VANCOUVER, Aug. 17 /CNW/ - Burcon NutraScience Corporation (TSX-V: BU)
announces today that it has been granted a patent by the European Patent
Office: European Patent No. 1434493 - "Flax Protein Isolate and Production" -
which covers a novel protein isolate derived from any flax oil seed, including
the low linolenic acid variety Linola(TM) oil seed, and the production
thereof.

Linola is the trademark name of solin varieties, strains of flax, now
being developed by Canada's Agricore United through a joint venture with
CSIRO - the Commonwealth Scientific and Industrial Research Organization of
Australia which developed the original strain in the early 1990's.

The patent application, which is the subject of this announcement, was
originally filed in November 2002. At that time, Burcon also filed
applications, which are currently being reviewed, with the United States
Patent and Trademark Office as well as internationally under the Patent
Cooperation Treaty of the World Intellectual Property Organization.

Burcon has committed to register this patent in some twenty European
countries.

As previously announced, Burcon already holds four U.S. patents over
canola protein processing technology and canola protein isolate product uses.
A number of Burcon's patent applications, including one which has already
granted, are applicable to oilseeds and oilseed meals other than canola;
including sunflower, soybean and even hemp seed. This is the first exclusively
non-canola based technology over which Burcon has obtained patent protection.

"Flax is an important oil seed crop which has seen strong growth in
consumer awareness for its health benefits including omega 3 fatty acids,
lignans and fibre," stated Johann F. Tergesen, Burcon's President & COO who
added, "Burcon will continue to devote some of its resources to exploring
opportunities beyond its core canola protein isolate technology."

About Burcon NutraScience

Burcon is a research and development company developing a portfolio of
composition, application, and process patents around its plant protein
extraction and purification technology. The goal of Burcon's research is to
develop its patented process to utilize inexpensive oilseed meals for the
production of purified plant proteins that exhibit valuable nutritional,
functional or nutraceutical profiles. Burcon, in conjunction with Archer
Daniels Midland, is currently focusing its efforts on developing the world's
first commercial canola proteins, Puratein(R) and Supertein(TM). Canola,
recognized for its nutritional qualities, is the second-largest oilseed crop
in the world after soybeans. Burcon's goal is to develop Puratein and
Supertein to participate with soy, dairy, and egg proteins in the expanding
multi-billion-dollar protein ingredient market, with potential uses in
prepared foods, nutritional supplements, and personal care products.
