保温杯可以装咖啡吗
保温杯可以装咖啡。但是不建议。
不建议用保温杯装咖啡，因为保温杯装咖啡保温杯的材料可能会和咖啡里面的物质发生化学反应，而且咖啡放在保温杯后会影响口感。
有些保温杯是可以装咖啡的，有些材质是不能装咖啡的，比如不锈钢保温杯就不能装咖啡。因为咖啡中有一种物质叫单宁酸，单宁酸在不锈钢保温杯中会发生反应，造成保温杯的损伤，也有可能会产生化学作用从而危害健康。
保温杯不能装的东西
1、酸性饮品保温杯一般是真空和不锈钢的，这样可以减少热传递以达到保温的目的，不锈钢虽然耐高温，但是不适合存放酸性的饮品比如像是柠檬汁等。
因为柠檬是一种养生佳品，可以帮助我们调节身体的酸碱平衡有不少的人比较喜欢喝柠檬水，但是它不适合在保温杯中存放，它会将保温杯中重金属物质析出对身体造成伤害。
2、奶制品像牛奶这种饮品打开后应该及时的喝掉或者是在比较低温的环境下保存，如果是在普通环境中或者是放在保温杯里细菌繁殖的速度会加快。
咖啡可以放保温杯吗
咖啡不可以放保温杯。
因为保温杯不锈钢材质的，有耐腐蚀耐腐蚀的特性，但是在如果装盛装酸性饮品的时候就会对杯壁造成侵蚀，甚至发生奇怪的气味，而且咖啡中含有一种叫单宁酸的成分可以与保温杯的杯壁发生化学反应，散发出难闻的气味，导致保温杯变得发黄难洗，所以市售多数的保温杯其实都不太适合装载咖啡之类的饮料，大家可一定要注意。
保温杯使用注意事项
1、热饮时，谨防烫伤。
2、请勿必放在小孩子接触不到的地方，以免烫伤。
3、切勿将杯子直接火上加热，以免塑胶部分造成变形。
4、切勿盛装碳酸饮料饮品或易腐坏的牛乳类食品。
5、切勿置于洗碗机里清洗。
6、切勿用尖锐的金属器具碰撞杯身，以免破坏断热构造，影响保温效果。
