摘要： 柿子营养丰富，但食用后其鞣酸会与许多物质反应并可能危害健康，这一风险在日常生活中常被忽视。因此，本科普实验选用柿子、茶叶、牛奶、豆浆、鸡蛋和香醋等常见食材，结合鞣酸的化学性质，精心设计了适合全年龄段的互动展示方案。旨在以生动有趣的方式传递化学之美，纠正公众食用误区，提升健康安全意识和科学素养。

Abstract: While persimmons offer substantial nutritional value, their tannic acid content can interact with various substances upon ingestion, potentially posing health risks that are frequently overlooked in daily consumption. This popular science experiment selects common dietary items including persimmons, tea, milk, soy milk, eggs, and rice vinegar. By leveraging the chemical properties of tannic acid, we have developed an interactive demonstration framework suitable for participants of all ages. The initiative seeks to vividly convey the beauty of chemistry through engaging methodologies, address prevalent dietary misconceptions, and ultimately enhance public awareness regarding health and safety as well as scientific literacy.
