Patent ID: 7166312

Claim:
A process comprising: a) purifying a pectin methyl esterase (PME) enzyme capable of block-wise enzymatically de-esterifying pectin; b) adding said purified pectin methyl esterase (PME) enzyme capable of block-wise enzymatically de-esterifying pectin to a pectin; c) preparing a block-wise enzymatically de-esterified pectin from said pectin by said purified pectin methyl esterase (PME) enzyme capable of block-wise enzymatically de-esterifying pectin; i) wherein said block-wise enzymatically de-esterified pectin is a high ester pectin; and ii) wherein said block-wise enzymatically de-esterified pectin contains from about 70% to about 80% ester groups; d) adding said block-wise enzymatically de-esterified pectin to an acidic foodstuff environment comprising at least one protein; and e) stabilising said protein by said block-wise enzymatically de-esterified pectin.
