Significant wastage of residual liquid food, such as milk, yogurt, and honey, in food containers has attracted great attention. In this work, a bio-inspired edible superhydrophobic interface was fabricated using U.S. Food and Drug Administration-approved and edible honeycomb wax, arabic gum, and gelatin by a simple and low-cost method. The bio-inspired edible superhydrophobic interface showed multiscale structures, which were similar to that of a lotus leaf surface. This bio-inspired edible superhydrophobic interface displayed high contact angles for a variety of liquid foods, and the residue of liquid foods could be effectively reduced using the bio-inspired interface. To improve the adhesive force of the superhydrophobic interface, a flexible edible elastic film was fabricated between the interface and substrate material. After repeated folding and flushing for a long time, the interface still maintained excellent superhydrophobic property. The bio-inspired edible superhydrophobic interface showed good biocompatibility, which may have potential applications as a functional packaging interface material.
大量剩余液体食物（如牛奶、酸奶和蜂蜜）在食品容器中的浪费引起了极大关注。在这项工作中，使用美国食品和药物管理局批准的可食用的蜂窝蜡、阿拉伯胶和明胶，通过一种简单且低成本的方法制备了仿生可食用的超疏水界面。仿生可食用的超疏水界面呈现出类似于荷叶表面的多尺度结构。这种仿生可食用的超疏水界面对各种液体食物表现出高接触角，并且可以有效地减少液体食物的残留。为了提高超疏水界面的粘附力，在界面和基底材料之间制备了柔性的可食用弹性薄膜。经过长时间的反复折叠和冲洗，该界面仍保持出色的超疏水性。仿生可食用的超疏水界面表现出良好的生物相容性，可能有作为功能包装界面材料的潜在应用。
