Chapter13 has outlined the concept of hygienic design'and hygienic practices'in controlling the safety of chilled food products. This chapter deals with hygienic practices, specifically those related to cleaning and disinfection. Contamination in food products may arise from four main sources: the constituent raw materials, surfaces

This chapter focuses on the key elements of international and national regulatory controls and associated guidance on the manufacture, storage and distribution of chilled foods. European countries in membership of EU are covered only insofar as where national legislation or guidance exists in addition to general EU rules Since chilled foods are a relatively recent

Chilled food technology has had a very significant impact on the types of food eaten by consumers during the 1980s and 1990s. This method of food preservation has satisfied the desires of people for safe, reliable, fresh products providing convenience despite the limited shelf-life. This introduction reviews the definition, range and market size of chilled food and indicates trends for the L1 Definition Foods distributed under refrigeration and sold from refrigerator cabinets have been available for many years. Although there were many new chilled product

1.低温系统与常规空调系统的比较 低温送风空调是随着冰蓄冷技术的发展而兴起的,而冰蓄冷技术的发展是随着人们生 活水平的提高、用电峰谷差愈来愈大而发展起来的。低温冷冻水具有相对大的冷量,在输 送中可以减小管道的尺寸,减少泵的电耗。在空气处理设备中,由于低温水的送人,可减 小空气处理设备的尺寸,同样也可减少风机电动机的电耗。因此,低温送风空调愈来愈引 起人们的重视

定义:菌种的扩大培养就是把保藏 的菌种,即砂土管,冷冻干燥管中 处于休眠状态的生产菌种接入试管 斜面活化,再经过扁瓶或药瓶和种 子罐,逐级扩大培养后达到一定的 数量和质量的纯种培养过程。这些 纯种的培养物称为种子

一、红肠 1.原料的选择和粗加工 猪肉和牛肉是红肠的主要原料,羊肉、兔肉、鸡肉等畜禽肉也可以做红肠的原料。原料肉必须是健康动物 宰后的质量良好的并经卫生检疫部门检验合格的肉。原料肉最好使用新鲜肉或冷却肉,也可以使用冷冻肉, 在使用前1天解冻。原料肉使用前还必须剔骨,注意不要将碎骨混到剔好的肉中,或残留未剔净的碎骨, 更不能混入毛及其他污物
