Abstract

The invention relates to a method for separating pectin from fructus momordicae production waste residue. The method comprises: (1) hot water extraction: adding hot water to fructus momordicae production waste residue, carrying out stirring extraction, and filtering to obtain an extraction liquid; (2) micro-filtration: making the extraction liquid obtained in the step (1) pass through a ceramic membrane, and collecting a ceramic membrane permeation liquid; (3) nano-filtration: making the ceramic membrane permeation liquid obtained in the step (2) pass through a nano-filtration membrane, and collecting a nano-filtration membrane trapping liquid; (4) decolorizing: adding active carbon to the nano-filtration membrane trapping liquid obtained in the step (3), heating, carrying out thermal insulation stirring, and filtering to obtain a decolorizing liquid; and (5) concentration drying: carrying out pressure reducing concentration on the decolorizing liquid obtained in the step (4), and carrying out microwave drying to obtain the fructus momordicae pectin. According to the present invention, the fructus momordicae pectin obtained according to the method is light yellow powder, has the total galacturonic acid of more than or equal to 70%, and has excellent pectin quality and excellent pectin content; and the method uses the completely physical treatment method so as to provide advantages of safety, green properyy, and environmental protection.

Description

technical field [0001] The invention relates to a method for separating pectin, in particular to a method for separating pectin from waste residue produced from Luo Han Guo. Background technique [0002] Pectin is a kind of polymer polysaccharide, which has good gelling and emulsifying stabilizing effects. People pay more and more attention to its good functional superiority. It has been widely used in food, medicine, daily chemical and textile industries. [0003] Mangosteen is one of the first batch of precious Chinese herbal medicines with both medicinal and edible uses announced by the Ministry of Health. The purpose of domestic large-scale production and processing of Luo Han Guo is mainly to obtain the most economically valuable natural sweetener mogroside, which is 300 times sweeter than sucrose and does not produce calories. However, with the increasing market demand for mogroside, the annual processing volume of Luo Han Guo is also increasing, and at the same time,...
