How to choose within this range

Your requirement	Specification to fix	Why
Clear solution in beverages	Fix molecular weight and clarity	Low-molecular-weight fractions dissolve faster with less haze
Neutral taste	Specify the degree of hydrolysis	Extent of hydrolysis drives bitterness and off-notes
Species-specific claims	Fix the source declaration	Source material must match the finished-product labelling
Comparing suppliers	Compare on protein basis and MW data	Identical product names can hide very different specifications

Purchasing and delivery

Evaluation sample typically 10-20 g, subject to stock
Regular MOQ typically 1 kg
1 kg foil bag or 25 kg fibre drum with inner food-grade liner
Typical lead time 7-15 working days after deposit, subject to stock and testing

Qualification and COA review

Each peptide page cites its own source material, protein basis and representative batch. Final acceptance requires the approved specification, the current lot COA and the molecular-weight distribution data where that parameter is controlled.

Frequently Asked Questions

What is the difference between a peptide and a protein?

A peptide is a shorter chain produced by hydrolysis and behaves differently in solubility, taste and viscosity. The degree of hydrolysis drives those differences.

How is molecular weight declared?

As a distribution, typically stated as the proportion below a stated cut-off such as 1,000 or 3,000 Da. Confirm the analytical method used.

Are peptides from different species interchangeable?

Not necessarily. Source material affects the amino acid profile, declaration requirements and labelling, so it must match the finished product.

Do these peptides dissolve in water?

Low-molecular-weight fractions generally disperse and dissolve readily, but clarity and taste should always be verified in your own matrix.

Are you a manufacturer or a trading company?

We are Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer integrating R&D, production and export support. Factory review may be arranged by video or an on-site visit.

Can I request the current batch COA before ordering?

Yes. Request the applicable current or representative COA for each shortlisted grade and compare identity, method, limits and results.

What is the minimum order quantity?

The regular MOQ is typically 1 kg. Evaluation samples of 10-20 g may be arranged subject to stock.

Can specifications or packaging be customised?

Selected assay targets, particle size, carrier and packing may be reviewed case by case before quotation.
