SunOpta Expands Oat Fiber Capacity

TORONTO, Dec 16, 2003 -- SunOpta Inc. (SunOpta) (Nasdaq:STKL) (TSX:SOY) today announced that it has completed a 20% expansion of its oat fiber production capacity at its Cambridge, Minnesota facility.

The Company also announced that it has approved a further expansion of 35% to be implemented by March 1, 2004 at the Cambridge, Minnesota facility. Total cost of the first two phases is estimated at $1.2 million.

The Cambridge facility is operating on a seven day, 24 hour basis and is expanding to meet the substantial increase in the demand for oat fiber due in part to the concerns over obesity and the popularity of the Atkins and other low carbohydrate diets. Oat fiber is low in available carbohydrates plus absorbs up to seven times its weight in water, which is free of carbohydrates and when added to bakery products allows for the production of low carbohydrate breads, pastries, muffins, bagels, tacos and tortillas. Oat fiber is also used in other categories such as dairy, meat and snack food products.

The Company is currently further assessing operational capabilities at both the Cambridge and Louisville facilities in an effort to further expand production and optimize processing capabilities.
