Biological method for extracting natural pectin from pectin-containing plant residues

The invention relates to a biological method for extracting natural pectin from pectin-containing plant residues .The method includes the steps of preprocessing, enzymolysis, purification, concentration, pectin settlement, drying and the like .Compared with the prior art, the pectin-containing plant residues serve as raw materials, lignin contained in the pectin-containing plant residues is degraded through the Fenton reaction, and cellulose and hemicellulose are decomposed with cellulase, so that pectin is naturally exposed .Thus, compared with an existing acid method, color, quality and gel strength of pectin are greatly improved, and pectin production efficiency is improved by nearly 20% .The use amount of cellulase is reduced to 30%, and accordingly the problem that a method for extracting pectin through the enzymic method is low in efficiency and high in cost is solved. 本发明涉及种从含果胶植物残渣中提取天然果胶的生物学方法，该方法包括预处理、酶解、纯化、浓缩、果胶沉淀与干燥等步骤。与现有技术相比，本发明以含果胶植物残渣为原料，利用芬顿反应降解含果胶植物残渣中含有的木质素，使用纤维素酶分解纤维素及半纤维素，使得果胶自然暴露出来，因此与现有
