Smell: It smells stale, moldy, muddy, sour wine, metal and spicy. Indicates deterioration, or there is something wrong with the raw materials of olive fruit, or improper storage. Taste: it has taste, or it has no taste at all. Explain deterioration, refined oil or blended oil. In fact, Japan has always been a country that emphasizes "rice". Japanese people extract the essence from rice skin and germ and refine it into rice oil as edible oil, which is very nutritious. Rice oil production technology in Fengxian district is known as "rice gold" because it not only has a certain effect on "three highs", but also contributes to beauty and skin care and delays cell aging.
At present, the salad oil and blended oil sold in the market have all removed impurities. When a large amount of smoke comes out, the oil temperature has reached about 250 degrees Celsius, resulting in high-temperature deterioration of the oil. At this time, cooking will also lose vitamins and other nutrients in the raw materials of the dishes. Rice oil can be used repeatedly without deterioration and is suitable for frying. When the oil temperature of common edible oil exceeds the smoke point, the chemical structure of oil will change. The smoke point of rice oil is about 250 degrees Celsius, which is much higher than that of other common edible oils. Therefore, frying food with rice oil is healthier and more in line with the cooking style of China people.
