老年人的体味是真的么?
Yes. But there’s also a distinctive middle-aged-person smell and a young-person smell, according to a recent study. The research found that older people have a less intense—and more pleasant—scent than the middle-aged folk and young whippersnappers. Not what you expected, right?
是真的,但近期研究表明中年人和年轻人身上的味道也是有区别的。调查发现相对中年人和青年人来说,老年人的体味不那么强烈,反而相对温和。和你想的不一样吧?
Why does room-temperature coffee taste so bad?
常温的咖啡为何这么难喝?
The temperature affects flavor. Researchers in Belgium found that certain taste bud receptors are most sensitive to food molecules that are at or just above room temperature. So hot coffee may seem less bitter (and, in turn, taste better) because our bitter-detecting taste buds aren’t as sensitive when coffee is hot. Odors influence flavor as well, so even the most bitter hot coffee may taste delicious because of its pleasant aroma; room-temperature coffee doesn’t smell the same.
温度影响口感。比利时的研究者发现,某些味蕾会对处于室温的食物分子更加敏感。由于我们品尝苦味的味蕾在高温度时并不十分敏感,相对而言热咖啡似乎不那么苦啦(当然口感更好)。气味也会影响口感,所以即使是最苦的热咖啡,也会因为它的香气让人觉得美味,而室温咖啡就没这个香气了。
