Embodiment 1

[0020] Taking the tender fruit of 100kg okra as an example, the steps are as follows:

[0021] (1) raw material pretreatment, okra tender fruit removes impurities, rinses with clear water, transfers to tissue pulverizer to pulverize;

[0022] (2) Ultrasonic-assisted hot water extraction, the processed raw materials are transferred to the extraction equipment, and pure water is added according to the mass ratio of 1:6, the temperature is 55°C, and the power is 1800W. Ultrasonic-assisted extraction is 3.5h, and the extraction is completed and collected separately Extract and filter residue;

[0023] (3) Alcohol extraction of the filter residue, the filter residue obtained in step (2) is transferred to the extraction equipment, and 95% ethanol solution is added according to the mass ratio of 1:4 for reflux extraction for 3.5 hours, and the extract is fully collected;

[0024] (4) Concentrate in vacuo, combine the water extract and the alcohol extract obtained in the above two st...

Abstract

The invention discloses a preparation process of okra extractive dry powder, comprising the following steps of: (1) pretreating raw materials: cleaning okra fruit; grinding the okra fruit by a grinder; (2) conducting water extraction: adding 5-10 times of hot water the temperature of which is 50-60 DEC G to carry out ultrasonic-assisted extraction, and collecting extracting solution; (3) conducting filter residue alcohol extraction: refluxing and extracting okra filter residue subjected to water extraction by adding 95% of ethanol solution, and collecting alcohol extract; (4) conducting vacuum concentration: combining the water extract and the alcohol extract; carrying out vacuum concentration and recycling a solvent; and (5) conducting freeze drying: drying the concentrated extract in vacuum at a lower temperature so as to obtain the okra extractive dry powder. Nutritional ingredients and active substances of the okra can be obtained maximally by the method; the defect of incomplete extraction caused by single water extraction or alcohol extraction is effectively solved; and the obtained product is not only convenient to store and transport, and also can be directly applied to the fields such as healthcare food, beverage, cosmetic and medicine.

Description

technical field [0001] The invention belongs to the field of natural product extraction, in particular to a preparation process of okra extract dry powder. Background technique [0002] Okra is an annual herb of Malvaceae okra, also known as coffee ambrette, okra, etc. The tender fruit is rich in protein, free amino acids, rich in Vc, Va, Ve and phosphorus, iron, potassium, calcium, zinc, manganese It is a new type of health-care vegetable with high nutritional value. Okra is widely grown in tropical and Mediterranean climate zones. It is a plant distributed in the tropics to subtropics. In addition to being used as a daily vegetable, okra also has health benefits such as anti-fatigue, strengthening the stomach and protecting the liver, reducing lung damage, and improving the body’s immunity. Function, known as "plant Viagra", "green ginseng". [0003] The countries of origin of okra are mainly India, the United States and Africa. After the successful introduction in the C...
