Abstract This study focuses on the oxidative changes in lipids and proteins of beef sausages with incorporated a-tocopherol, rosemary extract or their combination during 3 months’ storage at 4°C. For this purpose, sausages were formulated with no antioxidant (Control, C), 200 ppm a-tocopherol (T), 200 ppm rosemary extract (R), and 100 ppm a-tocopherol + 100 ppm rosemary extract (TR). To observe oxidative changes in lipids; peroxide value, thiobarbituric acid reactive substances (TBARS), and total oxidation value (TOTOX), in proteins; sulfhydryl and carbonyl contents were measured. Use of antioxidants and storage time significantly affected oxidative stability of sausages (P<0.05). Antioxidants, individually or in combination, retarded lipid peroxidation and improve the oxidative stability of sausage during storage. The antioxidant combination showed synergistic effect on protein oxidation, as the lowest carbonyl contents were found in TR samples. As a result, a combination of antioxidants with different effect mechanisms could be the better option to prevent oxidative changes in meat products.

Tbars Formation

Banana pseudo-stem (BPS), which is rich in fibre and polyphenols, is a potential functional ingredient for the food industry. In this study, BPS was added at concentrations of 1.5, 3.0, and 4.5 g/kg to a minced pork batter to evaluate its performance as a filler and to pork burger patties to evaluate its performance as a natural antioxidant. The effects of BPS were compared with those of carrageenan and ascorbate, which are a conventional binder and antioxidant, respectively. The performance of BPS was similar to that of carrageenan in terms of the cooking yield and texture of the cooked batter. BPS reduced the brightness of fresh patties and appeared to reduce oxidative discolouration during the frozen storage of raw patties. Moreover, BPS reduced the levels of thiobarbituric acid reactive substances (TBARS) during the refrigerated and frozen storage of cooked patties. A greater decrease in TBARS formation was observed with 4.5 g BPS/kg compared with 0.5 g sodium ascorbate/kg during refrigerated storage. In contrast to ascorbate, BPS promoted the presence of lipid-derived volatile compounds induced by thermal breakdown in the headspace of cooked patties. Nonetheless, this effect was reduced as the amount of BPS in the patties increased. In cooked minced meat products, BPS could increase cooking yields and lipid oxidative stability during storage and might result in a more intense flavour.

Minimizing microbial growth and maintaining overall quality are priorities for intervention strategies that extend the shelf life of fresh, aquatic foods. Four treatments included a control (fresh fillets), water, 50 ppm of acidified sodium chlorite (ASC), and 1,000 ppm of ASC. Fillets were stored at 1 to 2°C for 0, 8, and 15 days. A significant (P &lt; 0.05) interaction between treatment and storage time was observed for psychrotrophic counts. The increase in psychrotrophic counts with storage time was less for fillets treated with ASC, regardless of ASC concentration. Aerobic plate counts were not affected (P &gt; 0.05) by intervention; however, a significant increase in counts was observed during storage (P &lt; 0.05). Fillet pH, moisture, fat, thiobarbituric acid–reactive substances, fatty acid composition, color, cook yield, and shear force were not affected (P &gt; 0.05) by intervention. Thiobarbituric acid–reactive substances decreased (P &lt; 0.05) during storage. Percentages of individual fatty acids were constant, with the exception of C15 and C20:2; they decreased with storage to 15 days. Percent fat, L* (lightness) and b* (yellowness) values, and cook yield increased (P &lt; 0.05) during storage. Fillet pH, moisture, a* (redness) value, and shear force did not change (P &gt; 0.05) with storage to 15 days. Based on these data, 50 ppm of ASC performed equally as well as 1,000 ppm of ASC. The value of ASC is as a decontaminant; however, fillets in this study had low psychrotrophic counts pretreatment (2.3 log CFU/cm2) and posttreatment (2.03 log CFU/cm2), which did not demonstrate ASC's effectiveness as a decontaminant.

Purpose This paper aims to explore the possibility of utilization of Asparagus racemosus as a novel natural preservative in meat products. Design/methodology/approach Chevon sausages were used as a study model and prepared by incorporating different levels of A. racemosus, namely, T1 (0.25 per cent), T2 (0.50 per cent) and T3 (0.75 per cent) and were vacuum packaged and assessed for various lipid oxidative stability and storage quality parameters under refrigerated (4  ±  1°C) conditions. Findings Significantly (p < 0.05) lower thiobarbituric acid reacting substances (mg malonaldehyde/kg) values were observed for the products containing A. racemosus in comparison to control indicating a significant effect on the lipid oxidative stability. The products containing A. racemosus also showed significantly (p < 0.05) lower values for various microbiological characteristics like total plate count (log cfu/g), psychrophilic count (log cfu/g), yeast and mould count (log cfu/g), anaerobic count (log cfu/g) and free fatty acid (% oleic acid) values indicating the antimicrobial and antifungal properties of A. racemosus. No significant (p > 0.05) effect was observed on the cooking yield and moisture content of the products. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the products containing A. racemosus during the entire period of storage. Originality/value A. racemosus successfully improved the lipid oxidative stability and storage quality of the model meat product without compromising the sensorial characteristics and has a great potential as a novel natural preservative in muscle foods.

Lipid And Protein Oxidation

The increased demand for chicken meat products has led to chickens with increased growth rates and heavier slaughter weights. This has had unintentional negative effects on the genetics of these animals, such as spontaneous, idiopathic muscle abnormalities. There has also been a shift in customer preference towards products from alternative farming systems such as organic and free-range. Indigenous purebred chickens, such as the Polverara, show potential in these systems as they are adapted to more extensive systems. The aim of the present study was to characterize the meat quality traits of the Polverara, by comparing the proximate composition and amino acid profile with that of a commercial Hybrid. In addition, the lipid and protein oxidation was analyzed after eight days of storage. A total of 120 leg meat samples, 60 Polverara and 60 Hybrid were analyzed. Polverara exhibited higher protein content, lower lipid content, and a better amino acid profile. These results indicate that the Polverara has better nutritional meat quality. However, Polverara also showed higher levels of lipid and protein oxidation. Therefore, further research is needed, especially in regards to the fatty acid profile and mineral content of the meat, which is known to affect oxidative stability.

Background: Frying is one of the popular cooking methods for the preparation of food especially meat products. However, this process has some adverse effects, such as lipid oxidation that results in deterioration and rancidity of food during preparation and storage. Malondialdehyde (MDA) as a secondary product of oxidation is commonly used as an index of rancidity in food products. However, the level of MDA produced during the frying process varies depending on the type of food. Methods: This study was performed to evaluate the levels of MDA before and after the frying process in different products, including chicken, fish, pan kebab, beef, sausage, and hamburger. Also, the effect of meat content in hamburger was evaluated on the MDA level. The spectrophotometric thiobarbituric acid reactive substances (TBARS) test was used to determine MDA in the food products. Results: The concentration of MDA in the products increased significantly (P < 0.01) after frying in oil. The highest amount of MDA between the products was detected in fried fish (1.24 µM/g). By increasing the percentage of meat in hamburgers, the content of MDA increased in this product. In the hamburger containing 90% of meat, the MDA level was significantly (P < 0.05) higher than others (0.98 µM/g). Conclusion: The results of the present study can provide proper knowledge about the levels of lipid peroxidation and the safety of different fried meat products.

Dry Sausages

Dry sausages are popular traditional meat products. As these products are a rich source of animal fat, there is an effort to improve their fatty acid ratio. The aim of this work was to study the effect of micro-encapsulated n-3 fatty acids added into dry sausages. Samples of dry sausages (Poličan and Vysočina) enriched with unsaturated fatty acids (36 g for 6 kg of mixture) and rosemary extract (0.3 g·kg-1) were made along with control samples. Physicochemical, instrumental analyses were performed, fatty acid profile was measured by gas chromatography, and oxidation processes were monitored by determination of thiobarbituric acid reactive substances. No significant differences (P ≥ 0.05) in quality indicators were found between samples, however, there were differences in oxidation processes. Sausages enriched with unsaturated fatty acids showed an increase in thiobarbituric acid reactive substances (> 2 mg·kg-1 and > 3 mg·kg-1 in Poličan and Vysočina, respectively, compared to control). Sausages enriched with unsaturated fatty acids and also with rosemary extract have the similar concentration of thiobarbituric acid reactive substances as the control. An increase in the proportion of monounsaturated fatty acids and polyunsaturated fatty acids was seen in samples of Poličan supplemented with unsaturated fatty acids in combination with rosemary extract. The addition of rosemary extract had also a significant effect in increasing the proportion of unsaturated fatty acids in samples of Vysočina. From the viewpoint of quality indicators, changes in the properties of the product were not seen in any samples.

The study aimed to assess the effect of herbal additions with antioxidant properties (pepper, thyme and oregano) on the microbiological and oxidative stability as well as the sensory quality of minced poultry meat. Meatballs treatments without additives and treatments with the addition of three types of spices in two forms—dry spices and industrial extracts were examined. Popular seasoning additives of oregano (Origanum vulgare), thyme (Thymus vulgaris) and black pepper (Piper nigrum) at 0.3% of dry herbal or 0.003% as industrial extract were added to minced meat. The microbiological, chemical and sensory tests were performed at specified times and storage temperature. Based on the studied criteria, products maintained constant and adequate quality by up to 10 days while stored in 4 °C. In the case of all tested samples, the overall sensory quality began to deteriorate after 10 days of storage. The preservative role of herbs and extracts in meat products during processing and storage was observed. Oregano and black pepper in both forms maintained good microbial quality and showed their inhibitory effects on the growth of psychrotrophic bacteria. It was observed that dried herbs revealed a stronger antioxidant effect than additives in the form of extracts. The studied dried herbs played an antioxidant, antimicrobial and preservative role in meat products during processing and storage.

Fresh ground beef patties with (1) no antioxidant (control), (2) 0.02% butylated hydroxyanisole/butylated hydroxytoluene (BHA/BHT), (3) 3% dried plum puree, or (4) 0.25% rosemary extract were aerobically packaged, irradiated at target doses of 0, 1.5, or 2.0 kGy (1.7 and 2.3 kGy actual doses), and stored at C. The samples were evaluated for lipid oxidation on 0, 3, 7, 14, 21, and 28 days of storage after irradiation. When compared to the control, all antioxidant treatments were effective in retarding () irradiation-induced lipid oxidation during storage as determined by 2-thiobarbituric acid reactive substances (TBARs) values. Rosemary extracts had the same antioxidant effect () as BHA/BHT in irradiated and nonirradiated beef patties, followed by the dried plum puree treatment. Irradiation increased TBARs values, but no differences were noted in oxidation between irradiation dose levels.
