Yet, preparing them is often a tearful affair due to an irritant chemical released when chopping. To address this nuisance, researchers have developed a new onion variety, the \u201csunion,\u201d which promises to solve the problem. This innovation could potentially revolutionize the way we cook, offering an alternative to traditional onions while preserving their nutritional benefits.<\/p>\n<div class=\"code-block code-block-4\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<h2>Onions vs. Sunions<\/h2>\n<p>Traditional onions, though tasty, carry a well-known reputation for making those who cut them cry. This reaction stems from the release of an enzyme called <strong>alliinase<\/strong> when an onion is cut. This enzyme interacts with sulfur-containing compounds, producing a gas, <i>propanthial-S-oxide<\/i>, that irritates our eyes. To avert tears, various tricks exist, such as freezing the onion or wearing protective eyewear.<\/p>\n<p>Sunions, an innovation developed by the German agrochemical company Bayer, offer a solution to this problem. Resulting from <strong>research work started in the 1980s<\/strong>, this variety was commercialized in the United States in 2018. The first Sunion fields were located in the states of Nevada and Washington, covering an area of 800 km\u00b2 with a yield of 22.5 tonnes per km\u00b2. Today, although their price is roughly three times that of ordinary onions, Sunions are beginning to gain a foothold in the French market.<\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<blockquote class=\"wp-embedded-content\" data-secret=\"4zNPljdVyL\">\n<p>A wood as transparent as glass: this durable invention is transforming construction materials and triggering an unprecedented wave of innovations<\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0A wood as transparent as glass: this durable invention bouleverse les mat\u00e9riaux de construction et d\u00e9clenche une vague d\u2019innovations sans pr\u00e9c\u00e9dent\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/07\/16\/ces-oignons-ne-feront-plus-pleurer-personne-decouvrez-la-percee-scientifique-qui-va-bouleverser-votre-cuisine-et-en-finir-avec-les-larmes\/about:blank\" data-secret=\"4zNPljdVyL\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" data-rocket-lazyload=\"fitvidscompatible\" data-lazy-src=\"https:\/\/vivredemain.fr\/2025\/04\/18\/un-bois-aussi-transparent-que-du-verre-cette-invention-durable-bouleverse-les-materiaux-de-construction-et-declenche-une-vague-dinnovations-sans-precedent\/embed\/#?secret=46thyNO2s1#?secret=4zNPljdVyL\"><\/iframe><noscript><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0Un bois aussi transparent que du verre : cette invention durable bouleverse les mat\u00e9riaux de construction et d\u00e9clenche une vague d\u2019innovations sans pr\u00e9c\u00e9dent\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/04\/18\/un-bois-aussi-transparent-que-du-verre-cette-invention-durable-bouleverse-les-materiaux-de-construction-et-declenche-une-vague-dinnovations-sans-precedent\/embed\/#?secret=46thyNO2s1#?secret=4zNPljdVyL\" data-secret=\"4zNPljdVyL\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/noscript><\/p>\n<h2>Tear-Free Guarantee<\/h2>\n<p>Sunions were developed through natural crossings without GMOs, aiming to reduce the production of propanthial-S-oxide. Another key aspect of the production process is the post-harvest maturation period, which further reduces the onions&#8217; irritating potential. This enables Sunions to be handled without triggering tears, as evidenced by 93% of consumers who report no tingling or tearing when using them.<\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<p>In addition to being tear-free, Sunions do not lose any of their nutritional virtues. They are <strong>rich in antioxidants and vitamins A, B, and E<\/strong>, contributing to strengthen the immune system, slow cellular aging, and improve blood circulation thanks to their anti-inflammatory and antibacterial properties. However, some consumers find that Sunions have a milder taste and aroma, a direct consequence of the absence of sulfoxides.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"3JykD5Q2Or\">\n<p>A fatal error in Turkmenistan: discover how a simple blunder opened the legendary Gate of Hell, a staggering phenomenon that defies human understanding<\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0Une erreur fatale au Turkm\u00e9nistan : d\u00e9couvrez comment une simple boulette a ouvert la l\u00e9gendaire Porte de l\u2019Enfer, un ph\u00e9nom\u00e8ne stup\u00e9fiant qui d\u00e9fie l\u2019entendement humain\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/07\/16\/ces-oignons-ne-feront-plus-pleurer-personne-decouvrez-la-percee-scientifique-qui-va-bouleverser-votre-cuisine-et-en-finir-avec-les-larmes\/about:blank\" data-secret=\"3JykD5Q2Or\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" data-rocket-lazyload=\"fitvidscompatible\" data-lazy-src=\"https:\/\/vivredemain.fr\/2025\/06\/30\/une-erreur-fatale-au-turkmenistan-decouvrez-comment-une-simple-boulette-a-ouvert-la-legendaire-porte-de-lenfer-un-phenomene-stupefiant-qui-defie-lentendement-humain\/embed\/#?secret=8IJ9loukuH#?secret=3JykD5Q2Or\"><\/iframe><noscript><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0Une erreur fatale au Turkm\u00e9nistan : d\u00e9couvrez comment une simple boulette a ouvert la l\u00e9gendaire Porte de l\u2019Enfer, un ph\u00e9nom\u00e8ne stup\u00e9fiant qui d\u00e9fie l\u2019entendement humain\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/06\/30\/une-erreur-fatale-au-turkmenistan-decouvrez-comment-une-simple-boulette-a-ouvert-la-legendaire-porte-de-lenfer-un-phenomene-stupefiant-qui-defie-lentendement-humain\/embed\/#?secret=8IJ9loukuH#?secret=3JykD5Q2Or\" data-secret=\"3JykD5Q2Or\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/noscript><\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<h2>Impact on Cooking and Health<\/h2>\n<p>The introduction of Sunions into cooking can transform culinary habits.
