Abstract

The invention discloses a method for extracting oat oil through microwave pretreatment. The method comprises the following steps: cleaning oat raw materials, draining the cleaned oat, and drying the oat in a drying oven; hulling the oat in a huller, and separating oat bran; crushing the oat bran in a crusher; and extracting the oat oil from the crushed oat bran, and performing microwave treatment after the oat is dried and before the dried oat is hulled in the huller, wherein the microwave treatment method comprises the following step of: putting the dried oat particles into a microwave dryer, wherein the power is regulated to be 180-900W, the treatment time is 60-150 seconds, the drying temperature in the drying step is 60 DEG C, and the moisture content of the dried oat is 15wt%. The method provided by the invention is simple and reliable, convenient to operate, low in cost, high in speed and high in leaching efficiency and has a high economic value.

Description

technical field [0001] The invention relates to a method for rapidly and efficiently extracting oat oil, in particular to a method for extracting oat oil by microwave pretreatment. Background technique [0002] Oats are annual herbaceous crops belonging to the Poaceae Avena genus. It is generally divided into two categories: lemma type (hull oat) and naked grain type (naked oat). my country's oat production areas are mainly concentrated in Inner Mongolia, Bashang in Hebei, Shanxi and other places, and mainly produce naked oats, which account for more than 90% of the total oat production, and all the grains are for food. The protein content in oats is about 15.6%, and the fat content is about 8.8%, both of which rank first in cereal crops. The carbohydrate content is about 64.8%. Se etc. are rich in content, which can enhance human immunity, delay aging, prevent cancer and fight cancer. Oatmeal is also rich in nutrients such as VB1, VB2, VE, niacin, and dietary fiber. In a...
