食用昆虫作为传统动物产品的蛋白质替代品越来越受欢迎。因此,有关其元素组成的信息对于确保人类食用安全非常重要。本文介绍了一种快速、同时测定19种元素的可靠方法(铝,As,B,Ba,Ca,Cd,Co,Cr,Cu,Fe,K,Mg,Mn,Mo,Na,Pb,Se,Sr,和Zn)在密闭容器微波消解后通过电感耦合等离子体质谱法(ICP-MS)在可食用昆虫中。使用三种昆虫认证的参考材料对该方法进行了验证,即黑色士兵苍蝇幼虫餐(BFLY-1),板球面粉(KRIK-1),和粉虫粉(VORM-1)。该方法用于分析12种不同的(全)昆虫。计算每个样品的最大量,Cd,和铅相对于由粮食及农业组织/世界卫生组织确定的其临时可容忍的每日摄入量值。大部分样本,除了蝎子和狼羚羊,大剂量食用是安全的(每天1000-10,000只昆虫)。此外,大多数样品含有高水平的铁,K,Na,Zn,提供这些新型蛋白质替代品的营养概况的初步概述。
Edible insects are becoming increasingly popular as protein alternatives to traditional animal-based products. As such, information on their elemental composition is important to ensure they are safe for human consumption. This article describes the development and validation of a rapid, reliable method for the simultaneous determination of 19 elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Pb, Se, Sr, and Zn) in edible insects by inductively coupled plasma mass spectrometry (ICP-MS) following closed vessel microwave digestion. The method was validated using three insect certified reference materials, namely black soldier fly larvae meal (BFLY-1), cricket flour (KRIK-1), and mealworm powder (VORM-1). The method was applied to analyze twelve different (whole) insect species. The maximum amount of each sample was calculated for As, Cd, and Pb with respect to their provisional tolerable daily intake values established by the Food and Agricultural Organization/World Health Organization. Most of the samples, except for scorpions and tarantulas, were safe to consume at large doses (1000-10,000 insects per day). Furthermore, most of the samples contained high levels of Fe, K, Na, and Zn, providing a preliminary overview of the nutritional profile of these novel protein alternatives.
