The is recognized all over the world as one of the best almond varieties. It is cultivated in a small area inside the provinces of Siracusa and Ragusa (Sicily, southern Italy). It is used in traditional Sicilian cuisine for both salty and sweet foods and of course in artisan pastry, apart from being consumed as a fruit. Due to its extraordinary organoleptic and beneficial features, the is frequently counterfeit with almond varieties of lower quality coming from other countries. While its nutraceutical features have been studied, the possibility of authenticating it with respect to other varieties has not been explored. In this work, we used microelements determined with ICP-OES and ICP-MS as chemical descriptors to distinguish samples of almonds from almonds coming from California and Spain, which are usually employed as substitutes in pastry. Among the different elements determined, Mn and P were found to be the best descriptors for authentication.
该品种在全世界被公认为是最好的杏仁品种之一。它种植于锡拉库萨省和拉古萨省（意大利南部西西里岛）内的一小块区域。除了作为水果食用外，它还被用于西西里传统美食中的咸味和甜味食品，当然也用于手工糕点制作。由于其非凡的感官特性和有益特征，该品种经常被来自其他国家的低质量杏仁品种假冒。虽然其营养特性已得到研究，但尚未探索将其与其他品种进行鉴别的可能性。在这项工作中，我们使用通过电感耦合等离子体发射光谱法（ICP - OES）和电感耦合等离子体质谱法（ICP - MS）测定的微量元素作为化学描述符，以区分该品种杏仁与通常在糕点中用作替代品的来自加利福尼亚和西班牙的杏仁样品。在所测定的不同元素中，锰（Mn）和磷（P）被发现是用于鉴别的最佳描述符。
