Health-care preserved durian white flesh and preparation method thereof

Abstract

The present invention discloses a health-care preserved durian white flesh and a preparation method thereof. The preparation method comprises the following steps: (1) fresh durian white fleshes are taken; the taken durian white fleshes are cut into strips or slices with a thickness controlled at 3-5 mm; and the durian white flesh strips or slices are rinsed with deionized water to obtain white flesh meat; (2) the white flesh meat is put into a blanching solution for a blanching treatment; when the blanching solution is cooled to a normal temperature; and the white flesh meat is continuously treated for 2-3 h; (3) the treated white flesh meat after the step (2) is rinsed; the rinsed white flesh meat is drained; and the drained white flesh meat is soaked in a fermentation solution; (4) the fermented durian white flesh meat is taken; the taken fermented durian white flesh meat is washed clean; the washed durian white flesh meat is drained; the drained durian white flesh meat is soaked ina sugar solution; the soaked durian white flesh meat is heated at a vacuum degree of 620-660 mm mercury column; after boiling out, the durian white flesh meat is boiled for 15-25 min; and when the boiled durian white flesh meat is cooled to a normal temperature, then the durian white flesh meat is subjected to sugar soaking for 8-10 h at a normal temperature; (5) the both sides of the treated white flesh meat in the step (4) are dried; the dried white flesh meat is cooled to a normal temperature; and then the cooled white flesh meat is placed in a ventilated place for 8-10 h; and (6) a layer of white sugar powder is evenly sprayed on the re-softened white flesh meat slices to obtain a finished product.
