What is freeze-drying?<\/h2>\n\n\n\n

Freeze-drying is a preservation processing technology that vacuum-dries food or materials in a frozen state, removing only the moisture by sublimation. Because it dries without applying heat,it can retain color, aroma, nutrients, and shape relatively intact<\/strong>which is its greatest feature.<\/p>\n\n\n\n

In the food industry, it is applied to instant miso soup and soups, fruit, vegetables, and even pharmaceuticals and space food, andit is recognized as a \"high-quality drying technology\"<\/strong>\u3002<\/p>\n\n\n\n

English notation: freeze-drying
Furigana: furiizu dorai<\/p>\n\n\n\n

Features and background of freeze-drying<\/h2>\n\n\n\n

Freeze-drying technology originally developed as a preservation application in the military and medical fields, and from the mid-20th century it came to be used in the food industry as well. Today,because it allows long-term storage while preserving a material's flavor and nutritional value at low temperature<\/strong>it has established itself as a high-value-added processing technology.<\/p>\n\n\n\n

Because the drying temperature is low,color and shape are less likely to break down, and it excels in \"good rehydration\" and \"texture reproducibility,\" so demand is expanding in instant foods and health foods. It is drawing attention especially in markets seeking additive-free products with a strong sense of the material itself<\/strong>\u3092\u6c42\u3081\u308b\u5e02\u5834\u3067\u6ce8\u76ee\u3055\u308c\u3066\u3044\u307e\u3059\u3002<\/p>\n\n\n\n

It is also widely used in fields that need \"food that is light, highly storable, and does not lose nutrients,\" such as disaster stockpiling, the outdoors, space food, and supplement uses.<\/p>\n\n\n\n

Examples of freeze-drying use at Agriture<\/h2>\n\n\n\n

At Agriture, in addition to ordinary hot-air drying, for some products and partner projects,freeze-drying-compatible OEM manufacturing<\/strong>is also possible. It is especially suited tocases where you want to make the most of a material's color and flavor<\/strong>as a powder ingredient, for ichimi, shichimi, and making original seasonings, seeand to products that can be eaten right after rehydration<\/strong>(e.g., instant soups, functional foods).<\/p>\n\n\n\n

Freeze-drying tends to raise unit cost as a processing technology, butit pairs well with product concepts that seek a sense of luxury and convenience<\/strong>and is proposed as a differentiating element.<\/p>\n\n\n\n

FAQ<\/h2>\n\n\n\n

Q. What is the difference between freeze-drying and dried vegetables?
A. Freeze-drying (freeze then vacuum-dry) tends to preserve nutrients and flavor, while dried vegetables are mainly hot-air dried, keeping costs down\u2014that is the difference.<\/p>\n\n\n\n

Q. Are freeze-dried foods additive-free?
A. Many products are additive-free and designed to make use of the material's own flavor, but depending on the product, seasonings and the like may be added.<\/p>\n\n\n\n

Q. Is it possible to make it at home?
A. It requires dedicated freeze-drying equipment and is difficult in an ordinary household, so it is common to use commercial products.<\/p>","protected":false},"featured_media":804,"template":"","meta":{"_acf_changed":false,"swell_btn_cv_data":"","ssp_meta_description":"\u30d5\u30ea\u30fc\u30ba\u30c9\u30e9\u30a4\u3068\u306f\u3001\u98df\u54c1\u3084\u7d20\u6750\u3092\u51cd\u7d50\u3055\u305b\u305f\u72b6\u614b\u3067\u771f\u7a7a\u4e7e\u71e5\u3057\u3001\u6c34\u5206\u3060\u3051\u3092\u6607\u83ef\u3055\u305b\u3066\u53d6\u308a\u9664\u304f\u4fdd\u5b58\u52a0\u5de5\u6280\u8853\u3067\u3059\u3002\u71b1\u3092\u52a0\u3048\u305a\u306b\u4e7e\u71e5\u3055\u305b\u308b\u305f\u3081\u3001 \u8272\u30fb\u9999\u308a\u30fb\u6804\u990a\u7d20\u30fb\u5f62\u72b6\u3092\u6bd4\u8f03\u7684\u305d\u306e\u307e\u307e\u6b8b\u3059\u3053\u3068\u304c\u3067\u304d\u308b \u306e\u304c\u6700\u5927\u306e\u7279\u5fb4\u3067\u3059\u3002","ssp_meta_keyword":"\u30d5\u30ea\u30fc\u30ba\u30c9\u30e9\u30a4"},"tags":[22],"class_list":["post-489","word","type-word","status-publish","has-post-thumbnail","hentry","tag-freeze-strawberry"],"acf":[],"_links":{"self":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/word\/489","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/word"}],"about":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/types\/word"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/media\/804"}],"wp:attachment":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/media?parent=489"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/tags?post=489"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
