一种荷叶精油复合明胶仿生包装膜制备和应用

本发明公开了一种荷叶精油复合明胶仿生包装膜制备和应用，属于食品包装材料领域。本发明通过在明胶膜中加入荷叶精油，有效提高明胶膜的机械性能；荷叶精油以皮克林乳液的形式，可以在膜中实现精油的延缓释放，并赋予薄膜抑菌性和抗氧化活性，延长食品保藏期限；在此基础上，通过对新鲜荷叶表面微观结构的成膜转印，制备得到具有超疏水性、低细菌粘附性的荷叶精油复合明胶仿生包装膜。本发明填充了荷叶精油的应用空白，进一步拓宽了荷叶精油的应用。 The invention discloses preparation and application of a lotus leaf essential oil composite gelatin bionic packaging film, and belongs to the field of food packaging materials. The lotus leaf essential oil is added into the gelatin film, so that the mechanical property of the gelatin film is effectively improved; the lotus leaf essential oil is in the form of Pickering emulsion, so that delayed release of the essential oil can be realized in the film, the film is endowed with antibacterial activity and antioxidant activity, and the food preservation period is prolonged; on the basis, the lotus leaf essential oil composite gelatin bionic packaging film with super-hydrophobicity and low bacterial adhesion is prepared through film-forming transfer printing of a microstructure on the surface of a fresh lotus
