B.C. firm develops new soy protein ingredient

Vancouver research and development company Burcon NutraScience has isolated a new soy protein for use in the food and beverage market.

The new isolate, which the company has dubbed Clarisoy, is 100 per cent soluble and is transparent in acidic solutions, allowing it to be used at pH down to 2.5, Burcon said in a release Tuesday.

Clarisoy “also has exceptional flavour characteristics and is heat stable, permitting hot fill applications,” the company said.

The product “shows great promise for use in a variety of healthy and great-tasting food and beverage applications and is expected to be price-competitive as well, which should be of great interest to food and beverage manufacturers currently dealing with high dairy protein prices.”

The company last month “self-affirmed” that its two other new isolates, canola proteins Puratein and Supertein, will meet “generally recognized as safe” (GRAS) food safety standards in the U.S. and has applied for approval from that country’s Food and Drug Administration (FDA).

The company aims to promote plant proteins as an “inexpensive and environmentally sound source of functional and nutritious food ingredients,” beyond their use as an “indirect” protein source in food and livestock feed.

“Today, plant proteins can be grown, isolated and purified, converting them to high-value food ingredients for human consumption at a fraction of the environmental and economic cost of animal proteins,” the company said.

“Our new Clarisoy soy protein isolate product and the associated extraction technology offer another major platform for Burcon to earn revenue and to pursue future opportunities,” said Burcon president Johann Tergesen in the release. The company said it will also seek U.S. patent protection for both the product and the technology used to isolate it.
