Description

Cereal Storage Protein 19 Kda Globulin CAS NO 146989-91-5 is a specific, low-molecular-weight storage protein fraction isolated from cereal grains. This globulin is a key functional and nutritional component, valued for its defined molecular weight and protein profile. It is essential for manufacturers in the food science, nutraceutical, and plant-based protein sectors seeking consistent, high-purity protein ingredients for product development and research applications.

Application

• Functional Food Ingredient: Used as a protein fortifier and texture modifier in nutritional bars, beverages, and meal replacements.
• Plant-Based Protein Formulations: Serves as a building block for developing meat analogs, dairy alternatives, and other vegan protein products.
• Biochemical & Nutritional Research: Acts as a reference standard or substrate in studies of cereal protein functionality, digestibility, and allergenicity.
• Sports Nutrition: Incorporated into protein powders and supplements for its amino acid profile derived from cereal sources.
• Infant & Clinical Nutrition: Potential use in specialized formulas where a defined, hypoallergenic plant protein source is required.
• Bakery & Cereal Product Enhancement: Improves the nutritional value and functional properties of baked goods and breakfast cereals.
