Acorn, alternative name: the academy name is chestnut cocoon, Quercus mongolica, and the name is oak seed, oak tree, and Mongolian oak. Most of the plants refer to nuts of the genus Quercus, which are similar to silkworm cocoons in the areas of Wan, Dabie mountain and eastern mountain, and are also called chestnut cocoons. The acorn has hard shell, brownish red color, and inner core such as peanut kernel, and is rich in starch. The content of starch and protein in the acorn is slightly lower than that of the rice, and 600 kcal of heat and 8 g of protein can be provided for every 100 g of acorn; the amino acids contained in acorn seeds are similar to milk, beans and meat; the acorn seed also contains carotene, vitamins B1, B2 and malic acid. The acorn seeds are rich in grease, and the extracted oil is similar to olive oil, so that the acorn seeds are good edible oil. In view of the nutritional value of oak seed, foreign botanicals also optimistically predict that oak will become a "food crop" in the future. The acorn seed is rich in protein, fat, tannin, potassium, sodium, calcium, magnesium and other trace elements necessary for human body.
However, in the existing processing method of acorn seeds, the acorn seed starch is sold only by simple grinding and precipitation, the extraction rate of the starch is low, and the shelf life is short.
