The fat content of lowfat milk is about half that of fresh milk, which is 1.0%~ 1.5%. Consumers are not used to low-fat, skimmed milk, mainly because after tasting skimmed milk, they think it tastes bad, like water, and it is not fragrant enough. They suspect that skimmed milk is deficient in nutrients and not as nutritious as whole milk. Ordinary milk keeps the original nutrients and fat of fresh milk after scientific disinfection and sterilization.
