Embodiment 1
[0026] Embodiment 1: a kind of biological fresh-keeping processing method of day lily, it comprises the following steps:
[0027] S1. Material selection: choose fresh day lily, spread it on the steamer, the thickness of the day lily after spreading is 1.5cm;
[0028] S2. Finishing and sterilizing: put the steamer in steam at a temperature of 150°C for 2 minutes, take out the steamer, and cool to room temperature;
[0029] S3. Adding bacteria solution: Add the mixed bacteria solution of Lactobacillus plantarum and Streptococcus lactis to the cooled day lily in a sealed, anaerobic, weakly alkaline environment, and stir for 5 minutes; wherein, the pH of the weakly alkaline environment is 7.5, the concentration of Lactobacillus plantarum in the mixed bacterial solution is 0.1%, the concentration of Streptococcus lactis is 0.2%, and the volume of added bacterial solution per kilogram of day lily is 8ml;
[0030] S4. Storage: put the day lily added with the bacterial solution in st...
