Description
Technical Field
The invention belongs to the technical field of dairy products, and particularly relates to a composition, a goat milk product and a preparation method of the goat milk product.
Background
For various reasons, many mothers often feed infants with milk formula milk powder, but because casein is high in content in milk and is an anisotropic protein, a series of milk allergy symptoms are easily caused, and therefore, the feeding mode brings great troubles to parents and infants. In recent years, with the development of goat milk industry, infant formula goat milk powder is produced at the same time, and has become a substitute term of 'hypoallergy', so that the infant formula goat milk powder is widely held by the market.
In 2012, the european union determined that goat milk protein in infant formula goat milk powder is a "comfortable" protein, and approved that goat milk protein is added to infant formula goat milk powder as a protein source. During 2010-2015, only 2% of the global infant formula milk uses goat milk, and less than 1% of the formula is added with goat milk powder or goat whey protein powder; in the area of concentration of goat milk addition, namely Asia-Pacific area, only 4% of goat milk is used, and 1% of goat milk powder is used. With the development and application of goat whey protein powder, more and more enterprises begin to produce infant formula milk powder from whole goat milk protein.
However, due to the scarcity of goat milk, the defatted goat milk powder is more deficient, and the infant goat milk powder products of various manufacturers are rarely added with the defatted goat milk powder, because the fat of the goat milk left after the fat removal is limited in use, and the productivity of the goat milk manufacturers is limited, so that the vigorous market demand cannot be met. Therefore, the global existing production of defatted goat milk powder cannot meet the rapidly growing demand of the goat milk powder market.
Based on the situation, when the pure goat milk infant formula goat milk powder is produced by domestic and foreign milk enterprises, more whole goat milk, whole goat milk powder and goat milk albumin powder have to be added as protein sources. However, the formula has more defects, such as serious mutton smell caused by full-fat goat milk and full-fat goat milk powder, poor product reconstitution caused by goat whey protein powder (easy thermal denaturation) and the like.
Therefore, the goat milk powder product which can remove the smell of the mutton and ensure good reconstitution property needs to be developed.
