Abstract This study was planned to bio-fortify hen eggs with natural and synthetic apo-ester and canthanxanthin and evaluate physio-chemical quality parameters. Seventy-two laying hens were allocated into two main groups for eighteen natural and synthetic carotenoids fortified different diets. They were weighed and placed into cages to feed diet fortified with apo-ester and canthanxanthin for 44 days. The results showed a significant effect of natural canthaxanthin and apo-ester on egg breadth, albumin height, yolk color, yolk diameter, yolk index, and haugh units. The effect of natural apo-ester on egg length, yolk color, yolk diameter, yolk index and haugh units is also significant. Combination of natural-canthanxanthin and apo-ester significantly affects yolk color, yolk height, yolk diameter, shape index, yolk index and haugh units. A significant effect of synthetic canthaxanthin on egg breadth, shell thickness, albumin height, yolk color, yolk height, yolk diameter, yolk index, and haugh units was noted. The effect of synthetic apo-ester pigments on yolk color, yolk height, yolk diameter, yolk index and haugh unite were also significant. Synthetic canthanxanthin and apo-ester significantly affect shell thickness, yolk color, yolk height, yolk diameter, shape index, and haugh units. Thus, carotenoid feeding can significantly improve the quality parameters of eggs

Abstract Phytonutrients get attention now days due to their wide application and their tendency to improve the productive and reproductive performance in humans. Hydrolysable tannin (HT) is one of these bionutrients. The present study was aimed to investigate the therapeutic effect of HT on the induced polycystic ovarian syndrome (PCOS) in rats. Forty-five adult female rats with 4 to 5 days regular estrous cycle were selected. The PCOS was induced by a single intramuscular injection of Estradiol Valerate 4 mg/rat/kg. The rats were offered 0.5, 1, 1.5 and 2% of HT/kg body weight through oral gavage for two months. The results had shown a reduction (p<0.05) in average feed intake, body weight and weight gain, total oxidative stress and nutrient digestibility in PCOS rats. Similar reduction trend (p<0.05) in serum luteinizing hormone and insulin was observed; while serum follicular stimulating hormone, serum prolactin and total antioxidant capacity were improved (p<0.05). The ovarian histopathology showed no signs of reduction in cystic follicles while no improvement was observed in healthy follicles. The study concluded that the treatment with 1.5% level of HT had shown the best therapeutic potential for weight management, reduction of oxidative stress and improvement in reproductive health of PCOS rats.

Abstract The present study was designed to prepare to wean food by replacing plant proteins with egg proteins. The weaning foods containing 14, 16 and 18% extruded soy proteins were replaced with 0, 25, 50, 75 and 100% egg proteins using whole egg powder. Physicochemical analysis of raw material and weaned products, water activity, bulk density, in vitro study for protein digestibility, color analysis, microbiological analysis, and sensorial evaluation. Protein content significantly (p < 0.05) varied from 13.76% to 19.89% for formulated weaning foods with the highest value in T12. Treatment T5 and T11 exhibited minimum water absorption capacity (1.86 mL/g) and maximum (2.63 mL/g), respectively. Treatment T1 exhibited the highest (0.76 mL/g) values of bulk density, while the treatment T7 and T12 had the lowest values (0.69 mL/g). The maximum in vitro digestibility was observed in treatment T15 (83.8%) while the minimum (65.4%) was observed in treatment T1. The sensorial evaluation results for all the treatments are significantly (p < 0.05) varies with an overall acceptable score. Results indicate that the microbial loads also within acceptable limits. The weaning foods composite animal proteins can be a cost-effective and possible tool to overcome malnutrition among children in developing countries.

Abstract The core objective of this research work was to fortify milk with conjugated linoleic acid (CLA) and to develop yogurt. Cow milk was analyzed for proximate analysis, minerals content, fatty acid profile and CLA content. After chemical analysis, milk was fortified with 1, 2 and 3% of CLA and yogurts were made. CLA fortified yogurts of cow milk was analyzed for proximate analysis, titratable acidity, synersis, pH, viscosity, CLA and sensory evaluation. Results showed that the proximate composition significantly changed particular fat. CLA contents also changed significantly. The value of titratable acidity was changed significantly in all treatments whereas the entire samples showed lower value of pH after 14 days storage. All treatments showed higher values of viscosity at 0 day and decreased significantly at 14th day. Yogurt samples showed the lowest syneresis value after 14 days of storage. All the treatments were showed overall acceptability. The sensory evaluation indicated good sensory and high textural quality with the maximum consumer satisfactoriness. The results showed that CLA fortification can meet recommended CLA dietary intake for health benefits.

Abstract This study was aimed to determine the retention of bioactive fatty acids and oxidative stability of fish powder (FP) supplemented extruded products. The Labeo rohita fish meat was minced, microwave vacuum dried, and extruded. Product formulations containing FP (0-25%) and semolina (75-100%) were optimized using response surface methodology. The maximum bioactive fatty acids retention was 94.84% in the final product. The highest values of polyunsaturated fatty acids (PUFAs) were 87.97% and 85.66% at 25 °C for 30 and 60 days. Maximum TBARS values were 0.42 and 0.44 mg MDA/kg at 25 °C for 0 and 30 days, respectively. The highest carbonyl contents were 6.02, 7.67, 9.37 nmol/mg protein for 0, 30, and 60 days of storage at 25 °C, respectively. The moderate barrel exit temperature (125 °C) and feed moisture contents (20%) and high screw speed (150 rpm), FP (25%) exhibit the highest retention of PUFAs in a product.

Abstract The objective of this study was to optimize the extrusion processing for production of maximum peptides spectra in multigrain flakes. The results showed that maximum peptides spectra were produced at extrusion condition of 160 °C temperature and 100 rpm screw speed and minimum peptides spectra were observed at 120 °C temperature and 300 rpm. Among proximal composition, highest changes were observed in fat content and thus, significantly affected the atherogenicity and thrombogenicity indices of products. The products with higher peptides spectra (16) showed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) (48.63%), ferric reducing antioxidant power (FRAP) (48.63 ± 4.81 mmol Fe+2/g protein) and superoxide radical-scavenging activity (SRSA) (39.05 ± 4.51%). Similarly, higher peptides spectra product showed higher angiotensin converting enzyme (ACE) (86.01 ± 5.22%) inhibition and inhibition of protein denaturation (IP) (38.12 ± 2.89%). Thus optimization of extrusion process for bioactive peptides can be used for production of biological active products and healthily production system.

Abstract A cohort study of 90 days was designed to explore the hypercholesterolemic associated blood pressure with intake of extruded flaxseed powder (EFSP) fortified yogurts. The hypercholesterolemic subjects were distributed into two groups (1 and 2), then blood samples and blood pressure were taken. Descriptive statistics were used for comparison between groups. A significant increase in serum total cholesterol (TC) (6.330.48 to 6.510.04 mmol/dL) and low-density lipids-cholesterol (LDL-C) (5.170.28 to 5.370.47 mmol/dL) was observed in participants consuming plain milk yogurts for 30 days. A significant decrease in TC (6.470.95 to 6.28 ± 0.84) and LDL-C (5.350.29 to 5.130.44 mmol/dL) was observed in the group consuming EFSP fortified sheep milk yogurt. Similarly, a significant decrease in serum TC (6.381.01 to 6.200.98 mmol/dL), and LDL-C (5.301.16 to 4.980.99 mmol/dL) was noticed in the group consuming EFSP fortified cow milk yogurt. The intake of fortified yogurts reduced significantly serum cholesterol associated with blood pressure in both groups.

Abstract Urolithiasis is a disorder of kidneys in which stones formation occur due to the excessive deposition of minerals in the urinary tract. It affects 12% of the population worldwide. Salvia hispanica seeds are rich source of quercetin which has preventive role in renal stone formation. The study objective was to explore scientifically the anti-urolithiatic effect of Salvia hispanica seed’s methanol extract using in vitro and in vivo urolithiasis models. For in-vitro study nucleation, growth and aggregation assays were performed. In vivo study was performed on rats and they were divided into six groups (n=6). Group-I was given vehicle only. Group-II was disease control, treated with 0.75% EG in drinking water which triggered urolithiasis. Groups-III received cystone (750 mg/kg, orally). Groups IV–VI were treated with extract at 100, 300 and 700 mg/kg doses orally once daily. Groups III-VI additionally received 0.75% EG in drinking water. In vitro study revealed concentration dependent increase in percentage inhibition of crystal’s nucleation, growth and aggregation. In vivo study revealed anti-urolithiatic activity by lowering oxalate, calcium, phosphate, sodium and potassium levels in the urine and the serum uric acid, blood urea nitrogen, total proteins and total albumin. Salvia hispanica seeds are good alterative of allopathic anti-urolithiatic drugs to treat urolithiasis.

ABSTRACT This study was designed to find the effect of vitamin E supplementation on growth, serum antioxidant enzymes, and some trace elements in Japanese quail (Coturnix coturnix japonica) under low ambient temperature. A total of 180 day-old Japanese quails were randomly divided into four groups and provided with 0 (group A), 50 (group B), 100 (group C), and 150 IU/kg (group D) vitamin E (dl-α-tocopherol acetate) under an average temperature of 9±0.5 °C for an experimental period of 42 days. The result showed that feed intake per day, body weight, weight gain per day, and feed conversion ratio did not differ significantly between the groups. Serum concentrations of superoxide and glutathione peroxidase were significantly high in birds supplemented with 150 mg/kg of vitamin E. The concentration of aspartate aminotransferase was not significantly affected between the control and treated groups; however, alanine transaminase concentration significantly reduced in group D. Zinc concentration in the blood increased significantly in group D, with no significant effect on copper and manganese between the control and treated groups. Vitamin E at the level of 150 IU/kg of feed improves the blood antioxidant status and zinc concentration, with no effect on the performance traits of quail reared under low ambient temperature.
