The invention discloses a preparation method of
banana powder with good rehydration characteristic and being not easy to
agglomerate. The method makes banana
flesh into the
banana powder through procedures of color protection, thermal sterilization, controllable
enzymatic hydrolysis technology, preparation, high speed shearing emulsification, secondary homogenization,
high pressure spraying and
drying,
package with air-flow
racking machine, and so on. Color protection with
sodium bisulfite solution is carried out to the banana promptly after being peeled off
skin, sterilization is made with hot water, then preparation is made by adding into VC,
citric acid and
water based on proportion, jordaning is carried out with a
colloid mill after pulping,
enzymatic hydrolysis is carried out with pectase, amylum, Beta-cyclodextrine, powdered
sugar and water are carried out for a secondary preparation and a secondary homogenization, finally the
banana powder is sprayed, dried and packed with aluminum-plastic promptly after being cooled. During the preparation process of the banana
powder, no other filling agent is added except color protection agent and dispersant. The banana
powder is characterized by good color, fluidity and rehydration characteristic, being easy to be stored and transported, etc.
