Claims
- 1. A process for producing enzyme-containing starch granules, comprising
- (a) contacting a starch or modified starch core selected from the group consisting of cassava starch, sago-palm starch, rice starch, wheat starch, sorghum starch, barley starch and mixtures thereof with an aqueous enzyme solution or dispersion for sufficient time to result in absorption of the enzyme solution or dispersion into the starch core without agglomeration or disintegration of the starch core; followed by
- (b) drying the enzyme-containing starch granule wherein said granule has a ratio between the largest granule and the smallest diameter of less than 3.
- 2. The process of claim 1, wherein the starch core is intrinsically capable of absorbing at least 5% w/w of water.
- 3. The process of claim 1, wherein the starch core is intrinsically capable of absorbing at least 20% w/w of water.
- 4. The process of claim 1, wherein the starch core is intrinsically capable of absorbing at least 30% w/w of water.
- 5. The process of claim 1, wherein the ratio between the largest and the smallest diameter of the granule is less than 1.5.
- 6. The process of claim 1, wherein the ratio between the largest and the smallest diameter of the granule is equal to or less than 1.2.
- 7. The process of claim 1, wherein the starch is gelatinized in a degree range of 2-95%.
- 8. The process of claim 7, wherein the degree of starch gelatinization is at least 2%.
- 9. The process of claim 7, wherein the degree of starch gelatinization is in the range of 10-60%.
- 10. The process of claim 7, wherein the degree of starch gelatinization is in the range of 30-60%.
- 11. The process of claim 7, wherein the degree of starch gelatinization is up to 95%.
- 12. The process of claim 1, further comprising adding one or more coating layers to the dried enzyme-containing starch granule.
- 13. The process of claim 12, comprising two or more coating layers.
- 14. The process of claim 1, wherein the enzyme-containing starch granule has a size in the range of about 50-4000 .mu.m.
- 15. The process of claim 14, wherein the size is in the range of 300-2000 .mu.m.
- 16. The process of claim 1, wherein the starch core further comprises one or more materials selected from the group consisting of binders, fillers, plasticizers, fibrous materials and superabsorbents.
- 17. The process of claim 1, wherein the aqueous enzyme solution or dispersion comprises one or more enzymes selected from the group consisting of peptidases, amylases, lipases, cellulases, oxidoreductases, phytases, and xylanases.
