Description

Methionine-Rich 2S Protein, Helianthus is a specialized plant-derived protein isolate, primarily sourced from sunflower seeds, characterized by its high concentration of the essential sulfur-containing amino acid methionine. This unique amino acid profile makes it a valuable functional ingredient for enhancing the nutritional quality of protein blends and finished products. It is particularly sought after by manufacturers in the animal feed, human nutrition, and biotechnology sectors seeking to optimize amino acid delivery and support metabolic functions.

Application

• Animal Feed & Aquaculture Nutrition: As a premium methionine supplement to balance amino acid profiles in poultry, swine, and aquaculture diets, supporting growth, feathering, and overall health.
• Human Nutritional Supplements: Incorporated into protein powders, meal replacements, and clinical nutrition products to boost methionine content and improve Protein Efficiency Ratio (PER).
• Food & Beverage Fortification: Used to enrich cereals, bars, and specialized foods targeted at populations with higher protein or specific amino acid requirements.
• Cell Culture & Fermentation Media: Serves as a defined nitrogen and amino acid source in microbial and mammalian cell culture processes for biopharmaceutical production.
• Plant-Based Product Development: Acts as a key ingredient to improve the nutritional completeness and sensory properties of meat and dairy alternatives.
• Research & Development: Utilized as a standard or experimental substrate in biochemical, nutritional, and pharmaceutical research studies.
