Embodiment 1

[0031] A method for extracting antioxidant water-soluble polysaccharides from abalone shells proposed by the present invention comprises the following steps:

[0032] (1) Cleaning: soak the abalone shells, which are the shells of variegated abalone, wrinkled plate abalone, sheep abalone, Australian abalone, ear abalone and white abalone, etc., remove the surface seawater salt, and wash off the abalone shell with clean water Sediment and fungal impurities on the surface.

[0033] (2) Soaking: Soak the abalone shell with 36% acetic acid solution for 6 hours to remove the surface material of the abalone shell.

[0034] (3) Drying: Drain the abalone shells and place them in a constant temperature blast drying oven, and adjust the temperature to 90°C to dry for 30 minutes.

[0035] (4) Crushing: crushing and grinding the dried abalone shells, and screening and filtering with a 200-mesh filter to obtain abalone shell powder.

[0036] (5) Extraction: Soak in water, and fully stir a...

Abstract

The invention discloses a method for extracting oxidation-resistant and water-soluble polysaccharide from abalone shells. The method comprises the steps as follows: S1, cleaning: soaking the abalone shells, removing seawater salt on the surface, and washing sediment and fungus impurities on the abalone shells with clear water; S2, soaking: soaking the abalone shells with an acetic acid solution for 6-10 h to remove surface substances of the abalone shells; S3, drying: draining the abalone shells and placing the abalone shells in a constant-temperature blast drying oven for drying at 90-100 DEGC for 30-50 min; S4, crushing: crushing and grinding the dried abalone shells and performing filtration to obtain abalone shell powder; S5, extraction: adding water for soaking, performing sufficientstirring extraction at 60-85 DEG C for 1-5 h, and performing suction filtration to remove residues; performing extraction for 2-3 times and mixing supernatants. Active polysaccharide in an extract isheteropolysaccharide and has higher activity for scavenging superoxide radicals and can be prepared into an antioxidant, the abalone shell resource is fully utilized, waste is changed into wealth, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of by-products of aquatic product processing, in particular to a method for extracting antioxidant water-soluble polysaccharides from abalone shells. Background technique [0002] Fujian Province is rich in abalone production resources, and the output in 2016 has exceeded 100,000 tons. Therefore, the variety and output of abalone processed products are also increasing to increase the added value of products, and a large amount of abalone shells will inevitably be produced during processing. [0003] Abalone shell, also known as Shicaiming, is the shell of variegated abalone, wrinkled pan abalone, sheep abalone, Australian abalone, ear abalone and white abalone. Abalone shell is composed of cuticle, prism layer and nacre layer. The chemical composition includes 95% calcium carbonate and 0.3%~5% organic matter. The water-soluble organic matter in abalone shells is mainly a mixture of glycoproteins, phosphopro...
