Abstract:In order to develop a kind of instant wasabi sunflower moss，the optimum formula of instant mountain sunflower moss was developed by orthogonal experiment，and the disinfection treatment method of the earlystage material of instant wasabi sunflower moss was determined through comparative experiment. The experimental results showed that the spiciness and brittleness of instant wasabi sunflower moss were significantly affected by citric acid，acid calcium pyrophosphate and isomaltose.The preliminary disinfection treatment of the material had no effect on the spiciness and brittleness of the instant wasabi sunflower moss，and had a great impact on the shelf life. The optimal formula of instant wasabi sunflower moss was 8 g of isomaltose，1.2 g of citric acid and 0.35 g of acid calcium pyrophosphate. The material was disinfected by ultraviolet and tea polyphenol combined sterilization，which effectively improved the sterilization effect and extended the shelf life of instant wasabi sunflower moss.
