(一) 立项依据与研究内容（4000-8000字） 1. 项目的立项依据（附主要的参考文献目录） 现代药品大多是热敏性药品，即对温度(主要是高温)比较敏感的药品，如脂质体 （liposome）、干扰素(interferon)、组织型纤维蛋白溶酶原激活剂(tissue type plasminogen activator)、白细胞介素(interleukin)、生长激素(human growth hormone)等，还有我国的 中草药。在生产热敏性药品时，为防止由于温度过高而使药品变性，影响产品的质量， 目前广泛应用的技术是真空冷冻干燥技术(freeze-drying，lyophilization)

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

The primary concern of chilled food manufacturers is to produce a product that is both wholesome, i.e. it has all the fresh, quality attributes associated with a chilled food, and safe, i.e. free from pathogenic microorganisms and chemical and foreign body contamination. This is particularly important in this product ector as, due to the nature and method of production, many chilled foods are classified as high-risk products

Quality is an essential feature that will lead the consumer to select or not any food product. With numerous food scares that have hit the food market in the UK and Europe (E. coli, BSE, genetically modified organisms-based products, dioxins in animal feed in Belgium)consumers have become much more aware

As the chilled foods market has expanded and become more competitive, so have the demands for diversity, quality and longer shelf-life. Meeting these demands in a responsible, safe and cost-effective manner requires the application of an understanding of the factors that affect product safety and quality. Many problems can be avoided by applying this knowledge to a formalised HACCP approach to identify critical control points relating to quality
