DAIRY AND PLANT PROTEIN RANGE
Protein Ingredients
This range covers dairy and plant protein ingredients supplied for plant-based and high-protein nutrition. Each grade is defined by protein content on a stated basis, process route and the physical behaviour that controls dispersion in formulation.

|---|---|
| Material class | Dairy proteins, colostrum powders and plant protein flours, concentrates and isolates |
| Protein basis | Stated as-is or on a dry basis, per grade |

How to choose within this range
| Your requirement | Specification to fix | Why |
|---|---|---|
| High protein per serving | Choose isolate or high-concentrate grades | Protein content per gram determines formulation economics |
| Neutral flavour | Fix the process route and source | Flour and concentrate grades carry more off-notes than isolates |
| Allergen labelling | Fix the source and obtain a declaration | Dairy, soy and nut sources trigger different labelling duties |
| Comparing quotations | Compare protein on the same basis | As-is and dry-basis figures look different but may be the same grade |

Frequently Asked Questions
Is protein declared as-is or on a dry basis?
Both conventions exist. The basis is stated on each product page, and quotations should always be compared on the same basis.
What is the difference between a concentrate and an isolate?
An isolate is further purified and carries a higher protein content with fewer non-protein solids; a concentrate retains more of the original matrix.
Do you supply both dairy and plant proteins?
Yes. The range covers whey and milk fractions together with soy, corn, hemp, walnut, rice and other plant protein sources.
Which allergen declarations are available?
Allergen and origin declarations are issued against the specific product and destination market. State the destination when requesting a quotation.
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.
