The invention provides a preparation method of a ready-to-eat baby
squid product. The preparation method comprises a stepped
sterilization process; in a adopted heating and cooling process, water at different temperatures is sprayed to the outside of the flexible
package of the processed baby
squid; and the
sterilization process comprises the specific procedures of sequentially spraying water at the temperature of 70 DEG C for 7 minutes, spraying water at the temperature of 90 DEG C for 4 minutes, spraying water at the temperature of 100 DEG C for 2 minutes, spraying water at the temperature of 121 DEG C for 1 minute, spraying water at the temperature of 90 DEG C for 4 minutes and spraying water at the temperature of 45 DEG C for 10 minutes. The stepped
sterilization process and the spray-type heating and cooling process are adopted in the preparation method of the ready-to-eat baby
squid product. Compared with the prior art, the preparation method has the beneficial effects that by adopting the spray-type heating and cooling process, the feasibility of the stepped sterilization process is ensured, and
energy consumption and
water consumption can be reduced; in addition, the totaltime of the sterilization process is shorter than that of the conventional sterilization process so as to prevent the obtained product from being damaged due to overlong
heating time and high-temperature retaining time.
