Problems solved by technology

Because the corn silk water extract has a good health care effect, people begin to develop health drinks with corn silk as the main raw material. No. CN1159301A discloses "a plant health drink and its production process", but these patents all belong to liquid drinks, which increase the cost during transportation and are inconvenient to carry
Chinese Patent Publication No. CN1382484A discloses corn silk injection and its preparation method, but corn silk injection has safety risks, and its production cost is also higher than other formulations

Embodiment 1

[0018] Example 1 Preparation of corn silk extract by ultrasonic-assisted semi-bionic method

[0019] A. After the corn silk is cleaned and dried, add 10 times the weight of corn silk in an aqueous solution of pH 7.5 for ultrasonic extraction. The aqueous solution of pH 8.3 was ultrasonicated for 1 hour, filtered, and the obtained filtrates were combined and concentrated under reduced pressure to obtain a liquid corn silk extract; this liquid corn silk extract can be used as a raw material for preparing its solid beverage.

[0020] B is: the concentrated solution obtained in step A is frozen at -80°C for 24 hours, and then freeze-dried at -48°C and an air pressure of 0.05mbar for 48 hours, crushed through a 60-mesh sieve, and made into a freeze-dried powder; this freeze-dried powder is also It can be used as a raw material for preparing its solid beverage.

Embodiment 2

[0021] Example 2 Preparation of corn silk extract by ultrasonic-assisted semi-bionic method

[0022] A. After the corn silk is cleaned and dried, add 20 times the weight of corn silk in an aqueous solution of pH 7.0 for ultrasonic extraction. The pH 8.1 aqueous solution was ultrasonicated for 0.5 hours, filtered, combined and extracted filtrates, and concentrated under reduced pressure to obtain a liquid corn silk extract; this liquid corn silk extract can be used as a raw material for preparing its solid beverage.

[0023] B is: the concentrated solution obtained in step A is frozen at -60°C for 36 hours, and then freeze-dried at -60°C and an air pressure of 0.05mbar for 72 hours, crushed through a 60-mesh sieve, and made into a freeze-dried powder; this freeze-dried powder is also It can be used as a raw material for preparing its solid beverage.

Embodiment 3

[0024] Example 3 heating reflux method to prepare corn silk extract

[0025] A. After the corn silk is cleaned and dried, the corn silk is extracted twice with 10 times the weight of water heating and reflux, each time for 1 hour, the extracts are combined, and the corn silk extract is obtained by concentrating under reduced pressure; this extract can be used to prepare its solid beverage raw materials.

[0026] B is: the concentrated solution obtained in step A is frozen at -80°C for 24 hours, then freeze-dried at -48°C and an air pressure of 0.05mbar for 48 hours after freezing, and crushed through a 60-mesh sieve to make a freeze-dried powder; this freeze-dried powder is also It can be used as a raw material for preparing its solid beverage.

Abstract

The invention discloses a corn stigma solid beverage and a preparation method thereof. The corn stigma solid beverage is prepared from the following raw materials in parts by weight: 10 to 60 parts of corn stigma extract, 10 to 60 parts of newtol and 10 to 60 parts of stevioside. The invention also discloses the preparation method of the corn stigma solid beverage. The corn stigma solid beverage provided by the invention has the functions of reducing blood glucose, reducing blood fat, diuresis and the like, and unique fragrant taste of corn is kept during dissolving.

Description

technical field [0001] The invention relates to the field of solid beverage processing. More specifically, it relates to a corn silk solid beverage and a preparation method thereof. Background technique [0002] Corn silk (stigma maydis) is the style and stigma of maize, a plant of the grass family Yushu. In my country, corn silk has a long history of clinical use as a traditional Chinese medicine. Studies have shown that corn silk contains a variety of biologically active components, such as flavonoids and their glycosides, sterols, alkaloids, sugars, organic acids, volatile oils, trace amounts Elements and multivitamins, etc., its extracts have anti-oxidation, diuretic, hypoglycemic, antibacterial, antihypertensive and immune-enhancing effects. The US Food and Drug Administration recognizes corn silk as a safe, non-toxic substance. [0003] In recent years, due to its safety and easy availability, the research on corn silk has been increasing year by year, and various co...
