this study evaluated the antibacterial and antioxidant effects of tamarind water solution on shelf life of silver carp ( hypophthalmicthys molitrix ) fillet during refrigerator storage. treatments of this study were unwashed samples (control), and samples washed with 1% and 2% tamarind water solution. microbial, physicochemical and sensory analysis including total viable count (tvc), peroxide v...
we examined the effectiveness of intermittent warming (iw), hot water (hw), salicylic acid (sa), and calcium chloride (cacl2) on the postharvest life of pomegranate fruit cv. ‘shishe-kab’ and extending fruit shelf life during cold storage (3°c). fruit were subjected to cycles of 1 d at 17 ± 1°c every 6 d of storage at 3°c under iw conditions. pre-storage treatments were hw (50°c) for 3 min, sa ...
Due to prolonged storage time of fuel, recognizing the effective parameters on fuel degradation and its shelf life prediction is important. Regard to need of using a reliable and efficient accelerated ageing method for prediction of fuel shelf life, introducing an efficient approach is necessary for this purpose. Most of the researches done in this area are limited to Arrhenius classical approa...
In this study, some physico-chemical characteristics of Iranian tea-seed oil (Lahijan variety) were compared with those of the oils from sunflower seed (Fars variety) and olive (Gilezeytoon variety) in terms of fatty acid contents, peroxide value, iodine value, saponification value, and oil shelf-life. Also the shelf-life of sunflower and olive oils containing 5% and 10% tea-seed oil were compa...

considering the potential benefits of edible coatings and films for storage of food materials, effect of edible calcium alginate film on shelf life of frozen lamb muscles was studied in the present research. microbial analyses including total microorganisms count and psychrophilic bacteria count and chemical analyses such as total volatile nitrogen (tvn) and moisture content determination were ...
Tomato is one of the sensitive fruits to mechanical impacts and physical tensions. The mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 J by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety Shiva F1, includingripening factor...
this study evaluated the antimicrobial activities of two lactic acid bacteria, lactococcus lactis subsp. lactis i23 and lactococcus lactis subsp. lactis e91, against brochothrix thermosphacta in pork meat during storage at ambient temperature (30°c) for 168 h. the lab strains and the spoilage organism were inoculated on fresh pork samples at 1×106 cfug-1. results showed about 3 log reduction in...
background: today, in an attempt to reduce the human exposure to synthetic compounds such as chemical preservatives, some studies aimed at the replacement of artificial preservatives with natural ingredients with natural protective effects. methods: in the present study the microbial inhibition effect of saturejaba chtiarica essential oil in three different concentrations (0.1, 0.05, and 0.025%...
