Amino Acid Biostimulant Manufacturer & Supplier in China
Pepaid™ amino acid biostimulant ingredients from our own protein hydrolysis plant: animal-derived peptides and free amino acids, plant protein hydrolysates and fermentation-derived grades for fertilizer and biostimulant formulations.
Product range
Four Pepaid™ Series for Every Formulation
Choose the Pepaid™ series by source and amino acid profile: enzymatic peptides, free amino acids, plant hydrolysates or fermentation-derived amino acids. Listed chloride limits range from ≤1.5% to ≤30%; check the grade against your crop and application method.
Animal-derived enzymatic polypeptides
Pepaid™ EA Series
Enzymatically hydrolyzed animal protein with peptides in three molecular-weight ranges, from standard to ultra-low.
Avg. MW 0.5–7 kDa
Animal-derived free amino acids
Pepaid™ HA Series
Deep hydrolysis of animal protein for high free amino acid content, in powder and liquid form.
Free amino acids up to ≥ 75%
Plant protein hydrolysates
Pepaid™ EP Series
Enzymatic hydrolysates of corn and soybean protein for formulations that avoid animal-derived inputs.
Plant origin · no animal inputs
Fermentation-derived amino acids
Pepaid™ FP Series
Amino acids produced by corn fermentation, with a very high free amino acid content.
Free amino acids ≥ 90%
Values are specification limits. Exact limits, pH and solubility follow the controlled TDS of each grade.
Selection guide
Which Pepaid™ Grade for Your Program?
A starting point by application method and crop. Our team confirms the grade against your formulation and target market.
Our approach
NEO: The Pepaid™ Approach to Amino Acid Biostimulants
Twenty years of protein hydrolysis applied to crop nutrition.
New Ecology
Animal by-products, corn and soybean are the sources for this bio-based ingredient range. Confirm environmental claims against the documents for the selected grade.
New Efficiency
Controlled enzymatic hydrolysis to defined peptide sizes and free amino acid levels, so each grade fits its application.
New Origin
Made with the quality systems of our food-grade protein plant, with batch testing and full documentation.

Our factory
Hanfei: Our Amino Acid Biostimulant Factory
Jiangxi Hanfei Biotechnology Co., Ltd. is ZXCHEM Group's own protein hydrolysis factory in Shangrao, Jiangxi. Since 2005 it has run controlled enzymatic hydrolysis for collagen peptides, and applies the same technology to Pepaid™ amino acid biostimulants for fertilizer and crop nutrition formulators. Every Pepaid™ amino acid biostimulant grade is available with a TDS and a free sample.
FAQ
Amino Acid Biostimulant Sourcing Questions
What is the difference between the EA and HA series?
The EA series is enzymatically hydrolyzed animal protein that keeps most amino acids bound as peptides, in three molecular-weight ranges. The HA series is more deeply hydrolyzed, with free amino acids up to 75% or more, and includes liquid grades.
Do you have amino acids without animal-derived raw materials?
Yes. The EP series is made from corn (EP60) and soybean (EP60P) protein, and FP90 is produced by corn fermentation.
Why does chloride content matter?
Chloride-sensitive crops and drip systems need low-chloride grades such as HA20-LLC, EA80-LMW or EA80-uLMW (≤1.5%). For chloride-tolerant crops such as coconut and oil palm, HA40 and HA20L offer a lower-cost option.
What documents can you provide for registration?
We provide COA, TDS, MSDS and SGS reports. REACH pre-registration and Halal and Kosher documents are available. Tell us your target market and we will prepare the matching file set.
What is the MOQ, and can I get samples?
The MOQ is 500 kg. Samples are available for formulation and field trials, and some grades ship from US warehouse stock.
