Oysters are rich in nutrients and can be cultivated in oceans; therefore they have attracted considerable interest as a food source. In this study, we investigated the rapid analysis of multiple minerals in oysters using microwave decomposition combined with inductively coupled plasma atomic emission spectrometry. Because all body parts of oysters other than the shell are edible, we homogenized all the edible parts and used them as samples. Multiple sample masses and acid-digestion formulations (nitric acid only and nitric acid with hydrogen peroxide) were evaluated in a microwave decomposition step using zinc as the target analyte. The levels of calcium, potassium, sodium, and magnesium were also studied. Microwave digestion using nitric acid and hydrogen peroxide yielded slightly higher mineral concentration results than those obtained with nitric acid alone. The mineral composition of oysters varies with the cultivation location and season. With the establishment of an appropriate database, the proposed method for the evaluation of mineral content could be used for rapidly determining the origin of oysters.

牡蛎营养丰富，可以在海洋中种植。因此，它们作为食物来源已经引起了极大的兴趣。在这项研究中，我们调查了微波分解结合电感耦合等离子体原子发射光谱法对牡蛎中多种矿物的快速分析。由于牡蛎除壳以外的所有身体部位都是可食用的，因此我们将所有可食用的部位均质化，然后将它们用作样品。在微波分解步骤中，使用锌作为目标分析物，评估了多种样品质量和酸消化配方（仅硝酸和硝酸和过氧化氢）。还研究了钙，钾，钠和镁的含量。使用硝酸和过氧化氢的微波消解比仅使用硝酸获得的矿物质浓度结果略高。牡蛎的矿物质组成随养殖地点和季节而变化。建立适当的数据库后，所提出的矿物含量评估方法可用于快速确定牡蛎的起源。
