Fruit-flavored beverage and preparation method thereof

Abstract

The invention provides a fruit-flavored beverage. The fruit-flavored beverage comprises 189 g-387 g of purified water, 1 g-2 g of fruit juice, 0.1 g-0.2 g of dark plum powder, 10 g-20 g of white granulated sugar, 0.0045 g-0.09 g of disodium ethylene diamine tetraacetate, 0.3 g-0.6 g of sodium alginate, 0.4 g-0.8 g of a citric acid monohydrate, 0.12 g-0.24 g of potassium sorbate, 0.12 g-0.24 g of sodium citrate and 0.05 g-0.1 g of a yeast extract, wherein the ratio of the potassium sorbate is lower than 0.5%. The invention also provides a preparation method of the fruit-flavored beverage. According to the fruit-flavored beverage and the preparation method thereof, by adding the yeast extract, proteins containing sulfhydryl groups and an enzyme containing sulfhydryl groups in the cell wall of the fruit juice are protected from damage, so that anthocyanin in the natural fruit juice is prevented from being easily oxidized by air and accordingly turning into different colors, the fresh color of the fruit juice is thus kept, and consumers are attracted to purchasing the beverage.

With the continuous improvement of the overall consumption level of consumers, people's attention and awareness of health are also constantly improving. For beverages, people have gradually changed from seeking taste to health, and fruit-flavored beverages came into being. [0003] The existing fruit-flavored beverage processing technology is prone to react with the thickener sodium alginate and stabilizer EDTA (disodium ethylenediaminetetraacetic acid) to produce precipitation due to the added fruit juice containing a large number of ions, which is unstable, and the Anthocyanins are easily oxidized by the air and change color. The color of the beverage is not good and cannot attract consumers, resulting in poor sales of fruit-flavored beverages...
