Embodiment 1

[0055] 1. Raw material pretreatment process

[0056] 1.1 Prepare 15 tons of 8% NaOH solution according to the quality of Eucheuma spinach, and heat it to 60°C, turn on the stirring and add 5% KCl, after it is completely dissolved, put it into a pot with 2 tons of spinach, and keep the temperature constant Soak for 4 hours. After soaking for 4 hours, put the lye into the recovery tank and pump it into the heating pot after sedimentation. Add water to spray the vegetables so that the total amount of lye is about 14 tons, and then add an appropriate amount of 30% lye to make the lye contain 8% (use the neutralization titration method to measure the lye content of the mother liquor, and calculate the amount of lye added). alkalinity).

[0057] 1.2 After the lye is prepared, the temperature starts to rise, and KCl is properly supplemented according to the glue retention of the hairy vegetables, 25kg per pot.

Abstract

The invention relates to a preparation method of carrageenan oligosaccharides. The preparation method sequentially comprises a raw material pretreatment process step, an extraction process step, an enzymolysis process step, a potassium chloride dissolution process step, a potassic alteration and dehydration process step, a squeezing process step, a sterilization process step, a crushing process step and a material mixing and re-sterilization process step, wherein an irradiation and degradation process step is further contained between the crushing process step and the material mixing and re-sterilization process step, and the irradiation and degradation process step is as follows: a semi-finished product obtained in the crushing process step is simply bagged and packaged, and then irradiated by an electronic accelerator with 10MeV and beam power of 500-650kW for 10-20h. A complex enzyme adopted by the invention has stronger destructive power against cellulose and high degree of carrageenan cracking, and can reduce the using quantity of steam and chemical raw materials in the production process of products and realize energy conservation, consumption reduction and clean production under the situation of ensuring the yield of the products. According to the preparation method provided by the invention, the irradiation method is adopted for degrading large molecular carrageenan into small molecular carrageenan, the addition of any impurities or harmful substances is avoided, and the degradation is fast and pollution-free.

Description

technical field [0001] The invention relates to a preparation method of carrageenan oligosaccharides, in particular to a method for preparing ultra-low viscosity carrageenan oligosaccharides by using a high-efficiency and energy-saving biological-physical combination method that can reduce costs, obtain products with stable properties, low molecular weight, and no chemical residues. sugar method. Background technique [0002] Carrageenan is a polysaccharide extracted from the cell wall of red algae. In the early days of our country, it was called carrageenan, carrageenan, and musk carrageenan, and it was later unified as carrageenan. Since polysaccharides are important components of all living organisms, they play an important role in controlling cell division and differentiation, regulating cell growth and aging, and maintaining the normal metabolism of living organisms. Therefore, the research on polysaccharides has been paid more and more attention by researchers. With ...
