The invention relates to the field of fruit
processing and discloses acerola cherry fruit
powder and a preparation method thereof. The method comprises the following steps of pulping acerola cherry fruit after preprocessing; adding an acerbity removal liquid into the fruit pulp; stirring; performing
colloid-milling, homogenization and
filtration; taking a first filtrate for standby application; adding
pectinase and
cellulase into first filter residues for
processing; performing
colloid-milling, homogenization and
filtration again to obtain a second filtrate; performing homogenization and vacuum concentration after mixing the filtrates; homogenizing after adding
resistant starch and isomaltooligosacharide into concentrated solution; and then performing
vacuum drying to obtain the acerola cherry fruit
powder. As the acerola cherry fruit
powder and the preparation method thereof introduce technologies for special preprocessing, color protection and complex
enzyme processing, nutritional ingredients, in particular
vitamin C and the like of the acerola cherry fruit are remained; and meanwhile, with the adding and the
vacuum drying of proper auxiliary materials, the powder collection rate of the fruit powder is increased. During the whole technology, no any
food additive such as essence and
sweetening agents and no any auxiliary material are added; and therefore, the acerola cherry fruit powder is all-natural nutritional fruit powder which is good in color and luster and high in solvability, and can be widely applied in the industries of foods, health care products and the like.
