Use | Use thickener, sweetener. High quality protein nutrient source; High solubility, which is beneficial to the appearance and organization of the product. In combination with water, resulting in viscosity; Gelation; Emulsification; Habituation, foaming and aeration; Increased flavor. Whey products have the above natural, nutritional, economic and multi-functional properties, has become a new favorite in the field of food development and application. It is widely used in food industry, such as infant nutrition food, baking, beverage and other dairy products, frozen food, candy, meat products, soup and so on. |
introduction
Whey is the solution left by the extraction of casein from the milk to make dry bribe or casein. Its main ingredients are lactose, whey protein, minerals, etc., which have high nutritional value. Whey powder is white powder, has a frankincense fragrance, soluble in water, widely used in dairy products, baked food, health food, beverages, feed products.
whey powder classification
whey powder is divided into sweet whey powder and sour whey powder according to different sources.
It is divided into salted whey powder and desalted whey powder according to whether desalted or not.
According to the degree of protein separation, it can be divided into high, medium and low protein whey powder.
In the United States, whey products can be summarized as:
①, sweet whey powder products: low, medium and high protein whey powder.
Low-protein whey powder (dialysis whey powder)-refers to a high-lactose product after extracting part of the protein from fresh whey that has never been added with any preservatives; after pasteurization and drying, the protein content is obtained It is 2.0-4.0%
Uses: It is used in feed formulations to provide high content of lactose, as an energy source for young animals, and can also promote the synthesis of lactic acid, and provide a variety of amino acids and trace elements to improve feed texture and taste. In the food industry, it can be used as a source of lactose supplement
High-protein whey powder-refers to fresh whey without any preservatives. After pasteurization and drying, the protein content is 11.0-14.5%
Use: Used as an economical source of milk solids in dairy, frozen food, baking, snack food, candy and other foods. Strengthen the formation of color in high-temperature cooking and baking; as a substitute for high-temperature milk powder, it plays an important role in high-quality bread bulking.
②, modified whey powder products: including low lactose whey powder, desalted whey powder
③ whey protein products: whey protein concentrate (WPC) and whey protein isolate (WPI)
Whey Protein Concentrate Products (WPC) Series
whey concentrated protein products (WPC) series usually have more than WPC-34, 50, 60, 75 and 80 kinds. numbers represent the lowest protein content in the products, and the physical and chemical indexes of WPC-34 products are very close to skimmed milk powder.
Whey Protein Isolate (WPI)
whey protein isolate refers specifically to whey protein products with protein content not less than 90%.
identification method
perceptually, normal whey powder is white to light yellow in color and has a milk flavor.
if it is bleached during processing, the product is milky white. if it is not bleached, the color will vary from white to light yellow. this is due to the difference in whey color obtained from different varieties of cheese.
method: dissolve a small amount of whey powder in water and let it stand.
Name Solution Appearance Odor
low protein whey powder is clear, fluorescent yellow-green, occasionally with typical whey taste of lactose precipitation, and milk aroma
high protein whey powder is layered, the upper layer is clarified liquid; the lower layer is flocculent precipitation with typical whey taste and milk fragrance
Note: Whey is fluorescent yellow-green because of the presence of water-soluble riboflavin.
Preparation method
whey is a liquid obtained by separating curd blocks when raw milk is used as raw material to produce cheese, casein and other similar products by rennet, acidification or membrane filtration. Whey powder is a powdered product made of whey as raw material and dried. Desalted whey powder, as a high-quality whey product, is especially suitable for the growth and development needs of infants and young children. It is mainly used in the production of infant formula powder and is the main auxiliary material of infant formula milk powder.
how to use
in use, the feed factory uses whey powder and other raw materials and additives to form concentrated feed or full-price suckling pig feed; The pig farm can add 10% ~ 15% of whey powder to the concentrated feed to form full-price feed, or it can be directly used with suckling pig feed containing more than 20% of whey powder.
Whey powder (E 300) is a food additive, also known as antioxidant Vitamin C. It is commonly used as an antioxidant in food processing to prevent oxidation reactions and food spoilage. Whey powder (E 300) can also help maintain the color and nutritional value of food and prolong its shelf life. In the food industry, whey powder (E 300) is widely used in juices, jams, pickled foods, and meat products. It is considered a safe food additive that meets food safety standards.
Properties: Whey powder (E 300) is a white to slightly yellow powder that is easily soluble in water. It has antioxidant properties, which help prevent oxidation reactions in food and extend the shelf life of food products.
Uses: Whey powder (E 300) is commonly used as an antioxidant in food processing, and it can be found in juices, jams, pickled foods, meat products, and other food items. It helps maintain the color, texture, and nutritional value of food products, as well as extending their shelf life.
Production: Whey powder (E 300) is typically extracted from soybeans, tomatoes, or other plants, and can also be produced through chemical synthesis. The production process involves various processing steps, including drying and grinding to obtain the final product.
Safety: Whey powder (E 300) is widely used in food and has been approved as a safe food additive. It is considered safe for consumption within recommended limits and is not known to pose any harm to human health, according to the standards set by the World Health Organization. However, some individuals may be allergic or intolerant to whey powder (E 300), so it's important to be mindful of consumption levels and individual tolerance when consuming food products containing this additive.
