Problems solved by technology

The main defect of the current process of using Jerusalem artichoke and chicory to extract inulin is that: Jerusalem artichoke and chicory also contain high value-added resources such as fructooligosaccharides and high fructose syrup, but these resources have not been effectively extracted during the inulin extraction process , resulting in a waste of resources

Abstract

The invention discloses a Jerusalem artichoke / chicory comprehensive utilization method and is characterized in that the method comprises the following steps of: (1) removing impurities and shredding Jerusalem artichoke / chicory, continuously leaching Jerusalem artichoke / chicory shreds with 70 to 80 DEG C water, and performing solid-liquid separation to obtain a Jerusalem artichoke / chicory leaching solution and Jerusalem artichoke / chicory cake; (2) subjecting the leaching solution from the step (1) to ultrafiltration, resin desalting treatment and resin decoloration; (3) purifying the leaching solution from the step (2) by nano-filtration to obtain a nano-filtration dialysate and a nano-filtration concentrate, subjecting the nano-filtration concentrate to evaporation concentration and spray drying to obtain inulin; and (4) performing reverse osmosis concentration on the nano-filtration dialysate to form a reverse osmosis concentrate, and treating the reverse osmosis concentrate with DTF-01 chromatographic separation resin to obtain fructooligosaccharides and high fructose corn syrup. With the technical scheme, Jerusalem artichoke / chicory can be used to produce inulin, high fructose corn syrup and fructooligosaccharides. The method has the advantages of simple process and high production efficiency.

Description

technical field [0001] The invention relates to the field of artichoke / chicory production, in particular to a method for comprehensive utilization of artichoke / chicory. Background technique [0002] Jerusalem artichoke is a plant of the genus Sunflower in the Asteraceae family, also known as Jerusalem artichoke. It is a perennial herb of the genus Sunflower in the Asteraceae family. Native to North America, it was introduced to Europe in the 17th century and then to China. It blooms in autumn and has small yellow flowers shaped like chrysanthemums. It is generally propagated by tubers in production. Its underground tubers are rich in fructose polymers such as starch and inulin. They can be eaten, cooked or porridge, pickled vegetables, Sun-dried Jerusalem artichoke, or make starch and alcohol raw materials. Above-ground stems can also be added to working feed. Its tubers or stems and leaves are used as medicine, which has the effects of diuresis and dehumidification, ...
