    • Provided are compositions comprising a collection of coated particles, wherein the coated particles comprises an active ingredient dispersed in an resin matrix; and a coating comprising at least one hydrophobic compound. Also provided are methods for preparing compositions comprising: (a) blending an active ingredient (for example, 1-MCP complex powder) with resin at the temperature slightly over the melting point of the resin; (b) dispersing the blend into an oil medium containing hydrophobic particles by shearing and obtain an oil dispersion; and (c) consolidating the resin particles by cooling. Thus, the active ingredient (for example, 1 -MCP complex powder) is imbedded in the resin matrix spheres, and the hydrophobic particles, which also serve as Pickering emulsifier to stabilize the matrix spheres, form a coating layer around the matrix spheres to provide protection against water. Thus, the sphere is composed of the "Pickering" particle and resin matrix, in which the active ingredient is imbedded.
    • 提供的是包含涂覆颗粒的集合的组合物,其中涂覆的颗粒包含分散在树脂基质中的活性成分; 和包含至少一种疏水化合物的涂层。 还提供了制备组合物的方法,其包括:(a)在略高于树脂熔点的温度下将活性成分(例如1-MCP复合粉末)与树脂混合; (b)通过剪切将共混物分散到含有疏水性颗粒的油介质中并获得油分散体; 和(c)通过冷却固化树脂颗粒。 因此,将活性成分(例如,1-MCP复合粉末)嵌入树脂基质球体中,并且还用作Pickering乳化剂以稳定基质球体的疏水性颗粒在基质球体周围形成涂层,以提供 防水。 因此,球体由“Pickering”颗粒和树脂基体组成,其中嵌入活性成分。
