近日，話題“藍莓肚臍眼里的霉菌”沖上熱搜。
網(wǎng)友：“原來藍莓這個地方這么臟！”“難怪藍莓通便……合著我是吃壞肚子了啊?！?有人還分享了用棉簽清洗藍莓的方法，吃之前一定要記得檢查。
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.
藍莓營養(yǎng)豐富，被譽為“漿果之王”，同時因為它含有大量的花青素也被大家稱之為“護眼之星”。但是，藍莓果蒂處的凹陷部位（俗稱“肚臍眼”）因結(jié)構(gòu)特殊，容易積聚水分和殘留物，成為霉菌滋生的高風(fēng)險區(qū)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.
肉眼判斷藍莓的好壞
正?，F(xiàn)象：藍莓表面的白霜是天然果粉（含花青素），呈白色或淡灰色，無絨毛感，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.

霉變特征：果蒂處出現(xiàn)灰綠色、黑色絮狀物或絨毛狀菌絲，伴隨異味，即表明已霉變。
Discard if: The calyx shows gray-green or black fuzzy patches, emits a musty odor, or exhibits visible fungal threads.

藍莓的選購與儲存
新鮮藍莓表面有一層薄薄的果粉，這是藍莓自身分泌的糖醇類物質(zhì)，能保護果實，減少水分蒸發(fā)，抵御病菌入侵，果粉完整說明藍莓較新鮮。購買時，注意挑選果實軟硬適中，無腐爛、發(fā)霉、異味的藍莓。
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.
挑選要點：選擇果粒飽滿、表皮無褶皺、果蒂呈嫩綠色且干燥的藍莓。若果蒂發(fā)黑、干癟，則表明藍莓已不新鮮。
Buying tips: When purchasing, select berries that are firm (neither too hard nor too soft), free of rot, mold, or unusual odors.
存儲技巧：購買后，如需儲存，可將藍莓放入保鮮盒或帶孔的容器中，進行低溫或冷藏保存。新鮮藍莓保質(zhì)期較短，建議一次不要購買太多。
Storage tips: Refrigerate in breathable containers; consume within days due to rapid spoilage.
清洗方法：食用前，用流動的清水認真沖洗，并盡快食用，避免長時間放置。
Cleaning tips: Rinse gently under running water just before eating.
風(fēng)險提示：藍莓霉變速度較快，尤其在潮濕、高溫環(huán)境中。購買后應(yīng)盡快食用，避免長時間常溫存放。
食用藍莓的注意事項
過量食用藍莓可能引發(fā)反酸、腹痛、腹瀉、消化不良等胃腸道問題。此外，部分人群可能對藍莓過敏，如有相關(guān)過敏情況應(yīng)避免食用。
由于藍莓中含有一定量的糖、果酸等物質(zhì)，高血糖、易腹瀉人群應(yīng)注意控制食用量。若正在服用特殊藥物，建議咨詢醫(yī)生后再決定是否食用。
藍莓具有諸多益處，但“吃藍莓護眼、防老年癡呆、能延年益壽”屬于夸大宣傳，消費者需仔細辨別，避免上當(dāng)受騙。
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.
