Description

A kind of carbonated drink containing isolated whey protein and its preparation process

technical field

The invention relates to the technical field of carbonated beverages, in particular to a carbonated beverage containing isolated whey protein and a preparation process thereof.

Background technique

Since ordinary protein will denature and precipitate when it encounters acidic solution, there are fewer modulated acidic protein drinks on the market. After continuous experiments and explorations, it was found that phosphorylated whey protein has good solubility in a strong acidic solution. Moreover, whey protein has excellent nutritional value, soft flavor, easy digestion and unique functionality, and has the functions of improving immunity, anti-oxidation, relieving fatigue, enhancing muscle exercise ability, and strengthening bones.

Therefore, whey protein is very suitable as the first choice ingredient of ready-to-drink protein drinks, but now whey protein is mainly used as a protein supplement raw material, or similar to other proteins, most of them are added to some neutral drinks. The type is relatively single, and people's recognition of it Know less. Carbonated drinks are popular among young people, but they are criticized for their high sugar and low nutrients.

Therefore, whey protein is added to carbonated beverages to form a compound drink with high nutritional value and good taste, which can meet the current consumer demand for beverage products with high nutrition and high taste. It has good foamability, which makes the foaming process serious and difficult to mix with carbonated water. Therefore, there is no carbonated beverage with whey protein added in the market.

The present invention aims at the above-mentioned problems, through in-depth research on the raw materials and formula of the compound drink of separating whey protein and carbonated beverage, and improving its preparation process, through the bottom high-speed shearing and premixing with other particles, the separated While the whey protein is fully dissolved, there will not be too many air bubbles, so that the whey protein isolate and carbonated water are well integrated, improving the taste and ensuring the original nutritional value of the whey protein isolate.

Whey protein isolate powder is usually added to neutral beverages or solid beverages, so that the protein beverages produced lack the stimulation of carbonic acid. In the present invention, adding it to acidic carbonated beverages can better stimulate the flavor of protein. Adds to the overall taste of protein drinks.

Whey protein isolate is known as the king of protein. It is a protein extracted from milk. It has the characteristics of high nutritional value, easy digestion and absorption, and contains a variety of active ingredients. It not only has essential amino acids with a tissue model similar to that of the human body, but also Containing extremely rich branched-chain amino acids and biologically active substances, it can effectively strengthen the body's immunity and antioxidant capacity, thereby achieving the purpose of synthesizing skeletal muscle protein and inhibiting muscle protein breakdown.

The carbonated drink containing isolated whey protein of the present invention has zero added sugar and no lactose, and is suitable for drinking by all people who want to supplement protein. Moreover, this method combines the front-stage UHT sterilization process with the post-stage pasteurization process to preserve the flavor of the product to the greatest extent while minimizing the risk of microorganisms.
