The toxicity of the degradation products (DPs) of the ozone-treated AFB<sub>1<\/sub>-Contaminated Corn (ACC) was also evaluated using the human hepatocellular carcinoma cell line (HepG2) as model cells. The degradation rate of AFB<sub>1<\/sub> in corn increases with ozone concentration and treatment time. The results showed that ACC with 13.47% MC was easier to be degraded by ozone than with 20.37% MC. Treated with 90\u00a0mg\u00a0L<sup>\u22121<\/sup> ozone for 20\u00a0min and 40\u00a0min, AFB<sub>1<\/sub> in corn with 13.47% MC decreased from 83\u00a0\u03bcg\u00a0kg<sup>\u22121<\/sup> to 18.12\u00a0\u03bcg\u00a0kg<sup>\u22121<\/sup> and 9.9\u00a0\u03bcg\u00a0kg<sup>\u22121<\/sup>, respectively, well meeting the China National Standard of AFB<sub>1<\/sub> in corn (20\u00a0\u03bcg\u00a0kg<sup>\u22121<\/sup>). In order to evaluate the safety of ozone used on ACC, the impacts of AFB<sub>1<\/sub> as well as untreated and ozone-treated ACC with the same level of AFB<sub>1<\/sub> content on HepG2\u2019s survival rate, morphology, and apoptosis were studied. The results showed that ACC had high cell toxicity while the toxicity of ozone-treated ACC had no significant difference with that of the AFB<sub>1<\/sub>-free culture solution. It is concluded that ozonation can quickly and effectively degrade AFB<sub>1<\/sub> in corn and diminish ACC\u2019s toxicity, and therefore, ozonation is expected to be an effective, fast, and safe method for AFB<sub>1<\/sub> degradation in ACC.<\/p>\n<p>&nbsp;<\/p>\n<p><a title=\"ozone use for aflatoxin reduction\" href=\"http:\/\/ozone-services.com\/ozone-applications\/grain-treatment\/\">Learn more about ozone use for Aflatoxin reduction here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Effect of ozone treatment on aflatoxin B1 and safety evaluation of ozonized corn See original here Authors: Xiaohu Luo, Ren Wang, Li Wang, Yongfu Li, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[19],"tags":[107,108],"class_list":["post-375","post","type-post","status-publish","format-standard","hentry","category-ozone-services-2","tag-aflatoxin-in-corn","tag-aflatoxin-reduction"],"_links":{"self":[{"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/posts\/375","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/comments?post=375"}],"version-history":[{"count":0,"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/posts\/375\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/media?parent=375"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/categories?post=375"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.oxidationtech.com\/blog\/wp-json\/wp\/v2\/tags?post=375"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
