Embodiment 1
[0028] A nanofiber indicator film for intelligent detection of seawater fish spoilage is prepared by the following steps:
[0029] (1) Add gelatin, nano-chitin, anthocyanin and curcumin successively in the acetic acid aqueous solution of 80% in mass concentration, stir 24h under 42 ℃ of constant temperature conditions and make spinning solution, described gelatin, nano-chitin The addition amount accounts for 7.2% and 1.2% of the mass of the acetic acid aqueous solution respectively; the mass ratio of curcumin and anthocyanin is 2:8;
[0030] (2) The spinning solution is spun into a nanofiber indicator film using an electrospinning machine, wherein the receiving material is aluminum foil paper, and the parameters for spinning by the electrospinning machine are as follows:
[0031] The test temperature is 25°C, the relative humidity is 50%, the injection speed is 0.1mm / h, the distance from the spinning needle to the receiving device is 10cm, and the voltage is set to 25kv;
