灭菌乳不能再使用复原乳 新国标保障纯牛奶更纯正

Core Viewpoint - The new national standard for sterilized milk in China mandates that sterilized milk can only be produced using raw milk, prohibiting the use of reconstituted milk, thus ensuring a 100% fresh milk production standard for sterilized milk [1][2]. Group 1: New Standards and Regulations - The implementation of the new national standard for sterilized milk signifies a shift towards using only fresh raw milk, enhancing the purity of the product [1]. - Reconstituted milk, which is made by rehydrating milk powder, is no longer allowed in the production of sterilized milk, ensuring that products labeled as "pure milk" are genuinely made from fresh milk [1][2]. Group 2: Nutritional Comparison - Reconstituted milk undergoes two rounds of ultra-high temperature processing, resulting in significant nutrient loss, particularly of heat-sensitive vitamins such as B1, B2, and C, as well as active calcium and lactoferrin [2]. - In contrast, sterilized milk made from fresh raw milk retains more natural nutrients, enhancing its freshness and overall quality [2]. Group 3: Consumer Guidance - Consumers are advised to check the nutritional content on product packaging, ensuring that full-fat sterilized milk meets the national standards of protein content (≥2.9g/100g) and fat content (≥3.1g/100g) [3]. - Quality indicators for sterilized milk include a white or slightly yellow color with natural luster, a uniform liquid state without clumps or sediment, and a pleasant, slightly sweet taste [3].
