The invention relates to the technical field of beverage
processing and in particular relates to a health-care compound fruit and vegetable beverage and a preparation method thereof. By adopting a single-factor testing method, the optimal formula percentage of raw materials is obtained through sensory evaluation and determination of light
transmittance, pH (Potential of
Hydrogen),
soluble solids and total
sugar: 27 percent to 29 percent of
snow pear juice, 10 percent to 15 percent of sweet tamarind juice, 26 percent to 28 percent of mangosteen juice, 30 percent to 32 percent of tomato juice, 33 percent to 35 percent of
carrot juice, 3 percent to 5 percent of ginger juice, 3 percent to 4 percent of brown
sugar, 4 percent to 5 percent of
proteoglycan, 0.029 percent to 0.031 percent of
citric acid, 0.01 percent to 0.03 percent of a color protection agent, 5 percent to 7 percent of a compound
enzyme and 3 percent to 5 percent of a
flavor enzyme; the health-care compound fruit and vegetable beverage is prepared through the steps of treating the raw materials, carrying out enzymolysis, blending, sterilizing and the like. The beverage provided by the invention has the most scientific and reasonable
raw material formula and maintains a natural fruit and vegetable
flavor; the beverage is fresh and mellow, is sour, sweet and palatable and is high in
nutrient value and long in
shelf life; the health-care compound fruit and vegetable beverage has various health-care effects of clearing heat and removing
toxicity, promoting the
secretion of
saliva or
body fluid to quench
thirst, nourishing
stomach and
spleen, detoxifying and maintaining beauty, dispelling cold and the like.
