KONJAC

Features

Made from a type of potatoes, konjac is a popular processed food in Japan.

Free of gluten and low in calories, konjac goes well with a variety of ingredients and adds an accent to dishes due to its distinct, chewy texture.

In particular, shirataki, a type of noodle-shaped konjac, can be used to make healthy dishes as it can be used as a substitute for spaghetti.

Production of Konjac Potatoes

Konjac plants have been grown in Gunma Prefecture since the 1500s and now the crop accounts for over 90% of Japan’s share.

Konjac plants are delicate; they prefer well-draining soil, mild summers and dry winters. Gunma offers the perfect climate for growing konjac potatoes.

It takes 3 to 4 years until the plants are ready for harvest and high level of farming techniques is required. Japan’s one and only konjac research center is located in Gunma Prefecture and high-quality potatoes are produced thanks to the new varieties and agricultural methods that are developed there.

Making Konjac Products

Konjac products are made up of 98% clean and tasty water from Gunma, and a dietary fiber called glucomannan. Glucomannan expands when mixed with water and coagulates when calcium is added, creating a distinct texture unique to konjac.

During the coagulation process, konjac can be colored and shaped into various forms, including squares, balls or thin strings, leading to the development of a variety of products.
