Mango (Mangifera indica) is one of the most popular tropical fruits around the world. It is also widely and commonly used in many cuisines and products in the food industry. However, the anaphylactic reaction caused by mango has long been reported as a major problem for consumption in recent years. To prevent allergens in mango, the best way is to avoid mango in the diet. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed for the detection of mango in food. Four specifically designed LAMP primers targeting the internal transcribed sequence 1 (ITS1) of nuclear ribosomal DNA sequence regions were used to address the LAMP reaction for amplifying mango DNA. The results demonstrated that the detection of mango DNA was specifically validated by the LAMP primer. The sensitivity of LAMP for detecting mango DNA is equivalent to that of the traditional PCR method. The LAMP primer sets showed high specificity for detecting the DNA of mango and had no cross-reactions to other species. Moreover, when mango was mixed with other fruits at different ratios, no cross-reactivity for the detection of mango DNA was manifested during LAMP. Finally, genomic DNAs extracted from different heat-processed mangos were used as templates; the detection of mango DNA by LAMP was not significantly affected and was reproducible. As to this established LAMP herein, mango ingredients can be detected, and commercial foods containing mango can also be identified. This assay will be useful and have potential for the rapid detection of mango DNA in practical food markets.

等温核酸扩增法快速,特异性地检测加工食品中的芒果(Mangifera indica)。

芒果(Mangifera indica)是世界上最受欢迎的热带水果之一。它也被广泛并普遍用于食品工业的许多美食和产品中。但是,近年来,芒果引起的过敏反应一直是消费的主要问题。为了防止芒果中的过敏原,最好的方法是避免饮食中的芒果。在这项研究中,开发了一种环介导的等温扩增(LAMP)分析法,用于检测食品中的芒果。靶向核糖体DNA序列区域的内部转录序列1(ITS1)的四种经过特殊设计的LAMP引物用于解决用于扩增芒果DNA的LAMP反应。结果表明,芒果DNA的检测已通过LAMP引物特别验证。LAMP检测芒果DNA的灵敏度与传统PCR方法相当。LAMP引物对检测芒果的DNA具有很高的特异性,并且与其他物种没有交叉反应。此外,当芒果与其他水果以不同比例混合时,在LAMP期间没有发现用于检测芒果DNA的交叉反应。最后,将从不同热处理过的芒果中提取的基因组DNA用作模板。LAMP对芒果DNA的检测没有显着影响,并且具有可重复性。对于本文中建立的LAMP,可以检测到芒果成分,还可以鉴定出包含芒果的商业食品。该测定法将是有用的,并具有在实际食品市场中快速检测芒果DNA的潜力。LAMP引物对检测芒果的DNA具有很高的特异性,并且与其他物种没有交叉反应。此外,当芒果与其他水果以不同比例混合时,在LAMP期间没有发现用于检测芒果DNA的交叉反应。最后,将从不同热处理过的芒果中提取的基因组DNA用作模板。LAMP对芒果DNA的检测没有显着影响,并且具有可重复性。对于本文中建立的LAMP,可以检测到芒果成分,还可以鉴定出包含芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。LAMP引物对检测芒果的DNA具有很高的特异性,并且与其他物种没有交叉反应。此外,当芒果与其他水果以不同比例混合时,在LAMP期间没有发现用于检测芒果DNA的交叉反应。最后,将从不同热处理过的芒果中提取的基因组DNA用作模板。LAMP对芒果DNA的检测没有显着影响,并且具有可重复性。对于本文中建立的LAMP,可以检测到芒果成分,还可以鉴定出包含芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。在LAMP期间没有发现用于检测芒果DNA的交叉反应性。最后,将从不同热处理过的芒果中提取的基因组DNA用作模板。LAMP对芒果DNA的检测没有显着影响,并且具有可重复性。对于本文中建立的LAMP,可以检测到芒果成分,还可以鉴定出包含芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。在LAMP期间没有发现用于检测芒果DNA的交叉反应性。最后,将从不同热处理过的芒果中提取的基因组DNA用作模板。LAMP对芒果DNA的检测没有显着影响,并且具有可重复性。对于本文中建立的LAMP,可以检测到芒果成分,还可以鉴定出包含芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。并且还可以识别出含有芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。并且还可以识别出含有芒果的商业食品。该测定法将是有用的,并且具有在实际食品市场中快速检测芒果DNA的潜力。
