“…Furthermore, complex crosslinking was formed via the Maillard reaction in the presence of glucose in the chitosan or CC films after hot air drying. The initial products of the Maillard reaction are Schiff bases, which rearrange to form Amadori products, which then undergo further reactions to form irreversible advanced glycation end products, melanoidins and heterogeneous brown polymers with a high molecular weight 38,39,48 . To confirm the crosslinking, the film water solubility was measured (see Table 1).…”

“…showed significantly low water solubility compared to pure chitosan films, revealing that the films were crosslinked through the Maillard reaction. 39,48 The higher glucose content (CSG5) led to the lower solubility, indicating that the crosslink extent increased with glucose content. For CCG1, its solubility was slightly greater than that of CSG1, because β-CD was grafted onto chitosan, causing reduction of free amino groups, leading to lower crosslink extent.…”

“…When heated, glucose was a strong reducing agent that could reduce dye without the use of an alkaline catalyst 37 . Furthermore, glucose was used as a crosslinking agent for the chitosan amino groups induced by heating through the Maillard reaction 38,39 . Besides the presence of β‐CD, montmorillonite (MMT), a natural clay mineral in the smectite group, which is negatively charged within its internal layers, was added to improve colour fastness 40 .…”

Oxygen is an important factor in food deterioration; thus, packaging, with an in-built oxygen indicator, has been widely developed. Here, a safer, natural product-based, colorimetric oxygen indicator film based on β-cyclodextrin grafted chitosan/montmorillonite with methylene blue/glucose system was fabricated.Methylene blue in the activated films was reduced to leuco-form (colourless) by glucose and reverted to blue with oxygen exposure. Glucose, as well as the reducing agent for methylene blue, crosslinked the chitosan. In addition, the grafting of β-cyclodextrin onto chitosan and the addition of montmorillonite as well as humidity led to the faster colour changes of the films. The colour recovery of films could delay by covering them with a poly(ethylene terephthalate) (PET) film. The activated films showed good storage stability at low temperature which is suitable for the package of refrigerated food products. The films had the potential to be used as natural-based colorimetric oxygen indicators for food packaging.

Bone defects are a common clinical issue, but therapeutic efficiency can be challenging in cases of more considerable traumas or elderly patients with degenerated physiological metabolism. To address this issue, a more suitable cell‐biomaterial construct promoting bone regeneration has been extensively investigated, with the chitosan scaffold being considered a potential candidate. In this study, chitosan was crosslinked with different doses of glucose (CTS‐10~50%Glc) using a modified Maillard reaction condition to develop a more appropriate cell‐biomaterial construct. Mouse MC3T3‐E1 pre‐osteoblasts were seeded onto the scaffolds to examine their osteoinductive capability. The results showed that CTS‐Glc scaffolds with higher glucose contents effectively improved the adhesion and survival of mouse MC3T3‐E1 pre‐osteoblasts and promoted their differentiation and mineralization. It was further demonstrated that the membrane integrin α5 subunit of pre‐osteoblasts is the primary adhesion molecule that communicates with CTS‐Glc scaffolds. After that, Akt signaling was activated, and then bone morphogenetic protein 4 was secreted to initiate the osteoinduction of pre‐osteoblasts. The prepared CTS‐Glc scaffold, with enhanced osteoinduction capability and detailed mechanism elucidations, offers a promising candidate material for advancing bone tissue engineering and clinical regenerative medicine. As a result, this study presents a potential tool for future clinical treatment of bone defects.
