近日，话题“蓝莓肚脐眼里的霉菌”冲上热搜。

网友：“原来蓝莓这个地方这么脏！”“难怪蓝莓通便……合着我是吃坏肚子了啊。” 有人还分享了用棉签清洗蓝莓的方法，吃之前一定要记得检查。

A viral social media discussion in China has raised alarms over potential mold growth in the calyx of blueberries — a small indentation humorously nicknamed the fruit's "belly button." Netizens shared cleaning hacks and debating whether the issue stems from hygiene oversights or natural fruit characteristics. Many recommended using cotton swabs to clean the calyx area before consumption.

蓝莓营养丰富，被誉为“浆果之王”，同时因为它含有大量的花青素也被大家称之为“护眼之星”。但是，蓝莓果蒂处的凹陷部位（俗称“肚脐眼”）因结构特殊，容易积聚水分和残留物，成为霉菌滋生的高风险区域。

Known as the "King of Berries", blueberries are prized for their high anthocyanin content, linked to eye health and antioxidant benefits. However, experts note that the calyx's unique structure — a moisture-trapping crevice — makes it prone to residue buildup and mold colonization, particularly in humid or warm conditions.

肉眼判断蓝莓的好坏

正常现象：蓝莓表面的白霜是天然果粉（含花青素），呈白色或淡灰色，无绒毛感，可安全食用。

Safe to eat: A natural whitish-gray "bloom" (a protective layer of fruit — derived wax containing anthocyanins) coating the skin.

霉变特征：果蒂处出现灰绿色、黑色絮状物或绒毛状菌丝，伴随异味，即表明已霉变。

Discard if: The calyx shows gray-green or black fuzzy patches, emits a musty odor, or exhibits visible fungal threads.

蓝莓的选购与储存

新鲜蓝莓表面有一层薄薄的果粉，这是蓝莓自身分泌的糖醇类物质，能保护果实，减少水分蒸发，抵御病菌入侵，果粉完整说明蓝莓较新鲜。购买时，注意挑选果实软硬适中，无腐烂、发霉、异味的蓝莓。

Fresh blueberries are coated with a thin, natural layer called the "bloom" — a powdery substance secreted by the fruit itself. Composed of sugar alcohols, this protective coating helps reduce water evaporation, repel pathogens, and maintain freshness. An intact bloom indicates higher freshness. 

挑选要点：选择果粒饱满、表皮无褶皱、果蒂呈嫩绿色且干燥的蓝莓。若果蒂发黑、干瘪，则表明蓝莓已不新鲜。

Buying tips: When purchasing, select berries that are firm (neither too hard nor too soft), free of rot, mold, or unusual odors.

存储技巧：购买后，如需储存，可将蓝莓放入保鲜盒或带孔的容器中，进行低温或冷藏保存。新鲜蓝莓保质期较短，建议一次不要购买太多。

Storage tips: Refrigerate in breathable containers; consume within days due to rapid spoilage.

清洗方法：食用前，用流动的清水认真冲洗，并尽快食用，避免长时间放置。

Cleaning tips: Rinse gently under running water just before eating.

风险提示：蓝莓霉变速度较快，尤其在潮湿、高温环境中。购买后应尽快食用，避免长时间常温存放。

食用蓝莓的注意事项

过量食用蓝莓可能引发反酸、腹痛、腹泻、消化不良等胃肠道问题。此外，部分人群可能对蓝莓过敏，如有相关过敏情况应避免食用。

由于蓝莓中含有一定量的糖、果酸等物质，高血糖、易腹泻人群应注意控制食用量。若正在服用特殊药物，建议咨询医生后再决定是否食用。

蓝莓具有诸多益处，但“吃蓝莓护眼、防老年痴呆、能延年益寿”属于夸大宣传，消费者需仔细辨别，避免上当受骗。

While nutrient-dense, overconsumption may trigger gastrointestinal discomfort, including diarrhea or acid reflux. Diabetics and those prone to digestive issues are advised to moderate intake. Claims that blueberries can "prevent dementia" or "extend lifespan" lack robust scientific backing and are often exaggerated in marketing. Consumers are urged to critically evaluate such assertions and prioritize evidence-based health guidance.
