Research progress in walnut allergens and its detection methods
-
摘要: 核桃为植物坚果类中的主要过敏原之一。如何快速、准确、经济有效地检测核桃过敏原是国外核桃食品安全关注的热点。已知核桃中主要过敏原是Juglans Jug r 1~4、Juglans Jug n 1及Jug n 2共6个,其致敏率较高且可导致严重过敏反应。核桃过敏原主要检测方法有酶联免疫吸附法和PCR法。加强核桃中过敏原及其检测方法的研究,对保障核桃过敏患者安全具有重要意义。Abstract: Walnut is regarded as one of major food allergen in plant nuts.Quick, precise and economical detection of walnut allergen has been a hotspot in food, medical and health industries.It is well known that six proteins Juglans Jug r 14, Juglans Jug n 1 and Jug n 2 are major allergens in walnut, which are characteristic of high allergenicity and can cause severe anaphylactic response.Currently, the main successful applied methods to detect walnut allergens are ELSIA and PCR.Enforcing the research of walnut allergens and their detection methods could provide the theoretical references for the allergen detection in different food sources and the ensure of food safety for human health.
