Liquid marbles are water droplets covered with solid particles. Here we show a method for the preparation of edible liquid marbles and capsules covered with fatty acid crystals and triacylglycerol crystals. We prepared liquid marbles using a simple method; namely, a water droplet was rolled on lipid crystals in petri dishes. The resulting marbles were converted to capsules covered with a lipid shell by heating. These marbles were stable not only on glass surfaces but also on water surfaces because they had rigid hydrophobic exteriors. The lifetime of the liquid marbles on water depended on the alkyl chain length of the lipid molecules and the pH of the water. These findings are useful for applying liquid marbles to food, cosmetic, and medical products.
液滴弹是覆盖有固体颗粒的水滴。在此，我们展示了一种制备可食用液滴弹以及覆盖有脂肪酸晶体和三酰甘油晶体的胶囊的方法。我们采用一种简单的方法制备液滴弹；即，将水滴在培养皿中的脂质晶体上滚动。通过加热，所得的液滴弹可转化为覆盖有脂质外壳的胶囊。这些液滴弹不仅在玻璃表面稳定，在水面上也稳定，因为它们具有刚性的疏水外部。液滴弹在水面上的寿命取决于脂质分子的烷基链长度和水的pH值。这些发现对于将液滴弹应用于食品、化妆品和医疗产品很有用。
