Problems solved by technology

However, water extraction often extracts a variety of complex components, and high-temperature decoction and concentration will cause damage to the functional components in the raw materials, resulting in changes in the quality and taste of health tea
Currently on the market, the health care instant tea prepared with okra leaf extract, green tea, chrysanthemum, jasmine tea and okra flower extract as the main formula, especially the use of okra leaf for product development has not been reported.

Embodiment 1

[0029]1. Preparation of okra leaf extract: okra leaves are dried in the sun or air-dried at room temperature, gently kneaded, then placed in a tissue crushing extractor, and 10 times the amount of 70% aqueous ethanol or 70% aqueous acetone is added each time to crush and extract twice. 3 minutes each time. Suction filtration, combined filtrates, vacuum film concentration below 50°C to 1 / 5 of the original volume, and then add activated carbon for decolorization and degreasing treatment. The operation steps are to decolorize the obtained concentrate with powdered activated carbon at a temperature below 50°C for 30 minutes, the amount of activated carbon is 2% of the amount of okra leaf extract, decolorize once, filter with suction, remove the activated carbon, and continue to decolorize the filtrate at 50°C The following vacuum thin film concentration was carried out to 1 / 10 of the original volume. The concentrate is spray-dried into dry powder to obtain the okra leaf extract, ...

Embodiment 2

[0033] 1. Preparation of okra leaf extract: okra leaves are dried in the sun or air-dried at room temperature, gently kneaded, then placed in a tissue crushing extractor, each time adding 8 times the amount of 50% aqueous ethanol or 50% aqueous acetone to crush and extract 3 times , 2 minutes each time. Suction filtration, combined filtrates, vacuum film concentration below 50°C to 1 / 4 of the original volume, and then add activated carbon for decolorization and degreasing treatment. The operation steps are to decolorize the obtained concentrate with powdered activated carbon at a temperature below 50°C for 25 minutes, the amount of activated carbon is 1.5% of the amount of okra leaf extract, decolorize once, filter with suction, remove the activated carbon, and continue to decolorize the filtrate at 50°C The following vacuum thin film concentration was carried out to 1 / 8 of the original volume. The concentrate is spray-dried into dry powder to obtain the dry powder of the okr...

Embodiment 3

[0037] 1. Preparation of okra leaf extract: okra leaves are dried in the sun or air-dried at room temperature, then lightly kneaded, then placed in a tissue crushing extractor, each time adding 7 times the amount of 75% aqueous ethanol or 75% aqueous acetone to crush and extract 3 times , 5 minutes each time. Suction filtration, combined filtrates, vacuum film concentration below 50°C to 1 / 4 of the original volume, and then add activated carbon for decolorization and degreasing treatment. The operation steps are to use powdered activated carbon to decolorize the obtained concentrate by ultrasonic at 50°C for 20 minutes. The amount of activated carbon is 1.2% of the amount of okra leaf extract. The following vacuum film concentration was carried out to 1 / 9 of the original volume. The concentrated solution is vacuum-dried into a dry powder to obtain the dry powder of the okra leaf extract, the water content is controlled to be less than 5%, and the yield of the okra leaf extrac...

Abstract

The invention discloses an abelmoschus manihot leaf extract and a production method of a health-care instant tea thereof, which belong to the technical field of health-care foods. The health-care instant tea is prepared by uniformly mixing the following materials in percentage by weight: 50 to 60 percent of dry abelmoschus manihot leaf extract powder, and 40 to 50 percent of green tea, chrysanthemum, jasmine tea and abelmoschus manihot flower extract powder. The prepared product has high purity of functional components and good quality, is convenient to carry and drink, expands and increases the utilization of the abelmoschus manihot resource, and has the nutritional and health-care functions of resisting fatigue and ageing, helping digestion, promoting digestion and moistening the intestine, clearing fire and improving eyesight, protecting liver and strengthening kidney, reducing blood fat, strengthening physical endurance and immunity of the organism and the like.

Description

technical field [0001] The invention belongs to the technical field of health food, and specifically relates to a production method of an okra leaf extract and a health-care instant tea. Background technique [0002] Okra [ Abelmoschus esculentus (L.) Moench] is an annual herbaceous plant of the genus Okra in the Malvaceae family, also known as croissant, kidney-tonifying grass, etc. There is distribution and cultivation of okra in the north and south of my country.
