It also provides methodology for accurate and high-throughput colour quantifi-cation. This information builds a strong basis for additional work to investigate commercial scale-up and colour performance in food applications,\u201d says lead author Jay Howard.<\/p>\n<p>The researchers selected four dozen amaranth varieties from the USDA National Plant Germplasm System, representing a full spectrum of foliage coloration from deep burgundy to lime green. They grew the plants in a greenhouse and extracted pigments from stem and leaf tissue using a simple water method, in accordance with FDA guidelines. Then they fed the extracts through lab equipment to discover which betalain pigments were most prevalent.<\/p>\n<p>\u201cWe developed a chemical profile for each extract, looking at the ratio of dominant pigments. Some of the minor components, which are co-extracted in the water method, may contribute to the colour and stability of the main pigments. These properties are very interesting for food companies, because you might get a very bright pink or red colour, but then if it fades to brown after a day, it\u2019s useless. We found that, for some of our plants, the extracts were stable over days or even weeks. We\u2019re planning to follow up with more research on that,\u201d says study co-author Chance Riggins, research assistant professor in the Department of Crop Sciences the College of Agricultural, Consumer and Environmental Sciences (ACES) at the University of Illinois Urbana-Champaign.<\/p>\n<p>Most food companies currently source betalains as a co-product from red beet production, but Riggins says beet-derived pigments have some drawbacks. \u201cBeets are off-putting for some people. Those earthy flavour compounds often get transferred in a basic betalain extract.<br \/>\nSo, food companies are really open to natural food colorants from alternative sources and doing it in a way that could extend applications for different food products,\u201d he says.<\/p>\n<p>The researchers did a basic taste and colour test by mixing up a Kool-Aid-type concoction with their amaranth extracts. \u201cA few were slightly reminiscent of beets, but mostly we couldn\u2019t smell or taste anything,\u201d Riggins says. For a few amaranth varieties in the study, the betalain extracts appeared bluer than the bright reds from beets. With further research, the unique colour could fill a gap in the available portfolio of natural colorants.<\/p>\n<p>Another plus? Amaranths are famously tough and can grow in less-than-pristine conditions. Betalains, along with anthocyanins and other pigments, allow amaranths to handle environmental stress, acting as antioxidants and repairing cellular damage due to drought, heat, or intense solar exposure. But the researchers don\u2019t expect amaranth plantations to start popping up on weedy roadsides across the U.S., at least not solely for betalain production. \u201cI don\u2019t think amaranth is ever going to be a crop strictly grown for pigmentation; there aren\u2019t many crops like that. But amaranth is already approved by the FDA for food use, and under those guidelines could be approved as a natural food colorant,\u201d Riggins says. \u201cAmaranth is mainly grown commercially for the seeds, often for gluten-free applications, but there\u2019s a lot of biomass wasted from the seed harvest. Our data suggests the pigment could be a value-added product down the line.\u201d<\/p>\n<p>Howard adds: \u201cThe shift from synthetic ingredients requires a diverse toolkit of natural options so that the food industry can match the colour hue and stability of synthetic colours at an effective cost-in-use. Amaranth is an exciting crop that addresses each of these points \u2013 it is a scalable, resilient, antioxidant-rich crop with impressive biomass yields. Unlike red beets, the current sole commercial source of betalains, vegetable amaranth also provides green chlorophylls and yellow carotenoids that provide additional hues. These added byproducts enable lower costs and greater sustainability.\u201d<\/p>\n<p>The study extends a longstanding research theme in the College of ACES that investigates natural food compounds as colorants and health promoters. For example, as an undergraduate, Howard got involved in the purple corn project [3] to identify rich sources of anthocyanin pigments in purple and blue corn varieties.<\/p>\n<\/div><\/section><br \/>\n<section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock  '   itemprop=\"text\" ><p><em><strong>References<\/strong><\/em><\/p>\n<p><em>1. <a href=\"https:\/\/www.fda.gov\/food\/food-additives-petitions\/color-additives-questions-and-answers-consumers\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.fda.gov\/food\/food-additives-petitions\/color-additives-questions-and-answers-consumers<\/a><\/em><br \/>\n<em> 2. <a href=\"https:\/\/doi.org\/10.3389\/fpls.2022.932440\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/doi.org\/10.3389\/fpls.2022.932440<\/a><\/em><br \/>\n<em> 3. <a href=\"https:\/\/aces.illinois.edu\/news\/blue-and-purple-corn-not-just-tortilla-chips-anymore\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/aces.illinois.edu\/news\/blue-and-purple-corn-not-just-tortilla-chips-anymore<\/a><\/em><\/p>\n<\/div><\/section><br \/>\n<div  class='av-social-sharing-box  avia-builder-el-12  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\/amaranth-works-as-a-natural-food-dye\/&#038;t=Amaranth%20works%20as%20a%20natural%20food%20dye' 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=Amaranth%20works%20as%20a%20natural%20food%20dye&#038;url=https:\/\/fei-online.com\/?p=11209' 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\/amaranth-works-as-a-natural-food-dye\/' 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=Amaranth%20works%20as%20a%20natural%20food%20dye&#038;url=https:\/\/fei-online.com\/amaranth-works-as-a-natural-food-dye\/' 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=Amaranth%20works%20as%20a%20natural%20food%20dye&#038;body=https:\/\/fei-online.com\/amaranth-works-as-a-natural-food-dye\/' 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-13  el_after_av_three_fifth  avia-builder-el-last  \" style='border-radius:0px;
