It is best to buy green leafy vegetables to the regular market. If the edible part of the vegetable is broken, it should be eaten immediately and not stored so that the broken part will not react after a long time of placement and produce toxic substances such as nitrite. If it is washed with detergent for vegetables and fruits, just use it according to the product instructions of the detergent. If it is cleaned with water, soak for 20 to 30 minutes before washing. In addition, wash vegetables with rice water, can effectively remove residual pesticides. 2, should not be stored at room temperature leftover vegetables. Summer, even if not overnight meals, must be refrigerated in time, not at room temperature, so as not to create conditions for the growth and reproduction of germs and the release of toxins. 3, restaurant dining less cold dishes. Hot days to restaurants, order as many hot dishes as possible, leftover vegetables should not be packaged. If you want to hold a wedding banquet, birthday banquets and other large banquets, to choose a hotel with sufficient reception capacity, because the need for a long time before the opening of some dishes finished or semi-finished products to make, if the food is not properly preserved, very easy to deteriorate. 4, eat less street shaved ice.
