Pulses

Chickpea Protein

Chickpea protein is available as less-fractionated flour and more processed concentrates or isolates for human-food formulations. Compare protein on a consistent basis and match the ingredient’s demonstrated functional properties to the needs of the finished product.

Animal Products

Dried Mealworms

Dried mealworms are Tenebrio molitor larvae supplied whole or ground into meal and powder for animal-feed applications. Choose the form to fit receiving and mixing needs, and compare nutrient analysis on a consistent basis because processing and test methods affect reported composition.

Different protein ingredients serve different purposes

This collection spans dairy proteins, plant proteins and an animal-origin meal. They are not interchangeable just because each is described as a protein ingredient: source, processing, intended use and applicable specifications differ. The listed examples are instant whey protein isolate 90, milk protein concentrate 70/80/85, soy protein isolate, rice protein and lamb meal.

Milk protein concentrate contains both casein and whey proteins, while whey protein isolate is whey-derived. MPC grade numbers indicate protein levels, but the number alone does not define a complete specification. Soy and rice proteins are plant-derived ingredients; lamb meal belongs to a separate animal-food context and should be assessed using appropriate feed-ingredient documentation.

Read protein claims in context

A protein percentage is only useful when its analytical basis is clear: confirm whether it is stated as received or on a dry basis, and check the method and moisture result. For MPC, compare protein with lactose, fat and ash limits; higher-protein MPC grades generally have less lactose. Do not assume that a product name or grade number guarantees a particular lot’s composition.

Protein content also does not predict performance on its own. Solubility and dispersibility can matter in food processing, and rice protein’s limited water solubility can constrain some formulations. Ask for performance information relevant to the actual process rather than assuming two isolates behave alike.

Match documentation to the intended market

For human-food ingredients, review source and processing details, composition, relevant microbiological criteria, allergen and labeling information, and storage instructions. For lamb meal, verify the ingredient identity, applicable feed labeling basis, guaranteed analysis and relevant mineral measures. Human-food protein specifications do not establish an animal ingredient’s identity or suitability.

Before a bulk purchase, compare current lot documentation and confirm packaging, traceability and the commercial terms that affect receiving and use. Where functionality is important, evaluate the ingredient in the buyer’s own formulation and processing conditions.

Common questions.

Does “90” in instant whey protein isolate 90 confirm 90% protein as received?+

Not by itself. Check the specific specification for the protein basis, analytical method and lot result; a dry-basis figure is not the same as an as-received figure.

Is milk protein concentrate 85 equivalent to whey protein isolate?+

No. Milk protein concentrate contains both casein and whey proteins, while whey protein isolate is whey-derived. Their composition and functional behavior are distinct.

Can rice protein and soy protein isolate be substituted based on protein percentage?+

Protein percentage alone is not enough to establish a suitable substitution. Compare solubility or dispersibility and other process-relevant performance in the intended formulation.

What documentation matters when buying lamb meal in this collection?+

Verify the ingredient identity and applicable feed labeling basis, then review the lot’s guaranteed analysis and relevant mineral measures. Do not infer composition or intended-use suitability from the name alone.
