2, how to save overnight meals
1, different leftovers, must be stored separately, can avoid bacterial cross-contamination. You also need to use clean containers for airtight storage, such as plastic boxes, plastic bags, or attach a layer of plastic wrap to the dishes.
2, placed in the refrigerator under the most inside: If the dishes have been placed outside for two or three hours, we have used chopsticks and enthusiastically turned over, the shelf life will be shortened. This time to pay attention to, spread it a little flat, put it in the bottom of the refrigerator in the most inside, let it cool to the freezer temperature as soon as possible. It's OK to put it in the second meal, but be sure to heat it thoroughly to 100°C and keep it boiling for more than 3 minutes.
3, leftovers do not repeat multiple heating: the rest of the meat second meal is not finished, it is best to heat only half, the remaining part is still put back into the depths of the refrigerator. Leftovers should not be stored for too long, it is best to eat within 5-6 hours.
4, leftovers new, you can transform the leftovers into soup, such as leftover pork ribs with vegetables and noodles, made of vegetables and pork ribs soup noodles; leftover tomato scrambled eggs with fungus and noodles, transformed into a tomato-flavored pimple soup. In the past, people know that fried vegetables in the soup dissolved in vitamin C, should drink the vegetable soup. But nowadays, people pay more attention to food safety. If the ingredients of the dish is not fresh enough, the dish soup among the nitrite content is high, especially the leftover vegetable soup, it is best not to drink.
3, overnight meals why poisoning
From the point of view of food science, overnight is not the problem. Vegetables in the process of heating production, which itself contains reductase inactivation, can not be converted into nitrites in the dish, but the vegetables are not eaten, in the process of storage, will lead to the entry of bacteria, bacteria in the appropriate conditions of growth, nitrates may be converted into nitrites.
The process of converting nitrates into nitrites has nothing to do with whether or not they are overnight, but to meet the following points at the same time:
First of all: it depends on the content of the nitrites in the vegetables themselves. Different kinds of vegetables in the same storage conditions, the amount of nitrite generation is not consistent, usually the highest stem and leafy vegetables, melon vegetables a little lower, rhizomes and cauliflower class in the middle, therefore, if at the same time to buy different kinds of vegetables, you should eat the first stem and leafy, such as spinach and so on. If you are ready to make more dishes to eat hot the next day, you should try to do less stem and leafy vegetables and choose melon vegetables.
The second is "overnight vegetables" in what conditions to save. If the vegetables in the refrigerator cold (2 ℃ ~ 6 ℃), the increase of nitrite is less.
The third is the "overnight vegetables" preservation time, the harmful bacteria in the air will be attached to the leftover vegetables in two hours to begin to reproduce, so that the nitrite content will still increase.
4, can not eat the overnight food
1, leafy greens overnight the most dangerous. Usually stem and leafy vegetables with the highest nitrate content, melon vegetables slightly lower, root and cauliflower class in the middle. Therefore, if you buy a large number of vegetables at the same time, you should eat leafy vegetables first, such as cabbage, spinach and so on. If you are ready to make more dishes to eat hot the next day, you should try to do less stem and leafy vegetables, and choose melon vegetables.
2, overnight seafood damage liver and kidney. Crabs, fish, shrimp and other seafood, overnight will produce protein degradation, damage to liver and kidney function. If you really buy more, you can use the raw seafood in a plastic bag or plastic box, put into the refrigerator to freeze, next time to cook.
3, half-cooked eggs are easy to cause disease. Many people love to eat soft yolk half-cooked eggs, but this egg sterilization is not complete, coupled with the egg nutrient-rich, extraordinarily easy to breed bacteria, consumption will be dangerous. If the egg has been cooked, and low-temperature sealing properly preserved, overnight and then eat is no problem.
4, psyllium mushrooms to beware. Whether it is wild or artificial cultivation of psyllium, mushrooms, etc., are prone to residual nitrates. If you put the time is really a little long, you can only bear to throw away.
5, soup do not put metal utensils. Simmering soup is time-consuming and laborious, people tend to simmer a pot, eat for several days in a row. Leftover soup if long time in aluminum pot, iron pot, will precipitate harmful substances. The best way to save the soup is not to put salt and other seasonings in the soup, cooked soup with a clean spoon to drink the day, drink not finished, it is best to use the wok or preservation box stored in the refrigerator.
