Embodiment Construction

[0022] Depend on figure 1 Visible, a kind of extraction method of maca peptide, its technological process comprises: high-pressure cooking, enzymolysis, adsorption, filtration, concentration, drying, finished product packaging, and its technological step characteristic is:

[0023] (1) High-pressure cooking: Take 2500 grams of dry maca, add 10 times of water, put it in a cooking tank at a temperature of 124°C and a pressure of 0.14 MPa, cook at constant temperature and pressure for 1 hour, and drain the maca extract into the soup storage tank. slag discharge;

[0024] (2) Enzymolysis: the extract is discharged from the soup storage tank into the hydrolysis tank, heated and sterilized, then cooled to 53°C, added NaOH to adjust the pH=7.0, and then added 0.5% (calculated as dry matter) maca special enzyme, Enzymolysis for 3.5 hours, stirring for 2 minutes every 0.5 hours during the enzymolysis process, so that the enzymolysis can be carried out evenly and fully;

[0025] (3) A...

Abstract

The invention discloses a method for extracting maca peptide. The method comprises the steps of high-pressure cooking, enzymolysis, adsorption, filtration, concentration, drying and finished product package, and is characterized in that during high-pressure cooking, the temperature is 124 DEG C, the pressure is 0.14MPa, and constant-temperature and constant-pressure cooking is performed for 1 hour; during enzymolysis, the temperature is reduced to 53 DEG C after heating sterilization, NaOH is added to adjust the pH value to be 7.0, and 0.5% of a maca special enzyme consisting of an incision enzyme, an excision enzyme and a flavor enzyme is added to perform enzymolysis for 3.5 hours; during adsorption, 4% of active carbon is added to perform adsorption; during filtration, a standing solution is filtered through a barrel filter, then passes through a sheet frame serving as a protection filter, and finally is filtered into a clear solution storage tank; during concentration, the concentration pressure is minus 0.5MPa, the concentration temperature is 80 DEG C, and the Baume degree is determined during concentration. The method disclosed by the invention is simple in process and high in extraction rate, and is suitable for extracting the maca peptide.

Description

technical field [0001] The invention belongs to maca nutritional preparations, in particular to a method for extracting small-molecule peptides of maca by using dry maca as a raw material and utilizing enzymatic hydrolysis technology. 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 5000-200Dalton. 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] Peptide is a degradation product of protein. Compared with protein, it has the advantages of small molecular weight, strong water solubility, and easy digestion and absorption by ...
