METHOD FOR PRODUCING FRUIT JUICE, APPARATUS USED THEREFOR AND FRUIT JUICE OBTAINED BY THE SAME METHOD

Japanese Patent JP3903379

B2

PROBLEM TO BE SOLVED: To provide a method for producing fruit juice by which formation of a self-prevention type dynamic membrane is eliminated when filtered and transparent fruit juice containing a water-soluble pectin can be obtained and to provide an apparatus used for the production method.
SOLUTION: The method for producing the fruit juice comprises partially decomposing pectin in fruit juice with a pectolytic enzyme, clarifying and filtering the partially decomposed pectin with a microfilter (MF) membrane to obtain the transparent fruit juice containing a water-soluble pectin. The apparatus 11 for producing the juice is composed of a storage tank 1 for storing the juice, a circulation pump 2 for circulating the juice, a heat exchanger 3 for heating or cooling the juice, a MF membrane module 4 for filtering the juice and bypass piping 5 for by-passing the MF membrane module 4, and the apparatus 11 carries out partial decomposition of the juice and filtering of the juice after the partial decomposition.
