. The weather is getting hotter and hotter. Many people regard the refrigerator at home as a universal treasure chest, and put all the leftover food and drink in the refrigerator. Nearly 6 adults often put the food in the refrigerator out of date, resulting in the refrigerator being dirtier than the toilet! Let’s take a look with you.
Does the refrigerator smell?
must be cleaned. Generally speaking, the peculiar smell emitted from the refrigerator is hydrogen sulfide, methylamine and other gases produced by bacterial metabolism.
some parts of China are located in subtropical, warm and humid environment, which is the hotbed of mold. If the food materials are not properly preserved, there may be mold pollution. The most common are aflatoxin and ochratoxin:
aflatoxin: Grade 1 carcinogen
aflatoxin is the first-class carcinogen recognized by the World Health Organization, It has hepatotoxicity. Long term exposure will cause chronic hepatitis and liver cirrhosis, and make hepatocytes mutate into cancer cells.
aflatoxin has the characteristics of high thermal stability, strong toxicity and stable toxicity. It can be destroyed only after heating above 280 ℃, which is not easy to remove.
it is generally believed that only moldy peanuts and their products contain aflatoxin. In fact, Cereals, north-south dry goods and spices can not escape the pollution of aflatoxin growth.
in order to avoid eating aflatoxin by mistake, it is recommended to choose foods with normal appearance, fresh and complete packaging. It is best to choose small packaging products that can be eaten at one time. If there is mildew, do not eat them again.
ochratoxin: Class 2 pathogenic factor
ochratoxin is a toxin produced by the massive growth of molds under the condition of improper storage of grains. It is toxic to the kidney, inhibits the normal immune ability of human body and is carcinogenic.
ochratoxin producing mold must have water and air to grow. It is recommended to choose completely dry and packaged products when purchasing grains.
pay attention to the preservation of food after opening. Do not store it too long. Avoid humidity in the storage environment and isolate the food from the moisture in the air as far as possible.
The use of refrigerator is particular.
eating overnight dishes does not cause cancer, but it may cause diarrhea.
the nitrite content in overnight dishes is very low, so there is no need to worry about cancer.
however, since the temperature of the refrigerator is only 4 degrees Celsius, it can only inhibit the growth of bacteria and can not play the function of sterilization.
if the temperature of the refrigerator is not low enough, resulting in microbial pollution of dishes, it is easy to cause acute gastroenteritis.
once a woman kept the cooked hairy crab in the refrigerator and ate it three days later. Unexpectedly, she died of sepsis caused by microbial infection.
correct practice: it is recommended to cook just the right amount of each meal according to the number of people eating at home. The leftovers can only be placed in the refrigerator for 1 day at most to avoid eating problems.
don’t put leftovers on plates
many housewives put leftovers from three meals directly on plates and put them in the refrigerator. Even if there is not enough space, they pile dishes layer by layer and squeeze them into the narrow space of the refrigerator.
in fact, the space for food in the refrigerator should not exceed 70%, otherwise it is easy to breed bacteria.
sometimes the unstable placement of plates will make the food soup spill out, provide an environment for bacteria breeding, and make the food taste stale, resulting in peculiar smell in the refrigerator.
correct practice: the remaining meals should be put into a covered fresh-keeping box and sealed before being put into the refrigerator.
do not put high-temperature food in the refrigerator
put it directly into the refrigerator while the food and soup are still high temperature, which will not only increase the temperature in the refrigerator in a short time, but also condense a large amount of water vapor. This humid environment will accelerate the speed of food deterioration.
correct practice: cool the remaining cooked food first and then put it into the refrigerator. Take out the dishes from the refrigerator. When heating the food, ensure that the temperature reaches more than 60 ℃ in order to eliminate microorganisms in the food.
5 tips for refrigerator management
filling date to prevent expiration
refrigerated or frozen food materials shall be managed by categories and labeled. The product name and storage date of the outer package can be cut off and put together in a sealed bag or pasted outside the fresh-keeping box, For identification.
often take food outside
if the food needs to be stored for a long time, try to put it inside. The more commonly used food can be easily taken in the front section.
raw and cooked food shall be separated
and placed according to the principle of “cooked and unborn”, so as to avoid blood and water dripping onto the food below and being polluted.
repackaged to keep fresh
food in excess shall be repackaged in sealed bags or fresh-keeping boxes.
regular cleaning every week
it is recommended to clean and wipe the refrigerator once a week.
Wonderful use of refrigerator
most people buy refrigerators home and generally only use them to refrigerate and preserve food. However, refrigerators actually have many wonderful uses. These new uses can bring more convenience to life.
1. Silk stockings prolong life
many girls often break their brains when they are born as silk stockings. Do not unpack the newly bought silk stockings and put them directly in the refrigerator freezer for 1 ~ 2 days. Then take it out for half a day or so and put it on. The change of temperature can increase the toughness of silk stockings, and the frozen silk stockings are less likely to be damaged.
2. Moisture can be recovered
if biscuits are damp, they don’t taste crispy, but they haven’t exceeded the shelf life. Unfortunately, they can be frozen in the refrigerator for about 24 hours. Take out the biscuits and the taste will return to its original crispness.
3. Flat silk clothes
silk clothes are wrinkled after washing. Clothes with too soft texture are very troublesome to iron. You can put the clothes in a plastic bag in the refrigerator for a few minutes, take them out and iron them again.
4. Cut the egg yolk without breaking
the freshly cooked boiled egg or tea egg is broken with a knife. All the egg yolks can be put into the refrigerator for refrigeration for 1 hour. When the egg yolk is slightly cold and solid, cut it again. The incision of the egg is flat and the egg yolk will not break.
5. Beans quickly boil
red beans. If it is difficult to boil them thoroughly without soaking, you can boil them together with water and put them into the refrigerator freezer for about 2 hours after cooling. After taking them out, there will be some icing on the water surface. At this time, heat the pot again. The heating degree of water and red beans is different. The temperature changes so that the red beans will cook rotten after about 20 minutes.
6. Candles are resistant to burning and do not drip wax
four hours before using candles, put the candles in the refrigerator to freeze. After the cold candles are ignited, they will burn slowly and for a long time, and it is not easy to drip wax.
7. Remove the chewing gum
when the chewing gum accidentally sticks to the article, you can put it together with the stuck article in the refrigerator and freeze it. After about 1 hour, the chewing gum will become brittle and hard. At this time, take out the article and peel the chewing gum gently with your fingernail.
