Abstract

The invention discloses a process of enriching nutritional components of sea cucumber processing liquid. The process comprises the following steps: filtering and centrifuging the sea cucumber processing liquid, adding NaHCO3, Na2CO3 and a mixed solution, adding a HCl solution of 0.2 to 0.5 moL / L, putting into a PDMS membrane bioreactor, and performing pervaporization to obtain concentrated liquid;and sterilizing the concentrated liquid by a pasteurization method and performing cold storage at 4 DEG C for later use. The sea cucumber processing liquid is treated by the process provided by the invention, so that the nutritional components of the sea cucumber processing liquid can be enriched and recycled, the discharged liquid of the treated sea cucumber processing liquid is condensed watervapor, and pollution to the surrounding environment is reduced.

Description

technical field [0001] The invention relates to a method for processing sea cucumber working liquid, in particular to a process for enriching and recycling the operating components of sea cucumber working liquid. Background technique [0002] Sea cucumber working liquid is the waste liquid in the process of sea cucumber transportation and processing. During the process of soaking sea cucumbers, due to the autolysis of sea cucumbers, nutrients such as protein, polysaccharides and amino acids in sea cucumbers are lost into the soaking liquid, so the sea cucumber working liquid is rich in Contains various nutrients that are beneficial to the human body, and some ingredients even exceed the soaked sea cucumber itself. However, most of the treatment methods for sea ginseng working fluid are directly discarded, which not only causes the loss of nutrients, but also pollutes the surrounding environment. Contents of the invention [0003] In order to overcome the defects of enviro...
