does heating up milk destroy protein?
Milk is a naturally occurring liquid produced by female mammals to feed their young. It is a complex substance composed of water, proteins, fats, carbohydrates, and vitamins and minerals. When milk is heated, the proteins in the milk denature, which means they undergo a change in their structure. This change is irreversible. Denatured proteins are less soluble in water than native proteins, so they are more likely to clump together and form aggregates. This is why milk that has been heated often has a thicker consistency than milk that has not been heated. The denaturation of proteins also affects the nutritional value of milk. Some of the amino acids that make up proteins are more sensitive to heat than others, and so some of the essential amino acids in milk may be lost during heating. Additionally, the denaturation of proteins can make it more difficult for the body to digest and absorb the nutrients in milk.
does caffeine destroy vitamin d?
