What is a vegan protein powder?
A vegan protein powder is a food supplement or sports nutrition product made from plant proteins, free of any animal source, and usually consumed mixed with water or plant milk. As an alternative to whey protein it appeals to consumers who are lactose intolerant, follow a vegan diet or have a milk allergy. The most common products on the market are based on pea protein and rice protein, while pumpkin seed protein is added for its mineral profile and for differentiation.
Choosing the protein source
Pea protein forms the backbone of the formula with its high protein content, good solubility and lysine content. Rice protein complements the sulphur amino acids and balances the profile with its neutral taste. The two are usually used together at 70:30 or 60:40 (pea:rice). Pumpkin seed protein is rich in minerals such as magnesium, zinc and iron; because of its greenish colour it is easier to use in cocoa or green products.
Calculating protein per serving
The value highlighted on the label is usually protein per serving. For example, if 20-22 g of protein is targeted in a 30 g serving, the share of the protein ingredient is calculated after allowing for flavourings, sweeteners and other ingredients. The calculation should use the as-is (not dry-basis) protein values of the ingredients, and the protein value of the final product should be verified by analysis.
Solubility and mouthfeel
The most frequent consumer complaints about vegan protein powders are lumping, sediment at the bottom of the glass and a gritty mouthfeel. Fine or micronised protein grades, wetting agents such as lecithin and low doses of thickeners such as xanthan or guar reduce these problems. Agglomerated (instantised) ingredients give a homogeneous mix within seconds in a shaker.
Taste and flavour management
The legume and cereal notes of plant proteins directly affect flavour choice. Cocoa, coffee, vanilla, hazelnut and red berry flavours are effective at balancing these notes. Stevia, sucralose or erythritol can be used as sweeteners, and a trace of salt balances taste perception. Sensory tests should be carried out with samples prepared in both water and plant milk.
Blending, filling and shelf life
Blending time should be validated for homogeneous distribution of powder ingredients and segregation checked during filling. Barrier packaging and desiccants can be considered to prevent moisture pick-up. Moisture, caking, flavour loss and microbiological values should be monitored throughout shelf life.
Ingredient sourcing notes
For protein ingredients, request a batch certificate of analysis, heavy metal report, allergen and GMO statements and, where required, organic and vegan certificates. PERDIST supplies pea protein, rice protein and pumpkin seed protein with their documents and offers samples and alternative grades for trial production.
