I think the main reason is that the cost performance of Doric cooking oil is relatively high, which is really delicious but not expensive. The price of Doric sunflower seed oil, which I often eat, is less than 100 yuan. The color of the oil is clear and there is no impurity, and there is less cooking fume. The nitrogen-filled preservation technology ensures the freshness and nutrition of the oil, which is really the oil that my family likes.
