Abstract

The invention provides a passion fruit peel dietary fiber, a passion fruit sauce and a preparation method of the passion fruit peel dietary fiber and passion fruit sauce. The preparation method of thepassion fruit peel dietary fiber comprises the following steps of (1) selection and cleaning, (2) primary drying, (3) primary smashing, (4) extraction, (5) secondary drying and (6) secondary smashing. The preparation method has the advantages that an ethyl alcohol extraction process combining addition of citric acid with ultrasonic is adopted, and more fat-soluble mineral elements, proteins, lipids, pigments and other ingredients in peel are removed during many times of extraction, so that the obtained passion fruit peel dietary fiber is low in impurity content and high in fiber purity; the fruit peel dietary fiber is added into the passion fruit sauce to increase the dietary fiber content in juice, so that the nutrition of the fruit sauce is more comprehensive and plentiful; the added dietary fiber is extracted from the passion fruit peel and is light in color and free from extraneous odour, so that the passion fruit sauce remains original colour, lustre and special flavour of the passion fruit pulp, and is attractive in colour and pleasant in aroma.
