external and internal changes in fruits during storage time are affected by the various factors that some of them can by studied by measuring the qualitative parameters (physical and mechanical). the effects of storage time on some physical and mechanical properties of valencia orange were investigated. the experiment was performed as factorial based on completely randomized design. analysis of...

in this study, the effect of green tea extract was studied on quality of surimi produced from fish silver carp during refrigerated storage. surimi was prepared and immersed with various concentrations of tea extracts (0, 2 and 4%). samples were refrigerated for 15 days and were performed chemical tests include ph, total volatile bases nitrogen (tvb-n), thiobarbitoric acid (tba) test and total b...

in this research, anti-microbial activity of ethanolic extract of licorice root against food spoilage microorganisms (lactobacillus delbrueckii, leuconostocmesenteroides, candida krusei, saccharomyces cerevisiae) in an orange flavored carbonated soft drink was investigated. the mic and mbc of extract against lactobacillus delbrueckii was 0.7 mg/ml and 0.8 mg/ml respectively, and against leucono...

oxidative stability of walnut (juglansregia l.) was evaluated over a period of 1 year storage in various conditions. the whole walnuts, walnut kernels, walnut chopped kernels, walnut kernels packaged in polyethylene (pet) under vacuum and poly propylene (pp) contain of co2 were kept in a normal condition (temperature, 19-30˚с and relative humidity (rh), 35-45%). the whole walnuts and walnut ker...

Physical properties of actomyosin from either fresh or stored platelets have been compared. Actomyosin obtained from platelets after 3 days of storage contained myosin that was 60-80% degraded to myosin rod. No myosin rod was detected in fresh platelets. The platelet myosin rod is similar to the rod produced by limited proteolysis of skeletal muscle myosin.

For measurement of plasma enzyme stability, 18 specimens of whole blood, plasma, and serum from normal subjects were stored at different temperatures. Eight enzymes were assayed after different times of storage: acetytcholinesterase, pseudocholinesterase, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactic dehydrogenase, acid and alkaline phosphatases, and amylase. At _200 ...

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
