Embodiment 1

[0016] Example 1 Weigh 5 tons of fresh chicory, wash and shred it, and transport it to a 30m 3 In the extraction tank, adjust the pH to 5.8-6.5, add 0.08 tons of cellulase, extract at 60°C for 3.0 hours, filter to remove the filter residue, and obtain a crude inulin extract. Under the conditions of temperature 35°C and pressure 1.5MPa, the feed liquid passes through a 0.5 μm ultrafiltration membrane to remove impurities such as ions and low-molecular organic matter, and then transfers it to a sterilizing tank at 95°C for pasteurization for 30 minutes to make the bacteria in the feed liquid Enzyme activity denatures, protein coagulates, cools to room temperature, and obtains a solution rich in inulin. Add 2.5% activated carbon to the tank, decolorize at 50°C for 30 minutes, filter to remove residual pigment; transfer the filtrate to a lime milk storage tank, add calcium hydroxide to adjust the pH to 10.0, treat at 80°C for 35 minutes, and filter to remove impurities; Pass ...

Embodiment 2

[0017] Example 2 Weigh 5 tons of fresh chicory, wash and shred it, and transport it to a 40m 3 In the extraction tank, adjust the pH to 5.8-6.5, add 0.12 tons of cellulase, extract at 60°C for 3.0 hours, filter to remove the filter residue, and obtain a crude inulin extract. Under the conditions of temperature 35°C and pressure 1.5MPa, the feed liquid passes through a 0.5 μm ultrafiltration membrane to remove impurities such as ions and low-molecular organic matter, and then transfers it to a sterilizing tank at 95°C for pasteurization for 30 minutes to make the bacteria in the feed liquid Enzyme activity denatures, protein coagulates, cools to room temperature, and obtains a solution rich in inulin.

Embodiment 3

[0018] Example 3 Weigh 5 tons of fresh chicory, wash and shred it, and transport it to a 50m 3 In the extraction tank, adjust the pH to 5.8-6.5, add 0.16 tons of cellulase, extract at 60°C for 3.0 hours, filter to remove the filter residue, and obtain a crude inulin extract. Under the conditions of temperature 35°C and pressure 1.5MPa, the feed liquid passes through a 0.5 μm ultrafiltration membrane to remove impurities such as ions and low-molecular organic matter, and then transfers it to a sterilizing tank at 95°C for pasteurization for 30 minutes to make the bacteria in the feed liquid Enzyme activity denatures, protein coagulates, cools to room temperature, and obtains a solution rich in inulin.

Abstract

The invention belongs to the field of new resource food processing, and particularly relates to a cichorium intybus inulin extracting method. The invention provides an inulin preparation method which is low in production investment, low in energy consumption, high in yield and high in quality. The cichorium intybus inulin extracting method comprises the following steps: cleaning and shredding fresh cichorium intybus serving as a raw material; adding the shredded cichorium intybus into an extracting tank to adjust the pH, and adding cellulose for extracting; performing ultra-filtration, activated carbon decolouring, lime milk impurity removal, ion exchange debitterizing, nano-filtration, vacuum concentration, spray-drying, and cooling processes on filtered clarified liquor in sequence; grading and packaging to obtain a finished product. According to the cichorium intybus inulin extracting method, the cichorium intybus inulin is extracted by adopting an enzymic method; compared with hot water extracting, the product extracting rate achieved by the enzymic method is increased; the inulin is further purified by adopting the ultra-filtration separating, the activated carbon decolouring and the ion exchange debitterizing. The invention relates to a continuous integrated process from the cichorium intybus serving as the raw material to the finally obtained high-purity inulin; the industrial production level of the inulin is promoted; the yield and the production efficiency are improved; the obtained product is good in quality and high in stability.

Description

technical field [0001] The invention belongs to the field of new resource food processing and relates to a method for producing inulin from chicory. Background technique [0002] endive( Cichorium intybus L.), also known as chicory and bitter chrysanthemum, is a perennial herb of the family Asteraceae. Native to Eurasia and North America, it is also distributed in Northwest my country, North China and Northeast China. Chicory has strong adaptability, likes warm and humid climate, and has the characteristics of tolerance to barrenness, cold, and drought. It is the main medicinal and edible economic crop in Gansu. Its leaves can be used as feed and high-grade vegetables, while the roots contain nearly 70% inulin (dry matter weight), which has good nutritional value and health care functions. [0003] Chicory is widely planted in many provinces and regions in my country, and the yield per mu can reach 3000Kg ~ 5000Kg. It is a semi-wild resource with good development prospec...
