The aim of this work was to determine the effect of fat and protein oxidation on the colour and texture of Biceps femoris (BF) and Semimembranosus (SM) muscles of smoked dry-cured ham Dalmatinski pršut. Fat and protein oxidation was determined by spectrophotometer methods of which fat oxidation by 2-thiobarbituric acid reactive substances method (TBARS) and protein oxidation by 2,4-dinitrophenylhydrazine (DNPH) method. Colour parameters (L*a*b* values) and texture profile analysis (TPA test) were also analysed. There was no statistical significant difference (P>0.05) between BF and SM in fat and protein oxidation. SM is an external muscle and is more exposed to oxygen than internal muscle BF. As a result of that SM showed slightly higher TBARS values than BF. Slightly higher values of carbonyls in BF can be explained by the higher water content in this internal muscle and thus by the stronger proteolytic activity. BF had higher L*, a* and b* values than SM. Higher values of adhesive force, cohesiveness and stringiness and lower values of hardness, adhesiveness, gumminess, chewiness and fracture were found for BF than for SM.

The influence of muscle type (biceps femoris, BF and semimembranosus, SM) on physicochemical parameters, volatile compounds, and the extent of proteolysis and lipolysis during the manufacturing of smoked dry-cured ham was investigated. A total of fifty smoked hams were sampled: raw ham, after salting, smoking, drying, and ripening. Almost all physicochemical parameters were affected by muscle type, manufacturing stage and their interactions. SM had lower water, ash, NaCl content, and water activity (aw), while fat and protein content were higher after ripening compared to BF. BF showed higher L*a*b* values compared to SM. The results of texture profile analysis showed that almost all analyzed parameters were influenced by muscle type and production stage. A total of 88 volatile compounds were identified, showing an increase in its number during processing: 31 volatile compounds were identified in raw ham and 72 after the ripening phase. Aldehydes and phenols were the predominant groups of compounds, followed by alcohols, ketones, aromatic hydrocarbons, aliphatic hydrocarbons, esters, and terpenes. Muscle type and production phase significantly affected lipid oxidation and the index of proteolysis: in SM, thiobarbituric acid reactive substances (TBARS) increased faster than in BF, while proteolysis had an opposite effect and was more pronounced in BF.

White Striping

The main objective of this research was the development of a healthy meat product from turkey meat with white striping myopathy. The effect of adding different proportions of chitosan on the qualitative characteristics, sensory acceptance, and stability of cooked sausages during storage was studied. Three treatments were elaborated (control, 1.5% chitosan, and 3% chitosan), stored for 56 days, and characterized in terms of chemical composition, texture profile analysis, drip and pressure loss analysis, and sensory analysis (after processing; day 0). In the different storage periods (0 and 56 days), the pH value, color, thiobarbituric acid reactive substances (TBARS), and volatile compounds were evaluated. The results showed that the moisture content, lipids, proteins, and weight loss decreased (p < 0.05) and the ash content increased (p < 0.05) with the addition of chitosan. Similarly, the values of texture parameters (hardness, cohesiveness, gumminess, and chewiness) were higher in the sausages reformulated with chitosan than in control samples. The addition of chitosan increased the pH and yellowness (b*) values and reduced (p < 0.05) redness (a*) and lightness (L*) values. The b* values (only in reformulated sausages) and pH increased during storage, while a* showed a significant reduction after 56 storage days. Lipid oxidation (TBARS) was kept below the limits of quantification in all samples and both after processing and 56 storage days. However, when quantifying the lipid-derived volatiles, a clear antioxidant activity of chitosan was observed, which limits the release of these compounds, mainly aldehydes (hexanal and nonanal). Finally, the sensory analysis indicated that, although chitosan treatments received the lowest scores for all attributes, the reformulated samples did not differ from control sausages. Therefore, sausage containing chitosan may represent an interesting alternative for adding value to turkey meats affected by white striping myopathy and, at the same time, develop into a healthy and functional meat product increasing the proportion of fibers in one’s diet.

Background: The present study was conducted at Livestock farm complex, TANUVAS, Chennai (India) with the objective of comparing the proximate composition and meat characters of three desi chicken breeds viz., Kadaknath, Nicobari Black and Naked Neck chicken. Methods: For this purpose, 60 adult birds (20 each) were maintained on littered floor in separate pens under optimal management conditions. The birds were fed with ad libitum balanced broiler ration and slaughtered after 8 weeks by randomly selecting 6 birds from each breed. Result: Laboratory analysis revealed that there was no significant difference (p>0.05) in the proximate composition of meats among the three native chicken breeds. The total ash content and calcium level was found to be higher in Nicobari Black chicken meat than other breeds and Naked Neck chicken showed the highest value of unsaturated fatty acid. There was significant difference (p less than 0.01) in the physical characters like pH, Water Holding Capacity (WHC), Shear Force Value (SFV), Extract Release Volume (ERV), Thiobarbituric Acid (TBA), Tyrosine Value (TV) texture profile analysis and hunter colour value among the three native breeds. These factors will help us to choose the right native desi breed for development of designer and value added meat products.

The material for the study was the breast muscles of hens after the laying period which were marinated with buttermilk and acid whey for 24 and 48 h. The quality parameters of non-marinated and marinated raw and roast products were evaluated in respect of physical traits (marinade absorption, pH, colour L*a*b*, shear force, TPA texture profile analysis test), microbiological parameters and sensory characteristics. The microbiological parameters were determined as the total viable counts of mesophilic aerobic bacteria of the Enterobacteriaceae family and Pseudomonas spp. Bacterial identification was performed by MALDI-TOF MS. The study showed that marinating the breast muscles of hens after the laying period with buttermilk and whey lightened the colour (p < 0.05), decreased the shear force value (p < 0.05), and reduced hardness and chewiness (p < 0.05) both after 24 and 48 h of marinating compared to the control product. The 24-h time of marinating with buttermilk and whey inhibited (p < 0.05) the growth of aerobic bacteria and Pseudomonas spp. and had a positive effect on the desirable odour, the intensity and desirability of flavour as well as the roast product tenderness. Longer marinating time reduced the product palatability and decreased its microbiological safety. The obtained results suggest that the 24-h time of marinating hen meat after the laying period with buttermilk and acid whey allows to obtainment of a high-quality product.

Along with the growth of the group of consumers paying attention to the relationship between diet and health, there is a trend of interest in natural products and the possibility of their use in meat processing. Raw material used for the study was the breast muscles of pheasants (Phasianus colchicus), which were marinated for 24 hours with acid whey, buttermilk, and lemon juice. Physical parameters (marinade absorption, pH, WHC, colour, shear force, texture profile analysis (TPA), and thermal losses) and microbiological parameters (the number of mesophilic aerobic bacteria, Enterobacteriaceae, Pseudomonas spp., and lactic acid bacteria) of the nonmarinated and marinated muscles (raw and roasted) were evaluated, and sensory analysis was made. The studies have shown that whey and buttermilk can be used as a natural marinade for marinating pheasant meat, as it ensures microbiological safety of the product and has a positive effect on tenderness (measured by shear force) and chewiness. In the sensory evaluation, it improves the juiciness and tenderness of the roast product and has obtained general acceptability.

The spoilage of Sous Vide ‘SV’ cooked salmon stored under refrigeration was studied. Samples were packaged under vacuum in polyamide—polypropylene pouches, cooked at an oven temperature/time of 80 °C/45 min, quickly chilled at 3 °C and stored at 2 °C for 0, 5 or 10 weeks for catering use. Microbial (aerobic and anaerobic psychrotrophs, lactic acid bacteria, molds and yeasts and Enterobacteriaceae), physical—chemical (pH, water activity, TBARS, acidity, L*a*b* color, texture profile analysis and shear force) and sensory (appearance, odor, flavor, texture and overall quality) parameters were determined. SV processing prevented the growth of aerobic and anaerobic psychrotrophs, lactic acid bacteria, molds and yeasts and Enterobacteriaceae. There were no relevant changes in pH, water activity, TBARS, CIELab color associated with cooked salmon spoilage. Instrumental texture data were contradictory. Slight decrease in lactic acid levels was found. In contrast, the SV cooked salmon suffered considerable sensory deterioration during its refrigerated storage, consisting of severe losses of cooked salmon odor and flavor, slight rancidity, discoloration associated with white precipitation, and moderates softness, and loss of chewiness and juiciness. No acidification, putrefaction or relevant rancidity was detected. The sensory spoilage preceded microbiological and physical—chemical spoilage, suggesting that microbiological quality alone may overestimate the shelf life of SV cooked salmon.

Mechanically separated chicken (MSC) from 2 different separation methods (MSC1, Beehive separator, aged bones [Provisur Technologies, Mokena, IL]; MSC2, Poss separator, fresh bones [Poss Design Limited, Oakville, Ontario, Canada]) and chicken breast trim (CBT) were used as raw materials in frankfurters. Texture, color, and lipid oxidation were measured over a refrigerated storage period of 98 d. Both MSC were higher in fat and lower in moisture than CBT. MSC frankfurters had lower L* and higher a* values than CBT frankfurters, with MSC2 frankfurters having the lowest L* and highest a* (P &lt; 0.05). Thiobarbituric acid-reactive substances values were higher in MSC1 frankfurters (P &lt; 0.05) than in CBT and MSC2 frankfurters. Texture Profile Analysis hardness, cohesiveness, resilience, and chewiness were highest in MSC2 frankfurters. Differences among MSC resulted in detectable differences in finished product attributes, with MSC2 frankfurters being darker and redder and having lower levels of lipid oxidation than MSC1 frankfurters, underscoring the importance of understanding the specific functional attributes of MSC obtained by different processes prior to product formulation and manufacturing.

Impact of pretreatment on colour and texture of watermelon rind The effect of osmotic dehydration pretreatment on water loss, solid gain, colour and textural change was investigated. Watermelon rind 1 x 1 cm size was immersed in sucrose solution of 40, 50 and 60° Brix after pretreatment with microwave and conventional boiling in water for 1, 3, and 5 min, respectively. Water loss and solid gain increased with the time of cooking and sugar concentration. Microwave pretreated samples showed higher water loss and solid gain. Increase in the time of cooking decreased the brightness of all the samples. Microwave pretreated samples showed higher ‘b’ values than conventionally pretreated ones. There was no significant difference (P≤0.05) in texture profile analysis parameters except for hardness. Hardness decreased with increase in time of cooking and sugar concentration. Second order regression model was developed for water loss and solid gain of microwave and conventional pretreated watermelon rind.

ABSTRACT Tartary buckwheat peptides (TBPs), produced from tartary buckwheat through solid-state fermentation, were used as a dip treatment solution to preserve tilapia fillets. Fillets were dip treated with different concentrations of TBPs (0.5, 1, and 2% [v/v]) and stored at 4°C for 12 days. The effect of TBPs on thiobarbituric acid, total volatile base nitrogen, surface color, texture profile analysis, total viable counts, and changes in sensory properties of tilapia fillets during storage was investigated. Compared with the control group, the groups treated with TBPs displayed reduced rates of quality deterioration in physicochemical, bacteriological, and sensory characteristics. Based on total volatile base nitrogen content, total viable counts, and sensory scores, the shelf life of control tilapia fillets was 4 days and that for TBP-treated fillets was 8 days, twice as long as that of the control group. Thus, TBPs can be used as preservatives to maintain the quality and extend the shelf life of tilapia fillets stored at 4°C.
