The invention relates to the technical field of
food preparation, in particular to a beverage prepared from a platycodon grandiflorum extract and a preparation method thereof.The platycodon grandiflorum extract beverage is prepared from, by
mass, the platycodon grandiflorum extract, compound
enzyme, a compound stabilizer, a
sweetening agent, a
flavor additive and water. And starting the vacuum freeze dryer to carry out vacuum freeze-
drying treatment on the platycodon root slices, so that the
moisture content of the platycodon root slices is reduced to obtain platycodon root freeze-dried slices, and then crushing and sieving to obtain the platycodon root extract. According to the scheme provided by the invention, the platycodon grandiflorum extract is extracted by adopting a low-temperature vacuum freeze-
drying technology, the platycodon grandiflorum can quickly lose
moisture in a low-temperature freeze-
drying state, but nutritional ingredients of the platycodon grandiflorum cannot be lost due to drying, and particularly, heat-sensitive nutritional ingredients can be greatly reserved; and the platycodon grandiflorum extract for producing the platycodon grandiflorum beverage can maximally keep the original nutritional ingredients from losing.
