Abstract

The present invention discloses a preparation method of freeze-dried passion fruits. Mature and non-rotten passion fruits are used as a raw material, and washing, cutting, pulp digging, boiling in alkaline water, epicarp peeling off, color-protecting, sugar-soaking, fruit juice filling, freeze-drying, packaging, etc. are conduced to obtain a finished product. The method of boiling in alkaline water and cold water spraying is used to easily and effectively remove hard epicarp of passion fruit surfaces, a short time is taken and little loss of nutrients in fruit peels is caused, and besides, thevacuum freeze-drying technology is used to process the passion fruit peels to prepare the freeze-dried fruits, and keeps appearance shape, flavor and nutrients of the passion fruits. The prepared freeze-dried product is bright in color, crisp in texture, sour, sweet, tasty, rich in nutrients, in line with tastes of a majority of customers and free of any food additives such as preservatives and other pigments, and has a significant market competitive advantage.
