摘要: 对云南省不同产地美味牛肝菌矿质元素含量及风险进行分析评估,明确矿质元素含量差别及暴露风险,为云南省食用菌产业的发展和野生牛肝菌的食用安全评估提供参考依据。采集云南8 个产地美味牛肝菌171 份样品,利用电感耦合等离子体发射光谱法测定美味牛肝菌中14 种矿质元素含量,结合SPSS统计软件对原始数据进行标准化处理消除量纲,计算主成分分析综合得分并进行相关性分析。结果表明:美味牛肝菌中Ca、Fe、Mg、Na等矿质元素含量丰富,不同产地美味牛肝菌中矿质元素含量具有差异;相关性分析表明子实体中元素之间主要以协同作用为主,部分元素之间存在拮抗作用;有毒元素Cd的富集可能与Fe、Mg、Ba、Co、Cr、Mn、V、Zn存在较好的协同作用。主成分分析综合得分能反映出不同产地美味牛肝菌的元素含量差异,元素的富集可能与诸多生态因子有关。昆明、玉溪、大理、曲靖等地区的美味牛肝菌存在Cd暴露风险,建议消费者适量食用。对美味牛肝菌元素含量特征及相关性进行分析,可为云南省野生牛肝菌资源的开发利用和食用安全性评估提供科学依据。

Abstract: A comparative study was carried to analyze the mineral contents of Boletus edulis from different producing areas in Yunnan province and to evaluate the health risk of dietary exposure to mineral elements by consumption of B. edulis, aiming to provide a basis for the development of the edible fungi industry in the province and food safety evaluation of wild B. edulis. A total of 171 samples of B. edulis were collected from 8 producing areas in Yunnan province. The contents of 14 mineral elements were determined by inductively coupled plasma emission spectrometry (ICP-AES). The original data were standardized with SPSS statistical software to eliminate the dimension, and comprehensive scores from principal component analysis were calculated and correlation analysis was carried out. The results showed that 1) B. edulis was rich in mineral elements such as Ca, Fe, Mg and Na, and there were differences in the content of mineral elements in B. edulis from different habitats; 2) the correlation analysis indicated that the major elements in B. edulis interacted synergistically (there was good synergism of the enrichment of the toxic element Cd with Fe, Mg, Ba, Co, Cr, Mn, V and Zn), and some antagonistically; 3) the comprehensive scores from principal component analysis could reflect the difference in mineral element contents of B. edulis from different areas, and the enrichment of elements may be related to many ecological factors; and 4) there was a health risk associated with dietary exposure to Cd in B. eduli from Kunming, Yuxi, Dali, Qujing and other areas, and it is recommended that consumers should consume an appropriate amount of B. eduli. The mineral element content characteristics of B. edulis and correlation analysis can provide a scientific basis for the exploitation, utilization and food safety evaluation of wild B. edulis in Yunnan.
