Generally, to cook oats using a regular cooker, you need to cook them for about 30 minutes. If you are using a pressure cooker to cook oats, you can usually cook them for about twenty minutes, but you need to soak them in water for about an hour before cooking them, so that the oatmeal rice will be soft and sticky.

The protein content of oats is very rich (15.6%), 1.6-2.3 times that of rice and wheat flour, ranking first in cereal grains. Oat protein has high nutritional value, containing 18 kinds of amino acids, of which 8 kinds are essential amino acids. 8 kinds of essential amino acids are not only rich in content but also in reasonable proportion, close to the nutritional pattern recommended by FAO/WHO, with high utilization rate in human body. The lysine content of oats is more than 2 times that of wheat and rice, and the tryptophan content is more than 1.7 times that of wheat and rice.
