This experiment was conducted to evaluate the effects of 7 experimental diets (2 diets containing 100 and 200 mg vitamin E (VE)/kg and 5 diets containing 0, 0.5, 1, 1.5 and 2% green tea powder (GTP) ) on performance and breast and thigh meat oxidative stability of broiler chicks during different storage times. A total of 364 male broiler chicks were divided to 28 groups of 13 chicks each. Then ...
a 42-d study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, and the oxidative stability of meat during frozen storage. a total of 324 one-day old broiler chicks were randomly attributed to 6 experimental groups and fed iso-energetic and isonitrogenous diets as follows, c: control (soybean-corn); cs1...
abstract in this study, big-head carp flesh was processed and fish finger was produced by the formula of 1, 2 and 3 with 70, 80 and 93.5 percent of big head fish flesh respectively. then sensory attributes, biochemical changes and nutritional value such as peroxide value (pv), thiobarbituric acid (tba) and the total volatile nitrogen (tvb-n) changes and microbial load of all three formulas were...
The fact that oxidation, as one of the main routes of phase I metabolism of drugs, follows by conjugation reactions, and also formation of nitrenium ion as one of the clozapine oxidation products, directed us to investigate the oxidation of clozapine (CLZ) in the presence of nucleophile. The oxidation of clozapine (CLZ) has been studied on a glassy carbon electrode in the absence and presence o...
Background: In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend shelf life of semi-preserved food. The aim of this paper was to examine chemical and microbiological changes promoted by a traditional marinating process in rainbow trout fillets during frozen storage. Methods: Fish fillets were immersed in traditio...
امروزه اهمیت نگهداری و عرضه ماهی تازه با توجه به علاقه مصرف کنندگان به ماهی تازه نسبت به منجمد روز به روز بیشتر می شود. در این میان تعیین مدت زمان ماندگاری ماهی، جهت تعیین زمان مصرف آن، به دلیل فساد پذیری بالای ماهی اهمیت می یابد. این پژوهش به منظور بررسی روند تغییرات فسادی و تعیین زمان ماندگاری ماهی قزل آلای رنگین کمان (oncorhynchus mykiss) طی نگهداری در دمای یخچال (°c4) صورت پذیرفت. بدین منظو...
The Berberis vulgaris (BV) plant has been extensively used as a traditional medicine in some part of Asian region especially in Western Asia. The BV fruits is claimed also to have anti-viral activities, and as a treatment for chronic candidiasis, indigestion and parasites. The present study was conducted to evaluate the antioxidative activity, nutritional and antinutritional composition of Berb...
electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. the results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. in addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobarbitu...
