Pea protein and pea protein hydrolysate: alternative nitrogen sources for the fermentation industry offering excellent performance

As a sustainable, non-GMO vegetable resource with no major allergen concerns, pea protein is well situated to meet growing consumer demands.  Due to wide ranging acceptance and compatibility with increasing regulatory restrictions, pea protein is rapidly gaining acceptance for use in food, beverage, probiotic, nutraceutical, and fermentation applications. 

Roquette has developed Nutralys™ S85F pea protein and Nutralys Pea HF (exp.) specifically as nitrogen sources for fermentation applications. In this presentation, we evaluated both Nutralys™ S85F and Nutralys Pea HF (exp.) with Bacillus subtilis (ATCC #21770) for cell growth and alpha-amylase production, and Saccharomyces cerevisiae for yeast propagation.  Both examples demonstrated excellent performance and potential advantages when using Nutralys Pea HF (exp.) as fermentation nitrogen source in comparison to current commercially available pea peptones, corn peptones, soy flour and Solulys.

Based on the data collected, and product characteristics that demonstrate compatibility with the food/probiotic sector, we have concluded that Nutralys Pea HF (exp.) is an excellent nitrogen source option for a wide range of fermentation applications.
