Useful Properties

Vegetable Proteins are used in foodstuffs for their functional properties (binding, emulsification, water retention…) to prolong the life of food products (emulsion stability, limitation of the development of micro-organisms, control over the product’s propensity to go stale) and act on their mouthfeel (texture, softness, reduction in loss of cooking juices..)


But Vegetable Proteins are also useful for their nutritional properties because they increase quality proteins without contributing extra associated lipids. 
 

Rediscovery of nutritional advantages

Vegetable proteins bring essential amino acids which complement other protein ingredients : meat and milk proteins etc.


The nutritional value of a food formula depends on how well its ingredients go together. For example, pulse proteins are rich in lysine and as such, complement cereal proteins, particularly wheat which is richer in sulphured amino acids (Methionine Cystine). 


Vegetable Proteins contribute balance to foods by diversifying the nutritional content as recommended by nutritionists, especially by increasing the vegetable part of our diet.
