Abstract

The invention discloses a preparation method of okra peptide, the prepared okra peptide and application. The preparation method comprises the steps of ultrasonic extraction of an okra extracting solution, heating, enzymolysis, enzyme deactivation, centrifugal filtration, concentration, dewatering, drying and the like. The okra peptide prepared by the method is applied to the fields of medical rawmaterials, health foods or beauty and cosmetics. According to the preparation method, the okra extracting solution is prepared firstly, effective components in okras are extracted, damage to the effective components of okras can be avoided, the extraction process of the okra extracting solution is high in operation controllability, enzymolysis is carried out on the extracting solution through an enzymolysis method, the okra peptide is prepared, and the enzymolysis purity is high. The extraction method is simple in process, low in cost and suitable for large-scale popularization. The prepared okra peptide further contains vitamins and various trace substances, and has a good health-care effect.

Description

technical field [0001] The invention belongs to the technical field of food processing, and specifically relates to a preparation method of okra peptide, the prepared okra peptide and its application. Background technique [0002] Okra, generally refers to coffee yellow sunflower, also known as okra, is an annual herb plant, the tender pods are tender and smooth, with unique flavor and high nutritional value. Its juice is mixed with pectin, bovine lactan and aranan. Its pectin is a soluble fiber. In addition, it is also rich in trace elements such as zinc and selenium in coffee amber, which is effective in enhancing the human body's anti-cancer and anti-cancer capabilities. In a word, okra has great utilization value in the field of modern health care. At the same time, because it is rich in vitamin C and soluble fiber, it has a health care effect on the skin and can whiten and tender the skin. Therefore, it is also widely used in the field of cosmetics. [0003] In the ...
