Problems solved by technology

[0003] In the process of producing inulin from Jerusalem artichoke, the traditional process is generally to heat the aqueous solution of dried Jerusalem artichoke powder, which has disadvantages such as large water consumption, high energy consumption, low extraction rate, long process, and high cost.
At the same time, since Jerusalem artichoke itself also contains a large amount of polyphenols, it has the disadvantages of astringent taste and heavy pigment. The inulin produced by the existing technology is not only dark in color, which affects the senses, but also its unique astringent taste affects the mouthfeel. The value of the commodity is low

Embodiment 1

[0015] Take by weighing 50kg of fresh Jerusalem artichoke tubers, wash and remove silt with a washing machine, and after peeling, cut them into filaments with a shredder. Add the filaments to the extraction kettle and stir, add 100kg of deionized water, heat up to 90°C, keep for 30 minutes, filter with a centrifuge, return the filter residue to the extraction kettle, add 50kg of deionized water, heat up to 90°C, and stir for 15 Minutes, centrifugal filtration, the filter residue was extracted once with 50kg deionized water, and the filtrates were combined. Import the filtrate into the impurity removal reaction kettle, add calcium hydroxide solid powder to adjust the pH value to 13, stir for 30 minutes, and then introduce CO 2 Gas, adjust the pH value of the solution to 8, and produce flocculent precipitates. After centrifugal filtration, the filtrate passes through two-stage activated carbon columns, 732 cation exchange resin columns and D201 anion exchange resin columns in se...

Embodiment 2

[0017] Weigh 30 kg of fresh Jerusalem artichoke tubers, wash and remove silt with a washing machine, and after peeling, cut them into filaments with a shredder. Add the filaments to the extraction kettle and stir, add 50kg of deionized water, heat up to 100°C, keep for 30 minutes, filter with a centrifuge, return the filter residue to the extraction kettle, add 20kg of deionized water, heat up to 90°C, and stir for 15 Minutes, centrifugal filtration, the filter residue was extracted once with 20kg deionized water, and the filtrates were combined. Import the filtrate into the impurity removal reaction kettle, add calcium hydroxide solid powder to adjust the pH value to 12, stir for 30 minutes, and then introduce CO 2 Gas, adjust the pH value of the solution to 9, and produce flocculent precipitates. After centrifugal filtration, the filtrate passes through two-stage activated carbon column, D113 type cation exchange resin column and 717 type anion exchange resin column to remov...

Embodiment 3

[0019] Weigh 80kg of fresh Jerusalem artichoke tubers, wash and remove silt with a washing machine, and after peeling, cut them into filaments with a shredder. Add the filaments to the extraction kettle and stir, add 120kg of deionized water, heat up to 100°C, keep for 30 minutes, filter with a centrifuge, return the filter residue to the extraction kettle, add 50kg of deionized water, heat up to 90°C, and stir for 15 Minutes, centrifugal filtration, the filter residue was extracted once with 50kg deionized water, and the filtrates were combined. Import the filtrate into the impurity removal reaction kettle, add calcium hydroxide solid powder to adjust the pH value to 13, stir for 30 minutes, and then introduce CO 2 gas, adjust the pH value of the solution to 9, and produce flocculent precipitates. After centrifugal filtration, the filtrate passes through two-stage activated carbon column, 001X8 type cation exchange resin column and 711 type anion exchange resin column to remo...

Abstract

The invention discloses a method for manufacturing high-quality inulin, which comprises the following steps of peeling off fresh topinamber, cutting into filament, successively extracting in hot water at the temperature of 90-100 DEG C, filtering, entering activated carbon column, entering resin column of strong cation and strong anion, entering a nanofiltration (NF) system, and finally entering a spray dryer. The method in the invention has the following advantages: 1. high product purity, high production efficiency and low cost; 2. no astringency due to removal of polyphenol substances; and 3. lighter product pigment due to decoloration technique treatment.

Description

technical field [0001] The invention relates to a method for producing high-quality inulin using a saline-alkali-tolerant plant Jerusalem artichoke as a raw material. Background technique [0002] Jerusalem artichoke (Jerusalem artichoko), commonly known as Jerusalem artichoke, devil ginger, is a perennial herb belonging to the family Asteraceae, belonging to the genus Helianthus. The inulin in Jerusalem artichoke tubers is a kind of fructan formed by the dehydration polymerization of D-fructofuranose through 1 to 2 glycosidic bonds. As a natural functional polysaccharide, inulin has the prerequisite of water-soluble dietary fiber and biological activity Physiological functions of bifidobacteria, which have a super strong function of proliferating bifidobacteria, play an extremely important role in regulating body balance, restoring gastrointestinal function, improving immunity, promoting metabolism, preventing various diseases, and maintaining health, and can be widely used...
