摘要：

Herein, an antioxidant, antibacterial and pH-sensitive multifunctional film is fabricated by incorporating anthocyanins-rich purple sweet potato extract and quercetin-loaded chitosan nanoparticles in agar /sodium alginate polymer matrix for monitoring and maintaining the freshness of shrimp. The film shows distinguishable color changes as pH changes and is highly sensitive to volatile ammonia. Moreover, the digital color information of the film is obtained by smartphone combined with RGB (red/green/blue) analysis. The G/R values are successfully used for the evaluation of shrimp freshness. Mor...
