Ruminant meat flavor influenced by different factors with special reference to fatty acids.

Ruminant meat flavor is an important quality and sensory parameter which relays mainly on the organoleptic characteristics of meat. Meat flavor is vital factor for the palatability and acceptability of meat by the consumers. There are various intrinsic and extrinsic factors that influence eating quality of meat. Among these factors, flavor is the major contributor. Fat and low-molecular-weight water-soluble compounds are the most important precursor components in meat, responsible for the meat flavor. The present review focus on the different pre and post-harvest factors that influences the ruminant meat flavor. Raw meat has little flavor but cooking adds value in flavor due to different temperature and cooking methods. The volatile flavoring compounds which are responsible for cooked meat flavor are produced thermally by the Maillard's reaction itself or interaction with lipid oxidation products and vitamin degradation. In nutshell, this review provides perception into previous literature on flavor that affected by various factors particularly the fatty acids and cooking methods.

Acute effects of different dietary polysaccharides added in milk on food intake, postprandial appetite and glycemic responses in healthy young females.

In the present study we compared the postprandial glycemic and satiety responses of different dietary polysaccharides when added in milk (2% M.F.). The objective of this study was to evaluate different polysaccharides against postprandial glucose, appetite responses and food intake at subsequent meal. In a repeated measures design, 30 females (18-30 years) consumed 250 ml milk 2% M.F. (control), or milk with carrageenan (2.5 g), guar gum (2.5 g) and alginate (2.5 g), followed by an ad libitum pizza meal after 120 min. Alginate and guar gum addition resulted in lower caloric intake at subsequent pizza meal. The post-treatment (0-120 min) glucose and average appetite were suppressed by alginate and guar gum (p < 0.0001), with more pronounced effect of guar gum. However, alginate resulted in lower blood glucose (p < 0.0001) compared with control and carrageenan during post-treatment. Alginate and guar gum added beverages would be beneficial in short-term regulation of postprandial glycemia and satiety.

Isolation and antioxidant characterization of theaflavin for neuroprotective effect in mice model.

The mandate of the current investigation was to elucidate the therapeutic and antioxidant perspective of black tea. Purposely, black tea compositional analysis followed by polyphenol extraction and antioxidant characterization was done. Moreover, the theaflavin from black tea extract was also isolated through the solvent partition method. Lastly, the neuroprotective effect of isolated theaflavin was assessed through a bio-efficacy trial. The outcomes delineated that black tea showed promising nutritional composition with special reference to protein and fiber. Among the extraction solvent, ethanol performed better as compared to methanol and water likewise, higher extraction was noticed at 60 min followed by 90 and 30 min. All the extracts indicated antioxidant activity reflected through significant DPPH, TPC, FRAP, and beta carotene as-69.13 ± 3.00, 1148.92 ± 14.01, 752.44 ± 10.30, and 65.74 ± 3.28, respectively. However, isolated theaflavin exhibited higher antioxidant capacity as-737.74 ± 12.55, 82.60 ± 2.33, and 853.77 ± 9.55, for TPC, DPPH, and FRAP, respectively, as compared to extracts. In 15 days' efficacy was physically induced with sciatic nerve injury h sciatic nerve injury physically and treated with isolated theaflavin. A total of 12 healthy albino mice were randomly assigned to either the control (n = 6) or theaflavin (5.0 mg/kg (n = 6)) groups. In these groups, behavioral tests were used to assess and compare enhanced functional recovery as well as skeletal muscle mass measurement. Serum samples included oxidative stress markers. In theaflavin leaves, behavioral tests revealed a statistically significant (p < .001) improvement in sensorimotor function restoration, muscle mass restoration, a substantial decrease in TOS, a significant increase in TAC, and enhanced antioxidative enzyme activity. Considering the above-mentioned therapeutic perspectives of theaflavin, the current research was planned to optimize the isolation of theaflavin from black tea and probed for their neuroprotective effect in mice models.

Valorization of mustard and sesame oilseed cakes for food application through eco-innovative technologies.

Agricultural waste valorization is currently getting attention across the world owing to its environmental impact and rich phytochemistry. The mandate of the current investigation was the extraction and characterization of bioactive moieties from the mustard oilseed cake/meal MOC and sesame oilseed cake/meal SOC through ultrasound extraction (UE) techniques due to its higher yield and less burden on the environment as compared to conventional extraction (CE). Purposely, the MOC and SOC were initially subjected to compositional analysis. Thereafter, bioactive moieties were extracted by using different solvents, that is, ethanol and distilled water, and by applying conventional and ultrasonic extraction techniques. The outcomes indicated that among the techniques, ultrasound exhibited the highest results, and in solvents, ethanol performed better. The treatment extracted with ethanol with UE at 10 min showed the best result for total phenolic contents (TPC) as (6.07 ± 0.03 09 g GAE/100 g MOC) and (7.09 ± 0.04 g GAE/100 g SOC), DPPH radical scavenging activity (67.3 ± 1.9 TE/100 g MOC) & (72.68 ± 1.9 TE/100 g SOC), and FRAP was recorded as (2.83 ± 0.02 g TE/100 g MOC) & (3.56 ± 0.03 g TE/100 g SOC). The higher antioxidant potential showed that the mustard and sesame waste holds significant therapeutic potential owing to its rich antioxidant profile and thus should be utilized for the development of functional products against lifestyle-related disorders. In conclusion, ultrasound is a better technique for maximum as well as accurate extraction, with ethanol exhibiting as a better solvent for this process with more yields as compared to distilled water.
