Novel pectinase, low-molecular pectin, and food and drink which contain low-molecular pectin

摘要

A novel pectinase for degradation a pectin or pectic acid is disclosed wherein(1) the novel pectinase is an endopolygalacturonase produced from a genus Saccharomyces,(2) the optimal pH is 4.0,(3) the stable pH range is 4.0 to 8.0,(4) the optimal temperature is 45°C,(5) the enzymatic activity is stable up to 45°C, and(6) the molecular weight is 38,000. A low-molecular pectin having a low viscosity and a high solubility and maintaining the physiological activity as the dietary fiber, and food and drink each of which contains 0.01 to 50 wt% of the low molecular pectin are also disclosed.
