Claim 1
Independent Claim
35 words
A method of removing limonin from citrus fruit juice which consists of contacting the fruit juice with at least one cellulose ester adsorbent in gel or powder form in the absence of, an added enzyme.
Claim 2
Independent Claim
35 words
A method of removing limonin from citrus fruit juice which consists of contacting the fruit juice with at least one cellulose ester adsorbent in gel or powder form in the absence of, an added enzyme.
Claim 3
Dependent Claim
19 words
A method as claimed in claim 1, wherein the cellulose ester adsorbent comprises celluose acetate or cellulose acetate butyrate.
Claim 4
Dependent Claim
