Hydrolyzed collagen vs collagen peptides: what is the difference?
Hydrolyzed collagen, collagen peptides and collagen hydrolysates are commonly used terms for collagen broken down into shorter peptides. Compare the source, molecular weight and specification when selecting a grade. Undenatured type II collagen retains its native structure and is supplied to a separate specification.

Production & quality
How We Produce and Release Collagen Peptides
Every shipment is released against a batch COA. Our team supports supplier questionnaires and audits.
Raw material selection
Bovine, fish and poultry raw materials are screened for purity and safety, so protein levels stay stable from batch to batch.
Enzymatic hydrolysis
Controlled enzymatic hydrolysis breaks collagen into low-molecular-weight peptides for solubility and processing performance.
Purification
Multi-stage filtration and refining remove impurities from the peptide solution before it is dried.
Spray drying & release
Peptides are spray-dried into a consistent fine powder, then tested and packed before release.

FAQ
Collagen Peptide Sourcing Questions
Are you a collagen peptide manufacturer or a trading company?
We are a manufacturer. HydroCollix™ collagen peptides are produced at Jiangxi Hanfei Biotechnology Co., Ltd., ZXCHEM's own factory in Jiangxi Province.
What is the difference between denatured and undenatured type II collagen?
Denatured (hydrolyzed) type II collagen is broken down into peptides, like our other HydroCollix™ grades. Undenatured type II collagen keeps its native triple-helix structure and is a different ingredient with its own specification. We supply both.
Can you customize molecular weight or supply private label?
Yes. Share your target molecular weight range, packing and application, and we will confirm feasibility, sampling and pricing.
Do you hold collagen peptide stock in the USA?
Yes. Selected grades are stocked in New Jersey, Chicago and California through ZXCHEM USA for dispatch without ocean freight lead time.
What are the MOQ, packing and lead time?
For the listed bovine and fish collagen grades, standard bulk supply starts at 500 kg in 20 kg bags. China orders are ready for dispatch in approximately 14 days. Confirm the selected grade, quantity, packing, trade terms and shipment schedule in the quotation; other collagen types and customised requirements are confirmed separately.
How do I get a quotation and a free sample?
Send your company, collagen source or grade, application, required quantity in kg or MT, and destination country or port. Request the matching TDS, SDS, sample COA or a bulk quotation. Samples of up to 500 g are available for evaluation; courier cost is paid by the buyer or through the buyer's courier account.
