The goal of this research is recognition of species of pollution and a rough estimate of rate of transmitted pollution through northern Iran rivers to Caspian sea. Sampling from 3stations up-river, mid-river, and down-river in Lavij rood, Gland rood, and Sabze rood in a 6 month period from 2008/5/22 to 2008/11/22 coincides with warm, low rain, cold and rainy seasons and parameters as temperatur...

A systematic experimental procedure for fish shelf-life modelling was used to develop a model for predicting the quality of fish in the chill chain. For this, the growth of the naturally occurring bacteria pseudomonads, Shewanella putrefaciens, Enterobacteriaceae, lactic acid bacteria and yeasts, on gilt-head seabream (Sparus aurata), was studied at temperatures from 0 to 15 degrees C. The resu...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

In this study, the sensory, microbiological, and biochemical qualities were used to examine quality of Pacific white shrimps (Litopenaeus vannamei) preserved at 0°C during a 10-day period. The sensory was evaluated by index (QI) that resulted from method (QIM) scheme. Meanwhile, total viable count (TVC) K-value assess microbiological shrimp. On day 9, results TVC QIM have shown shrimp showed si...

Effect of retort processing on the shelf life and safety of ethnic Indian food product namely soya peas curry was investigated. Ready-to-eat soya peas curry was packed in laminated retort pouches and processed in a steam-air retort with overriding pressure. Time-temperature profile of processing was determined and the same was used for heat penetration characteristics. The thermal processing pa...

in order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in iran, random samples were taken for one year with the cooperation of the iranian standard and industrial research institute (karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable conta...

Quality assessment of finfish fillets during storage is important to be able to predict the shelf life of the fresh product during distribution. Microbial, chemical (pH, TMA, and TVB-N), and sensory (Quality index assessment QIA, Torry scheme) changes in vacuum-packaged blue-spotted emperor (Lethrinus sp), saddletail (Lutjanus malabaricus), crimson snapper (Lutjanus erythropterus), barramundi (...
