Chemigum P83 elastomeric modifier is for plasticized PVC, which improves mechanical properties and melt processing. It helps the end use application to resist abrasion, flex-fatigue, chemicals, oils and fuels.
The three R's for nutrient preservation are to reduce the amount of water used in cooking, reduce the cooking time and reduce the surface area of the food that is exposed. Waterless cooking, pressure cooking, steaming, stir-frying and microwaving are least destructive of nutrients. Frozen vegetables can be steamed.
Refrigeration and Freezing. Refrigeration and freezing are probably the most popular forms of food preservation in use today. In the case of refrigeration, the idea is to slow bacterial action to a crawl so that it takes food much longer (perhaps a week or two, rather than half a day) to spoil.n the case of freezing, the idea is to stop bacterial action altogether. Frozen bacteria are completely inactive. Refrigeration and freezing are used on almost all foods: meats, fruits, vegetables, beverages, etc. In general, refrigeration has no effect on a food's taste or texture.
