An edible and pH-sensitive film combined with electrochemical writing was developed using gelatin, gellan gum and red radish anthocyanin extract for intelligent food packaging applications. The composite film displays orange red-to-yellow color change over the pH range 2-12. The tensile strength, ductility, and barrier response of the films to UV light and oxygen improved with the increase of red radish anthocyanin concentration. Multicolor patterns were successfully drawn on the film using an electrochemical writing method. The composite films acted as gas sensors which presented visible color changes in the presence of milk and fish spoilage, while the written patterns were well preserved. Accordingly, this composite film with written patterns could be an easy-to-use indicator with great potential for monitoring food spoilage as part of an intelligent packaging system.

“…However, the relatively low stability and bioavailability of anthocyanins are the primary barrier to limit the wide and effective applications [9][10][11], raising up the importance of reducing the degradation of anthocyanins and controlling release. So far, encapsulation [12][13][14][15], composite [16][17][18][19] and group substitution [20][21][22][23][24] are the three main means used for anthocyanin stabilization. Some studies have been carried out on the adsorption of pigments by Fe 3 O 4 [25] and the stabilization of Fe 3+ [26,27].…”

Anthocyanins are a class of antioxidants extracted from plants, with a variety of biochemical and pharmacological properties. However, the wide and effective applications of anthocyanins have been limited by their relatively low stability and bioavailability. In order to expand the application of anthocyanins, Fe 3 O 4 /anthocyanin magnetic biocomposite was fabricated for the storage and release of anthocyanin in this work. The magnetic biocomposite of Fe 3 O 4 magnetic nanoparticle-loaded anthocyanin was prepared through physical intermolecular adsorption or covalent cross-linking. Scanning electron microscopy (SEM), Dynamic light scattering (DLS), Fourier-transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD) and thermal analysis were used to characterize the biocomposite. In addition, the anthocyanin releasing experiments were performed. The optimized condition for the Fe 3 O 4 /anthocyanin magnetic biocomposite preparation was determined to be at 60 • C for 20 h in weak alkaline solution. The smooth surface of biocomposite from SEM suggested that anthocyanin was coated on the surface of the Fe 3 O 4 particles successfully. The average size of the Fe 3 O 4 /anthocyanin magnetic biocomposite was about 222 nm. Under acidic conditions, the magnetic biocomposite solids could be repeatable released anthocyanin, with the same chemical structure as the anthocyanin before compounding. Therefore, anthocyanin can be effectively adsorbed and released by this magnetic biocomposite. Overall, this work shows that Fe 3 O 4 /anthocyanin magnetic biocomposite has great potential for future applications as a drug storage and delivery nanoplatform that is adaptable to medical, food and sensing.

“…28 Importantly, it was found that not only the mechanical properties of gelatin film could be significantly improved by gellan gum, 29 also the gellan gum could enhance the thermal stability of anthocyanins according to a new study. 30 Hence, the gelatin/gellan gum blend is considered a perfered film-forming agent to immobilize anthocyanins.…”
