Pinch the nose to your child to raise your nose. Can't the oranges and milk be eaten together? White shell eggs are more nutritious than red shell eggs? Can you rinse the cans easily with rice? Are these real?

 

 

 

This is true.

You can use rice.

 

 

 

Can you clean the cans easily?

 

 

 

After bottled food is finished, many people will use these bottles for the two time, for other things. But cleaning this kind of bottle is a headache. Some netizens say that it is easy to clean cans with rice. Is it true or false?

 

 

 

Experimental verification:

 

 

 

Rice has detergency and friction to clean cans.

 

 

 

Salad dressing bottles are common, and because cleaning is difficult, the odds of empty bottles being thrown away are very high. Next, try using the method of netizens to test whether rice can clean the salad sauce bottle.

 

 

 

Props: canned bottles, rice. First, open the cap and pour about more than 20 grains of rice into the bottle. Then, pour water, probably about 1/5 of the capacity of the bottle. Next, cover the cap and shake it vigorously for 10 seconds. Finally, open the lid and pour the muddy water out. After three times of shaking and washing, the salad dressing bottle was cleanly cleaned and the effect was very good.

 

 

 

There is also a bottle that is hard to wash, that is, with oil. For example, the kind of canned pepper oil. There is not much residue on the wall, but the oil is really troublesome. So can it be cleaned with rice? According to the earlier steps, put rice, water, cover and shake. If you encounter a bottle that is difficult to wash, you can add a drop of detergent to your bottle. Similarly, after three shakes, the sewage and rice are poured out and washed again, and the chili bottles are cleaned.

 

 

 

Why can we use rice to clean cans? This is because the rice itself has edges and corners, so in the process of shaking the bottle, the rice impact on the bottle body will produce a certain degree of friction, can clean off the sticky sauce stains on the bottle wall, and the rice itself contains starch ingredients, but also has the ability to clean and decontaminate, so rice can be easily cleaned with difficult to do. Cans.

 

 

 

This is not reliable.

White shell eggs are more nutritious than red shell eggs?

 

 

 

There are rumors online that eggs in white eggs are more nutritious than those in red shell eggs. But is it really the case?

 

 

 

Reporters in different market groups purchased some white eggs and red eggs, and came to the National Food Quality and Safety Supervision and Inspection Center for testing. The average value of the test results of multiple groups of samples showed that the protein content of white-shell eggs was 13.0 grams, the fat content was 7.9 grams and the cholesterol content was 177.4 mg per 100 grams of eggs. Red shell eggs contain 13.2 grams of protein, 7.5 grams of fat and 196.3 milligrams of cholesterol. What does this mean?

 

 

 

Liu Qingchun, chief nutritionist of the Chinese Armed Police General Hospital, said: "In terms of protein, this white-shell egg should be slightly lower, fat slightly higher than the red-shell egg, this gap is very small, almost negligible, cholesterol between the two almost the same."

 

 

 

In that case, why do the eggs appear in two colors, the red shell and the white shell?

 

 

 

Ning Zhonghua, professor of animal science and technology at China Agricultural University, said: "This is mainly related to hens and a substance called protoporphyrin. If the hen can form protoporphyrin, it can produce red shell eggs. If it doesn't produce protoporphyrins, hens lay white eggs, so it's related to the breed of chicken. The main source of nutrients in eggs is what the hens eat and what nutrients are converted, because nutrients are converted from the food they eat, so whether it is a red-shell egg or a white-shell egg, its basic nutrients have no essential difference.

Can't the oranges and milk be eaten together?

 

 

 

Internet rumors have it that the protein in milk is easy to react with citric acid and vitamin C in oranges, coagulate into pieces, not only affect digestion and absorption, but also cause abdominal distension, abdominal pain, diarrhea and other symptoms. Is this true?

 

 

 

Reporters came to the Ministry of agriculture milk and dairy products quality supervision and inspection center to verify it. After mixing 50 milliliters of orange juice with 250 milliliters of milk, the researchers examined the milk carefully and found no obvious precipitates in the milk, nor any solid substances hanging on the wall.

 

 

 

If you increase the amount of oranges, will there be different results? In this experiment, 250ml milk and 10 oranges were selected to do the equal proportion experiment. Compared with the first experiment, some fine particles were observed on the wall of transparent test tube.

 

 

 

Subsequently, the experimenters carried out a third upgrade experiment with 20 oranges. This time, a clear layer of granular material appeared on the wall of the test tube, like a thin gauze covering the glass surface. With the increasing use of oranges, precipitates do appear in milk, so what is this substance?

 

 

 

Zheng Nan, deputy director of the Dairy Product Quality and Safety Risk Assessment Laboratory of the Ministry of Agriculture, said: "This substance is the precipitate of casein in milk. Protein precipitation in milk is related to environmental conditions. When its acidity increases gradually and reaches the isoelectric point of casein, it will precipitate. In our experiments,
