  Ingestible compositions comprising a chromic change agent together with methods of making and using them are provided. The chromic change agent alternatively may be associated with the ingestible, such as a packaging material for the ingestible. In response to a triggering event, physical or chemical, the chromic change agent changes color to provide information as to the history of the ingestible, either prior or contemporaneous with use. Depending on the use, the color change agent may be reversible or irreversible. Various solid or liquid ingestible compositions are provided for determining ingestible temperature, storage temperature, user temperature, light exposure, pH change, hydration or solvation change, mechanical stress, and the like, particularly in comestibles. Of particular interest are polydiacetylene polymers that may be formulated to provide compositions having numerous different color transition triggering mechanisms. The invention is also related to other chromic change agents that may be incorporated into ingestibles.

  提供了包含变色剂的可摄入组合物，以及制造和使用它们的方法。变色剂可以与可摄入物质相关联，例如可摄入物质的包装材料。在触发事件（物理或化学）的响应下，变色剂会改变颜色，以提供有关可摄入物质的历史信息，无论是在使用前还是同时。根据使用情况，颜色变化剂可以是可逆的或不可逆的。提供了各种固体或液体可摄入组合物，用于确定可摄入物质的温度、存储温度、用户温度、光照暴露、pH 值变化、水合或溶解度变化、机械应力等，特别是在食品中。特别感兴趣的是聚二炔基聚合物，可以制成具有许多不同颜色转换触发机制的组合物。本发明还涉及其他可用于可摄入物质的变色剂。
