What Are Agar (Agar Agar) And Kanten?
Agar (or sometimes called agar agar) and Kanten (寒天) are a white and semi-translucent gelatinous substance, obtained from algae. It is a great alternative to animal or chemical-based gelatin.
It was first discovered in 1658 by Minoya Tarozaemon (美濃屋 太郎左衛門) in Japan (source). The word “agar” comes from agar-agar, the Malay/Indonesian name for red algae.
Although the word “kanten” is used as a Japanese translation of “agar”, Japanese consider agar and kanten a separate ingredient because they come from different algae.
Agar is from Carrageenan, which is extracted from red edible seaweed (スギノリ・ツノマタ). Kanten is made of Gelidiales, red edible seaweed (テングサ・オゴノリ).
Agar is clear and has more soft smooth texture. It is used to make all types of jellies, puddings, and custards.
Kanten is semi-translucent and firmer with less jiggle. It is used to make wagashi (Japanese confectionery) like yokan and anmitsu.

Agar/Kanten has several advantages over the traditional gelatin.
- It’s a natural vegetable gelatin, which is approximately 80% fiber. It’s suitable for vegetarian and vegan diets.
- I has no taste, no odor, and semi-translucent.
- It sets more firmly than gelatin and is able to set at room temperature.
- Unlike gelatin, it can stay in jelly form at warmer temperature.
- Great for dieting as it makes you feel full.
Types Of Agar/Kanten And Where To Find It?
There are 4 types:
