A fundamental property of many organisms is an ability to sense, evaluate, and respond to environmental signals. In some situations, generation of an appropriate response requires long-term information storage. A classic example is vernalization, where plants quantitatively sense long-term cold and epigenetically store this cold-exposure information to regulate flowering time. In Arabidopsis th...

The consumption of canned tuna in the country has been increasing and some factors are effective on the chemical and organoleptic qualities of this product during transport. The aim of this project is to study methods to reduce histamine and improve the organoleptic properties of the product. Three thawing methods consisted of immersion, cold water shower and open air has been considered. Besid...

the popularity of non-dairy probiotic products continues to persist as the consumers prefer functional foods satisfying their health needs. among these promising foods, probiotic grape drink would have beneficial effects on modifying gastrointestinal flora and human health. in this study, the pasteurized grape drink was inoculated by three species of lactic acid bacteria (lactobacillus delbruec...

influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. high germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

stability study of biological products plays an important role for determination of product changes in maintenance period and ensuring of safety and efficacy of vaccines. in this research, accelerated and long-term stability study performed for six batches of full and reduced-dose cattle iriba strain brucellosis vaccine that manufactured by razi vaccine and serum research institute as a new vac...

Volatile compounds in Fuji apples harvested at two different maturities were measured at harvest and after 5 and 7 months of cold storage (1 degrees C) in four different atmospheres. When the samples were characterized by both chromatographic measurements of volatiles and responses of an electronic nose, the analyses showed a clear separation between fruits from different storage conditions (a ...

in this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). following treatments, fruits were stored at 0?c and 80 ? 2% relative humidity for 25 days. the weight loss, total soluble solids (tss), titratable acidity (ta)...

exposure to cold work environment is an occupational health hazard and poses adverse effect on workers health, performance and productivity. this study was performed in a cold food-storage warehouse complex in tehran-iran in order to evaluate the workers' exposure to cold stress. twenty nine exposed workers and 33 non-exposed workers as control subject were included in this study. climatic fact...

Background: Blackberry is a seasonal harvested fruit that is also very fragile and perishes quickly. A comparative study was conducted to find out influence of cold storage on physicochemical parameters of wild and cultivated blackberry over a period of 12 days. Methods: The plant materials were composed of the blackberry fruit, including a compound of cultivated blackberry (Rubus spp.), and w...
