Pea protein powder is an emerging new source of protein. Pea isolate supplement is made by extracting protein from yellow peas and is typically used as a supplement to increase the protein content in veggie burgers, energy bars, and smoothies and shakes. Pea protein is a high-quality protein and is used many special diets since it’s naturally vegan and hypoallergenic. Pea protein is a high-quality protein and a great source of iron.
One of the key process components for hydrolyzation of a pea isolate slurry is a Jet Cooker. A jet cooker can provide the correct amount of shear to the slurry and ensure precise slurry heating temperatures.
Research conducted at the University of Idaho & Washington State University identified the following results when using steam injection heating and a Jet Cooker for pea isolate slurry processing:
- Direct steam injection (DSI) processing improved functional properties of pea-rice protein isolate.
- Temperature and pH of DSI treatment had significant impacts on the functionality of protein blends.
Direct steam injection (DSI) processing with pH adjustment was investigated to enhance the functionality of pea-rice protein isolate blends (PR). Protein slurries at concentration of 5% (w/w) of commercial pea and rice protein isolates in the ratio of 2:1 (w/w) across a range of steam temperatures (66–107 °C) and pH values (2 −1 1) were studied. After DSI treatment, the PR were freeze-dried to obtain the final dry protein powder. Based on protein solubility profiles, the optimal DSI processing conditions were 107 °C and pH 11. Available lysine was not reduced (P > 0.05) in the blend. Solubility (from 3 to 41%, at pH 7), emulsifying activity index (from 5.9 to 52.5 m2/g), foam stability (from 68.2 to 82.8%), and oil holding capacity (from 1.8 to 4.9 g/g) values increased (P < 0.05) compared to the untreated PR. DSI can modify the functionality of PR without affecting the essential amino acid composition. 1
