Description
Technical Field
The invention relates to the technical field of foods, in particular to a cream substitute and application thereof in foods.
Background
Butter (Cream) refers to a dairy product prepared by subjecting milk to centrifugal separation to obtain Cream, and ripening, stirring and pressing. The main component is milk fat, is rich in nutrition, and can be directly used or used for processing various foods, in particular various cakes, such as birthday cakes and the like. However, as the living standard of people increases, the association of high fatty saturated fatty acid content in cream with obesity and cardiovascular and cerebrovascular diseases is becoming more and more interesting, so that more healthy cream substitutes need to be developed.
Whey is a liquid that is separated from cow's milk when cheese is produced, typically 10kg of whey is obtained per 1kg of cheese produced. Whey protein contains about 48% of beta-lactoglobulin, 19% of alpha-lactalbumin, 8% of immunoglobulin, 5% of serum albumin and 20% of peptone, and also contains small amounts of lactoferrin, lactoperoxidase and the like. Whey proteins have a high nutritional value, must have a higher amino acid content than other edible proteins, and are substantially free of fat. In addition, whey protein also has excellent processing properties such as solubility, dispersibility, emulsifiability, gelation, water holding capacity, etc. However, when a cream substitute prepared from whey protein is used as a raw material, it is required to be pulverized to 10 μm or less in order to obtain a better taste, which greatly increases the production cost, and further, it is required to perform a heat treatment to form a gel, but the heat treatment is accompanied by deterioration of the nutritional characteristics of whey protein, which is difficult to form a gel without heating, and the basic processability such as hardness, viscosity, etc. is difficult to meet the relevant requirements even if the heat treatment is performed and an emulsifier is added.
Biological cellulose, also known as bacterial cellulose (BC, bacterial Cellulose), is a linear polysaccharide formed by the linkage of glucopyranose with β -1, 4-glycosidic bonds, often produced by fermentation of bacteria. It has many excellent properties such as high water holding capacity and purity, compared to plant cellulose. At present, the coconut (nata de coco) is often prepared in the food field and is widely used in dairy products, cans and other foods.
