Liquid marbles (LMs) are millimeter-sized liquid droplets in a gaseous phase coated with solid particles. The LM technology allows liquid droplets to be treated as solid particles. As an LM stabilizer, edible particles are of particular interest, especially for applications in the food industry. However and surprisingly, there are limited numbers of reports describing LMs stabilized with edible particles. In this study, we utilize silver dragees, which are millimeter-sized spherical sugar beads coated by silver overlayers used for decorating cakes and cookies, as edible particles to stabilize LMs. The silver dragees surface was modified using stearic acid to work as an effective LM stabilizer by adsorbing at the gas-liquid interface. LMs with millimeter and centimeter sizes can be fabricated. Due to high adsorption energy and jamming effect of the modified dragees at gas-liquid interface, LMs with non-equilibrium shapes including intricate ones with varying curvatures can be prepared. Developing LMs with customizable shapes is crucial for expanding their potential applications and versatility as functional systems for food applications. We therefore show how these customizable-shaped LMs can be utilized as an edible decoration material for food applications.
液滴弹（LMs）是包裹着固体颗粒的毫米级气相液滴。液滴弹技术能将液滴当作固体颗粒来处理。作为一种液滴弹稳定剂，可食用颗粒尤其受关注，特别是在食品工业中的应用。然而，令人惊讶的是，描述用可食用颗粒稳定液滴弹的报告数量有限。在本研究中，我们使用银珠糖作为可食用颗粒来稳定液滴弹，银珠糖是包裹着用于装饰蛋糕和饼干的银层的毫米级球形糖珠。通过用硬脂酸对银珠糖表面进行改性，使其通过在气液界面吸附而成为有效的液滴弹稳定剂。可以制备毫米和厘米尺寸的液滴弹。由于改性糖珠在气液界面具有高吸附能和堵塞效应，因此可以制备具有非平衡形状（包括具有不同曲率的复杂形状）的液滴弹。开发具有可定制形状的液滴弹对于扩大其作为食品应用功能系统的潜在应用和多功能性至关重要。因此，我们展示了这些可定制形状的液滴弹如何用作食品应用的可食用装饰材料。
