3.2. Pomegranate juices obtained from clarification with pectolitic
enzymes
The turbidity of a juice is caused mainly by the presence of
pectins and polyphenols. The methods mainly utilized to clarify

gelatine and bentonite. Various methods of
clarification were applied to pomegranate juice, mainly based on
polyphenols precipitation
