Unrevailed Sushi Freshness, Every Time with TREHA™

Rice is a staple of global cuisine, with consumption reaching over 500 million metric tons in 2020/2021 alone. However, keeping rice fresh after cooking is a challenge—cold, leftover rice often becomes hard and unappetizing, contributing to unnecessary food waste.

At Nagase Viita, we’re committed to food innovation. Our solution, TREHA™, is designed to preserve the quality of cooked rice, helping you deliver the perfect dish every time while reducing waste.

Let us help you elevate your sushi rice with TREHA™—because quality shouldn’t be compromised.

  • Create the Ultimate Sushi Experience with TREHA™

    Consumers crave fresh, authentic, and flavorful sushi that they can truly savor. However, a common challenge many chefs face is preserving the quality of all sushi components – raw seafood and vinegared rice – at their peak. While low temperatures are essential for maintaining seafood freshness, they can negatively impact the texture of rice. With TREHA™, we’ve solved this issue, allowing sushi rice to stay fresh and retain its quality even in cold storage.

  • TREHA™, a Culinary Secret from Japan.

    TREHA™ is the leading brand of trehalose, a versatile food ingredient known for its remarkable natural ability to extend freshness in various foods. One key benefit is its superior moisture retention, which helps maintain the moisture and softness of sushi rice.

    It even allows sushi rice to be frozen without losing quality! By adjusting the formulation for low temperatures, the rice retains its moisture and softness after freezing, as shown in the image below. Because nobody likes hardened rice, right?
