Quercus acutissima, the Asian species of oak, is the source of the popular acorn fruit. It is native to Korea, China, and Japan, where it is widely used as a food source. In Korea, dotorimuk, made from the acorn, is very popular and is known as a healthy food. Acorn flour mixed with water is boiled hard for 5 minutes and the temperature is lowered down for 2-3 minutes to make an edible jelly. The taste of acorn is normally bitter but it becomes soft as it contains abundant tannins, and it is considered a good dietary food due to the low calorie count. As a beauty therapy, acorn flour, with its abundant tannins, is used traditionally as a face mask to minimize pore size and for skin firming. Acorn as a food is thought to get rid of heavy metals in body. It is used for the treatment of diarrhea, dysentery, burns, and oral inflammatory diseases. A study about acorn extracts showed their suppressive effect against obesity in differentiated 3T3-L1 cells obtained through anti-oxidation.
