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%...

In recent years, application of nanotechnology in the food packaging industry has become more widespread and is progressively being commercialized. Adding nano-materials improves polymers` barrier properties for gases such as O2 and Co2, and increases UV rays barrier, mechanical strength, stiffness, stability, and heat resistance of the base polymer. In this study, low density polyethylene film...

In this study, we investigated the effects of an ultrasonically activated stream (UAS) on removal microbial contaminants from spinach leaves. The loads samples cleaned with and without UAS were enumerated using cell culture method compared against unwashed day 0 6 after cleaning. cleaning leaf quality also examined through both macroscopic microscopic inspection, as well measurement electrolyte...

the present study examined the effect of packaging film on the quantitative and qualitative properties of button mushrooms. the three types of packaging tested were a clear polyvinyl chloride box, polyvinyl chloride stretch film and biaxially-oriented polypropylene film (bopp). the five types of moisture absorbers examined were silica gel (2.5 g, 1.25 g), sodium chloride (2.5 g, 1.25 g), and si...

introduction: pharmaceutical companies as well as food and cosmetics manufacturers are legally required to provide a shelf-life label on their products packaging as part of their stability study report. there are different recommended software like r software package and sas which can perform as shelf-life estimating tools for analyzing the data achieved by the stability testing of drugs and va...

infant formula has a fatty acid composition that meets the needs of the neonates for unsaturated fatty acids.these fatty acids are of major importance during this period of life in which the brain and retina are developing, and will therefore have an influence upon visual acuity and learning abilities. oxygen reacts readily with unsaturated fatty acids, so that every time these compounds are ha...
