Open the excellent bin and find a layer of transparent dilute water floating on the surface. Will you pour it out or stir it in? Nutrition experts point out that this layer of liquid is actually "whey protein" and is an important component of quality nutrition. There is no need to worry or waste.

Milk contains two major proteins: casein and whey protein. During the production of EQ, casein condenses into a thick body, while whey protein exists in liquid and floats to the surface at any time due to its low density. Food scientist Dr. Bryan Quoc Le described it as natural like the oil layer in natural peanut sauce and does not mean changes.

Whey protein is "complete protein" and contains nine essential amino acids that cannot be synthesized by humans. It is rich in calcium, probiotics and a variety of vitamins. Nutrition expert and author of Health Shots Aimedor said that whey protein is easy to digest and absorb, can prolong the feeling of foot, and even absorb better than casein. Therefore, when you see the liquid, you should mix it directly and evenly before eating.

Liquid separation phenomena may occur in various types of advantages, but varying degrees. Bryan pointed out that Greece has less whey due to filtering; generally, high whey content is high and the distinction is more obvious.

However, Amidor reminds that if the quality has abnormal smell, pink, yellow or green color, abnormally blocked or sticky texture, too acidic, exceeds the shelf life or the container is swelled, it may have changed. At this time, the whole box should be discarded, and do not just dig up the abnormal parts.

Experts suggest that next time you encounter a "mysterious liquid" on the surface of the quality, don't rush to pour it out. Once you suck it, you can fully enjoy its nutritional value.
