Abstract: A preblend for making lactase tablets is prepared containing about 1-99% (preferably about 200-60%) by weight lactase and about 1-99% (preferably about 40-80%) by weight microcrystalline cellulose. Lactase used in the preblend may be in combination with up to about 4 parts (preferably about 0.5-2 parts) by weight cutting agent such as sugars, starches, cellulose, and inorganic salts for each part by weight lactase. About 0.5-4% by weight lubricant such as magnesium stearate may be present in the preblend. A preferred preblend contains about 9.6 weight percent lactase and about 90 weight percent microcrystalline cellulose, or about 2000 to about 9000 FCC lactase units and from about 40 to about 80 weight percent microcrystalline cellulose. Another preferred preblend contains about 9.6 weight percent lactase, about 30.0 weight percent microcrystalline cellulose and about 59.4 weight percent mannitol. Each preblend may also contain magnesium stearate.

Abstract: There is a formulation having improved chemical stability comprising: a) from about 1% to about 20% by weight of a combination of lactase and cutting agent where said combination has from 0 to about 4 parts by weight cutting agent for each part by weight lactase; b) from about 1% to about 98% by weight of microcrystalline cellulose; c) from about 0% to about 97% by weight of mannitol; and d) an effective amount of lubricant to aid compression.
