Problems solved by technology

Pea peels are rich in crude fiber. There are foreign literature reports that the pectin in pea peels is rich in xylose, but there are few studies on the use of pea peels to produce l-arabinose. At present, l- The production of arabinose is difficult to crystallize directly due to the low content of arabinose in raw materials in industrial production. Chromatographic separation is often used to separate other miscellaneous sugars to obtain high-purity crystalline arabinose. However, this process is complicated. Difficulty in operation has become a bottleneck restricting the high production cost of l-arabinose

Abstract

The invention provides a process for preparing l-pectinose and xylose byproduct with pea pods as a raw material. The process for preparing the l-pectinose and xylose byproduct with the pea pods as the raw material comprises the steps of carrying out pretreatment on the raw material, carrying out low acid hydrolysis for extracting l-pectinose and carrying out high acid hydrolysis for extracting xylose, The process for preparing the l-pectinose and xylose byproduct with the pea pods as the raw material has the advantages that low acid is utilized for hydrolyzing the pea pod raw material, high content l-pectinose hydrolysate can be obtained by adopting a one-step decoloration-ultrafitration-desalination-concentration process, and crystallization is directly carried out for obtaining the l-pectinose without carrying out chromatographic separation, so that the production technology is simplified, the operation is simple, and the production cost is reduced; hydrolysis slag with l-pectinose removed is added with acid again to be hydrolyzed, and xylose is produced at the same time, so that the pea pod raw material is fully utilized; in treatment on hydrolysate, a saccharic acid membrane separation process is adopted for replacing the traditional acid neutralization process, so that part of acid liquor is recycled, sewage discharge is greatly reduced, intake of saline ions is avoided, a follow-up processing load is lightened, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of functional sugar preparation, and in particular relates to a process for preparing l-arabinose by using pea peel as a raw material and by-product xylose. Background technique [0002] Pea belongs to the leguminous plant, which originated in western Asia. Because of its strong adaptability, it has a wide geographical distribution all over the world. It has very high nutritional value, among which the starch content is the highest, reaching 52-55%. Many domestic vermicelli manufacturers The starch in pea is used as raw material to produce vermicelli, and the pea skin rich in crude fiber is used as a by-product as feed, and its added value is very low. There are few domestic researches on the utilization of pea skin. Therefore, it is urgent to develop a method to use pea The skin turns waste into treasure, creating higher economic value. Pea peels are rich in crude fiber. There are foreign literature report...
