Supplementation of vitamin E (α-tocopherol) as an antioxidant into extender is useful to maintain sperm quality during the process cryopreservation by protecting sperms from reactive oxygen species (ROS). This study aims evaluate protective impacts supplementation on motility, viability, and reducing abnormality in Sapera goats. The sample semen used present was obtained fresh good-quality ejac...

Heat coagulation of milk results from a complex series of physicochemical reactions that eventually lead to precipitation or gelation. Viscosity of milk tends to increase upon heating as it approaches the point of coagulation of the proteins, which is the basis for producing high viscosity in super-heated condensed milk. Although viscous property may have been studied extensively in cow fluid m...

Even though fungal proteases under interest, bulk growth during the productions decreases overall mass transfer and consequently yield. In this study, instead of inorganic microparticles, various organic microparticles were used in production medium to prevent bulky increase homogeneity. Results showed that all microparticle additions did not only increased maximum enzyme activity but also decr...

axis was explored. Materials and Methods: Ten male albino wistar rats after anesthetizing by chloral hydrate (0.5 m1/100gr body weights) were cooled to 25oC. Before and just after hypothermia, and once every 24 hours for three days; serum levels of agiotensin I and aldosterone were measured, using the radioimmunoassay method. Plasma renin activity was also determineded by the standard formula f...

The effect of aging the M. longissimus dorsi of 13 impala at 4oC over a ten-day period was investigated. Large variation between animals was observed for the percentages drip and cooking loss as well as for the CIELab colour (L*, a*, b*) values. No trend could be observed for these physical characteristics over time. Means for all traits correspond to that reported in the literature for this sp...

In order to provide health benefits potential probiotic strains must be viable and metabolically active in the product and maintance their activity in gastrointestinal tract (GIT). Therefore, the current investigations are based on protection of probiotics by microencapsulation to increase survival and delivery of bacterial cultures to the GIT. Several reports have shown better survival of enca...

------------------------------------------------------------------------------------------------------------------------------------------------------This study was carried out to assess the proximate composition of Tilapia (Oreochromis niloticus) and Mackerel (Scomber scombrus) treated with varying concentration (1%, 3% and5%) of sodium metabisulphite, sodium benzoate and potassium sorbate dur...

The physicochemical and microbiological qualities of pressurized (500 MPa/30oC/20 min) and pasteurized (90oC/3 min) pennywort juices were determined during chilled storage (4oC) for 4 months. The color parameters and pH values in both processed juices exhibited no changes upon storage. Moreover, it was found that high pressure could preserve various bioactive components including ascorbic acid,...

The effects of ultrasound treatment prior to the vacuum package and modified atmosphere package on physical, microbial and sensory characteristics of beef meat stored at refrigerator 4oC. Sampling was carried out on the 0, 3, 6, 10, 14, 18 and 22 day of storage. The initial bacteria loading was the slight same on all meat samples and microbial load increase over time. The extension of shelf lif...
