Problems solved by technology

[0005] 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. CN101396161A discloses "a kind of xylitol corn silk vinegar beverage and its preparation method", but these patent applications are also equipped with other ingredients except corn silk in ingredients, and most of them also add preservatives, and these ingredients cover up The unique fragrance taste of corn silk is obtained; at the same time, the preparation method of corn silk aqueous extract adopts the method of boiling, so that the main aroma of corn silk is seriously lost, which affects the taste of the product

Embodiment 1

[0040] The preparation of embodiment 1 corn silk mineral water

[0041] (1) Take 5 kg of dry corn silk, remove impurities, wash, and put into a closed extraction tank;

[0042] (2) Preheat 1000L mineral water, divide the preheated mineral water into 3 parts, and carry out 3 times of heat extraction on the corn silk under the condition of 90 ℃, each time of heat extraction is 30min, each time of heat extraction Carry out solid-liquid separation after the extraction, and the filtrate is combined;

[0043] (3) The liquid part obtained by extraction is subjected to secondary filtration to obtain corn silk water extract;

[0044] (4) The corn silk extract was detected, and the contents of corn silk polysaccharides, total flavonoids and total saponins were 62.7mg / L, 29.2mg / L and 73.2mg / L, respectively.

[0045] (5) After being sterilized at 137°C for 4sec, it is cooled to 90°C for hot filling, bottle inversion, spray cooling, light inspection, and packaging. It is corn silk minera...

Abstract

The invention discloses corn stigma mineral water. The corn stigma mineral water is prepared from corn stigma and mineral water serving as raw materials, wherein the weight-to-volume ratio of the corn stigma to the mineral water is 0.1 to 1kg to 100L; the polysaccharide content of the corn stigma mineral water is 0.01 to 0.5g / L; the total saponin content is 0.01 to 0.1g / L; and the total flavone content is 0.01 to 0.1g / L. The invention also discloses a preparation method of the corn stigma mineral water; and the method comprises the following steps of: placing the corn stigma into a sealed container; adding preheated mineral water into the container; performing thermal extraction and solid-liquid separation; performing secondary filtration on the liquid part, sterilizing the liquid part ata high temperature and cooling the liquid part to 90 DEG C for thermal encapsulation; and pouring the liquid part into bottles, cooling the liquid part by spraying, performing visual inspection and packaging the bottles to obtain the corn stigma mineral water. The corn stigma mineral water does not have any preservative and has the health-care functions of antioxidation, diuresis, pressure lowering, blood sugar level regulation, enhancement of immunity of a body and the like, so that the corn stigma mineral water can replenish moisture required by human body every day in place of drinking water and can be used as a functional beverage for diabetic patients to play a part in prevention and health care.

Description

technical field [0001] The invention relates to corn silk mineral water and a preparation method thereof, belonging to the field of health beverage processing. 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 has confirmed that corn silk is a safe, non-toxic substance. [0003] At present, the application of corn silk is mainly used as a raw material and other traditional Chinese medicinal materials for formulating prescri...
