Extraction technology of hijiki polysaccharide

Abstract

A hijiki polysaccharide extraction process, 1) inject 3 tons of water into No. 1 tank; 2) add 300kg of raw materials to No. 3 tank, stir and extract; 3) release the extract in No. 3 tank and pour into No. 2 tank; 4 ) Add the enzyme directly to the No. 2 tank, dissolve it, and place it for 14 hours to be reacted; 5) Pour the liquid in the No. 2 tank into the No. 1 tank, stop when the liquid in the No. 1 tank is concentrated to 700kg, and start centrifugation The liquid after the centrifugation is put into the No. 2 tank, and after the centrifugation, start to concentrate and centrifuge for the second time; 6) the concentrated solution in the No. 2 tank is put into the decolorization tank, adjust the pH to 9 with ammonia, add hydrogen peroxide until it becomes Yellow; 7) After the decolorization is completed, put it into the alcohol precipitation tank, add ethanol, stir and let stand; 8) Filter the ethanol alcohol precipitation solution, add water to the filtered precipitate, redissolve in the deproteinization tank, and volatilize the ethanol; 9) The dissolved solution is filtered in a centrifuge, and the recovered supernatant is sent to the spray drying station; 10) Spray drying is carried out, and the content and protein of the product are detected.

Description

Technical field [0001] The invention relates to the technical field of bioengineering, in particular to a hijiki polysaccharide extraction process. Background technique [0002] Hijiki belongs to the genus Phaeophyta, Cyclades, Fucus, Sargassoceae, and Sargassum. The algae are yellow-brown, plump and juicy, 15 to 40 cm high, up to 2 meters or more. The algae body is composed of false roots, stems, leaves and air sacs. The false root is a sucker-shaped base retainer, and the stem is an upright cylindrical main branch, with leaves and airbags in the shape of serrations in the north; linear or rod-shaped in the south. The algae body is fresh yellowish brown, and the dry product is black. The leaves vary greatly and have many shapes. It grows on rocks in the low tide zone and is mostly distributed along the coast of my country, from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south, with the most in the Zhejiang coast. Hijiki is recognized as the most edi...

Problems solved by technology

Most of the various nutrients mainly composed of hijiki polysaccharides are water-soluble substances, so they can be extracted by hot water extraction; this extraction method is simple, feasible, easy to operate, and does not require high equipment, but its production The time is long, the polysaccharide yield is not high, and the waste is serious

The acid leaching method is easy to destroy the specific structure related to immune activity in polysaccharides, and both methods have their shortcomings
