BioExx Files Process Patent Application for Production of Unique Protein Concentrates and Protein Isolates

TORONTO, ONTARIO, May 20 (MARKET WIRE) --
Bio-Extraction Inc. (TSX VENTURE: BXI) ("BioExx") is pleased to announce
that it has filed a U.S. patent application on its unique and simplified
processes for the production of specialty canola protein products ranging
from 60% (Concentrates) to more than 90% (Isolates) protein by weight.
The development work behind the patents has been completed in tandem
between BioExx at its R&D facility in Charlottetown, PEI and with POS
Pilot Plant Corp. ("POS"), a contract R&D facility in Saskatoon,
Saskatchewan.

These developments represent a substantial escalation in the proprietary
Intellectual Property base owned by BioExx. Previously, BioExx had
intended to use commercially available separation technologies in its
protein concentrates production. However, as a result of the R&D services
supplied by POS, and the success of the ongoing R&D conducted by BioExx,
it is expected that the processes subject to the patent application will
result in higher quality and higher yields of proteins, lower production
costs, and an accelerated time to market for the high value, human food
product uses. Taken together, these factors enable greater competitive
advantage, higher barriers to entry, and improved economics in the BioExx
specialty protein business.

BioExx has previously developed a unique process that avoids negative
changes in properties of the Canola that are caused by in traditional,
high temperature oil extraction processes. This results in an "improved
starting point" to separate proteins from the meal that remains after the
oil extraction has been completed. This enabled development of the
simplified approach to protein separation described in the new patent
application. The BioExx process results in unique protein concentrates
and isolates after separation.

In tandem with this effort, BioExx has also filed Canadian trademark
applications in connection with the resulting five products.

The products are:

CONCENTREXX(TM) - a Canola Protein Concentrate, at 60% to 70% protein by
weight, for primary use in aquafeeds, swine and pet foods.

ADVANTEXX(TM) 70 - a Canola Protein Concentrate, at 70% to 75% protein by
weight, for primary use in products such as baked goods (bread, rolls,
cakes, cookies, biscuits, crackers, pancakes, pastries, donuts, pasta
products, etc.), meat products (baked meat, hot dogs, sausages, bologna,
analogs, ham, etc.), and vegetarian foods.

ADVANTEXX(TM) 80 - a Canola Protein Concentrate, at 75% to 85% protein by
weight, for primary use in products such as baked goods, meat products,
and miscellaneous applications (candies and confection, desserts, diet
items, Asian foods, soup mixes, gravies, etc.)

ISOLEXX(TM) - a high-functional Canola Protein Isolate, with 90% or
higher protein by weight, for primary use in products such as nutritional
beverages (protein fortified soft drinks, sports drinks, fruit juices,
etc.), nutritional supplements, infant formulas, meat products
(comminuted meats, emulsified meats, combination meat products, etc.),
dairy analogs and dried milk replacers, and egg replacers.

VITALEXX(TM) - a hydrolyzed Canola Protein Isolate, with 90% or higher
protein by weight, for primary use in products such as nutritional
beverages, cosmetic ingredients, and health foods.

"We see this as a watershed moment in the development of this company.
With the technical support of our research contractors such as POS and
the Feeds Innovation Institute, and a phenomenal effort on the part of
our BioExx R&D and Business Development teams, we are now in a position
to accelerate our business plan well ahead of expectations", said Chris
Carl, Chief Executive Officer of BioExx. "With the work behind these
patents being completed, we expect to significantly improve our future
profitability by migrating to higher value products sooner than
originally anticipated, while at the same time adding tremendous
additional value to our intellectual property stable. This is a great
example of the tremendous results that a strong team can produce."

BioExx will now immediately begin working toward regulatory approval of
the higher concentration protein products for use as food ingredients, a
process which is expected to take up to one year. Individual products
will be introduced and made available to customers in planned release and
production phases, from lower to higher concentrations. Samples of some
of these products are being shipped on a confidential basis to
prospective customers who are working with BioExx to tailor the products
for their end markets. Detailed product specifications and additional
product samples can be made available to customers in accordance with the
BioExx product management plan.

As a result of this development success, the design of the Saskatoon
plant is already being modified to incorporate the ability to migrate in
due course to include the production of human food use products,
including a clean room and food grade equipment specifications. The
target market for Concentrates to be produced at the opening of the
Saskatoon plant remains firmly centred on aquaculture, and it is expected
that aquaculture will always constitute a significant core component of
the production in Saskatoon and at future facilities.

About Bio-Extraction Inc.

The global demand for ever higher food value from agriculture is growing
at an unprecedented pace, driven by population growth and economic
growth. At the same time, food supply constraints are increasing, due to
urban development of arable land, alternate uses of crops for bio-fuel
and other industrial purposes, and many crops having already maximized
yields. The result is an alarming imbalance between over-demand and
under-supply.

BioExx owns patented technology which allows for much lower temperatures
to be used for the extraction of active ingredients and oils from
biomass. This makes BioExx particularly well suited to process oilseed
crops in a manner that allows for the production of much higher value
additives to the food chain, in the form of higher yields of high value
proteins which tend to be temperature sensitive. While forming just a
small, but very valuable part of the solution to prominent global
agricultural problems, BioExx has a mandate to rapidly grow the company
through the construction and operation of extraction facilities around
the world - and because of its much lower energy requirements, to do so
in a very environmentally responsible manner.
