The invention discloses a preparation method of instant oysters with
high color and storage stability. The preparation method comprises the following steps: S1, putting shelled
oyster meat into
clean water for rinsing; s2, soaking the cleaned
oyster meat in a solution containing a color fixative; s3,
blanching and curing the soaked
oyster meat,
fishing out and draining; s4, baking the drained oyster meat until the
moisture content is reduced, and then taking out and cooling; s5, packaging the oyster meat with packaging bags made of a light-proof material; s6, the interior of the
package is subjected to
nitrogen charging treatment; and S7, sterilizing the packaged oyster meat in a high-pressure sterilization pot to obtain a finished product. According to the method, L-
cysteine or D-
sodium erythorbate is adopted for soaking before
blanching,
drying is carried out for the optimal time, then packaging is carried out by adopting light-proof material packaging bags in the packaging link, and finally
nitrogen charging operation is carried out on the packaging bags on the basis of light-proof packaging. Through combination of multiple means and multiple mechanisms, the purpose of low-cost color protection is achieved.
