Abstract

A debranching enzyme (pullulanese) useful in the preparation of a low calorie beer may be obtained from rice by extraction of the rice with an aqueous buffer system having a pH of about 6. A preferred buffer system is 0.1 M potassium phosphate-0.2 M-sodium chloride. Extraction is preferably carried out at a temperature of about 50.degree. C. for about 3 hours. When malted rice is used as the enzyme source a particularly useful mixture of the debranching enzyme and alpha 1,4 carbohydrases is obtained.
