Problems solved by technology

[0002] The extraction and production steps of existing pectin are cumbersome, need to use large amounts of ethanol to clean, hydrolyze for a long time, and use activated carbon to decolorize, this process consumes a lot of energy, the ethanol consumption is large and the cost is high, and the impurity content of the obtained pectin powder is relatively high. High, the traditional heating extraction method requires high temperature and a long time, the pectin in the raw material will inevitably produce denaturation and decomposition

Embodiment 1

[0029] Embodiment 1: Take a portion of raw material particles of the pericarp with a thickness of about 6 mm, add 60 portions of 90°C high-temperature water and boil for 30 minutes, and keep stirring, add 45 portions of 85°C warm water to the pomace, add hydrochloric acid to dissolve Adjust the pH value of the solution to 2.0, stir and react for 90 minutes, filter the discarded residue to obtain an acidic solution, filter again to obtain a pectin clear liquid, and pass the obtained pectin clear liquid through an ion exchange column for decolorization until the color of the pectin clear liquid is light yellow , Concentrate the obtained light yellow pectin clear liquid through molecular sieves until the pectin content is 10%, and sterilize the tank.

Embodiment 2

[0030] Embodiment 2: Take a part of raw material particles of the peel of about 6 mm, add 60 parts of 90 ℃ high-temperature water and boil for 20 minutes, and keep stirring, add 45 parts of 85 ℃ warm water to the pomace, add hydrochloric acid to dissolve the pomace. Adjust the pH value of the solution to 2.0, stir and react for 90 minutes, filter the discarded residue to obtain an acidic solution, filter again to obtain a pectin clear liquid, and pass the obtained pectin clear liquid through an ion exchange column for decolorization until the color of the pectin clear liquid is light yellow , Concentrate the obtained light yellow pectin clear liquid through molecular sieves until the pectin content is 10%, and sterilize the tank.

Abstract

The invention belongs to the field of pectin extraction and manufacture and in particular relates to a process for producing liquid pectin. The process comprises the process steps: crushing the peel raw materials, digesting, performing primary filtering, extracting, performing secondary filtering, performing third-stage filtering, discoloring, desugaring, concentrating and filling. The process for producing liquid pectin is easy to operate and rapid in reaction, discoloring and desugaring are performed by utilizing an ion exchange column, the discoloring degree is high, impurities are prevented from being entrained, sieve concentration is repeatedly performed through molecules, the water, pigment, salt, sugar and small molecular substances can be completely removed, a high-purity pectin solution is obtained, the liquid pectin is filled in a vacuum mode, the outside pollution bacteria are isolated, and compared with the pectin powder, the liquid pectin is convenient to use and fast in absorption.

Description

technical field [0001] The invention belongs to the field of pectin extraction and production, and more specifically relates to a production process of liquid pectin. technical background [0002] The extraction and production steps of existing pectin are cumbersome, and need to use large amounts of ethanol for cleaning, long-term hydrolysis, and decolorization with activated carbon. This process consumes a lot of energy, and the ethanol consumption is large and costly. High, the traditional heating extraction method requires high temperature and a long time, and the pectin in the raw material will inevitably produce denaturation and decomposition. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production process of liquid pectin with simple and rapid production process and high pectin purity. [0004] In order to solve the above-mentioned technical problems, the invention provides a kind of production techni...
