    • The present invention relates to a process by which a pectin extract is first de-esterified using a biocatalyst. Secondly, the resulting high molecular weight de-esterified pectin is further de-esterified and optionally amidated using conventional methods. Since the bio-catalyst may de-esterify to a DE of about 25%, conventional acid or alkali de-esterification and optionally amidation will have little impact on the molecular weight of the pectin in question because the number of ester groups have been substantially reduced in the first part of the process. In addition, the novel process leads to novel pectin compositions having higher molecular weight and higher intrinsic viscosity compared to known pectin compositions. These changes lead to low ester pectins providing gels of higher gel strength.
    • 本发明涉及通过该果胶提取物使用生物催化剂第一脱酯化的方法。 其次,将所得的高分子量脱酯化果胶是进一步去酯化和任选地使用的常规方法酰胺化。 由于生物催化剂可以脱酯化至约25%,常规的酸或碱脱酯化和任选酰胺化的DE将会对所讨论的果胶的分子量小的影响,因为酯基团的数目havebeen大幅减少 在该方法的第一部分。 此外,该新方法导致具有较高的分子量和较高的特性粘度相比于已知的果胶组合物新颖果胶的组合物。 这些变化导致低酯果胶提供的较高凝胶强度的凝胶。
