Abstract

The invention discloses a preparation method of dried mangoes. The preparation method comprises the steps of removing rotten mangoes and impurities from mangoes, cleaning the mangoes with saline water, removing skins and kernels of the mangoes, slicing regularly, performing color protection on the sliced mangoes, pickling with sugar, putting in a tray in a microwave drying device for microwave drying to remove 55-60% of moisture in the sliced mangoes, quickly freezing with liquid nitrogen, lyophilizing in a tray of a vacuum freezing-drying device for reducing the moisture of the mangoes to be 5-6%, and performing vacuum drying to obtain the dried mangoes. The dried mangoes prepared by adopting the method have the high nutritive value and the good quality.

Description

technical field [0001] The invention relates to the field of food production, in particular to a production method of dried mangoes.
