Pectinase Preparation for Making Clarified Orange Juice

Part VII. Effect of low molecularization of pectin in juice for the clarification

Abstract

Decomposition of pectin or orange juice by mechanical method and the effect of this method on the clarification were investigated.
Impact Cell Mill developed in Kyushu University for the crushing single cell organisms was applied for crushing the pectin substances.
The behaviors of the pectin obtained by this treatment was as same as that of the pectin treated with an acid stable hemicellulase.
The clarification of orange juice with pectinase preparation was acceleated by the preliminary crushing of pectin substance with a machine such as Impact Cell Mill and this method is supposed to be recommended for practical orange juice making.
