Rapid plant protein extraction
Rapid reactive-extrusion cuts plant-protein extraction to 5–10 minutes while enhancing functionality and digestibility.
On average, plant protein-based foods are 50-300% more expensive than their animal-based counterparts. Although improvements in formulation and processing are gradually reducing the price disparity, it remains a considerable challenge, particularly for individuals unfamiliar with plant proteins and their associated products. Researchers at Purdue University have developed rapid protein extraction with improved functionality and digestibility. Traditional alkaline extraction normally requires 1-2 hr, which is time consuming and limits the production volume. This technology shortens the extraction time to 5-10 min with continuous and large-scale production. It helps food ingredient companies who want to efficiently produce plant protein ingredient with better functionality and nutrition by hydrolyzing plant proteins and increases its water and digestive enzyme accessibility unlike traditional alkaline plant protein extraction. This technology is believed to have great potential in the food industry manufacturing process.
Technology Validation:
SDS-PAGE showed the molecular weight of extracted canola proteins decreased from 20-35 kDa to 10-23 kDa after reactive extrusion, demonstrating the effectiveness of Alcalase in degrading protein during extrusion.
Advantages:
-This technology is faster, more productive and the produced ingredient has better functionality and digestibility.
Applications:
-Food Ingredient company that has plant protein as their products, such as ADM, Ingredient, Cargill, Kerry Group, etc.
