Method for preparing holothurin from waste solution of sea cucumber processing

Abstract

The technique to prepare saponin with sea-cucumber treatment waste liquid comprises, filtering the waste liquid to deposite with ethanol, placing, centrifuging; decompressing and condensing the supernatant to remove ethanol; forcing the condensed liquid to flow with velocity 1.5~2.0BV / h through macropore absorption resin; using water to elute and remove the salt, sugar and pigment with same flow velocity; using 60~70% ethanol elution liquid to elute the saponin absorbed on the resin; collecting the elution liquid to condense to extract shape; finally, freeze drying to obtain the product. this invention makes good use of the waste, has no pollutant to environment.

Description

technical field [0001] The invention relates to a process method for preparing sea cucumber saponins from sea cucumber processing waste liquid. Background technique [0002] Since ancient times, sea cucumbers have been one of the eight sea treasures, which belong to the class of sea cucumbers of the phylum Echinodermata. In the "Food Materia Medica" of the Ming Dynasty, it has long been pointed out that sea cucumber has many health-preserving functions such as nourishing vitality, nourishing internal organs, and eliminating deficiency and damage. With the improvement of people's living standards and the enhancement of health care awareness, the health care function of sea cucumbers has been more and more widely recognized and applied. In the trade and consumer market centered on the region, some products developed with sea cucumbers as raw materials have emerged accordingly, such as sea cucumber oral liquid, sea cucumber peptide nutritional capsules, sea cucumber wine, free...

Problems solved by technology

Usually the method of extracting sea cucumber saponins from sea cucumbers is to adopt the traditional organic solvent extraction method. The production of sea cucumber saponins by this type of method is not only cumbersome to operate, but also requires high equipment. A large amount of organic solvents (such as methanol) are used in the production process, polluting the environment, and The overall utilization rate of sea cucumbers is not high. After extracting sea cucumber saponins, other nutritional and active ingredients cannot be effectively utilized, causing a serious waste of sea cucumber resources.

Due to the limitations of the above reasons, at present, my country's research in this field is relatively backward, and the products developed are only limited to the processing of sea cucumber crude products, and most of the saponin components remain in the processing waste liquid during the processing process, and the waste liquid is obtained. Less than effective use, resulting in a great waste of resources
