Pickle the food to take care the salt candy exceeds standard Four unique skills can defend inferior nitrate
In autumn and winter, a lot of families begin to pickle food such as the mustard greens, pakchoi, garlic in syrup again. The expert reminds, there is mainly pickling the vegetables of safe problem in the food to pickle, especially it pickles vegetables to be what is called a short time " The cruel salted vegetables " .
Over one of time of salted vegetables are safer in month
Food institute's nutrition and food security of China Agricultural University are that associate professor Fan ZhiHong is pointed out, inferior nitrate comes from nitrate of higher content in the vegetables, nitrogen that the vegetables absorb in the nitrogen or soil is plain, accumulate nonpoisonous nitrate. Nitrate is changed into poisonous inferior nitrate some bacteria in the course of pickling, thus has brought the trouble. Later, inferior nitrate had utilized or decomposed by the bacterium gradually, the density will also drop gradually after reaching a peak, and even basically disappear.
Generally speaking, the intersection of salted vegetables and the intersection of Central Asia and nitrate begin, pickle later two or three days between more than ten days when being at most: When the high and salt of temperature is low in density, " inferior nitre peak " It is earlier to appear; The temperature is low and when salt quantity is great, " inferior nitre peak " on the contrary Appear later. Time when the northern area of our country salts the salted vegetables, pickled vegetable down usually takes in above one month, the southern area takes more than 20 days salting the pickled vegetable, pickles down too. Generally speaking, has already obviously dropped to the content of inferior nitrate after 20 days, it is very safe after one month. It was that kind of dish that only salted between two or three days and more than ten days down that really threatened the security of food, it is resting assured to be eaten to pickle the vegetables for over one month of time.
Expert remind still, might as well add some spring onions, ginger, garlic, Tabasco, lemon juice at the salted vegetables, these materials can all reduce the content of inferior nitrate, if vitamin C and other reducing materials in organic sulphide, lemon juice in the juice of the garlic can block inferior nitrate and formate inferior nitre amine carcinogen.
Chronic patient and children unsuitable to eat more salted vegetables
A lot of people like eating the sauced salted vegetables, Fan ZhiHong says, contain minerals such as meal fiber and a certain amount of calcium, magnesium, potassium,etc. in the sauced salted vegetables, lactic acid is fermented and acetic acid can produce small quantity B clan vitamin to ferment, so it is all right to eat a little salted vegetables on a small quantity as the appetizer.
However, it is improper if regard salted vegetables as the main dish and even substitute the fresh vegetables. Especially chronic patient and children, need to eat the fresh vegetables more to prevent disease or promote growth, and form the good meal habit with light taste, so is unsuitable to eat more sauced salted vegetables.
Pickle the food to take care the salt candy exceeds standard
The expert still shows, the salt or candy is that people pickle the main raw materials of the food. The salted vegetables of candy will not produce the noxious substance, but if you want to keep for a long time, the content of the candy should be more than 65%, in this way, will bring the trouble of high candy, high heat. The salted vegetables of salt should want to keep for a long time, the salt content should be up to about 15% too, the taste is too heavy and apt to make blood pressure rise too. Though most pickles products adopt the salt of candy and share the method and reduce salty degree at present.
But no matter how after all more high-quality salt, food of candy sauced salted vegetables is, compared with fresh products, the nutrition of pickling the vegetables fruit has greater losses, from the viewpoint of nutrition health, eat the fresh fruit of fresh dish a little better directly.
