The test results show that: when cooking rice with tap water, the degree of vitamin B.1 loss is proportional to the time and temperature of cooking rice, and the general loss is 30%; if using boiling water and distilled water to cook rice, it will not cause vitamin B.1 loss. The number of meters is directly proportional to the loss of vitamin B.1, but no matter whether boiled water, tap water or distilled water is used to wash the rice, the loss of vitamin B.1 is 40%. Can we get from this experimental result? ['Rice should be washed with boiling water and distilled water.', 'Save water when washing rice.', 'You should use boiling water to wash rice and cook rice.', 'The number of rice panning should be reduced, and boiling water should be used for cooking.']
