Sichuan Mianzhu Pengfa Biochemical Co., Ltd. was established on 12 July 2002 and is located beside the Mianyuan River Bridge in Fuxin Town, Mianzhu City, Sichuan Province, covering an area of 30 mu in the industrial heartland of Sichuan with convenient transport and a complete industrial support system. Focused on the research, development, production and sales of amino acid series products for more than twenty years, the company advances with innovation as its sail and quality as its helm. Starting from the processing of animal and plant extracts, it has gradually concentrated on the specialized production of amino acids and has now formed a large-scale, standardized industrial layout, becoming one of the benchmark enterprises in the regional biochemical industry.
The company operates in pharmaceuticals, feed additives and bio-fertilizers, and has built a diversified product line covering three major categories: high-end amino acid monomers, compound amino acid products and amino acid chelates. Its core products include production bases for L-cystine, L-tyrosine and L-leucine, together with a large-scale production system with an annual capacity of 7,000 tons of compound amino acid powder; the range also covers functional fertilizers such as amino acid chelated manganese, copper and magnesium. Annual output of L-cystine exceeds 300 tons, L-tyrosine over 150 tons and L-leucine over 200 tons, and the company has served more than 1,000 customers.
Selecting both animal and plant sources as raw materials, the company relies on three core processes—hydrochloric acid hydrolysis, sulphuric acid hydrolysis and enzymatic hydrolysis—together with hydrolysis-purification and fine-refining technology. The resulting amino acid monomers meet pharmacopoeia standards for purity, with strictly controlled heavy metals and impurities, satisfying the admission requirements for pharmaceutical raw materials. Products conform to raw-material production standards with complete testing indicators and stable, traceable quality, meeting the batch-purchase needs of formulation production, nutritional preparations and medical products.
The company supplies single high-purity amino acid raw materials and compound amino acid raw materials, and supports formula customization, ratio development and personalized customization for fertilizers, pharmaceutical intermediates, APIs, food, daily chemicals and sports nutrition. It has passed ISO9001 quality management, ISO14001 environmental management and ISO45001 occupational health and safety management system certifications, and has been recognized as a High-Tech Enterprise and a “Specialized, Refined, Distinctive and Innovative” enterprise; it also holds OMRI, REACH, HALAL and Star-KOSHER certifications and several fertilizer registration certificates, with products sold at home and abroad.
