Problems solved by technology

[0007] Most of the functional components of hemp are extracted directly with organic solvents. The traditional extraction and refining methods are solvent cooking, purification, refining and other steps. There are many extraction steps, high energy consumption, complicated process and low extraction rate.

Embodiment 1

[0016] Embodiment 1: (1) Steam explosion: Cut the hemp stalk into about 5 cm, soak it, add material to the steam explosion tank after soaking for 1 hour, maintain the pressure at 1.5 MPa for 5 minutes, and then explode.

[0017] (2) Recovery of xylo-oligosaccharides from the steam-explosion raffinate: after the steam-explosion treatment, there is a small amount of steam-explosion raffinate in addition to the solid fiber material, and the xylo-oligosaccharide concentrate can be obtained after the concentration treatment.

[0018] (3) Recovery of xylooligosaccharides by water washing of solid steam-exploded fiber materials: after the solid materials are washed with water, the functional components adsorbed on the surface of the fibers are recovered, and then the washing solution is concentrated.

[0019] (4) Mix the concentrate in step (2) and step (3), then pass through ion exchange, membrane filtration, microfiltration, nanofiltration to obtain a syrup product of 50% xylooligos...

Embodiment 2

[0021] Embodiment 2: (1) steam explosion: cut the apocynum stalk into about 5 cm, soak it, add material to the steam explosion tank after soaking for 1 hour, hold the pressure for 5 minutes under a pressure of 1.5 MPa, and then explode to get final product.

[0022] (2) Recovery of steam explosion residual liquid: after steam explosion treatment, there is a small amount of steam explosion residual liquid in addition to solid fiber materials, and concentrated solution of soluble functional components can be obtained after concentration treatment.

[0023] (3) Recovery of xylooligosaccharides by water washing of solid steam-exploded fiber materials: after the solid materials are washed with water, the functional components adsorbed on the surface of the fibers are recovered, and then the washing solution is concentrated.

[0024] (4) Mix the concentrate in step (2) and step (3), and then pass through ion exchange, membrane filtration, microfiltration and nanofiltration to obtain ...

Abstract

The invention pertains to the field of hemp resource utilization. Such functional components as flavonoids, Xyol-Oligosaccharides and the like generated after the steam exploded treatment on the hemp have very high medical value and application value. The invention relates to a method for extracting and separating soluble functional components in hemp in a steam exploded manner, which provides a high-valued means for the comprehensive utilization of hemp. After the steam exploded treatment on the hemp, concentration, ion exchange, membrane filtration, microfiltration and nanofiltration are carried out to obtain such effective elements as flavonoids, Xyol-Oligosaccharides, etc. The process opens a new way for the high-valued utilization of the steam exploded hemp, provides a new direction for the highly efficient extraction of functional components in the hemp and supplies a new method for the comprehensive utilization of hemp resources.

Description

technical field [0001] The invention belongs to the field of utilization of hemp resources, in particular to a method for steam explosion extraction and separation of soluble functional components in hemp. Background technique [0002] Hemp plants belong to Moraceae, annual herbs, dioecious. The most common types of hemp in my country are hemp, flax, ramie, kenaf, jute, sisal and apocynum. According to incomplete statistics, there are nearly 20 types of hemp and more than 6,500 varieties. It is the country with the richest hemp resources in the world. Hemp plants were once an important fiber, oil, and food crop for humans. The utilization of hemp in my country is mainly based on fiber, and the traditional methods are making rope, making sacks and weaving hemp. With the strengthening of people's health awareness, the medicinal value of various hemp plants is constantly being developed. [0003] The main chemical components of hemp raw materials include: cellulose (cellulos...
