Methods of generating performic acid by contacting aqueous oxidizing agent and aqueous formic acid source in liquid phase are disclosed. A system and apparatus for the in situ production of the performic acid chemistries is further disclosed. In particular, a continuous flow reactor is provided to generate performic acid at variable rates. Methods of employing the oxidizing biocide for various disinfection applications are also disclosed.

The invention discloses a preservation method for fresh blueberry, and relates to the preservation technique field of blueberry. The preservation method of the invention comprises the following steps: step (1): soaking fresh blueberries in an aqueous sodium alginate solution, taking out and drying; step (2): soaking the fresh blueberries treated in step (1) in an aqueous solution containing ε-PL and N,O carboxymethyl chitosan, taking out and drying; step 3: repeating steps (1)-(2). According to the invention, multilayer edible film is coated on the surface of blueberry, so as to extend the storage period of blueberry, thus avoiding the rot and deterioration of blueberry during storage.
