Description

Whey, Proteins CAS NO 91082-88-1 refers to a high-quality protein fraction derived from whey, a by-product of cheese manufacturing. This product is valued for its excellent nutritional profile, high biological value, and rich content of essential amino acids, particularly branched-chain amino acids (BCAAs). It is a critical functional ingredient for the food and beverage, sports nutrition, and pharmaceutical industries, where it enhances protein content, texture, and nutritional value.

Application

• Sports & Performance Nutrition: A primary protein source in protein powders, bars, and ready-to-drink shakes for muscle recovery and synthesis.
• Functional Food & Beverage Fortification: Used to boost the protein content and improve the nutritional quality of products like yogurts, cereals, baked goods, and meal replacements.
• Clinical & Medical Nutrition: Incorporated into enteral formulas, dietary supplements, and specialized medical foods for patients requiring high-quality, easily digestible protein.
• Infant Formula: Serves as a key protein component to mimic the nutritional profile of human breast milk.
• Healthy Aging Products: Formulated into supplements designed to combat sarcopenia (age-related muscle loss) and support overall wellness in older adults.
• Weight Management Products: Utilized for its high satiety index in shakes and snacks designed for weight control programs.
