"4.1.2 Food additives and food nutrient fortifiers", "4.3.1 Net content", "4.4 Hygiene indicators", "4.6 Addition amount of food additives and food nutrient fortifiers" and "6.1 Label" in this standard are mandatory provisions; the remaining provisions are recommended provisions. This standard is a revised standard of GB/T2746--1985 "Yogurt". The main revisions are as follows: 1 Cancelled: the indicators of sugar and mercury, the upper limit of the acidity indicator, and the regulations on product storage time. 2 Adjusted the fat indicator; changed "whole milk solids" to "non-fat milk solids", and adjusted the indicators. 3 Added: product classification, negative deviation allowable value of net content, protein, nitrate, nitrite, benzoic acid, sorbic acid, aflatoxin M, lactic acid bacteria indicators, and regulations on adding food additives and food nutrient fortifiers. From the date of implementation, this standard will also replace GB/T2746-1985 "Yogurt". This standard was proposed by the State Bureau of Light Industry.
This standard is under the jurisdiction of the National Dairy Standardization Center. This standard was drafted by the Heilongjiang Dairy Industry Research Institute; Shanghai Danone Yoghurt Co., Ltd., Guangzhou Danone Yoghurt Co., Ltd., and Inter Nutrition Dairy Co., Ltd. participated in the drafting.
