鲜牛奶vs复原乳，该如何正确选择？

Core Viewpoint - The article discusses the differences between fresh milk and reconstituted milk, highlighting their production processes, nutritional content, and consumer choices [1][2]. Production Process - Fresh milk is directly obtained from farms and undergoes low-temperature pasteurization (72-85°C), preserving active components like whey protein and immunoglobulin [1]. - Reconstituted milk involves drying fresh milk into powder and then rehydrating it, which is a more complex process [1]. Nutritional Content - Both fresh milk and reconstituted milk retain essential nutrients like calcium and protein well, but reconstituted milk may lose some heat-sensitive vitamins due to high-temperature processing [1]. - Despite the potential loss of vitamins, dairy products are not primary sources of these nutrients, and they can be compensated by consuming vegetables, legumes, and nuts [1]. Consumer Tips - When purchasing reconstituted milk, consumers should look for the "reconstituted milk" label and prefer well-known brands for better nutritional assurance [1]. - It is advisable to read the ingredient list to understand the proportion of reconstituted milk and any additional ingredients, as well as to choose products with higher protein content [1][2]. - Consider personal needs and usage scenarios when selecting reconstituted milk, such as opting for low-sugar options for those monitoring sugar intake [2].
