Abstract

The invention discloses a roselle and banana peel compound beverage. The compound beverage is prepared from raw materials in percentage by mass as follows: 13%-17% of banana peels, 0.4%-0.9% of roselle, 9%-12% of white granulated sugar, 0.2%-0.6% of an acidity regulator, 0.07%-0.12% of vitamin C and 70%-77% of water, wherein the acidity regulator is citric acid, phosphoric acid or malic acid. A preparation method of the compound beverage comprises the steps as follows: banana peel pulp is uniformly mixed with a pectase and cellulase compound enzyme liquid, the mixture is placed in a constant-temperature water bath for enzymolysis treatment, filtration and centrifugation are conducted, and banana peel juice is obtained; roselle water and the banana peel juice are mixed and homogenized, and flavoring of the beverage is conducted on the mixture. The process is simple to operate, no chemical extraction process is conducted, no pigment or essence is added, the natural flavor and drinking safety of the beverage are guaranteed, and the color of the product is light red and attractive; the beverage tastes sour and sweet, can promote appetite, has a light banana flavor and has good stability.

Description

technical field [0001] The invention belongs to the technical field of food processing, and more specifically relates to a compound beverage of roselle and banana peel and a preparation method thereof. Background technique [0002] Roselle is also known as roselle, roselle, mountain eggplant, Luoji; modern research shows that roselle contains flavonoids, protocatechuic acid, anthocyanins, isoflavones and rich amino acids, vitamins, sugars, organic acids, inorganic Salt and other chemical components can reduce cholesterol and triglycerides, inhibit the oxidation of low-density lipoprotein, inhibit platelet aggregation, reduce the formation of thrombus, reduce atherosclerosis, and can effectively prevent the occurrence of cardiovascular diseases. In addition, roselle also has the functions of protecting the liver and fighting cancer. Therefore, Roselle is a good natural health medicine. Mexican researchers also found that drinking roselle tea for a long time can also play a ...
