Background

The contamination of food products by mycotoxin particularly trichothecenes is a serious health concern. While several studies investigated the concentration and prevalence of trichothecenes in cereal-based products, a comprehensive meta-analysis is not available.

Scope and approach

The concentration and prevalence of trichothecenes (TCNs) such as deoxynivalenol (DON), nivalenol (NIV), 3-acetyldeoxynivalen, 15-acetyldeoxynivalen, toxins T-2 and HT-2, neosolaniol (NEO), fusarenon-X and 4,15-diacetoxyscirpe in cereal-based food products among databases including Scopus, Web of Science, PubMed and Embase was investigated between 1 January of 1983 and 1 February of 2019 by the aid of a systematic review and meta-analysis prevalence. Among 950 explored articles in the identification stage, 57 articles with 372 samples were included in the current meta-analysis.

Key findings and conclusions

Among all studied TCNs, the concentration of DON in cereal-based products were higher than others, exceptionally in bread samples which fusurenon x was the dominant TCNs. Also, the highest TCNs prevalence was correlated with DON, except for baby and infant foods which had predominantly T-2. The overall rank order based on the concentration and prevalence of TCNs were breakfast cereals > noddle > bread > wheat foods > pasta > infant foods > barley prevalence and prevalence barley > wheat foods > infant foods > pasta > bread > breakfast cereals > noddle, respectively. The outcomes of the present meta-analysis highlighted the demand for further improvements in controlling of TCNs among cereal-based products, besides approaching mitigation techniques in order to reduce the dietary exposure to TCNs via the consumption of cereal-based foods.

系统的审查和荟萃分析，以调查谷类食品中毛虫的浓度和患病率

背景

霉菌毒素特别是毛癣菌毒素对食品的污染是严重的健康问题。尽管有几项研究调查了谷物类产品中毛虫的浓度和流行程度，但尚无全面的荟萃分析。

范围和方法

诸如脱氧雪茄烯（DON），雪茄烯酚（NIV），3-乙酰基脱氧雪茄烯，15-乙酰基脱氧雪茄烯，毒素T-2和HT-2，新茄尼醇（NEO），fusarenon-X和4,15之类的毛孢菌素（TCN）的浓度和患病率在1983年1月1日至2019年2月1日期间，借助系统回顾和荟萃分析，对包括Scopus，Web of Science，PubMed和Embase在内的数据库中谷类食品中的-diacetoxyscirpe进行了调查。在鉴定阶段探索的950篇文章中，当前的荟萃分析包括57篇文章和372个样本。

主要发现和结论

在所有研究的TCN中，谷物类产品中DON的浓度高于其他产品，特别是在面包样品中，fusurenon x是主要的TCN。另外，TCN的最高患病率与DON有关，除了主要为T-2的婴儿和婴儿食品。基于TCN的浓度和流行程度的总体排名顺序分别是早餐谷物>点食品>面包>小麦食品>意大利面>婴儿食品>大麦流行和大麦流行>小麦食品>婴儿食品>意大利面>面包>早餐谷物>点食品。本荟萃分析的结果突出表明，需要进一步改善谷物类产品中TCN的控制，
