为什么进口车厘子一个月到中国不坏？买回家没几天就坏了？
双语君约 4 分钟今年车厘子好火，很多人甚至成盒成箱地买。
运输20多天不坏，为何到家容易坏？
车厘子从智利进入中国，海运至少需要23天。它们之所以久放不坏，并不是因为借助了化学物质，而是采取了完善的物理保鲜措施，降低了车厘子的呼吸速率。
Cherries from Chile take at least 23 days to reach China by sea. Their long shelf life is not due to chemical treatments but rather to the use of advanced physical preservation techniques that reduce their respiration rate.
钙，是植物生长所必需的大量元素之一。当果实获得充足的钙供应时，其膨大后的个头会更大，硬度也会显著提高，同时，意味着果实具有更强的抗损伤能力，在运输过程中的磕碰和挤压也不易造成损伤。因此，果农通常会在果实膨大期大量施加钙肥，以此来提高果实的贮藏和运输性能。
After harvesting, cherries undergo pre-cooling to quickly remove field heat. Their core temperature is lowered to around 1°C, reducing pests and respiration rates, which extends freshness.
“休眠”的车厘子被装入1℃左右的集装箱，全程冷链进行运输。
"Dormant" cherries are stored in containers at around 1°C and transported via cold chain.
Once they reach retail and the temperature rises, the cherries "wake up," accelerating metabolism and shortening their shelf life.
如何储存更保鲜？
Repacked cherries spoil faster; refrigerate and eat within 2–3 days. For boxed cherries, refrigerate immediately and consume quickly after opening to maintain freshness.
不要过量食用
近日，有网友发文称自己吃了三碗车厘子后，出现拉肚子、呕吐等症状。医生表示，车厘子富含纤维素，不易消化，尤其对脾胃虚弱的人，一次性吃太多，容易出现上吐下泻类似肠胃炎的症状。如果车厘子不新鲜、发生霉变等，则有可能造成食用者急性肠胃炎。
车厘子性偏温，湿热体质的人也不要多吃，否则易有口干舌燥、口腔溃疡、便秘等上火表现。
不在空腹状态下食用。人在空腹状态下，胃酸浓度较高。车厘子富含果胶质，在胃内与胃酸相结合后，就会变成难于溶解的沉淀物，而刺激胃肠道。
一次性不宜食用过多。《中国居民膳食指南（2022）》建议，每人每天吃水果200克—350克。
Avoid eating cherries on an empty stomach as their pectin reacts with stomach acid, causing irritation.
Don’t eat too many at once—aim for 200–350g of fruit daily, as recommended by the Chinese Dietary Guidelines (2022).
Let cherries warm up after taking them out of the fridge to avoid stomach discomfort from cold fruit.
还有人担心，食用车厘子会导致铁中毒、氰化物中毒。实际上，在正常食用的情况下，中毒发生的概率极低。
