New Study Confirms Low Carb Value of Tagatose; Finds Spherix's Sweetener Has a Glycemic and Insulin Response of 3 Percent

BELTSVILLE, Md., March 26 -- Spherix Incorporated (NASDAQ:SPEX) , today announced that a new study by a prestigious Australian University confirms the low carb value of Gaio(R) tagatose.

Gaio(R) tagatose was tested in a research study by Sydney University's Glycaemic Index Research Service (SUGiRS). The University states that, compared to glucose, which had glycaemic and insulinaemic responses of 100%, Gaio(R) tagatose produced very low glycaemic and insulinaemic responses of only 3%.

Dr. Gilbert V. Levin, Spherix Executive Officer for Science, said "It's very comforting to have a major university confirm these important inherent properties of tagatose. Together with its winning taste, this clearly differentiates our product from many others attempting to capitalize on the rapidly expanding low-carb, low-cal market. These results, well below that of competing sweeteners, may make foods and beverages with tagatose even more attractive to a weight-conscious public that increasingly embraces lowering carbohydrates to lose weight." Tagatose is a natural low-calorie sweetener patented by Spherix Incorporated. It is being manufactured and sold as Gaio(R) tagatose for food and beverage uses under license by Arla Foods Ingredients. Tagatose tastes and acts like table sugar, and can be used to sweeten foods and beverages either by itself or in combination with high intensity, synthetic sweeteners.

Tagatose is now being used in 7-Eleven's Diet Pepsi Slurpee(R), and in Pasco Brands' Light and Tasty frozen juices distributed in major chain stores and directed at the burgeoning low-calorie, low-carb market. Arla officials say they expect a range of new products using tagatose to reach the market in 2004. For more information on Gaio(R) tagatose, see Arla's website at
