Abstract: The effect of the intelligent active poly(vinyl)alcohol film on the storage quality of Pseudosciaena crocea was studied,and the visible dynamic color changes of the film due to the change of pH value of Pseudosciaena crocea were also discussed. 1% nano-TiO₂ and 3% anthocyanin were incorporated into poly(vinyl)alcohol by solution casting method. The indexes of sensory quality,TBA,total bacteria,volatile base nitrogen and pH,which combined with the changes of difference on film color were used to evaluate the freshness of Pseudosciaen acrocea during 4 ℃ storage. The results showed that the sensory quality,TBA,total bacteria,volatile base nitrogen,and pH values of the PVA-nano-TiO₂-anthocyanin film packaged group were better than those of the unpackaged and pure PVA film packaged groups stored at 4 ℃. The total number of bacteria on the 16th day of storage reached 7.11lg cfu/g for PVA-nano-TiO₂-anthocyanin film packaged group,compared with 7.14lg and 7.03lg cfu/g on the 12th day of storage in other experimental groups. The shelf life was extended 4 d. During the 20 d storage period,the poly(vinyl)alcohol-nano-TiO₂-anthranisin film showed gray-brown(0 d),red-brown(4 d),light red-brown(8 d),incarnadine(12 d),gray(16 d)and dark gray(20 d),which could respond well with the changes of pH values of Pseudosciaena crocea by visible color changes. Therefore,the intelligent poly(vinyl)alcohol packaging film prepared in this study could not only have beneficial effects on the preservation of foods,but also serve as a color indicator to achieve intelligent monitoring in the food storage process.
