Brand new, unopened For preventing discoloration and oxidation of fresh fish, meat, vegetables, etc., and for maintaining quality. Isshin Tasuke is a high-quality ceramic fiber non-woven fabric blended with Photoelectron fiber, which improves the efficiency of heat conduction through far-infrared rays. It moderately absorbs drips from the surface of fish and meat, and at the same time promotes oxygen activity within the tissues while retaining an appropriate amount of moisture, dramatically preserving the freshness of food. Professional-Grade Features 1) Prevents discoloration of food. 2) Moderately absorbs drips from fish and meat, leaving the umami components of the food intact. 3) Promotes oxygen activity within the tissues of fish and meat while retaining an appropriate amount of moisture. 4) Can also be used to prevent vegetables and fruits from drying out by slightly moistening them. 5) Dramatically preserves the freshness of food. 6) Safe and hygienic as no adhesives or bleaching agents are used. Maintaining the Freshness of Vegetables: Lightly moisten and wrap. The far-infrared effect prevents moisture evaporation, keeping vegetables crisp for a long time. For preserving mitsuba (Japanese parsley) and green shiso, wrap them in Isshin Tasuke moistened with water and refrigerate. When storing cut salad, place Isshin Tasuke moistened with water on the top and bottom to keep it fresh for longer. For fish, meat, and vegetables, a high-performance freshness-preserving sheet chosen by professionals. Simply wrapping food with it provides excellent effects in preservation, moisture control, and deodorization, changing the common sense of food storage. Made of ceramic fiber non-woven fabric blended with Photoelectron fiber. It is hygienic and highly safe because no adhesives or bleaching agents are used in the manufacturing process. It can be washed and reused depending on the application, making it economical. Features of Ceramic Fiber Non-Woven Fabric: Ultra-fine particles of 0.3-micron ceramic are kneaded into the fibers (patented Photoelectron fiber) to create the non-woven fabric. The ultra-fine ceramic particles are completely kneaded into each fiber, so they do not dissolve even when wet. During freezing, it quickly passes through the maximum ice crystal formation temperature range (-1°C to -5°C), suppressing the destruction of cell membranes and reducing drip outflow after thawing. Various Uses: For storing and thawing fresh fish and meat, use it as is or wrap it after lightly moistening it. For preserving tuna, etc., and preventing discoloration after cutting, wrap Isshin Tasuke directly and then wrap with plastic wrap for storage. For white fish such as fugu (pufferfish), sea bream, and flounder, use it after moistening with water. L size (385mm x 240mm) Instant purchase welcome. Will be shipped in simple packaging.
