Bitter gourd juice and making method thereof

Abstract

The invention discloses a making method of bitter gourd juice, comprising the steps of separating bitter gourd pulp, aril and bitter gourd seeds; adding water to the bitter gourd pulp and aril, stirring with a stirring unit, adding pectinase before standing, and suction filtering by vacuum to obtain filter residue and filtrate; adding water and yeast to the filter residue for fermentation, and filtering to obtain fermented liquid; drying and crushing the bitter gourd seeds, soaking with lemon juice, and filtering with gauze to obtain bitter gourd seed lemon juice; mixing the filtrate, the fermented liquid and the bitter gourd seed lemon juice, adding rock candy for fermenting, filtering with hollow fiber ultrafiltration membrane, and sterilizing instantaneously at high temperature to obtain the bitter gourd juice; the making method is simple and easy to perform; by making the bitter gourd juice at low temperature, it is possible to reduce loss of nutrients in the bitter gourd during making and maximally retain the nutrients in the bitter gourd; by fermenting with the yeast, it is possible to decompose macromolecules into small molecules, it is easy for a human body to absorb and utilize, and the aril and seeds of the bitter gourd are made effectively use.
