The sensory score of the product was 95.5. The physical and chemical properties and microbial indicators of instant seasoning T. ovatus were in line with the relevant standards. The products had the advantages of low salt,low fat and high protein,outstanding flavor,no cooking and ready-to-eat and so on.
