Bio-Based, Flexible, and Tough Material Derived from ε-Poly-l-lysine and Fructose via the Maillard Reaction
[Image: see text] We report a bio-based, soft, elastic, and tough material prepared from a mixture of ε-poly-l-lysine (ε-PL) and d-fructose. The obtained complex was insoluble in water, whereas its ingredients had high water solubility. This complex was likely formed via Schiff base formation and su...

description | [Image: see text] We report a bio-based, soft, elastic, and tough material prepared from a mixture of ε-poly-l-lysine (ε-PL) and d-fructose. The obtained complex was insoluble in water, whereas its ingredients had high water solubility. This complex was likely formed via Schiff base formation and subsequent rearrangement reactions, that is, the Maillard reaction, because the reaction occurred between reducing sugars and cationic polyelectrolytes having primary and secondary amino groups. The progress of the Maillard reaction was investigated by proton nuclear magnetic resonance spectroscopy and Fourier transform infrared spectroscopy. Mechanical properties of the complexes were evaluated by tensile testing, and the properties of the optimized complex [ε-PL/fructose = 60:40 (w/w), maximum stress = 27.9 MPa, strain at break = 46%, Young’s modulus = 741.6 MPa] resembled those of some petroleum-based plastics. Additionally, the ε-PL/fructose complex displayed antimicrobial activity against Bacillus subtilis. These ε-PL/fructose complexes have biological properties such as antimicrobial activity, low toxicity toward mammals, and biodegradability, which are attributable to the intrinsic nature of ε-PL, as well as enhanced mechanical properties and water resistance compared with pure ε-PL. |
