Embodiment 1

[0025] Extraction process of the present invention comprises the following steps:

[0026] Washing and extracting—clean the fresh chicory root with water to remove impurities; cut the washed fresh chicory root into shreds or thin slices; soak the shredded or thin sliced ​​chicory root in countercurrent with hot water to extract inulin. The ratio of parts by weight of the amount of chicory root is water: chicory rhizome=8:1; the extraction water temperature is maintained at 65 degrees Celsius, the extraction time is 80 minutes, and the residue is extruded after the extraction is completed to obtain the extraction sugar solution A;

[0027] Sterilize and kill enzymes—heat the extraction sugar solution A to 95 degrees Celsius, and carry out high-temperature sterilization and kill enzymes for 20 minutes;

[0028] Purification of sugar solution——the leaching sugar solution A after sterilization and enzyme elimination is subjected to chemical flocculation, separation and purificatio...

Embodiment 2

[0034] In the described cleaning and extracting step, the ratio of water consumption to the amount of chicory root in parts by weight is: water: chicory rhizome=5:1; the extraction water temperature is maintained at 60 degrees Celsius, and the extraction time is 100 minutes;

[0035] In the step of sterilizing and deactivating enzymes, heating the extracted sugar liquid A to 90 degrees Celsius, and performing high-temperature sterilization and deactivating enzymes for 30 minutes;

[0036] In the sugar solution purification step, the calcium hydroxide emulsion with a mass percentage concentration of 10% is put into the extraction sugar solution A to carry out the chemical reaction and flocculation of non-sugar substances, the temperature is controlled at 60 degrees Celsius, and the pH value is controlled at 10 -13, and then use phosphoric acid to reverse the pH to 7-8 to precipitate calcium phosphate;

[0037] In the step of refining the sugar solution, the sugar content in the...

Embodiment 3

[0042] In the cleaning and extracting step, the ratio of water consumption to the amount of chicory root in parts by weight is: water: chicory root=10:1; the extraction water temperature is maintained at 80 degrees Celsius, and the extraction time is 60 minutes;

[0043] In the step of sterilizing and deactivating enzymes, heating the extracted sugar solution A to 100 degrees Celsius, and performing high-temperature sterilization and deactivating enzymes for 10 minutes;

[0044]In the sugar solution purification step, the calcium hydroxide emulsion with a mass percentage concentration of 20% is put into the extraction sugar solution A to carry out the chemical reaction and flocculation of non-sugar substances, and the temperature is controlled at 90 degrees Celsius;

[0045] In the step of dehydrating and concentrating the sugar solution, evaporating and dehydrating and concentrating until the solid content (Brix) reaches 40%;

[0046] In the step of dehydrating and drying the...

Abstract

The invention relates to a preparation process for extracting inulin from cichory root, which mainly comprises the following steps: performing cleaning and extracting, sterilizing and inactivating enzyme, purifying sugar liquid, refining the sugar liquid, dehydrating and concentrating the sugar liquid, dehydrating and drying the sugar liquid, and reclaiming small molecular sugar. The preparation process overcomes the defects of process and equipment layout in the prior designed production process, reduces the total production cost, is safe and reliable, and has high extraction efficiency and rate of finished products.

Description

technical field [0001] The invention relates to a plant extraction process, in particular to a preparation process for extracting inulin from chicory roots, which belongs to the chemical extraction process. Background technique [0002] Inulin (inulin) and fructo-oligosaccharides have become an important functional food because of their clear structure and exact physiological and health functions. Japan's research, development and application are at the leading level in the world. The application and development in Europe, America and South Korea are also very fast. The research on functional fructo-oligosaccharides in my country started late in the 1990s, but developed rapidly in recent years. Jiangnan University undertook the National Science and Technology Commission's "Ninth Five-Year" research project to obtain scientific research results - enzymatic production of fructo-oligosaccharides, which is the third-generation health food functional factor, and is known as a hi...
