Embodiment 1

[0013] Example 1, mix 100 kg of citrus pomace crushed to 40 meshes with 1500 kg of 60°C water, stir and soak for 30 minutes, press the cleaned pomace with a belt press until the water content is 70%, and 333 kg of the squeezed citrus pomace Mix it with 3330kg of water, add hydrochloric acid to adjust the pH value to 2.3, then raise the temperature to 75°C, stir slowly, and keep warm for 3 hours; after the heat preservation is over, separate the pectin extract, after the solution is clarified, concentrate in vacuum, the vacuum degree is -0.85mpa , remove 75% of the water in the extract to obtain a concentrated pectin solution, add ammonia water to adjust the pH to 3.0, add 0.2‰ pectinase, and keep warm at 30°C for 6 hours. During the heat preservation process, pectinase can act on pectin At the specific site of the molecular chain, D-galacturonic acid α-1,4-glycosidic bond decomposes pectin into small molecular pectin. Through the control of reaction time, the molecular weight o...

Embodiment 2

[0014] Example 2, mix 100 kg of citrus pomace crushed to 30 meshes with 1500 kg of water at 65° C., stir and soak for 35 minutes, press the cleaned pomace with a belt press until the water content is 80%, and squeeze 500 kg of citrus pomace after pressing Mix it with 5000kg of water, add hydrochloric acid to adjust the pH value to 2.4, then raise the temperature to 70°C, stir slowly, and keep warm for 3.5 hours; after the heat preservation is over, separate the pectin extract, and after the solution is clarified, concentrate it in a vacuum with a vacuum degree of -0.95mpa. Remove 70% of the water in the extract to obtain a concentrated pectin solution, add ammonia water to adjust the pH to 3.0, add 0.3‰ pectinase, and keep warm at 40°C for 4 hours. During the heat preservation process, pectinase can act on pectin molecules Chain-specific site, D-galacturonic acid α-1,4-glucosidic bond decomposes pectin into small molecular pectin. Through the control of reaction time, the molec...

Embodiment 3

[0015] Example 3: Mix 100 kg of apple pomace crushed to 50 meshes with 1500 kg of 65° C. water, stir and soak for 40 minutes, press the cleaned pomace with a belt press until the water content is 75%, and mix 400 kg of squeezed pomace with Mix with 4000kg water, add hydrochloric acid to adjust the pH value to 2.5, then raise the temperature to 65°C, stir slowly, and keep warm for 4 hours; Extract 80% water to get pectin concentrate, add ammonia water to adjust pH to 3.0, add 0.4‰ pectinase, keep warm at 35°C for 5 hours, during the heat preservation process, pectinase can act on the pectin molecular chain At specific sites, D-galacturonic acid α-1,4-glycosidic bonds decompose pectin into small molecule pectin. Through the control of reaction time, the molecular weight of pectin is 12000g / mol-16000g / mol; the end of heat preservation Finally, vacuum low-temperature drying is adopted, the vacuum degree is -0.70mpa, and the temperature is 70°C to obtain a finished product.

Abstract

The invention provides a pectin manufacture technology. The pectin manufacture technology comprises the following steps: firstly, cleaning and washing peel pomace; secondly, performing hydrolysis; thirdly, performing separation and concentration; fourthly, performing enzymolysis on pectin: adjusting the pH value of the concentrate C to be 3.0-5.0, adding pectolase of 0.2-0.5 permillage, insulating at 30-45 DEG C for 4-6 hours, wherein during the insulation process, the pectolase can act on the specific position of the pectin molecular chain, a D-galacturonic acid Alpha-1,4-glucosidic bond locates and decomposes the original pectin into small molecules, and the molecular weight of the pectin is 10,000-20,000 g/mol; and fifthly, performing vacuum drying, adopting vacuum low-temperature drying with the vacuity of -0.70 to -0.80 MPa and the temperature of 60-70 DEG C to obtain the end product. According to the invention, an enzymic method degradation bio-engineering technology is adopted to reduce the molecule weight of the pectin to 10,000-20,000 g/mol; and the pectin after selective modification of the molecule chain has an obvious antitumor activity, and functions of removing in vivo heavy metal and adjusting blood sugar and blood fat.

Description

technical field [0001] The invention belongs to the technical field of fruit deep processing, and in particular relates to a pectin production process. Background technique [0002] Pectin is a kind of galacturonic acid polymer that constitutes the structural components of cells, and is widely found in the cell walls of roots, stems, leaves, and fruits of various plants. Practice has proved that pectin has the effects of anti-cancer, eliminating heavy metals in the body, regulating blood sugar and lowering blood lipids. Pectin can effectively bind lead in the human intestine, prevent it from being absorbed by the body, and excrete it with feces. However, the molecular chain of natural pectin is relatively small. Pectin is large and cannot be absorbed by the human body, so it cannot effectively eliminate blood lead and bone lead in the human body. In order to achieve the functions of anti-cancer and heavy metal removal in the blood with high activity pectin, a reasonable mole...
