The effect of meat marinating with aqueous extract of Ilex meserveae dried leaves on dry-aged beef quality was investigated. Shear force, TBARS value, color parameters, fatty acid profile, and sensory properties were evaluated in beef cuts dry-aged for 21 days. The use of Ilex meserveae dried leaves as marinade at 0.5, 1.0, and 2.0% w / v did not affect the shear force and color parameters of dry-aged beef. The marinating of beef cuts with Ilex meserveae resulted in efficient prevention of lipid oxidation without impairing sensory acceptability. Aqueous extract Ilex meserveae can be applied as a natural ingredient in meat marinade to prevent peroxidation.

This review describes the effect of added freeze-dried guelder rose fruit powder (GRFP) on the quality parameter of homogenized meat products (HMP). In this study, the pH, cooking loss, instrumental color (L*, a* and b*), texture profile, TBARS (Thiobarbituric acid reactive substances), antimicrobial assay, polyphenol content and sensory evaluation of HMP were evaluated. Due to the antioxidant activity of guelder rose fruit (the chlorogenic acid dominated among the identified compounds of the fruit), it was observed that, in the samples with the highest amount of the extract, the amount of microorganisms responsible for food spoilage decreased after storage time (14 days, 4 °C). The addition of lyophilized fruits with a low pH value resulted in the highest cooking loss. The results of sensory evaluation show that, along with the increase of GRFP addition, the taste and smell of meat products become less acceptable. The bitter taste of guelder rose fruit can affect the sensory assessment of meat products. This study is of a pilot nature, further research attempts will be made to offset the problems and design certain solutions, e.g., the use of freeze-dried encapsulation and its addition to meat products.

The aim of the present study was to investigate the effect of modifications of pig-feeding by additions of rapeseed oil and the humus-containing mineral additive Humokarbowit&reg, on selected quality parameters of cured ham. Pig hybrids (Polish Landrace &times, Large White Breed) &times, Pi&eacute, train) were used in the feeding experiments. Humokarbowit&reg, was added up to 4%. Rapeseed oil was added at the dosage of 10 g&middot, kg&minus, 1 of complete diet. The physicochemical, technological and sensory qualities of prepared hams were evaluated. Supplementation of pig diet with rapeseed oil and humus-containing mineral additive did not change the technical parameters of the final product, namely, the yield of the production process and weight losses. Cured hams manufactured meat from pigs fed the supplemented diet were brighter and less yellow than cured hams of pigs fed a normal diet. The applied feed modification contributed also to better storage stability of the meat product color. The control and experimental products did not show significant differences in sensory value. Supplementation of pig diets with rapeseed oil and Humokarbowit&reg, increased content of polyenoic&mdash, especially n-3-free&mdash, fatty acids, comparing to control group, as well as ratio between n-6 and n-3 FFA. Used additives were effective as feed component in prevention of changes in the fatty acids content of cured hams during storage. In summary, the addition of rapeseed oil and humus-containing preparation to pig diets had a positive effect on raw meat quality and may have a beneficial effects on human health by increased polyenoic fatty acids content.

The Viburnum opulus (guelder rose) fruit is a Polish native fruit that grows across almost the entire territory of the country, except for the Tatra Mountains. The fruits are rich in nutrients and biologically active compounds, however, they are rarely used for food production or as a dietary ingredient. This study assessed this fruit for dry matter (17.3% ± 0.7), extract (13% ± 0.53), titratable acidity (1.78 g/100 g ± 0.48), pectin (1.10% ± 0.97), vitamin C (47.79 mg/100 g ± 1.02), the amount of sugar identified as fructose (6.85 g/100 g ± 0.67), antioxidant activity, ABTS (14.64 ± 0.61 μM Trolox/100 g), FRAP (211.14 ± 1.04 µM Trolox/100 g) and total polyphenolic content TPC (1695.88 ± 0.86 mg GAE/100 g). The analysis of phenolic identification was performed using the ACQUITY Ultra Performance LC (UPLC) system with the binary solvent manager and PDA detector.

Two groups of finishing borrows (final crossbreeds of (Polish Landrace(maternal) × Large White Breed) × Pietrain(paternal)) were fed a commercial feed (control group CG) enriched with either rapeseed oil or humus-containing mineral preparation (experimental group EG). Samples of tissue fat extracted from Semimembranous muscle contained an average of 12.95 mg/g cholesterol (CG) and 13.14 mg/g (EG). Used feed supplementation had significant effect on the inhibition of cholesterol oxidation process in pork. Sum of cholesterol oxidation products was lower in raw material of pigs fed enriched diet than in those fed only commercial diet. Additionally, cholesterol contained in raw material of finishers fed experimental diet was less susceptible to oxidation during storage. Results showed that samples of EG contain significantly (p ≤ 0.05) less of such compounds as: 7α-hydroxycholesterol, 7β-hydroxycholesterol, 5,6α-epoxycholesterol, 5,6β-epoxycholesterol, 20α-hydroxycholesterol and cholestantriol in comparison with the control group. Results highlight the potential of using rapeseed oil and humus-containing mineral preparation to prevent cholesterol oxidation of pork.

The aim of the study was to evaluate the effect of walnut green husk addition on selected properties of cooked sausages. Walnut green husk (WGH) decreased weight loss during storage of cooked sausages. Color deterioration during storage was smaller when WGH was used in meat products. Hardness of cooked sausages increased along with WGH addition, whilst springiness and chewiness decreased. Walnut green husk added to sausage improved sensory acceptance of smell and texture. Walnut green husk, as low cost source of valuable phytochemicals, demonstrated strong inhibition on microorganisms growth during storage of cooked sausages. In conclusion, walnut green husk can be applied in meat processing as an additive with functional properties.

Bioactive compounds of plant origin are becoming increasingly popular as food ingredients with a beneficial impact on human health. Therefore, the present study aimed to investigate the possibility of using different doses (0.5 g–1.5 g) of cornelian cherry juice (CCJ) as a functional additive in the production of beef burgers. Results of the experiment showed CCJ addition to cause high acidification of the meat emulsion and to decrease meat production yield was unbeneficial from the economic point of view. In contrast, the CCJ was highly effective in retarding lipid oxidation in beef burgers during storage wherein even a dose of 0.5 g CCJ resulted in beneficial inhibition of oxidative changes and at the same time had no negative effect on the sensory characteristics of beef burgers. CCJ can be applied in the meat industry to develop novel products; however, future research is needed regarding its acidifying properties.

The present study was aimed at evaluating the effect of a sea buckthorn (Hippophae rhamnoides L.) fruit extract on selected quality properties of cooked sausages. The ethanolic extract of sea buckthorn fruit (SBE) incorporated at the highest level (3%) significantly affected the pH, weight losses, and instrumental color parameters of sausages. The SBE deteriorated organoleptic properties of sausages like juiciness, overall appearance, texture, and taste; however the sausages manufactured with 1.5% SBE were scored higher for color and almost the same as control for smell acceptance. Textural parameters like hardness, springiness, gumminess, and chewiness of cooked sausages decreased along with SBE addition. After 28 days of storage, the samples with 1.5% SBE addition were as springy, hard, and gummy as the control ones. Incorporation of SBE increased the shelf life of sausages. The highest inhibition of lipid oxidation was observed in the samples manufactured with 1.5% SBE. The SBE significantly improved the microbial qualities of sausages.

The aim of this study was to analyze selected quality characteristics of cooked pork sausages manufactured with the addition of Sea buckthorn (Hippophae rhamnoides L.) berries preparations. Stuffings of model sausages consisted of pork, backfat, water and additives such a curing salt and sodium isoascorbate. Functional additives used in production process were two preparations obtained from dried Sea buckthorn berries in form of powder and brew. Powder of dried berries was added in amount of 1 and 3 g, while water infusion as a replacement of 50 and 100% ice water included in meat products formula. Control samples were produced without functional additives. Experimental stuffings were heat treated in water bath and stored for 4 weeks under cooled conditions (4±1ºC). Physical parameters of colour, texture profile and technological parameters as acidity, weight losses and water activity were estimated. The effect of Sea buckthorn berries preparations on lipid oxidation during storage of final products was determine by TBARS method. Studies have shown that addition of Sea buckthorn preparations to meat-fatty batters significant (P≤0.05) reduced the pH values of sausages samples after thermal treatment. Moreover, the addition of berries powder caused significant differences (P ≤ 0.05) in weight losses after cooking process. Analysis of results of texture profile analysis indicated, that utilization of infusion prepared from Sea buckthorn dried berries caused increase of springiness, gumminess and chewiness of final meat products. At the same time, the highest amount of Sea buckthorn berries powder in recipe caused the decrease of all measured texture parameters. Utilization of experimental preparations significantly decreased (P≤0.05) lightness (L* parameter of color) of meat products. Simultaneously, introduction of 1 and 3 grams of Sea buckthorn berries powder to meat-fatty batter increased redness (a* parameter) of samples under investigation. Higher content of substances reacting with thiobarbituric acid was observed in meat products produced without functional additives. It was observed that powder of Sea buckthorn berries added to meat-fatty batters caused higher protection against lipid oxidation in cooked sausages., {"references":["J. Cheorun., H. S. Jun, B. S.

Evaluation of functional properties of beef heart and lip tissue proteins was based on the data obtained in the following determinations: protein extractability, fat emulsifying capacity, emulsion stability, gel forming ability, and water holding capacity after heat treatment. Beef skeletal muscles were used as the control. It was found that extractability of proteins of the raw materials was low as well as their ability to stabilize emulsions was on a low level. Proteins soluble at high ionic strength (fraction HIS) of beef heart and lip tissue emulsified 80.7 ml and 68.9 ml of oil/100mg of protein, respectively, as compared to 106.6 ml in the control group. Analogically, protein soluble at low ionic strength (fraction LIS) emulsified 77.9 ml, 61.2 ml and 100.4 ml of oil, respectively. Emulsion stability of offal proteins appeared to be dependent on ionic strength. Generally at higher concentrations of salt their ability to stabilize emulsions was better as well as their water holding capacity increased. Their gelation properties as compared to control were also low. In each case, the functionality of cardiac proteins proved to be better than that of beef lip tissue.
