abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...
Background and Objectives: Gamma irradiation has been shown as an effective technology to decrease or eliminate microbial contamination in raw and cooked meat products. However, irradiation-induced physicochemical changes are important to accept the technology by meat industries and consumers. The objective of this study was to assess effects of gamma irradiation (0, 2, 4, 6 and 8 kGy) on nitri...
date syrup, date concentrate and date liquid sugar are among the products which are produced from low quality dates in date processing plants. the aim of this research was to investigate chemical characteristics and sensory properties of date syrup, date concentrate and date liquid sugar in comparison with sugar (sucrose) solutions and evaluate possible substitution of sucrose with these date b...
today, by increase in production capacity of dairy manufactures, high amounts of whey is produced as a by product of cheese production. in recent decays, high amount of whey production sometimes up to 8 times more than produced cheese-, its high bod and its environmental problems caused in particular attention to whey processing and its usage in food products. according to promotions occurred i...
many countries have created systems for monitoring food products. however, these systems need paper and label and also, cannot find the origin and final destination of food product. radio frequency identification (rfid) has the capability of monitoring foods completely and track the mentioned points. this technology also can monitor many food products simultaneously. the usage of this system ca...
We have developed a new method to efficiently convert waste biomass (agricultural, municipal, forestry) into biofuels and value-added products. The process is completely chemical in nature, inexpensive, and produces no waste stream. The derived products are non-toxic, biodegradable substitutes for petroleum, both in motor fuels and as renewable chemical intermediates. The technology involves th...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
Biotechnology is a high technology that is bound to play an important role in the future world due to its wide range of applications in different parts of industry, agriculture, medicine, environment and so on. In our country special attention has been paid to biotechnology as a strategic technology. While the production and consumption of genetically modified organisms (GMO) products is witnes...
