While the body uses BAs in small amounts in processes like hormone synthesis, ingesting large amounts of BAs from spoiled food can cause serious health problems. Therefore, it is important to detect BAs during food storage and distribution.<\/h3>\n<p><!--more--><\/p>\n<p>This motivated a team of researchers, including Prof. Sungbaek Seo, Associate Professor of Biomaterials Science at Pusan National University, South Korea, to develop a portable molecular sensor that quickly detects the presence of BAs by changing colours.<\/p>\n<\/div><\/section><br \/>\n<div  class='avia-image-container  av-styling-    avia-builder-el-7  el_after_av_textblock  el_before_av_hr  avia-align-center '  itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\"  ><div class='avia-image-container-inner'><div class='avia-image-overlay-wrap'><img class='avia_image' src='https:\/\/fei-online.com\/wp-content\/uploads\/sites\/4\/2023\/04\/shutterstock_1795949911-scaled-e1681297300951.jpg' alt='' title='Young,Woman,With,Spoiled,Sausage,Near,Open,Refrigerator,In,Kitchen' height=\"533\" width=\"800\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><br \/>\n<div   class='hr hr-default   avia-builder-el-8  el_after_av_image  el_before_av_textblock '><span class='hr-inner ' ><span class='hr-inner-style'><\/span><\/span><\/div><br \/>\n<section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock  '   itemprop=\"text\" ><p>\u201cThe rapid and easy monitoring of deleterious BAs released from spoiled foods could alert us, prevent consumption of spoiled meat, maintain food quality, and establish further effective food storage and distribution conditions in the logistic chain,\u201d notes Prof. Seo.<\/p>\n<p>The researchers have detailed this novel development in a recent article published in Food Chemistry [1]. The team combined the distinct colour-changing property of polydiacetylene (PDA)-based hydrogel beads upon binding with BAs with an alginate solution that rendered a three-dimensional porous structure with a large surface area to fabricate this novel sensor.<\/p>\n<p>The researchers demonstrated that the developed sensor beads easily detect biogenic amines like cadaverine and propylamine both in solution and vapor forms via distinct changes in colour from blue to red. The team further put the sensor to test the spoilage of pork meat samples left at room temperature across 4 days. They showed that the sensor beads could efficiently track the gradual spoilage over time by showing a distinct shift in the shade of colour.<\/p>\n<p>The sensor is made of portable, light-weight beads and does not require complicated analytical equipment or skilled personnel. It offers rapid and seamless visual detection via colorimetric change in the beads from blue to red. As Prof. Seo observes: \u201cThe portable beads could be utilized on sites for monitoring whether the food quality is okay during storage and logistic chain. Further, the beads could be applied in evaluating whether ideal food storage and distribution conditions are well-preserved.\u201d<\/p>\n<p>Taken together, this portable PDA-based colorimetric sensor would facilitate the seamless monitoring of food spoilage during storage and distribution, and prevent health hazards arising from the ingestion of BAs.<\/p>\n<p><em><strong>Reference<\/strong><\/em><br \/>\n<em>1. doi: <a href=\"https:\/\/doi.org\/10.1016\/j.foodchem.2022.134317\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/doi.org\/10.1016\/j.foodchem.2022.134317<\/a><\/em><\/p>\n<\/div><\/section><br \/>\n<div  class='av-social-sharing-box  avia-builder-el-10  el_after_av_textblock  avia-builder-el-last  av-social-sharing-box-minimal '><div class='av-share-box'><h5 class='av-share-link-description av-no-toc '>Share this<\/h5><ul class='av-share-box-list noLightbox'><li class='av-share-link av-social-link-facebook' ><a target=\"_blank\" aria-label=\"Share on Facebook\" href='https:\/\/www.facebook.com\/sharer.php?u=https:\/\/fei-online.com\/biomaterials-scientists-develop-portable-colour-changing-food-spoilage-sensor\/&#038;t=Biomaterials%20scientists%20develop%20portable%20colour-changing%20food%20spoilage%20sensor' aria-hidden='false' data-av_icon='\ue8f3' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Facebook' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Facebook<\/span><\/a><\/li><li class='av-share-link av-social-link-twitter' ><a target=\"_blank\" aria-label=\"Share on Twitter\" href='https:\/\/twitter.com\/share?text=Biomaterials%20scientists%20develop%20portable%20colour-changing%20food%20spoilage%20sensor&#038;url=https:\/\/fei-online.com\/?p=11341' aria-hidden='false' data-av_icon='\ue8f1' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Twitter' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Twitter<\/span><\/a><\/li><li class='av-share-link av-social-link-whatsapp' ><a target=\"_blank\" aria-label=\"Share on WhatsApp\" href='https:\/\/api.whatsapp.com\/send?text=https:\/\/fei-online.com\/biomaterials-scientists-develop-portable-colour-changing-food-spoilage-sensor\/' aria-hidden='false' data-av_icon='\uf232' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on WhatsApp' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on WhatsApp<\/span><\/a><\/li><li class='av-share-link av-social-link-linkedin' ><a target=\"_blank\" aria-label=\"Share on LinkedIn\" href='https:\/\/linkedin.com\/shareArticle?mini=true&#038;title=Biomaterials%20scientists%20develop%20portable%20colour-changing%20food%20spoilage%20sensor&#038;url=https:\/\/fei-online.com\/biomaterials-scientists-develop-portable-colour-changing-food-spoilage-sensor\/' aria-hidden='false' data-av_icon='\ue8fc' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on LinkedIn' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on LinkedIn<\/span><\/a><\/li><li class='av-share-link av-social-link-mail' ><a  aria-label=\"Share by Mail\" href='mailto:?subject=Biomaterials%20scientists%20develop%20portable%20colour-changing%20food%20spoilage%20sensor&#038;body=https:\/\/fei-online.com\/biomaterials-scientists-develop-portable-colour-changing-food-spoilage-sensor\/' aria-hidden='false' data-av_icon='\ue805' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share by Mail'><span class='avia_hidden_link_text'>Share by Mail<\/span><\/a><\/li><\/ul><\/div><\/div><\/p><\/div><div class=\"flex_column av_one_fifth  flex_column_div av-zero-column-padding   avia-builder-el-11  el_after_av_three_fifth  avia-builder-el-last  \" style='border-radius:0px;
