第二节原料要求与贮备 一、原料基地的建设 原料基地的建设应遵循下述原则: 1.充足的面积形成足够的产量供给加工。 2.原料基地上必须有适合的加工品种,且优质、价格合理。还应不断选育新品种,更新换代

第一节罐藏原理 一、罐头食品与微生物的关系 细菌学杀菌是指绝对无菌,而罐头食品杀菌是指商业无菌。其含义是杀死致病菌、腐败菌,并不是杀灭一切微生物。严格控制杀菌温度和时间就成为保证罐头食品质量极为重要的事情

加工食品是利用食品工业的各种加工工艺处理 新鲜食品原料而制成的产品。 加工食品已丧失了生理机能,它之所以耐保藏 是因为有与新鲜原料截然不同的理论作为基础。 食品加工的根本任务就是使食品原料通过各种 加工工艺处理达到长期保存,经久不坏,随时取用的 目的。 食品加工原理是在充分认识食品败坏原因的基 础上建立起来的

第一节植物性食品原料 一、果蔬加工原料 (一)果蔬的组织结构及种类 (二)果蔬的化学成分与加工的关系 1.水分 2.碳水化合物

干制品—原料经预处理后,采用干燥或脱 水的方法而得到的产品。 干制品具一定的色、香、味、形,可溶性固 形物达75%以上,按干物质计算达80%左右, 而且加水后要能复原

Milk has been the subject of scientific study for about 150 years and consequently, is probably the best characterized, in chemical terms, of our major foods. It is probably also the most complicated and serves as the raw material for a very large and diverse family of food products. Dairy science

Milk is a dilute emulsion consisting of an oil/fat dispersed phase and an aqueous colloidal continuous phase. The physical properties of milk are similar to those of water but are modified by the presence of various solutes (proteins, lactose and salts) in the continuous phase and by the degree of dispersion of the emulsified and colloidal components
