Main Application Fields

Feed Industry

L-Methionine is a critical limiting amino acid for livestock and poultry breeding, an essential raw material for feed mills worldwide.
Proper addition can effectively:

– Accelerate growth of swine and poultry to cut breeding costs
– Improve laying rate of hens and milk yield of dairy cows
– Optimize animal coat condition, prevent stunted growth and muscular atrophy
– Greatly improve the utilization rate of feed protein

It is widely applied in feed for pigs, chickens, cattle, sheep, aquatic products and other livestock.

Pharmaceutical Industry

As a qualified pharmaceutical amino acid raw material, it is widely used in liver-protecting formulas to assist in alleviating fatty liver, liver injury and cirrhosis. It is also adopted in compound amino acid infusion and antidote production, featuring stable safety for pharmaceutical formulation.

Food & Nutraceutical Industry

Used in compound amino acid powder and dietary supplements. It compensates the shortage of amino acids in plant protein such as grains and beans, and balances human dietary nutrition structure.

Bio-fermentation & Scientific Research

It can be used as raw material of fermentation medium and biochemical reagent, suitable for R&D production of biological laboratories and biotechnology enterprises.
