近日，有消费者反映在盒马购买的熟虾煮熟后呈现异常鲜艳的蓝色，引发对其安全性的担忧。对此，盒马官方回应称，该现象属于正常情况，虾可放心食用。专家解释，虾类在加热过程中，其体内一种名为“虾青素”的天然色素会与蛋白质结合，形成复合物。当蛋白质受热变性后，虾青素被释放，通常会使虾壳呈现红色或橙红色。但在某些特殊品种（如部分深海虾）或特定养殖环境下，虾体可能含有微量铜、锌等金属离子，这些离子与虾青素或其他成分发生反应，可能在加热后呈现出蓝绿色调。这种颜色变化属于物理化学反应，并不意味着虾已变质或含有有害物质。盒马方面表示，所售虾类产品均经过严格质检，符合国家食品安全标准。若消费者对产品颜色存疑，建议保留包装并联系客服，但无需过度担心食用安全。同时提醒，选购海鲜时应关注产品新鲜度、储存条件及保质期，避免因保存不当导致变质。总之，“蓝得吓人”的熟虾虽视觉上令人不安，但只要来源正规、无异味、质地正常，通常可安全食用。
Recently, some consumers reported that cooked shrimp purchased from Freshippo (Hema) turned an unusually vivid blue after boiling, raising concerns about food safety. In response, Freshippo clarified that this phenomenon is normal and the shrimp are safe to eat.Experts explain that during cooking, a natural pigment in shrimp called astaxanthin binds with proteins. When heated, the proteins denature and release astaxanthin, typically turning the shell red or orange-red. However, in certain shrimp varieties—especially deep-sea species—or under specific farming conditions, trace amounts of metal ions like copper or zinc may be present. These ions can react with astaxanthin or other compounds during heating, resulting in a bluish or greenish hue. This color change is a harmless physicochemical reaction and does not indicate spoilage or contamination.Freshippo stated that all its shrimp products undergo rigorous quality inspections and comply with national food safety standards. While customers are encouraged to contact customer service if they have concerns—especially with product packaging retained—they need not worry about safety if the shrimp smell and feel normal. The company also reminds shoppers to pay attention to freshness, storage conditions, and expiration dates when buying seafood.In summary, although vividly blue cooked shrimp may look alarming, they are generally safe to consume as long as they come from reputable sources and show no signs of spoilage.
