Glutamic Acid Residue 70% is a high-protein feed additive derived from the microbial fermentation process used in monosodium glutamate (MSG) production. Containing up to 70% protein, it serves as an efficient and sustainable Animal Feed Ingredient that provides a rich supply of single-cell protein and mycoprotein. With its high digestibility, balanced amino acid profile, and excellent palatability, this product supports efficient feed conversion and promotes healthy growth in poultry, livestock, and aquaculture. Its non-GMO origin, stable composition, and cost efficiency make it an ideal protein alternative for feed manufacturers seeking reliable quality and long-term sustainability.
Glutamic Acid Residue 70%, also known as Single Cell Protein 70%, MSG By-product 70%, or Mycoprotein 70%, is a nutrient-dense material obtained during the fermentation and extraction process of monosodium glutamate. Produced from corn or other starch-based raw materials through microbial fermentation, it represents a clean, renewable, and eco-friendly protein source widely recognized in modern feed nutrition. This fermentation-derived product contains high levels of soluble protein, free amino acids, peptides, vitamins, and trace minerals, making it a versatile ingredient in feed formulations for poultry, swine, cattle, and aquaculture.
The composition of Glutamic Acid Residue 70% features balanced amino acids, including glutamic acid, lysine, leucine, and valine, which support tissue development and enhance nutrient metabolism in animals. The protein is mainly in the form of mycoprotein and peptides, ensuring high digestibility and quick absorption. In addition, the low fiber and moderate ash content make it particularly suitable for intensive feeding programs that require both energy and nutrient density.

Feed Application and Nutritional Functions:
In poultry feed, Glutamic Acid Residue 70% enhances growth performance and feed conversion efficiency. It provides essential amino acids that support muscle development, feather quality, and immune response. The high digestibility ensures that nutrients are efficiently absorbed, minimizing waste and improving overall productivity.
For swine feed, it acts as a high-quality Animal Feed Protein Source, promoting healthy gut development and improving nutrient utilization. The product’s balanced amino acid profile supports rapid growth in piglets and improves carcass quality in finishing pigs. It also helps to reduce dependence on expensive protein ingredients such as fishmeal and soybean meal, lowering overall feed formulation costs.
In ruminant diets, Feed Grade Glutamic Acid Residue 70% contributes to improved rumen microbial activity and fiber digestion. The soluble nitrogen and amino acid content help maintain optimal rumen balance, leading to increased milk yield, weight gain, and better feed efficiency in dairy and beef cattle.
In aquaculture feed, it functions as a natural attractant and digestible protein source for fish and shrimp. The small molecular peptides and free amino acids improve palatability and feeding behavior, ensuring high feed intake and growth performance even under stressful environmental conditions.
