Abstract

The invention discloses a processing method of a dried yellow kiwi fruit. The processing method comprises steps of peeling off and slicing a raw material, cleaning kiwi pulp through normal temperature processing water added with 0.1% of V, placing the sliced kiwi in a plate after protecting color and cleaning, and quick-freezing the sliced kiwi; soaking the quick-frozen sliced kiwi in 25-30% of deacidified and decolorized apple juice for about 20-24h, wherein ratio of the sliced kiwi to sugar liquid is (1: 2)-(1: 3); placing the soaked sliced kiwi in the plate and drying in a vacuum environment with a vacuum degree less than or equal to -0.09Mpa at 50-60 DEG C until water content is 16-18%; and cooling the dried sliced kiwi to normal temperature, immediately filling nitrogen or deoxidizing and packaging the sliced kiwi in an aluminum foil bag. The processing method disclosed by the invention has the beneficial effects that the processed dried yellow kiwi fruit meets characteristics of a finished product which is nutritive and healthy, natural in raw and auxiliary materials, and green in processing technology, and is applicable to processing of other dried fruits.
