Problems solved by technology

The fruit juice produced by this method generally has the following disadvantages: more nutrients, especially vitamins, are lost, the flavor of the fruit is changed to a large extent, and the fresh taste of the fruit is lost.
Chlorine-containing disinfectants rely on the characteristics of pH value, which may easily cause problems of unstable bactericidal effect and residual chlorine in the actual operation process
These problems will bring food safety hazards to subsequent processing and may bring chlorine into the final product, causing product contamination

Abstract

The invention discloses frozen juice containing passion fruit-blueberry mixed pulp and a preparation method thereof. The method comprises the following steps of: grading passion fruit and blueberry, selecting and cleaning; disinfecting with dibromohydantoin; blanching at the temperature 90-95 DEG C for 30 seconds; peeling the fruits, dicing or digging pulp; instantly freezing to 30 DEG C below zero in an instant freezer and preparing mixed pulp; mixing the mixed pulp with mixed syrup which is prepared from high fructose syrup, isomaltulose syrup, composite phosphate, complex organic acid and purified water; and inspecting and performing split charging to obtain a finished product. The invention has the advantages: nutritional ingredients of fruits, particularly dietary fiber and vitamin C are kept to the maximum extent, the mouthfeel of fresh fruits is kept, comprehensive and balanced nutrition is realized by scientific mixing, the juice undergoes enzymatic browning difficultly, and large-amplitude fluctuation of blood sugar is not caused easily.

Description

technical field [0001] The invention relates to fruit juice, in particular to a frozen fruit juice containing mixed pulp of passion fruit and blueberry and a preparation method thereof. Background technique [0002] At present, the traditional processing methods of fruit juice are produced through processing techniques such as juicing, concentration, and high-temperature sterilization. The fruit juices produced by this method generally have the following disadvantages: more nutrients, especially vitamins, are lost, the flavor of the fruit is changed to a large extent, and the fresh taste of the fruit is lost.
