ABSTRACT:
The present invention discusses the use of pectinesterase to demethoxylate high-methoxylated pectins. The pectinesterase makes possible the preparation of food containing fruit or vegetables in a more efficient way. Specifically, fruit and vegetable jams, jellies, compotes and soups are prepared without or with greatly reduced sugar and pectin addition. The present invention also discusses a process for producing apple sauce comprising the use of pectinesterase.
