这项研究调查了泰国商业加工食品中未申报的过敏原，即牛奶、鸡蛋、小麦和花生。在142种商业产品中，发现55例阳性病例（通过定量ELISA方法）含有大于10 ppm的未申报过敏原。在所有阳性产品中，未申报的牛奶出现的频率最高（21例），其次是鸡蛋和小麦（17例），而花生很少发现。牛奶或鸡蛋阳性产品的牛奶蛋白，酪蛋白，或鸡蛋蛋白，卵清蛋白的存在进一步证实，通过蛋白质印迹试验。我们的研究结果应有助于提高泰国食品制造商的意识，需要更仔细的管理过敏性食品成分，并鼓励过敏消费者的过敏原信息的标签，从而减少食物过敏对健康的危害。
This study investigates the presence of undeclared allergens – namely milk, egg, wheat and peanut – in commercial processed food products in Thailand. Out of 142 commercial products, 55 positive cases were found (by quantitative ELISA method) to contain an undeclared allergen greater than 10ppm. Among all positive products, undeclared milk appeared the most frequently (21 cases), followed by egg and wheat with similar frequency (17 cases), while peanut was rarely found. Milk- or egg-positive products were further confirmed by the presence of the milk protein, casein, or the egg protein, ovalbumin, by Western blot test. Our results should help to increase the awareness among Thai food manufacturers of the need for more careful management of allergenic food ingredients, and to encourage the labeling of allergen information for allergic consumers, thus reducing the health hazard from food allergy.
