This work overviews works published on the application of pulsed electric fields (PEF) in egg and egg derivatives, grouped by subject, and arranged chronologically in terms of the factor studied (microorganisms, quality aspects, shelf life and structural changes in gel formation properties). The inactivation of microorganisms by PEF in egg is very considerable, 3.5 decimal reductions in egg whi...

quality and safety. Extended shelf life refrigerated foods are foods that have received minimal processing or precooking and have an enhanced but limited shelf life; refrigeration is a key preservation measure. These foods include conventional products, such as luncheon meats and cured meats, as well as a new generation of partially processed refrigerated foods (NFPA, 1988) such as meat, seafoo...

biological reactions of the two-spotted spider mite (tss), tetranychus urticae, were studied on nine cultivars of tomatoes. the spider mites were reared on leaf discs, taken from fruiting stages of the host plants. the effects of feeding on some tomato cultivars, namely: long shelf life, meran (greenhouse cultivars), redclude, western red, imperial, yazd, mazandaran, west azarbaijan and khorasa...

Seventy-three billion chicken eggs are produced annually in the United States. However, less than 0.1% of these eggs are exported. Increasing the shelf-life of eggs may increase export sales. The goal of this research was to determine whether food-grade coatings on eggs may extend shelf-life under refrigerated storage. Four food-grade coatings were selected: paraffin wax, mineral oil, soy prote...

Weak market linkages, unavailability of cold-storage, and the significant loss eggs due to breakage low shelf-life contribute unaffordability consumption in low-income countries like Ethiopia. The effect spray- oven-drying from local (Ethiopian) exotic (imported) chicken breeds on physical, techno-functional, nutritional composition egg-powders were evaluated. Exotic (n = 150) 140) spray/oven d...

This study examined the effect of rapid cooling with air and CO2 on shell egg quality over 14 wk. The 240 fresh eggs were initially heated to 47 C for 24 h in an incubator, cooled using rapid air cooling or CO2 cooling, and then stored in air or CO2 in 250-mL jars for 14 wk. The CO2 levels were recorded of the jar atmosphere, of the egg air cell, and of the egg albumen. The Haugh units of each ...

dehydration, as one of the practical ways to increase the shelf-life and applicability of yoghurt in various foodstuffs, is normally done by freeze drier (fd) which is an expensive and time-consuming process. for these reasons, in the present study the capability of microwave–vacuum drier (mvd), as an alternative process, was investigated. for doing so, the fat free yoghurt samples of 2.2, 4.2 ...
