中文摘要:

      随着越来越多的特殊食品进入大众的视野, 无论从市场监管角度还是饮食安全角度, 食品渗透压的检测和控制都具有重要的意义。但目前国内外学者对特殊食品中渗透压的研究关注度较低, 我国尚未完善特殊食品中渗透压相关标准的制定。渗透压仪分为冰点渗透压仪和露点渗透压仪, 调研显示现有的仪器完全能满足婴幼儿配方食品渗透压的测定, 但是对于基质复杂、样品状态多变的特殊医学用途配方食品可能需要更多的开发研究。本文阐述了渗透压对特殊食品的意义及婴幼儿配方食品和特殊医学用途配方食品渗透压的研究现状, 并针对适用于市场上现有的特殊食品测定的渗透压仪进行介绍和比较分析, 以期为现行标准的完善、渗透压仪的选择和特殊食品的市场监管提供参考依据。

英文摘要:

      As more and more special foods entering the public's field of vision, the detection and control of food osmotic pressure is of great significance no matter from the perspective of market supervision or diet safety. However, the research on osmotic pressure in special food has been paid little attention by scholars at home and abroad, and the formulation of relevant standards for osmotic pressure in special food has not been improved in China. The osmotic pressure apparatus is divided into freezing point osmotic pressure apparatus and dew point osmotic pressure apparatus. The investigation shows that the existing instruments can completely meet the determination of the osmotic pressure of infant formula food, but for the special medical use of formula food with complex matrix and changeable sample state, more research and development may be needed. This article described the significance of osmotic pressure to special foods and the current research status of osmotic pressure in infant formula foods and formula foods for special medical purposes, and introduced and compares osmometers suitable for the measurement of special foods on the market, so as to provide a reference for the improvement of current standards, the selection of osmometers and the market supervision of special foods.
