This work is concerned with the oxidative stability and sensory characteristics of traditional fermented sausage Petrovsk? klob?sa, produced with the addition of commercial starter culture (SC). Fatty acids profile, thiobarbituric acid-reactive substance (TBARS) values and sensory properties of odor and taste have been determined at the end of drying and after 2 and 5 months of storage. The sum of saturated, unsaturated and polyunsaturated fatty acids was not significantly different (P>0.05) in SC and control sausage at the end of storage. After 5 months of storage TBARS value of SC sausage amounted to 0.57 mg MDA/kg, and it was significantly lower (P<0.05) compared to control (0.84 mg MDA/kg). Also, sensory properties of odor and taste of SC sausage (3.66) were better in comparison to control (3.55). This study demonstrated that the addition of starter culture can hinder lipid oxidation and contribute to the preservation of desirable sensory characteristics of fermented sausages during a long storage period.

The effects of starch (corn and quinoa) and quinoa seeds on chicken meatballs’ physicochemical, textural, and sensory properties were investigated during frozen storage. The chicken meatballs were prepared with corn starch (CS), quinoa starch (QS), quinoa seeds (Q), and combinations of corn starch and quinoa seeds (CS-Q), and quinoa starch and quinoa seeds (QS-Q), which were subjected to five freeze–thaw (F-T) cycles of temperature fluctuation conditions during frozen storage. Regardless of the type used (CS or QS), adding starch resulted in fewer cooking, drip, and reheating losses in chicken meatballs during frozen storage. The values of the hardness, gumminess, and chewiness of chicken meatballs with CS or QS were half those of chicken meatballs without starch, indicating that the addition of starch inhibited the change in the meatballs’ texture. The total volatile basic nitrogen (TVB-N) and thiobarbituric acid reactive substance (TBARS) values were progressive but did not dynamically increase during five F-T cycles. Chicken meatballs containing CS-Q or QS-Q showed significantly lower TBARS values than those with CS, QS, or Q after five F-T cycles. Adding quinoa seeds significantly increased the antioxidant activity and the chewiness of meatballs (p < 0.05) compared with starch only. The addition of the combination of QS-Q to chicken meatballs increased the values of taste, texture, and overall acceptability, indicating that quinoa starch and seeds may be introduced as premium ingredients to frozen meat products.

Abstract In the current research, the use of polyphenols in the production of fermented sausages as a natural preservative and their influence on the sensory characteristics of these products were investigated. Polyphenols could have antimicrobial and antioxidant roles in meat products, but also a range of positive biological effects on consumers. The results of the research showed that the addition of polyphenols did not significantly affect the sensory properties (colour, cross-section appearance, consistency, odour and flavour) of the three groups of sausages (control fermented sausage and two sausage variants, one with nitrite and one without nitrite), and that sausages were highly rated during most of the storage period. In addition, all tested sausages were evaluated as acceptable until the end of the entire storage period, i.e., throughout the 280-day period after sausage production.

In this study, the effects were evaluated of butylated hydroxyanisole (BHA), ascorbic acid (AA) and α-tocopherol (TO) on the stability of raw mechanically deboned chicken patties stored at –20°C for 6 months. pH, thiobarbituric acid reactive substance (TBARS), haem iron (mg/kg), metmyoglobin formation (%) and colour (<I>L*, a*, b*, C*</I> and <I>h</I> values) of patties were measured for 0, 2, 4, and 6 months of storage time. pH values were found to be the highest in the initial storage period. TBARS values were observed to range between 0.33 and 2.40 mg malondialdehyde/kg of sample and the <I>L</I>*, <I>a</I>*, and <I>b</I>* values of the patty samples during the storage period were found to range between 38.14 and 49.52, 9.01 and 20.87, and 7.28 and 14.62, respectively. The haem iron and metmyoglobin contents were found to range between 8.39 and 10.87 mg/kg and 19.26% and 45.91%, respectively. As a result, it is suggested that <I>L</I>-ascorbic acid and α-tocopherol can be added into chicken patty samples in view of the storage quality parameters mentioned above.

Control Group

The aim of the study was to assess the influence of the addition of fish raw materials (roe or fish meat) on the quality and nutritional value of pork pâtés. The control group (n = 4) consisted of pork pâtés, I experimental group (n = 6) of pâtés with 20% addition of roe (perch and pike), and II group of pâtés with 20% addition of fish (perch and pike meat) (n = 6). The pâtés’ pH, color, and profiled texture analysis were instrumentally measured and water, protein, fat, ash, and fatty acid content were determined by reference methods. To assess the oxidative stability of lipids the measurement of peroxide number, thiobarbituric acid reactive substances and content of conjugated dienes and trienes was used. The degree of fat hydrolysis was determined on the basis of acid value. Sensory analysis was carried out using the scaling method, taking into account 12 unit quality characteristics. Products with roe and meat contained less fat (accordingly 15.9% and 14.1%) and showed lower calorific value (accordingly 225.6 and 208.6 kcal/100 g) compared to pork pâtés (20.2% of lipids, 267 kcal/100 g). Moreover, the addition of fish raw materials improved the index of nutritional quality for protein (from 3.2 to 3.9) and beneficially reduced the nutritional index for fat (from 2.2 to 1.9). Fish constituents modified, to a certain extent, the color, texture, and sensory properties of pâtés, while maintaining full acceptability in consumer assessment. The addition of fish roe significantly increased the healthful quality by improving the fatty acid profile of pâtés, in which the significantly highest content of n-3 fatty acids, including eicosapentaenoic and docosahexaenoic acids (accordingly 252.21, 43.17, and 107.94 mg/100 g product), as well the highest concentration of saturated branched chain fatty acids were determined (18.75 mg/100 g product).

The Impact

The aim of the study was to evaluate the possibility of reducing changes in the quality of consumer hen eggs by storing them in various package type and under various temperature conditions (room and refrigeration). The material consisted of 960 chicken eggs packed in cardboard or plastic boxes, 10 pcs in each. Half of the packages were stored at room temperature (21 °C), the rest in the refrigerator (5 °C). The eggs were stored for 28 days qualitatively evaluated at 14-day intervals. The characteristics of whole egg (weight, specific weight, proportion of morphological elements, air cell depth) as well as of shell (weight, color, crushing strength, thickness, density, water conductivity), albumen (height, Haugh units, weight, pH) and yolk (weight, color, pH) were analyzed. The fatty acids profile of yolks was also evaluated as a freshness indicator. Packaging types available on the market, apart from its marketing and eggs protection function, can also influence the quality and stability of the product during storage. The use of plastic boxes can help to maintain higher eggs quality during the storage period, even after a significant extension of the storage time. Eggs stored in plastic boxes at room temperature had very similar results to those stored under refrigeration using conventional cardboard boxes. This effect is probably related to the lower permeability of plastic boxes in comparison to cardboard ones, but detailed research work in this direction is necessary to verify this relation.

The aim of this study was to determine the effect of the addition of spices (garlic, rosemary, thyme, sage or clove) on the chemical and sensory characteristics of burgers elaborated with lamb meat from different locations (L: only leg; LNB 2/3 leg + 1/3 neck and breast). Formulation type (L vs. LNB) modified the chemical composition. L burgers showed lower values of fat, saturated fatty acids, monounsaturated fatty acids and higher moisture and polyunsaturated fatty acids content than LNB samples, with both types of burgers maintaining the nutritional indexes (P/S and n6/n3) within the recommended amounts. Nevertheless, the type of formula did not influence the sensory properties of lamb burgers. By contrast, the spice addition affected these characteristics over the period of time considered in this study. At the end of storage their global quality could be listed in the following order, from major to minor rate: Sage > Rosemary > Garlic > Thyme > Clove burgers.

Raising the dietary PUFA:saturated fatty acids (SFA) ratio has been recommended for the prevention of CVD. However, a high PUFA:SFA (P:S) ratio diet enhances oxidative stress because PUFA are highly susceptible to lipid peroxidation. Thus, we focused on the role of the dietary P:S ratio and peroxidisability index (PI) value on serum and liver tissue and investigated the effects of dietary P:S ratios (0·4, 1·0, and 4·8) with a fixed PI value (81) on serum lipid parameters and hepatic enzyme activities (experiment 1). To elucidate whether those phenomena were unique to the P:S ratio, we examined the effects of dietary PI values (36, 81, 126, and 217) with a constant P:S ratio (1·0) (experiment 2). Female Sprague–Dawley rats weighing 240–280 g were fed experimental diets for 4 weeks. When dietary PI value was maintained at 81, serum HDL-cholesterol (HDL-C) increased with increasing dietary P:S ratio. When the P:S ratio was fixed at 1·0, HDL-C was the lowest with mid–low PI (MLPI) (PI value of 81). In both experiments, serum LDL-cholesterol:HDL-C ratio kept in the range of 0–2. The hepatic superoxide dismutase, catalase, and glutathione peroxidase (GSH-Px) activities and thiobarbituric acid reactive substance (TBARS) concentrations were the highest in the lowest dietary P:S ratio group (experiment 1). GSH-Px, glutathione-S-transferase, and TBARS were the lowest in rats fed the MLPI diet (experiment 2). In conclusion, these results indicate that a P:S ratio of 1·0–1·5 and a PI value of 80–90 in the diet are within a favourable range to reduce the risk of CVD.

Deer blood was hydrolyzed using Alcalase with hydrolysis time ranged form 0 to 6 h, and the degree of hydrolysis (DH) of protein hydrolysates increased with increasing hydrolysis time (P < 0.05). The reducing power, radicals scavenging activities and Cu2+-chelation ability of deer blood hydrolysate (DBH) significantly enhanced with increasing hydrolysis time (P < 0.05). The antioxidant activity of DBH, indicated by thiobarbituric acid-reactive substance (TBARS) values in a liposome-oxidizing system, increased with increasing DH (P < 0.05). The results indicated that antioxidant activity of DBH depended on hydrolysis time, and the hydrolyzed deer blood could be a potent food antioxidant.

Semirefined carrageenan (SRC) plasticized with glycerol (G) and incorporated with antioxidants of 0.4% (v/v) of α-tocopherol and Persicaria minor (PM) extract was successfully developed. The objective of this study is to analyze the antioxidant effect of active packaging films from semirefined carrageenan incorporated with α-tocopherol and Persicaria minor on meat patties. Total phenolic content and antioxidant activity of α-tocopherol and PM extract were measured. The effects of α-tocopherol and PM extract incorporated with SRC-based films on meat patties were evaluated using thiobarbituric acid reactive substance (TBARS) assay, metmyoglobin assay, and pH value for 14 days of storage. The films with 0.4% (v/v) of α-tocopherol and PM extract exhibited a lower lipid oxidation in meat patties compared with that of control (SRC film only, p < 0.05). Also, a brown color development of the meat patties of less than 50% was observed at the end of the 14-day storage. Meanwhile, the pH values for all samples decreased throughout the storage period with the SRC+G+α-tocopherol film showed the highest pH value. Hence, the formulation of SRC film with α-tocopherol or PM extract could be used as an alternative packaging for extending the shelf life of food product with high fat content.
