Chinese toon has unique flavor and rich nutrition,but it has a short feeding period and is easy to deteriorate during storage.In order to prolong the storage period of Chinese toon sprouts,a simple,fast and nutritious preservation method was established on the basis of blanching and quick-freezing.On the basis of single factor test,sensory score was used as the evaluation index,and physicochemical analysis was used to optimize.It was compared with four common storage methods of Chinese toon sprouts(bag storage,fresh-keeping agent storage,salt curing storage,blanching and quick-freezing storage).The results showed that the Chinese toon sprouts were blanched in boiling water for 45-60 s within 6 h after picking,cooled with water at 10℃,drained and vacuumed in a storage bag,and stored at-18℃.The characteristic flavor could be effectively maintained without significant loss of nutrient content,and the food safety index met the standard GB 2762-2022.Compared with the four commonly used methods for storage and preservation of Chinese toon,this method had better retention of nutrients and lower nitrite content,and was a suitable method for preservation of Chinese toon resources.
