Product Overview

L-Lysine Hydrochloride (CAS 657-27-2) is an indispensable essential amino acid that cannot be synthesized naturally by humans and animals and must be obtained from external nutritional supplementation. As the first limiting amino acid in protein synthesis, it plays a decisive role in regulating protein metabolism, promoting growth and development, and improving nutrient utilization efficiency.

It has the largest market consumption in the animal feed industry for balancing feed nutrition and improving breeding efficiency, while food-grade specifications are commonly applied in food nutritional fortification and dietary supplement formulas to supplement daily lysine intake and support human physical development and immune function. Small quantities of high-purity grades are also used in pharmaceutical amino acid infusion preparations for clinical nutritional support, forming a multi-scene and high-demand industrial and nutritional application system.

Product Characteristics

1.High-volume essential amino acid for feed and food As a mainstream feed grade amino acid and food grade amino acid, it covers the largest market demand in amino acid fortification fields.

2.Excellent stability and low hygroscopicity Compared with lysine free base, hydrochloride form features stable physical properties, easy bulk storage and long shelf life.

3.High water solubility Fast dissolution in water, suitable for large-scale feed premix production and food liquid fortification processes.

4.Multi-grade complete supply system Available in feed grade, food grade and pharma grade to meet different industrial production standards.

5.Cost-effective nutritional fortification source Provides efficient lysine supplementation at lower cost, widely recognized in global bulk nutrition industries.

Main Functions

1.Animal feed amino acid fortification Supplies essential lysine for livestock, poultry and aquatic animals, optimizes feed amino acid balance, improves growth rate and feed conversion ratio.

2.Human food nutritional enhancement Enriches lysine content in grain-based food, functional food and daily nutritional formulas, supplements essential amino acids required for human body protein synthesis.

3.Protein synthesis promotion Acts as fundamental building material for animal and human protein synthesis, supporting body development and tissue metabolism.

4.Raw material for pharmaceutical amino acid products Used in compound amino acid preparations and nutritional injection formulas for pharmaceutical industry.

5.Biochemical culture medium ingredient Serves as nutritional component for microbial fermentation and laboratory biochemical research.

Main Applications

1. Animal Feed Industry : As a classic feed grade amino acid, L-Lysine Hydrochloride is extensively added in swine feed, poultry feed, ruminant feed and aquaculture feed. It compensates for natural lysine deficiency in conventional feed ingredients, improves animal growth performance, increases breeding efficiency and reduces feeding costs. This is the largest consumption field of L-Lysine Hydrochloride globally.

2. Food & Nutritional Fortification Industry : As an important food grade amino acid, it is widely used for fortifying flour, cereals, functional beverages, compound amino acid powder and daily nutritional foods. It effectively improves the nutritional value of plant-based food and balances human daily amino acid intake, enjoying stable and large market demand in food additive industry.

3. Pharmaceutical Industry: Applied in small-batch compound amino acid oral preparations and pharmaceutical nutritional formulas for human body auxiliary nutrition supplement.

4. Biotechnology & Laboratory Research: Used as microbial culture medium raw material and biochemical research reagent for industrial fermentation and laboratory experiments.
