Extraction method of sea cucumber polypeptide

Abstract

An extraction method of sea cucumber polypeptide contains steps of: embathing, high-pressure stewing, enzymatic hydrolysis, deodorizing, filtering, condensation, drying and finished product packaging. The extraction method is characterized in that high-pressure stewing: the temperature is 120-130 DEG C, the pressure is 0.13-0.15 MPa and stewing lasts for 2 hours at constant temperature and constant pressure; enzymatic hydrolysis: the temperature is cooled to 54-56 DEG C after heating and sterilizing, NaOH is added to adjust PH to 7.0 and 0.5% of sea cucumber special-purpose enzyme to perform enzymatic hydrolysis for 6 hours; deodorizing: 17% of active carbon is added for deodorizing; filtering: a standing liquid firstly passes through a candle filter, then passes through a barrel filter and is finally filtered to a clear liquid storage tank; and condensation: condensation pressure is minus 0.04-minus 0.06 MPa, condensation temperature is 75-80 DEG C, and Baume degree determined during the condensation process is controlled at 10. The invention has the following advantages of: sea cucumber is changed into a fully water soluble active component after biological enzyme hydrolysis; the content of small peptides in the product is high, which is more beneficial to the absorption and utilization of the sea cucumber active component; and sea cucumber polypeptide is more acceptable in taste after deodorizing by active carbon. The invention is suitable for the extraction method of sea cucumber polypeptide.

Description

technical field

[0001] The invention belongs to a production method of nutritional products, in particular to a method for extracting sea cucumber peptides by enzymolysis using dried and fresh sea cucumber body walls as raw materials. Background technique

[0002] In recent years, science believes that the human body absorbs protein mainly in the form of peptides. Peptides are molecules composed of amino acids with a molecular weight between 5000-200Da. They have strong activity and diversity, and can be used for physiological functions of peptide nutrition. and biological activity, regulate the physiological functions of various systems and cells in the human body, and activate relevant enzymes in the body. Therefore, various peptides have become important substances for human health.
