The invention discloses
oyster powder and a preparation method thereof, and belongs to the technical field of seasonings. The preparation method comprises the following steps: selecting fresh and live oysters, cleaning shells, opening the shells, taking meat, washing, mixing the
oyster meat with
purified water, slowly cooking at low temperature, then boiling at high temperature, and filtering to obtain
oyster juice; mixing the oyster juice with
maltodextrin, edible salt, white
sugar,
monosodium glutamate, disodium 5 '-inosinate and disodium 5'-guanylate, and sequentially performing high-temperature sterilization, compound
enzyme enzymolysis and
enzyme deactivation; and conveying the powdery precursor
raw material to a
spray drying tower for
drying (with a spiral
cyclone guide plate and three-stage
temperature control), and performing three-stage discharging after
drying to obtain the oyster
powder. The method solves the problems of insufficient delicate
flavor, poor
solubility and high hygroscopicity of the existing oyster
powder, and the prepared oyster powder is strong in delicate
flavor, good in fluidity and stable in quality, and meets the use and storage requirements of seasonings.
