盒马网购虾煮熟后出现蓝色液体？专家解读三种可能

Core Viewpoint - The incident involving blue particles found in cooked shrimp purchased from Hema raises concerns about food safety, prompting a consumer to seek further testing despite the company's assurances regarding the product's safety [1][2]. Group 1: Incident Details - A consumer, Ms. Wang, discovered blue particles in a cooked shrimp and contacted Hema's customer service, which attributed the discoloration to factors related to the shrimp's farming environment, claiming it does not affect edibility [1]. - Ms. Wang has retained a sample of the shrimp for testing and Hema has promised to cover costs and follow up if any safety issues are detected [2]. Group 2: Expert Analysis - According to food safety expert Wang Silu, there are three potential reasons for the blue discoloration in cooked shrimp: 1. Related to hemocyanin, where copper ions may not fully detach during cooking, leading to the formation of blue shrimp proteins, which are generally safe to eat [4]. 2. Associated with algae, where high levels of blue-green algae consumed by the shrimp may leave residual blue color, which can be removed by rinsing [4]. 3. Linked to fluorescent bacterial contamination, which is rare and typically accompanied by foul odors and slime, indicating spoilage [4]. - Overall, the most likely cause of the blue color is the oxidation of hemocyanin, which does not pose a safety risk and does not significantly affect the shrimp's nutritional value [5].
