Embodiment 1

[0026] The first step: Ultrasonic enhanced treatment of functional substances in mulberry leaves. Ultrasonic instruments available on the market are used. When the ultrasonic wave propagates in the medium, its mechanical energy is converted into the thermal energy of the medium in the vibration, and at the same time, the medium particles are periodically compressed to form a temperature-increasing center, thereby increasing the temperature of the medium; it can significantly increase the permeability of the solvent into the extract cell, Accelerate the mass transfer process, thereby strengthening the extraction process; it can effectively improve the permeability of the cell membrane and cell wall, reduce and eliminate the barrier layer between the solvent and the water phase, thereby increasing the mass transfer rate and improving the extraction efficiency.

Embodiment 2

[0033] The first step: Ultrasonic enhanced treatment of functional substances in mulberry leaves: Weigh 1.50Kg of mulberry leaves and mix them with 18L of water for ultrasonic enhanced treatment. The ultrasonic frequency is 200kHz, the power is 400W, and the ultrasonic treatment is 30min;

[0034] The second step: hot water stirring of feed liquid and water extraction: adjust the temperature of feed liquid to 60°C, adjust the pH value of feed liquid to 8.00, stir during the extraction process, the rotation speed is 60rpm, and the extraction time is 40min;

[0035] The third step: filter the feed liquid with a 200-mesh screen; repeat the previous step for the filter residue, then stir it with hot water twice, remove the filter residue and leave the filtrate, combine the obtained filtrate three times, and centrifuge at 3000 rpm for 20 minutes to obtain the supernatant;

[0036] Step 4: Thin film concentrates the supernatant until the soluble solid content reaches 50%, and seal it...

Embodiment 3

[0039] The first step: Ultrasonic enhanced treatment of functional substances in mulberry leaves: Weigh 1Kg of mulberry leaves and mix them with 18L of water for ultrasonic enhanced treatment. The ultrasonic frequency is 400kHz, the power is 500W, and the ultrasonic treatment is 50min;

[0040] The second step: hot water stirring of the feed liquid and water extraction: adjust the temperature of the feed liquid to 65°C, adjust the pH value of the feed liquid to 9.00, stir during the extraction process, the rotation speed is 50rpm, and the extraction time is 80min;

[0041] The third step: filter the feed liquid with a 200-mesh screen; repeat the previous step for the filter residue, then stir it with hot water twice, remove the filter residue and leave the filtrate, combine the obtained filtrate three times, and centrifuge at 3000 rpm for 20 minutes to obtain the supernatant;

[0042] Step 4: Thin film concentrates the supernatant until the soluble solid content reaches 50%, an...

Abstract

A mulberry leaf extract, a method and use of the same are disclosed in the invention. The mulberry leaf extract obtained by ultrasonication, water extracting and film concentrating contains multiple functional substances of polysaccharide, flavone and flavonoid glycoside, alkaloids, sterols, vitamins, amino acids, and the like, which has abroad application, especially is well applicable to tobacco production industry.

Description

technical field [0001] The invention relates to a mulberry leaf extract, its preparation method and application. Background technique [0002] Extracting functional substances from plants and effectively using them in the food and pharmaceutical industries has become an important research topic. Mulberry leaf is the leaf of Moraceae plant mulberry (Morus alba L.), which accounts for about 64% of the output of the upper part of the mulberry tree. The mulberry leaf can be picked 3-6 times a year, and its vitality is very strong. Planting mulberry and sericulture is a traditional industry of my country's agriculture. Mulberry has been cultivated in my country for more than 4,000 years. my country has several million mu of mulberry gardens and is the largest mulberry planting country in the world. Mulberry leaves are rich in protein, fat, carbohydrates, vitamins, calcium, iron, manganese, zinc and other elements, and are rich in essential amino acids and a variety of bioactive ...
