Experimental Researches and Analysis on the Formulation of Freeze-Dried Recombinant Fruit

In order to exploit the freeze-dried products suitable for export and rich in nutrition,berry fruits were selected for recombination,and the formula of recombination fruit was screened.Based on the method of sensory evaluation,three kinds of sample with better sensony evaluetion were established.Respectively,they are strawberries:citruses (mass ratio 303.25:100), pitayas:citruses (mass ratio 117.50:100), pitaya:blueberries (mass ratio 179.00:100).VC retention rate of three samples is about 95%.The pitaya-blueberry recombinant fruit is dark.The hardnessis 197.565 N,and the chewability is not good.Finally,freeze-dride fruit sample of strawberry-citrus recombination and pitaya-citrus recombinantion were developed,and the freeze dried technology was analyzed by taking pitaya-citrus recombinantion as an example.
