- 9. The method of claim 8, wherein the bean-based extract is based on soybeans, mug beans, black beans, or kidney beans.
- 10. The method of claim 8, wherein about 0.01 to about 3 parts by weight of the coagulant is added to about 100 parts by weight of water.
- 11. The method of claim 10, wherein the coagulant is citric acid.
- 12. The method of claim 8, wherein the supernatant is collected by filtering the suspension.
- 13. The method of claim 8, further including drying the supernatant to obtain a dried water-soluble bean-based extract.
- 14. A method of preparing a water-soluble bean-based extract comprising:
mixing about 1 to about 50 parts by weight of a pulverized crude bean-based extract with about 100 parts by weight of water; heating the mixture to between about 60° C. and about 100° C. for about 10 to about 120 minutes; adding a coagulant to the mixture to form a suspension; heating the suspension to between about 30° C. and about 100° C. for about 1 to about 120 minutes; and collecting the supernatant to obtain a water-soluble bean-based extract.
- 15. The method of claim 14, wherein the bean-based extract is based on soybeans, mug beans, black beans, or kidney beans.
- 16. A water-soluble bean-based extract prepared by the method of claim 8.
- 17. A water-soluble bean-based extract prepared by the method of claim 9.
- 18. A water-soluble bean-based extract prepared by the method of claim 10.
- 19. A water-soluble bean-based extract prepared by the method of claim 11.
- 20. A water-soluble bean-based extract prepared by the method of claim 12.
- 21. A water-soluble bean-based extract prepared by the method of claim 13.
- 22. A water-soluble bean-based extract prepared by the method of claim 14.
- 23. A water-soluble bean-based extract prepared by the method of claim 15.
- 24. A food product comprising the water-soluble bean-based extract of claim 1.
- 25. The food product of claim 24, wherein the bean-based extract is based on soybeans, mug beans, black beans, or kidney beans.
- 26. A food product comprising the water-soluble bean-based extract of claim 7.
- 27. A food product comprising the water-soluble bean-based extract of claim 16.
- 28. The food product of claim 24, wherein the food product is milk, tea, soft drink, juice, coffee, seasoning, cereal, water, beer, cookies, chewing gum, chocolate, or soup.
- 29. The food product of claim 25, wherein the food product is milk, tea, soft drink, juice, coffee, seasoning, cereal, water, beer, cookies, chewing gum, chocolate, or soup.
- 30. The food product of claim 26, wherein the food product is milk, tea, soft drink, juice, coffee, seasoning, cereal, water, beer, cookies, chewing gum, chocolate, or soup.
- 31. The food product of claim 27, wherein the food product is milk, tea, soft drink, juice, coffee, seasoning, cereal, water, beer, cookies, chewing gum, chocolate, or soup.
