Problems solved by technology

However, due to the selection of raw materials with relatively high acidity in the processing of soft drinks, the color of such passion fruit juice is not necessarily the best. In addition, the raw materials will inevitably be damaged in the juice processing, and the impact on the color is particularly serious.
[0004] In addition, passion fruit is currently mainly processed t

Abstract

The invention discloses an extraction method of passion fruit anthocyanin. The extraction method comprises the steps of 1, choosing passion fruit and peel, and drying; 2, screening; 3, smashing; 4, conducting high-pressure extraction on the mixture of the smashed passion fruit and the peel; 5, filtrating; 6, conducting vacuum concentration and drying to obtain passion fruit anthocyanin. According to the extraction method of passion fruit anthocyanin, electric power is used, heat sources of a boiler and the like are not needed, and no waste matter and waste gases of dust, slag and the like are discharged; the solvent is recyclable in the extraction process, and no waste liquor is discharged. The extracted waste residues can also be used as a bioorganic fertilizer, and the extraction method is a fully green manufacturing technology. When passion fruit anthocyanin extracted from the method is applied in passion fruit juice drink, the passion fruit juice drink can be more natural in color, nutritional components can be more fully preserved, and the health care function of the product can be improved; moreover, the passion fruit juice drink has better antioxidation, and shelf life can be prolonged.

Description
