Embodiment Construction

[0019] Depend on figure 1 It can be seen that a method for extracting sea cucumber peptides, the technological process includes: soaking, high-pressure cooking, enzymatic hydrolysis, deodorization, filtration, concentration, drying, and packaging of the finished product. Its process steps are characterized by:

[0020] (1) Soaking: Dried sea cucumber body wall is used as raw material, soaked in 3-4 times cold water in the soaking container, soaked for 8-10 hours, changed the water 4-5 times during the soaking, and removed the salt and tiny dust in the sea cucumber The grains and sediment impurities are decomposed, and there is no need to crush and grind after immersion; when the body wall of fresh sea cucumber is used as raw material: if the fresh sea cucumber has been boiled (and frozen) in advance, then (after thawing) use 3-4 times Soak in cold water for 3-4 hours, change the water 3-4 times during the process, decompose the salt in the sea cucumber, reduce the salt conten...

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. [0003] Collagen peptide is a degradation product of collagen. Compared with collagen, it has the advantages of small molecular weight, strong water solubility, and easy digestion and absorpt...
