Typical high-temperature drying dries it in a short time at around 70 degrees, but with this method heat-sensitive components and aroma compounds are easily lost, and the strong airflow also blows the aroma away.<\/p>\n<p>Yomogi's aroma compounds include cineole, beta-caryophyllene, and alpha-thujone, which are the source of its distinctive young-grass scent. To protect these precious components, technology that dries slowly at low temperature is essential.<\/p>\n<div data-type=\"table_of_contents\">\n<h3 class=\"wp-block-heading\">Recommended reading<\/h3>\n<ul>\n<li><a href=\"https:\/\/agriture.jp\/en\/sustainable\/agriture\/\">Agriture's sustainable initiatives<\/a><\/li>\n<li><a href=\"https:\/\/agriture.jp\/en\/wholesale-oem\/\">wholesale and OEM of commercial dried vegetables<\/a><\/li>\n<\/ul>\n<\/div>\n<figure class=\"wp-block-image\"><a href=\"https:\/\/agriture.jp\/en\/novelty\/\" target=\"_self\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/storage.googleapis.com\/studio-cms-assets\/projects\/9YWyw1reqM\/s-1280x720_v-fms_webp_2ed11573-ad31-4ace-a9ba-3de9d75f92b5.jpg\" alt=\"\u30b5\u30b9\u30c6\u30a3\u30ca\u30d6\u30eb\u306a\u8ca9\u4fc3\u7269\u3092\u5236\u4f5c\" width=\"\" height=\"\"><\/a><\/figure>\n<h2 class=\"wp-block-heading\" id=\"index_oLqgL_fZ\"><strong>The traits of yomogi that change by region, and how to choose<\/strong><\/h2>\n<p>Even saying domestic yomogi, the quality and traits differ greatly by growing region.<\/p>\n<h3 class=\"wp-block-heading\" id=\"index_qy4Hkt0E\"><strong>Understanding the traits of the major growing regions<\/strong><\/h3>\n<p>Yomogi is grown across Japan, but especially noteworthy are the Yamato Kogen area and the Okuetsu area. In Nara's Yamato Kogen, yomogi cultivation got underway in earnest from Reiwa 3, and it's also anticipated as a measure against abandoned farmland. Thanks to the rich natural environment and moderate climate conditions, this region can grow aromatic, good-quality leaves. Pesticide-free cultivation is also done in Yamaguchi, Tokushima, and elsewhere, each with its own quality traits according to the soil and climate.<\/p>\n<h3 class=\"wp-block-heading\" id=\"index_9BEYA7jo\"><strong>The difference between organic and conventional cultivation<\/strong><\/h3>\n<p>Yomogi's cultivation method directly affects quality, an important element. In organic cultivation, no agrochemicals or chemical fertilizers are used, and it's grown by making the most of nature's power. A big appeal of pesticide-free yomogi is that there's no risk of chemical residue, so it can be used with peace of mind. On the other hand, organic cultivation takes effort, and the yield tends to be less stable, which is a challenge. Conventional cultivation allows efficient production, but managing agrochemical residue becomes important.<\/p>\n<h2 class=\"wp-block-heading\" id=\"index_s6YiluWn\"><strong>Why harvest timing determines quality<\/strong><\/h2>\n<p>Yomogi's aroma and quality change greatly with harvest timing. The new shoots picked in spring are the most aromatic and are characterized by a soft texture. Yomogi at this time is rich in chlorophyll and shows a vivid green. The whole young leaf is covered in fine hairs and looks whitish-green, and these hairs play the role of a binder that produces the chewy texture of yomogi mochi.<\/p>\n<p>As growth advances, yomogi reaches a height of about 50 to 100cm, and the texture of the leaves and the balance of components change too. Choosing the optimal harvest timing according to use is the key to obtaining high-quality yomogi raw material. Young spring leaves for Japanese sweets, matured leaves for health foods -- discerning the harvest timing to suit the purpose is called for.<\/p>\n<figure class=\"wp-block-image\"><a href=\"https:\/\/agriture.jp\/en\/novelty\/\" target=\"_self\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/storage.googleapis.com\/studio-cms-assets\/projects\/9YWyw1reqM\/s-1280x720_v-fms_webp_2ed11573-ad31-4ace-a9ba-3de9d75f92b5.jpg\" alt=\"\u30b5\u30b9\u30c6\u30a3\u30ca\u30d6\u30eb\u306a\u8ca9\u4fc3\u7269\u3092\u5236\u4f5c\" width=\"\" height=\"\"><\/a><\/figure>\n<h2 class=\"wp-block-heading\" id=\"index_CQf7ifTy\"><strong>Processing technology governs quality<\/strong><\/h2>\n<h3 class=\"wp-block-heading\" id=\"index_OS082Qrk\"><strong>Particle-size adjustment in powdering<\/strong><\/h3>\n<p>The quality of yomogi powder changes greatly with particle size. A coarser powder suits uses where you want to keep texture and aroma strong, ideal for Japanese sweets such as yomogi mochi and kusa-dango. A finer powder, on the other hand, suits drinks and health foods that need coloring and even blending. Particle-size adjustment to suit the use is a point to nail that governs the product's quality.<\/p>\n<h3 class=\"wp-block-heading\" id=\"index_MsaO__nL\"><strong>Color and aroma retention technology<\/strong><\/h3>\n<p>High-quality yomogi powder retains a vivid green and rich aroma. To achieve this, low-temperature drying and appropriate processing steps are essential. Through a concentration technology that makes 100g of powder from 1000g or more of yomogi, products are made that provide ample flavor and nutrition even in small amounts. When appropriate supplement-grade processing is done, the color and aroma may settle somewhat, but this is also proof that quality control is thorough.<\/p>\n<h2 class=\"wp-block-heading\" id=\"index_F8LsJ04_\"><strong>Practical check points for discerning quality standards<\/strong><\/h2>\n<p>To choose high-quality domestic yomogi, there are several concrete check points. First, check the color. Ones keeping a vivid green are proof that appropriate drying and storage were done. Ones discolored brown may have deteriorated from high-temperature drying or long-term storage.<\/p>\n<p>Next is the aroma. What's called for is whether you can sense yomogi's characteristic fresh, deep aroma. If the aroma is weak or only a grassy smell stands out, there's a chance the aroma compounds were lost in the drying process. Clear labeling of growing region and cultivation method is also an indicator of reliability. Choosing ones with pesticide-free cultivation or organic certification and specific growing-region information listed is wise.<\/p>\n<p>For powder, uniformity of particle size is a check point too. Check whether it's processed to an appropriate particle size for the use and isn't clumping. Storage method is also important, and checking whether it's stored appropriately away from direct sunlight and heat\/humidity lets you judge the state of quality maintenance.<\/p>\n<h2 class=\"wp-block-heading\" id=\"index_tfbNMYaN\"><strong>Summary: choosing domestic yomogi with quality in mind<\/strong><\/h2>\n<p>The quality of domestic yomogi is affected in combination by four elements: growing region, cultivation method, harvest timing, and processing technology. Drying technology in particular is the most important point that determines quality, and drying slowly at low temperature lets you retain nutrition and aroma to the maximum.<\/p>\n<p>Rather than just the labels \"domestic\" and \"pesticide-free,\" checking down to specific growing-region information and processing method is the key to choosing truly high-quality yomogi. Understand concrete quality indicators such as color, aroma, and particle size, and choose the product optimal for your use. High-quality domestic yomogi shows its true worth across a wide range of uses, from Japanese sweets to health foods.<\/p>\n<figure class=\"wp-block-image\" data-thread=\"\"><a href=\"https:\/\/agriture.jp\/en\/novelty\/\" target=\"_self\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/storage.googleapis.com\/studio-cms-assets\/projects\/9YWyw1reqM\/s-1280x720_v-fms_webp_2ed11573-ad31-4ace-a9ba-3de9d75f92b5.jpg\" alt=\"\u30b5\u30b9\u30c6\u30a3\u30ca\u30d6\u30eb\u306a\u8ca9\u4fc3\u7269\u3092\u5236\u4f5c\" width=\"\" height=\"\"><\/a><\/figure>","protected":false},"excerpt":{"rendered":"<p>\u30e8\u30e2\u30ae\u306e\u54c1\u8cea\u3092\u8a9e\u308b\u4e0a\u3067\u3001\u6700\u3082\u91cd\u8981\u306a\u8981\u7d20\u306f\u4f55\u3060\u3068\u601d\u3044\u307e\u3059\u304b? \u591a\u304f\u306e\u4eba\u304c\u300c\u56fd\u7523\u300d\u300c\u7121\u8fb2\u85ac\u300d\u3068\u3044\u3046\u8a00\u8449\u306b\u6ce8\u76ee\u3057\u307e\u3059 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":769,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"swell_btn_cv_data":"","footnotes":"","ssp_meta_description":"\u30e8\u30e2\u30ae\u306e\u54c1\u8cea\u3092\u8a9e\u308b\u4e0a\u3067\u3001\u6700\u3082\u91cd\u8981\u306a\u8981\u7d20\u306f\u4f55\u3060\u3068\u601d\u3044\u307e\u3059\u304b? \u591a\u304f\u306e\u4eba\u304c\u300c\u56fd\u7523\u300d\u300c\u7121\u8fb2\u85ac\u300d\u3068\u3044\u3046\u8a00\u8449\u306b\u6ce8\u76ee\u3057\u307e\u3059\u304c\u3001\u5b9f\u306f\u54c1\u8cea\u3092\u6c7a\u5b9a\u3065\u3051\u308b\u6700\u5927\u306e\u8981\u56e0\u306f\u300c\u4e7e\u71e5\u6280\u8853\u300d\u3067\u3059\u3002","ssp_meta_keyword":"\u56fd\u7523\u30e8\u30e2\u30ae\u306e\u54c1\u8cea\u57fa\u6e96\u3068\u306f,\u7523\u5730,\u683d\u57f9,\u52a0\u5de5\u3067\u898b\u6975\u3081\u308b\u30dd\u30a4\u30f3\u30c8","ssp_meta_canonical":"","ssp_meta_robots":"","ssp_meta_title":""},"categories":[39,50],"tags":[23,62],"vegetable":[],"class_list":["post-450","sustainable","type-sustainable","status-publish","format-standard","has-post-thumbnail","hentry","category-sustainability","category-yomogi","tag-yomogi","tag-domestic"],"acf":{"summary":"\u56fd\u7523\u30e8\u30e2\u30ae\u306e\u54c1\u8cea\u57fa\u6e96\u306f\u7523\u5730\u30fb\u683d\u57f9\u65b9\u6cd5\u30fb\u53ce\u7a6b\u6642\u671f\u30fb\u52a0\u5de5\u6280\u8853\u306e4\u8981\u7d20\u3067\u6c7a\u307e\u308a\u3001\u7279\u306b\u91cd\u8981\u306a\u306e\u306f\u4f4e\u6e29\u4e7e\u71e5\u6280\u8853\u3067\u3059\u3002\u4e00\u822c\u7684\u306a70\u2103\u306e\u9ad8\u6e29\u4e7e\u71e5\u3067\u306f\u30b7\u30cd\u30aa\u30fc\u30eb\u3084\u03b2-\u30ab\u30ea\u30aa\u30d5\u30a3\u30ec\u30f3\u306a\u3069\u9999\u308a\u6210\u5206\u304c\u5931\u308f\u308c\u307e\u3059\u3002\u5927\u548c\u9ad8\u539f\u3084\u5965\u8d8a\u306a\u3069\u4e3b\u8981\u7523\u5730\u306e\u7279\u6027\u3001\u6709\u6a5f\u683d\u57f9\u3068\u6163\u884c\u683d\u57f9\u306e\u9055\u3044\u3001\u7c89\u672b\u306e\u7c92\u5ea6\u8abf\u6574\u3001\u8272\u30fb\u9999\u308a\u30fb\u5747\u4e00\u6027\u306e\u5177\u4f53\u7684\u306a\u30c1\u30a7\u30c3\u30af\u30dd\u30a4\u30f3\u30c8\u3092\u89e3\u8aac\u3057\u307e\u3059\u3002","product":1076},"_links":{"self":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable\/450","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable"}],"about":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/types\/sustainable"}],"author":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/comments?post=450"}],"version-history":[{"count":1,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable\/450\/revisions"}],"predecessor-version":[{"id":4757,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable\/450\/revisions\/4757"}],"acf:post":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/product\/1076"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/media\/769"}],"wp:attachment":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/media?parent=450"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/categories?post=450"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/tags?post=450"},{"taxonomy":"vegetable","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/vegetable?post=450"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
