At McKenzie's we continue a family tradition of supplying generations of Australians with high quality food products. From humble beginnings as a Melbourne grain store in 1852, the McKenzie's of today has grown and evolved into one of the oldest Australian family owned and operated food manufacturers. McKenzie's Bi-Carb is a natural food grade product that does not use any aluminium-based additives in the processing of the product. McKenzie's Bi-Carb soda can be used every day in so many ways! - For your home - For your family - For your body
