Problems solved by technology

But at present, the planting of Jerusalem artichoke in my country has not been promoted on a large scale, and its reason is that the deep processing of Jerusalem artichoke has not been well developed, and key technical problems have not been solved.
In Northwest China, some enterprises use Jerusalem artichoke as raw material to produce inulin, but the products have problems of coloring and bitter taste.
Although the price is low in the market, the sales are not good

Embodiment 1

[0027]Under the condition of room temperature, wash 4000 grams of fresh Jerusalem artichoke root with clean water to remove the soil. Dissolve 20 grams of sodium hydroxide in 2 liters of water, heat to 100 degrees Celsius, put Jerusalem artichoke in the sodium hydroxide solution for 30 seconds, take it out, rinse with water, and peel off the skin to obtain light yellow skinless Jerusalem artichoke roots. Soak it in 3 liters of 0.1% sulfuric acid solution for 10 minutes, the Jerusalem artichoke root turns white. Cut Jerusalem artichoke into thin slices with a thickness of 0.5-2 mm, place in a 50 liter stainless steel bucket, add 4 liters of distilled water, and introduce steam. After boiling for 15 minutes, pour out the solution, add 2 liters of water again, and cook for 10 minutes. Filter out the liquid, add 2 liters of water to boil three times, and finally obtain the residue with a nylon filter cloth to squeeze and mix with the boiled liquid to obtain 11.65 liters of liquid....

Embodiment 2

[0029] Under the condition of room temperature, wash 4000 grams of fresh Jerusalem artichoke root with clean water to remove the soil. Dissolve 80 grams of sodium hydroxide in 2 liters of water, heat to 90 degrees Celsius, put Jerusalem artichoke in the sodium hydroxide solution for 60 seconds, take it out, rinse with water, and peel off the skin to obtain light yellow skinless Jerusalem artichoke roots. Soak it in 3 liters of 1% hydrochloric acid solution for 2 minutes, the Jerusalem artichoke root turns white. Cut Jerusalem artichoke into thin slices with a thickness of 0.5-2 mm, and dry naturally to obtain 800 grams of dry product. Add 800 grams of dried Jerusalem artichoke slices and 3200ml of water to soak in a 50-liter stainless steel bucket for 2 hours, add 4 liters of distilled water, and introduce steam. After boiling for 15 minutes, pour out the solution, add 2 liters of water again, cook for 10 minutes, and filter out liquid, and add 2 liters of water three times t...

Embodiment 3

[0031] Under the condition of room temperature, wash 4000 grams of fresh Jerusalem artichoke root with clean water to remove the soil. Dissolve 50 grams of sodium hydroxide in 2 liters of water, heat to 80 degrees Celsius, put Jerusalem artichoke in the sodium hydroxide solution for 120 seconds, take it out, rinse with water, and peel off the skin to obtain light yellow skinless Jerusalem artichoke roots. Soak it in 3 liters of 5% acetic acid solution for 1 minute, and the Jerusalem artichoke root turns white. Cut Jerusalem artichoke into thin slices with a thickness of 0.5-2 mm, and dry naturally to obtain 800 grams of dry product. Add 800 grams of dried Jerusalem artichoke slices and 3200ml of water to soak for 2 hours in a 50-liter stainless steel bucket, add 4 liters of distilled water, and introduce steam. After boiling for 60 minutes, pour out the solution, add 2 liters of water again, cook for 10 minutes, and filter out liquid, and add 2 liters of water three times to ...

Abstract

The invention relates to a producing method of the qualified inulin, specifically a systemic method for producing qualified inulin having the chicory as material, comprising having fresh / dry chicory tuberous root as material, flaying, soaking, slicing up, extracting in hot water, flocculated depositing, decompressure filtration, desalination by ion exchange column, decoloring by ion exchange column, decompressure concentration, finally spray drying or freeze drying to produce the inulin. The invention is a producing craft for extracting the qualified inulin from plants with a physical chemistry means and has a good product quality, a high safety, a relative simple producing craft.

Description

technical field [0001] The present invention relates to the production technology of high-quality inulin, in particular to a method for processing and producing high-quality inulin using Jerusalem artichoke as raw material. Filtration, ion exchange column desalination, ion exchange column decolorization, vacuum concentration and other treatment processes, spray drying or freeze drying to produce high-content, white, high-quality inulin without bitter taste and its application. Background technique [0002] Since the beginning of the 20th century, with the advancement of science and technology and the development of medical technology, the life span of human beings has made great progress. On the other hand, with the improvement of living standards, overeating, obesity, chemical pollution and other reasons have greatly increased various diseases of life, such as cancer, cardiovascular disease, diabetes, etc., which seriously endanger human health. [0003] The 21st century i...
