Free radicals and food irradiation.
Ionizing radiation can be used to control insect and microbial infestation of foodstuffs, inhibit sprouting, delay ripening and reduce the dangers from food-poisoning bacteria. Irradiation produces free radicals, most of which decay rapidly, although some are more persistent. These latter radicals can be detected and characterized by electron spin resonance (ESR). In bone and other calcified ti...
متن کاملFree Radicals in Plastic Food Containers
Free radicals in polymers are produced during synthesis and interaction with catalysts, initiator of chemical reactions, fillers, stabilizers, and other substances which as chemically or physically active remain dissolved in condensed phase of final product. Also γ irradiation causes both immediate and time dependent changes which arise from the presence of long living free radicals. The free r...

To maintain consistency or texture ? to sustain smoothness or prevent the food from separating, caking, or clumping. To improve or retain nutritional value: Enrichment replaces nutrients lost in processing ? this occurs with grains, as some vitamins and minerals are lost in the milling process. Fortification adds a nutrient that wasn't there before and may be lacking in many people's diets. Iod...
