Lupin is a herbaceous plant from the legume family whose seed allergens usually have cross-reaction with peanut. Lupin flour is used in human nutrition because of its high nutritional and functional qualities.
The aim of this work was to detect non-specified lupin proteins contained in several manufactured foods.
Serum from a patient suffering anaphylactic episodes after ingestion of a certain brand of cookies and with oral allergy syndrome after eating chicken bouillon was used as a tracer. Lupin seeds and commercial food extracts were analyzed by SDS-PAGE, immunoblotting and immunoblotting inhibition. Lupin extract allergenicity after thermal processing was also analyzed.
A lupin allergen with a molecular weight close to 14 kDa was detected in extracts from cookies, a chicken bouillon cube and a chicken dehydrated soup.
The presence of unsuspected, hidden non-specified lupin sources in food labeling was demonstrated. According to the results of this study, it is important for food-allergic patients that food labels should declare all the components irrespective of their quantity.
羽扇豆是豆科的一种草本植物，其种子过敏原通常与花生存在交叉反应。羽扇豆粉因其高营养和功能特性而被用于人类营养。
这项工作的目的是检测几种加工食品中含有的未明确的羽扇豆蛋白。
将一名在摄入某品牌饼干后出现过敏反应且在食用鸡肉汤后患有口腔过敏综合征的患者的血清用作示踪剂。通过SDS-PAGE、免疫印迹和免疫印迹抑制分析羽扇豆种子和商业食品提取物。还分析了热处理后羽扇豆提取物的致敏性。
在饼干、一块鸡肉汤块和鸡肉脱水汤的提取物中检测到一种分子量接近14 kDa的羽扇豆过敏原。
证明了食品标签中存在未被怀疑的、隐藏的未明确羽扇豆来源。根据这项研究的结果，对于食物过敏患者来说，食品标签应声明所有成分，无论其含量多少，这一点很重要。
