Double-Crosslinked Biopolymer-Based Hydrogel for Intelligent Food Packaging |
| 초록 |
A facile approach is proposed for the fabrication of nitrogen sensitive hydrogels composed of chemically and physically dual-crosslinked TEMPO-oxidized cellulose nanofibers (TEMPO-CNFs). The hydroxyl groups of TEMPO-CNF suspensions were initially crosslinked chemically with epichlorohydrin (ECH), and subsequently crosslinked physically via the strong electrostatic interaction between carboxylate and Ca2+ ions. Then, anthocyanin is successfully conjugated onto the TEMPO-CNF in hydrogel. The colorimetric hydrogels presented visible color changes over time due to a variety of basic volatile amines known as total volatile basic nitrogen (TVB-N). Furthermore, it was found that the optimized TEMPO-CNF films exhibit a good transmittance and good mechanical strength. The resulting interpenetrated polymer network hydrogel could be promising candidate not only to guarantee food freshness but also preventing food spoilage and food-borne diseases. |
