一、概述家用电冰箱是日常家庭生活中的主要制冷器械。它的功能是将食品贮存于低温环境中,使其在较长时间内能抑制各种微生物在食品中的繁殖,以延长食品保鲜时间,保持原有组织和营养价值。鱼、肉、禽、蛋、乳脂品、蔬菜和瓜果等各种食品,一般由蛋白质,脂肪、碳水化合物等有机物质所组成。在常温条件下,食品给各种霉菌、细菌的繁殖提供了有利条件。尤其是在20℃～50℃的范围内繁殖更快,致使食品中的有机物质迅速分解破坏,造成食品变质腐败而不能食用。在低温冷藏条件下,大大抑制食品组织中的酵母作用,阻碍微生物的繁殖,延
First, an overview Household refrigerator is the main refrigeration equipment in daily family life. Its function is to store the food in the low temperature environment so that it can inhibit the multiplication of various microorganisms in the food for a long time in order to prolong the preservation time of the food and maintain the original organization and nutritional value. Fish, meat, poultry, eggs, milk products, vegetables and fruits and other foods, usually by the protein, fat, carbohydrates and other organic substances. Under normal temperature conditions, the food provides favorable conditions for various molds and bacteria. Especially in the range of 20 ℃ ~ 50 ℃ breed faster, resulting in rapid decomposition of organic matter in food damage, resulting in deterioration of food spoilage and can not eat. Under the conditions of low temperature refrigeration, greatly inhibit the role of yeast in food organizations, hinder the reproduction of microorganisms, delay
