than carbon, hydrogen, oxygen and nitrogen, which remain behind in the ash when food is incinerated. They are usually divided into two groups – macrominerals (main elements) and microminerals (trace elements) or into three groups – main elements (macrominerals), trace elements (microminerals) and ultra-trace elements. The aim of this paper is to provide an overview of the existing literature on the content of nine most abundant minerals (potassium, phosphorous, sodium, magnesium, calcium, zinc, iron, copper and manganese) in the major raw pork meat cuts (tenderloin, ham, loin and shoulder) and edible offal (tongue, heart, lungs, liver, spleen, kidney, brain and spinal cord) from indigenous pigs. The mineral levels in raw pork meat and pig edible offal are variable, ranging from 175.7 to 463.8 mg/100g for potassium; 159 to 502.0 mg/100g for phosphorous; 38.11 to 158.4 mg/100g for sodium; 8.3 to 28.5 mg/100g for magnesium; 4.61 to 26.02 mg/100g for calcium; 0.67 to 6.47 mg/100g for zinc; 0.55 to 45.59 mg/100g for iron; 0.10 to 0.825 mg/100g for copper; and from 0.0038 to 0.338 mg/100g for manganese. Keywords: minerals, pork, edible offal, indigenous pigs

Early post-mortem, objective and non-destructive prediction of tissue distribution in the major pork cuts is a challenge for the meat industry. Mathematical models to predict pig carcass composition using total lean meat percentage and carcass weight were evaluated in this study. The data were obtained from 455 cold pig carcasses which were dissected according to the EU reference method; total lean meat percentage and carcass weight ranged from 42.45 to 69.21% and from 23.26 to 55.22 kg, respectively. Developed empirical models gave a reasonable fit to the experimental data and successfully predicted the carcass composition and tissue distribution in primal cuts. The second order polynomial models showed high coefficients of determination for prediction of experimental results (between 0.612 and 0.929), while the artificial neural network (ANN) model, based on the Broyden-Fletcher-Goldfarb-Shanno iterative algorithm, showed better prediction capabilities (overall r(2) was 0.889). The newly developed software, based on ANN model is easy, fast, cheap and with sufficient precision for application in the meat industry.

This study investigates the effects of sodium nitrite replacement by the sage essential oil (SEO), on the physico-chemical, microbiological and sensory quality of dry fermented sausages (DFS) during 225 days of storage. The SEO (0.00, 0.05 and 0.10 µL/g) was added in DFS batters formulated with different levels of pork back fat (15% and 25%) and sodium nitrite (0, 75 and 150 mg/kg). The inclusion of SEO had no negative impact on pH, color (instrumental and sensory) and texture parameters. Total plate counts were lower than 6 log CFU (colony forming units)/g in all samples throughout the storage. Furthermore, the addition of SEO at concentration of 0.05 µL/g provided acceptable TBARS (2-Thiobarbituric acid reactive substances) values (&lt, 0.3 mg MDA (malondialdehyde)/kg) in the samples produced with reduced levels of sodium nitrite (0 and 75 mg/kg) without negative alternations on sensory attributes of odor and flavor. Generally, our findings confirmed that the usage of SEO could be a good solution to produce healthier DFS with reduced levels of sodium nitrite.

Daily consumption of fruits/vegetables has a preventive effect against several chronic diseases, mainly because of their bioactive compounds (BACs) and potent antioxidant activity. As consumers demand more of the health-promoting products, it would be a great challenge to enrich these products with functional ingredients that they do not naturally possess, such as lipophilic BACs, probiotics, proteins/peptides, and so on. Currently, a great potential in the field of food innovation can be achieved through 3D food printing (3DP). This is a technique for producing three-dimensional food products of any shape and dimension, with preferred flavors, and desired nutritional compositions. 3DP could be a promising tool to incorporate sensitive and easily degradable BACs and other functional ingredients into functional 3DP food products, making a great contribution to healthy food production. Therefore, 3DP could contribute greatly to increasing the consumption of fruits and vegetables and promoting health. Other advantages of 3DP include time and energy savings, sustainability, and personalized, reproducible food production. However, the safety of 3DP foods has been less extensively addressed. Nevertheless, the use of innovative non-thermal technologies can extend the shelf-life and nutritional value of 3DP foods. In conclusion, the application of 3DP in food manufacturing could overcome major limitations of traditional manufacturing and provide solutions to the challenges of processing fruit-based functional foods.

There has been a great interest in the use of natural antioxidants in food production in order to replace synthetic ones. Synthetic antioxidants can have adverse health effects. Therefore, antioxidants isolated from Mediterranean herbs could be an adequate replacement. Antioxidants from plant sources are valuable bioactive compounds with proven potential for use in the food industry, especially in meat processing, where they are used as natural antimicrobials to extend the shelf life. Various extraction procedures can perform extraction of biologically active compounds (BACs) and essential oils (EOs) from plants. Innovative green techniques, which are considered as environmentally friendly due to decreased use of synthetic and organic chemicals, shorter operating time, better yield and quality of extract, energy savings, and lower costs, have been lately established. Concerning increasing overall yield and selectivity of BACs and EOs from Mediterranean herbs, ultrasound-assisted extraction (UAE), microwave-assisted extraction, and supercritical fluid extraction (SFE) have been the most studied methods. Therefore, this chapter summarizes the novel findings on the use of these technologies to recover BACs/EOs from Mediterranean herbs for products with high bioactive potential for further industrial use.

The medicinal herbs of the Balkan Peninsula are highly represented in traditional medicine. The connection between traditional and modern life and health is reflected in the creation of new food products with added value. In this study, the plant species

The effect of Juniperus communis L. essential oil (JEO) addition at concentrations of 0.01, 0.05 and 0.10 &micro, L/g on pH, instrumental parameters of color, lipid oxidation (2-Thiobarbituric acid reactive substances (TBARS)), microbial growth, texture and sensory attributes of dry fermented sausages produced with different levels of fat (15 and 25%) and sodium nitrite (0, 75 and 150 mg/kg) was assessed. Reduced level of sodium nitrite (75 mg/kg) in combination with all three concentrations of JEO (0.01&ndash, 0.10 &micro, L/g) resulted in satisfying physico-chemical (color and texture) properties and improved oxidative stability (TBARS &lt, 0.3 mg MDA/kg) of dry fermented sausages produced with 25% of fat. However, sausages produced with 0.10 &micro, L/g of JEO had untypical flavor. No foodborne pathogens (Escherichia coli, Listeria monocytogenes, Salmonella spp. and sulfite-reducing clostridia) were detected in any sample throughout the storage period (225 days). The results of this study revealed significant antioxidative activity of JEO and consequently its high potential as effective partial replacement for sodium nitrite in dry fermented sausages.

Functional nutrition, which includes the consumption of fruit juices, has become the field of interest for those seeking a healthy lifestyle. Functional nutrition is also of great interest to the food industry, with the aims of improving human health and providing economic prosperity in a sustainable manner. The functional food sector is the most profitable part of the food industry, with a fast-growing market resulting from new sociodemographic trends (e.g., longer life expectancy, higher standard of living, better health care), which often includes sustainable concepts of food production. Therefore, the demand for hurdle technology in the food industry is growing, along with the consumption of minimally processed foods, not only because this approach inactivates microorganisms in food, but because it can also prolong the shelf life of food products. To preserve food products such as fruit juices, the hurdle technology approach often uses non-thermal methods as alternatives to pasteurization, which can cause a decrease in the nutritional value and quality of the food. Non-thermal technologies are often combined with different hurdles, such as antimicrobial additives, thermal treatment, and ultraviolet or pulsed light, to achieve synergistic effects and overall quality improvements in (functional) juices. Hence, hurdle technology could be a promising approach for the preservation of fruit juices due to its efficiency and low impact on juice quality and characteristics, although all processing parameters still require optimization.

Pathogens from the genus Salmonella belong to the group of the most common food poisoning causative agents. The present paper investigated the effect of the basil and rosemary essential oils as well as their combination on the growth of Salmonella enterica subspecies enterica serovar Enteritidis (Salmonella Enteritidis) in chicken meat, together with their spoilage protective potential at the two storage temperatures. Food model experiments included investigation of their effect to accompanying microbial flora on fresh meat, while anti-salmonella activity was evaluated on artificially inoculated raw and thermally processed meat. The tests were performed in two storage conditions, +4 °C (usual meat storage temperature) and +18 °C (room temperature, which favors the spoilage of investigated meat samples and development of food pathogens). Beside evaluation of microbiological status, physico chemical tests relevant as meat quality indicators (pH, colour, texture, thiobarbituric acid, cooking loss), as well as sensory evaluation of the studied meat samples were performed. Changes in normal flora pointed to significant effect of both oils against microbial meat spoilage, where various groups were affected by different treatments. In addition, all the treatments reduced the number of salmonella cells in comparison to the control samples. Obtained results on the physico-chemical parameters highlight their applicative value since they showed either beneficial effect either did not caused any notable meat quality changes.

The effect of sage essential oil (SEO) and sage extract (SE) obtained from sage (Salvia officinalis L.) herbal dust (food industry by-product) on microbiological and oxidative stability of fresh pork sausages was investigated. pH, microbiological analysis, TBARS value and sensory panel scores were assessed. Oxygenated monoterpenes, oxygenated sesquiterpenes and diterpene polyphenols were the most abundant compounds present in SEO and SE samples. SEO and SE addition resulted in significant (p

The aim of this study was to determine colour characteristics (lightness - L* , redness - a* and yellowness - b* ) of dry fermented sausage Petrovska klobasa smoked in traditional (T - direct smoking) and industrial (I - indirect smoking) conditions, at the end of drying period and the end of storage period. Also, the content of polycyclic aromatic hydrocarbons -PAH (acenaphthylene, fluorene, phenanthrene, anthracene, pyrene, benz[a] anthracene chrysene, benzo[ b ]fluoranthene, benzo[k]flouranthene, benzo[a] pyrene, indeno[1,2,3- cd ]pyrene, dibenz[a,h]anthracene and benzo[ghi] perylene) from Environmental Protection Agency list (US-EPA) were determined in both examined groups of sausages. According to the results obtained in this study, Petrovska klobasa smoked in traditional conditions had significantly lower (P a* ) at end of drying period, but colour characteristics ( L*; a*; b* ) were not significantly different (P > 0.05) at the end of storage period comparing to sausages smoked in industrial conditions. Also, Petrovska klobasa smoked in traditional conditions at both examined periods had significantly higher total content of 13 US-EPA PAH (118.7 μg/kg; 168.0 μg/kg respectively) comparing to sausages smoked in industrial conditions (30.5 μg/kg; 61.3 μg/kg respectively).

In this paper, the application of a biopolymer coating based on chitosan was tested. The optimized coating was formed as a two-layer coating, wherein the first layer (which is in contact with the product) was formed of chitosan with emulsified caraway essential oil as an active component, whereas the second layer was formed of chitosan with the addition of beeswax to optimize the moisture barrier of the coating. As a substrate, the traditional dry fermented sausage Petrovská klobása was selected. The coating was applied to the sausage after drying. During two months of storage under controlled conditions, the influence of the coating on the loss of moisture, the oxidative stability and the sensory characteristic of aroma of the control sausage (without the coating) and sausage with the coating was monitored. The results obtained indicate a significant contribution of the applied dual layer chitosan-based coating to the preservation of the sausage quality parameters analyzed.

The effect of thyme supercritical extract on oxidative stability of precooked and cold-stored (at 4°C for 6 days) pork chops was analysed. Thyme extract was applied with a marinated process (SF1), or was introduced on the surface of the chops after cooking (SF2). Thyme extract in SF1 samples showed a significant protective effect towards oxidation of lipids during the cooking process. Both processes of thyme application showed potential for lipid oxidation inhibition throughout the refrigerate storage period of precooked pork chops, thus protecting colour and sensory characteristics of the samples. Finally, at the end of storage period, the lowest oxidative changes were determined for SF1chops.

Concentrations of mercury (Hg) were analysed in livers (n = 26) and kidneys (n = 26) of female cattle (412–2502 days old) from farms for milk production in the area of Vojvodina. Concentration of Hg was analysed by ICP-OES, after digestion by microwave. The Hg concentrations in the livers and kidneys ranged from below detection limits (LOD < 0.006 mg/kg) to 0.206 mg/kg wet weight and from below detection limits (LOD < 0.006 mg/kg) to 0.018 mg/kg wet weight, respectively.

The usage of food additives is one of the key methods for inhibiting microorganisms’ growth and delaying oxidative changes in dry-fermented sausages (DFS). However, they have numerous negative health effects, so the novel meat industry is oriented towards different natural alternatives while focusing on plant extracts, including essential oils (EOs). EOs are interesting since they are generally recognized as safe (marked as GRAS) and have a broad acceptance from the consumers. Their activity depends on numerous parameters including the method of extraction, concentrations and possible synergistic effects of their bioactive compounds. Various conventional (hydrodistillation and organic solvent extraction) and novel (microwave-assisted, ultrasound-assisted and supercritical fluid extraction) extraction techniques are being applied for EO recovery, and optimization of these process is an essential step towards cost-effective production of high-quality extracts. Generally, it can be concluded that EOs are added into DFS to delay or prevent lipid oxidation, retard microorganisms’ growth, improve colour stability and extend the shelf-life.

The aim of this paper was to examine the effect of chitosan coating with the addition of caraway essential oil and beeswax on lipid oxidation protection, as well as aroma and water content preservation of traditional dry fermented Petrovska klobasa sausage. During the entire storage period, TBARS index value in coated sausage was lower compared to the control (P

The effects of wild thyme by-products (Thymus serpyllum L.) from supercritical fluid extraction SFE1 (100 bar and 40 °C) and SFE2 (350 bar and 50 °C) on the quality of ground pork patties evaluated by pH, CIE-color, lipid (TBARS test) and protein oxidation (thiol group content) and microbiological profile. SFE extracts were added to ground pork patties as: 0.075 μL/g of SFE1 (T1), 0.150 μL/g of SFE1 (T2), 0.075 μL/g of SFE2 (T3), 0.150 μL/g of SFE2 (T4), while SFEs (T5) was control without any extracts. SFE1 and SFE2 were protective against color degradation. Moreover, the addition of SFE1 and SFE2 significantly reduced lipid and protein oxidation in the patties (p ≤ 0.05). Furthermore, lower concentration of SFE2 reduced total plate count to

Sage has various biological activity and long tradition of the using in phytopharmaceutical preparations and, recently, in food industry. In this work, the essential oil obtained by hydrodistillation and essential oil and extract obtained by supercritical fluid extraction from sage herbal dust, waste product of filter tea factory, were screened for antimicrobial activity against Escherichia coli in the medium which simulates the conditions in meat and in real system of minced pork. The supercritical fluid extract had much lower effect to the reduction of a number of E. coli in meat simulation medium. The total inhibition of E. coli growth was achieved after 12 h and 24 h with the addition of 0.6 μl/ml of essential oil obtained by hydrodistilation and supercritical fluid extraction, respectively. The addition of essential oils and supercritical fluid extract of sage herbal dust could be used for the effective control of E. coli growth in minced meat.

The aim of this study was to investigate the influence of the anatomical location of muscles on their physical characteristics and proximate and mineral composition. Physical (pH value, water-holding capacity − WHC, and instrumental colour − CIE L*a*b* values) characteristics and proximate (moisture, protein, total fat and total ash) and mineral (K, P, Na, Mg, Ca, Zn, Fe, Cu, Ni and Mn) composition were determined in four ( M. psoas major − PM, M. longissimus dorsi − LD, M. semimembranosus − SM, and M. triceps brachii − TB) muscles of Saanen goat male kids. Many significant or numerical differences were found in the mean values of quality characteristics among the particular muscle types. Muscles had no significant influence ( P > 0.05) on Mg, Ca, Ni and Mn content. The PM muscles were the highest in pH 24 h (5.83), CIE a* (22.47, reddest muscle), CIE b* (5.90) values, moisture (77.61 g/100 g), Na (78.2 mg/100 g), Fe (1.57 mg/100 g), Cu (0.131 mg/100 g) and Mn (0.013 mg/100 g) content and had the highest WHC, darkest colour (CIE L* = 38.03), and lowest content of total fat (1.40 g/100 g), K (330 mg/100 g) and Ni (0,019 mg/100 g). The LD muscles were the highest in K (392 mg/100 g), Mg (26.1 mg/100 g), Ca (11.8 mg/100 g) and Ni (0.030 mg/100 g) content, and the lowest in CIE a* (14.71) and CIE b* (3.84) values, total ash (1.15 g/100 g), Zn (2.24 mg/100 g), Cu (0.092 mg/100 g) and Mn (0.011 mg/100 g) content. The highest content of protein (20.69 g/100 g), total ash (1.20 g/100 g) and P (255 mg/100 g), and the lowest pH 24 h (5.68) value, WHC and moisture (76.42 g/100 g), Na (64.2 mg/100 g), Fe (1.07 mg/100 g) and Mn (0.011 mg/100 g) content were found in SM muscles. The lightest colour (CIE L* = 44.02), the highest content of total fat (2.15 g/100 g), Zn (3.21 mg/100 g) and Mn (0.013 mg/100 g), and the lowest content of protein (19.29 g/100 g), total ash (1.15 g/100 g), P (223 mg/100 g), Mg (24.3 mg/100 g) and Ca (10.6 mg/100 g) were found in TB muscles. Significant relationships between quality characteristics of meat in number of cases were determined. This study was undertaken to increase the available information on the physicochemical traits of goat meat. This is important to provide, update and improve regularly nutrient composition data of goat meat.

Concentrations of cadmium (Cd) and lead (Pb) were determined in livers (n = 52) and kidneys (n = 52) of female cattle (345–2717 days old) from dairy farms in the region Vojvodina. Cd and Pb were analysed by inductively coupled plasma-optical emission spectrometry, after microwave digestion. Cd and Pb concentrations did not exceed the Serbian and European maximum set limits in any sample. The Cd concentrations in the livers and kidneys ranged from 0.033 to 0.151 mg kg−1 wet weight and from 0.055 to 0.510 mg kg−1 wet weight, respectively. The corresponding Pb concentrations were 0.015-0.159 mg kg−1 wet weight and 0.021-0.196 mg kg−1 wet weight, respectively. Mean Cd and Pb concentrations were significantly lower (p

To compare quality traits of longissimus lumborum muscle of three genotypes, 20 White Mangalica (WM), 20 crossbred Duroc × White Mangalica (DWM) and 20 Large White (LW) pigs were allotted to the same indoor rearing and feeding conditions. Crossbred and LW pigs grew faster than WM pigs reaching 150 kg on average 168 and 288 days before WM, respectively. Meat from WM pigs had the highest intramuscular fat content and darkest and reddest colour; crosses were at an intermediate position, with significant differences among all genotypes. In addition, ultimate pH, water-holding capacity and iron content were significantly the highest in meat from WM pigs, compared to the other two genotypes. Crossing WM with Duroc had a significant effect on individual fatty acid content of meat. However, the sum of saturated, monounsaturated and polyunsaturated fatty acids remained unchanged. WM and DWM pigs had significantly more tender meat than LW pigs. Monounsaturated fatty acids (MUFAs) were most abundant, followed by saturated (SFAs) and polyunsaturated fatty acids (PUFAs) in meat from all animals. Meat from WM and DWM pigs had a significantly higher percentage of MUFAs and significantly lower percentage of SFAs than LW pigs.

Physical (pH and L*a*b* values) and chemical (moisture, protein, total fat, total ash, K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn) characteristics of offal consisting of the tongue, heart, lungs, liver, spleen, kidney, brain, and spinal cord of free-range reared Swallow-Belly Mangalica pigs were determined. Many significant differences were found among mean values of quality traits. However, except for a few cases, the determined offal quality traits were in the characteristic ranges reported in the literature. Lungs were high in pH24h (P

The effects of winter savory essential oil (EO) and supercritical extracts (first extract 100 bar, 40 °C – SF1, second extract 300 bar, 40 °C – SF2) on oxidative stability of precooked and cold-stored (at 4 °C for 6 days) pork chops were analyzed. Winter savory showed a significant protective effect towards lipid oxidation which occurs during the cooking process. EO and SF1 showed almost the same potential of lipid oxidation inhibition throughout the whole storage period, being higher comparing to SF2. At the end of storage period the TBARS values were 2.42, 1.66, 1.48, 2.06 mg MDA/kg for control, EO, SF1 and SF2, respectively. Also, EO and SF1 showed better antioxidant potential against protein oxidation comparing to SF2. The lowest colour change at the end of storage was determined for SF1 sample. Samples EO and SF1 had better scores for sensory rancidity; where EO had more pronounced odour and flavour of winter savory and SF1 had lower impact in changing dominant aroma, but preserved aroma of cooked meat. Hence, extracts obtained by supercritical fluid extraction, as natural and environmentally friendly technology, could be used to prolong shelf-life of precooked pork.

The effect of supercritical fluid extract of tomato pomace (TP) and essential oil of organic peppermint (PM) on pH, color, residual nitrite content, lipid oxidation (TBARS value) and total plate count (TPC) of cooked pork sausages produced with 50 mg/kg of sodium nitrite was investigated. Five batches were produced: T1: 100 mg/kg of sodium nitrite; T2: 50 mg of sodium nitrite; T3: 50 mg of sodium nitrite and 0.150 µL/g TP; T4: 50 mg of sodium nitrite, 0.075 µL/g TP and 0.075 µL/g PM; T5: 50 mg of sodium nitrite and 0.150 µL/g PM. The lowest residual nitrite content and TBARS value were observed in treatment T4. The inclusion of TP increased redness of cooked pork sausages. TPC was the lowest in treatment T5. The results of this study showed that the addition of TP and PM enhanced quality of cooked sausages produced with reduced level of sodium nitrite.

Goats, the earliest ruminant to be domesticated, are traditional sources of meat, milk, fibre, leather, related products of animal origin and as draught and pack animals. Meat is the major product of the goat. Meat quality is the sum of all sensory, nutritive, technological and hygienic-toxicological factors of meat. The aims of this study were to investigate the chromium content of four different muscles (M. psoas major, M. longissimus dorsi, M. semimembranosus and M. triceps brachii) of Saanen goat male kids and to determine whether the chromium contents differed between the muscles. Chromium content was determined using inductively coupled plasma optical emission spectrometry (ICP-OES), after dry ashing mineralisation. The studied muscles did not significantly differ (P >0.05) with respect to chromium content. The chromium content ranged from 0.012 to 0.067 mg/100 g, with an average of 0.026 mg/100 g.
