A strict and lifelong gluten-free diet is the only treatment of celiac disease. Gluten contamination has been frequently reported in nominally gluten-free products. The aim of this study was to test the level of gluten contamination in gluten-free products currently available in the Italian market.
A total of 200 commercially available gluten-free products (including both naturally and certified gluten-free products) were randomly collected from different Italian supermarkets. The gluten content was determined by the R5 ELISA Kit approved by EU regulations.
Gluten level was lower than 10 part per million (ppm) in 173 products (86.5%), between 10 and 20 ppm in 9 (4.5%), and higher than 20 ppm in 18 (9%), respectively. In contaminated foodstuff (gluten > 20 ppm) the amount of gluten was almost exclusively in the range of a very low gluten content. Contaminated products most commonly belonged to oats-, buckwheat-, and lentils-based items. Certified and higher cost gluten-free products were less commonly contaminated by gluten.
Gluten contamination in either naturally or labeled gluten-free products marketed in Italy is nowadays uncommon and usually mild on a quantitative basis. A program of systematic sampling of gluten-free food is needed to promptly disclose at-risk products.
严格且终身的无麸质饮食是乳糜泻的唯一治疗方法。无麸质产品中麸质污染的报道屡见不鲜。本研究旨在检测意大利市场上现有无麸质产品的麸质污染水平。
从意大利不同超市随机收集了200种市售无麸质产品（包括天然无麸质产品和认证无麸质产品）。麸质含量通过欧盟法规批准的R5 ELISA试剂盒测定。
173种产品（86.5%）的麸质水平低于百万分之十（ppm），9种产品（4.5%）在10至20 ppm之间，18种产品（9%）高于20 ppm。在受污染食品（麸质>20 ppm）中，麸质含量几乎完全处于极低麸质含量范围内。受污染产品最常见于燕麦、荞麦和小扁豆类食品。经过认证且成本较高的无麸质产品受麸质污染的情况较少见。
如今，在意大利市场上销售的天然或标明无麸质的产品中，麸质污染并不常见，而且从数量上来说通常较轻。需要开展一项无麸质食品系统抽样计划，以便及时发现有风险的产品。
