BioExx develops first commercial rapeseed protein isolate

BioExx Specialty Proteins Ltd. is pleased to announce that it has successfully produced the world's first commercial-scale rapeseed protein isolate, known as Isolexx(TM).

The product was produced in the second full-scale protein run at the Saskatoon facility and was repeatedly tested in both the BioExx lab and at the independent testing facilities of POS Pilot Plant Corp.

Average indicated purity at BioExx was 95.8% and the average at POS was 94.8%, with all other characteristics being similar to or better than the product from the recent initial protein run.

The plant was also able to much more thoroughly recover the product that was produced, resulting in an exceptionally strong yield of protein isolate at over 90% of what has been forecast for long-term continuous operations. This was achieved by ensuring the batch run was operated as close to a continuous process as possible, thus avoiding the precipitate issues experienced in the first run and by controlling the operating parameters of the large spray dryer in an improved manner.

Isolexx(TM) compares favourably against other plant-based proteins, such as soy and pea protein isolates, as well as higher priced animal-based protein isolates, such as whey and caseinates.

Isolexx(TM) is tested to have high nutritional value, low allergenicity, benign flavour, and good solubility and functionality. In addition, recent trials have indicated that Isolexx(TM) has very good digestibility and is well suited, as an example, for use in nutritional and protein bars, with lower water absorption than traditional isolates (leading to extended shelf life and low bar hardening), and being functionally superior to soy and comparable to whey proteins.
