食品营养标签分析的标准物质研究

提高测量精确性可以保证食品营养标签提供食品营养可靠可知性和产品质量,是提高食品营养质量评价的重要手段。食品营养成分标准物质可保证测量有效性,是验证营养标签分析方法和实验室内分析的质量保证所必需的,对营养标签标准和标签法具有支持和推动作用。阐述了我国和美国食品营养分析标准物质,并介绍了美国AOAC作为发展一系列基于蛋白质、脂肪和碳水化合物的代表所有食品标签分析的标准物质的食品三角形模式图。

Study on Food Nutrition Labeling Analysis of Certified Reference Materials

An improved measurement accuracy can assure the accurate and reliable nutrition label informations of the food and product quality,and is the important way of well-defined quality assessment of the food and nutritional products. Food-matrix nutriment certified reference material(CRM)can assess validation of the accuracy of these measurements. It is needed to validate analytical methods and for quality assurance when assigning concentration values to in-house food analyses. Such reference materials will facilitate compliance with new nutritional labeling standards and laws. Our food-matrix CRM and American standard reference materials (SRMs) of food nutrition concentration values,as well as AOAC International prepared a nine-sectored triangle for development of a series of reference materials representing all foods in which foods are positioned based on protein, fat and carbohydrate content is described.
