- n. Wheat gluten.
According to the Oxford English Dictionary, the term was coined in Japanese by philosopher George Ohsawa in the early 1960s to refer to wheat gluten as used in Ohsawa's macrobiotic system of cooking and health. It may derive from 成 (sei-, "be, become") or 製 (-sei, "made of") + 蛋 (tan-) (from 蛋白 ("protein")). In Japan, wheat gluten itself is usually referred to as 麩 (fu, "wheat bran, gluten"). (Wiktionary)
