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 drink and its preparation method" (200710113303.4), but these patent applications are also equipped with other ingredients except corn silk in terms of ingredients, and most of them also add preservatives. These ingredients mask the unique fragrance of corn silk; at the same time, the water extract of corn silk is prepared by boiling, so that the main aroma of corn silk is seriously lost, which affects the taste of the product

Abstract

The invention discloses corn silk water. The water beverage is prepared by using corn silk and purified water as raw materials, and the weight-volume ratio of the corn silk to the purified water is 0.1-1Kg: 100L, wherein in the corn silk water, the content of polysaccharide is 0.01 to 0.5g / L, the content of total saponin is 0.01 to 0.1g / L, and the content of total flavone is 0.01 to 0.1g / L. The invention also discloses a preparation method for the corn silk water. The method comprises the following steps of: putting the corn silk into a closed container, adding the pre-heated purified water into the container, and performing hot extraction and solid-liquid separation; and performing secondary filtration on the liquid part, then performing high-temperature sterilization, cooling the liquidto 90 DEG C, and performing hot filling, bottle pouring, spray cooling, lamp inspection and packing to obtain the corn silk water. The corn silk water is not added with any preservative, has the health-care functions of resisting oxidation, promoting urination, reducing pressure, reducing blood sugar, enhancing body immunity and the like, can replace drinking water to supplement water required by the human body every day, can be used as functional beverage for diabetes patients, and plays a role in prevention and health care.
