Can you eat Songhua preserved eggs if they smell Can you eat Songhua eggs if they smell bad

If the pine preserved eggs are stinky, they are generally not allowed to be eaten. Songhua preserved eggs will carry a certain odor in the process of processing, but if there is a smell, it may be caused by too long storage time and improper storage methods, which will destroy the nutrients in Songhua preserved eggs and may also lead to bacterial breeding. If you eat it blindly, you may experience uncomfortable symptoms such as diarrhea, abdominal pain, and even food poisoning.

When choosing pine preserved eggs, it is recommended to choose products within the expiration date and choose fresher pine preserved eggs to avoid ingestion of harmful substances.

Preserved egg. Also known as preserved egg. When you knock off the outer layer of mud on the outside of the pine egg and peel off the shell, a layer of blue-brown, translucent egg whites is revealed.

Take a closer look, is there still embedded in the protein? The beautiful pine leaf-like crystalline pattern is called a pine flower. Songhua eggs also get their name.

However, where do the pine flowers on the pine flowers come from? It turns out that the pine flowers on the pine flower eggs are carved through a chemical reaction: the main chemical component of the egg white is a protein.

When eggs are left out for a long time, some of the proteins in the egg whites will break down into amino acids.

amino acid）。The chemical structure of amino acids is interesting, it has an alkaline amino group and an acidic carboxyl group.

Therefore, it can interact with both acidic and alkaline substances. When people make Songhua eggs, they deliberately add some alkaline substances to the mud, such as lime and potassium carbonate.

sodium carbonate, etc. They pass through the pores in the eggshell and run into the egg to combine with amino acids to produce amino acid salts. These amino acid salts are insoluble in proteins, so they crystallize in a certain geometric shape.

The beautiful pine flowers are the crystals of these amino salts. In fact, the yolk of Songhua eggs is blue-black, which is also caused by a chemical change: the main chemical component of the yolk is another protein, which contains sulfur.

Over time, the egg yolk will also decompose into amino acids, and release a very smelly gas hydrogen sulfide.

h2s）。Egg yolk itself contains many minerals, such as iron, copper, zinc, manganese, etc., with which hydrogen sulfide can form sulfides. The yolk turns blue-black because of the sulfides.

However, most of these sulfides are extremely difficult to dissolve in water, so they are not absorbed by the human body. In addition, because there are many proteins in the yolk of Songhua eggs that are broken down into amino acids, the yolk of Songhua egg tastes much fresher than the yolk of ordinary duck eggs and eggs. I often hear people say that Songhua eggs can not be eaten, in fact, the main concern is that Songhua eggs contain heavy metal lead (lead), but do not need to be too frightened, as long as you pay attention to check whether there are black spots of different sizes on the surface of Songhua eggshells when buying, if there are them, avoid eating.

Songhua eggs are nutritious and delicious, but they are more alkaline, so they should not be eaten more. Some people like to add some vinegar when eating Songhua eggs, vinegar can sterilize and neutralize part of the alkalinity of Songhua eggs, you might as well try it.

Preserved egg. A lot of protein in egg whites and yolks is broken down into amino acids.

Therefore, the yolk of Songhua egg tastes much fresher than the yolk of ordinary egg. Although Songhua eggs are nutritious and delicious, they are too alkaline, so they should not be eaten more.

Songhua eggs themselves have a foul smell, and the main chemical component of preserved eggs is protein, which contains sulfur. Over time, it decomposes into amino acids and emits what we usually call rotten eggs--- a gas that smells like hydrogen sulfide.

This does not affect consumption. If the preserved eggs are spoiled and stink, they cannot be eaten because of the serious microbial contamination and the increase of pathogenic bacteria.

and the opportunity for the existence of toxin-producing bacteria, and can enable some bacteria with weak pathogenicity to grow and multiply in large quantities, resulting in foodborne diseases after human consumption.

And in the process of spoilage, toxins will be produced, which can easily lead to food poisoning.

How to choose preserved eggs:

1. Put the preserved eggs in the palm of your hand and gently pinch them, the good quality preserved eggs vibrate greatly, and the quality of the non-fluttering preserved eggs is poor;

2. Take the preserved eggs by hand and shake them next to the ears, the good quality preserved eggs have no sound, and the poor quality ones have sounds; And the louder the voice, the worse the quality, even the bad or rotten eggs;

3. Look at its shell, with the eggshell intact, gray-white, and no black spots as the top grade; If it is a cracked egg, it is often possible to infiltrate too much alkali during processing, which will affect the flavor of the egg white, and bacteria may also invade from the crack, causing the preserved egg to deteriorate;

4. If the preserved egg is pickled, the egg white is obviously elastic, brown-colored and has a pine branch pattern, the yolk is black-green or blue-black around the periphery, and the center is orange-red. Poor quality preserved eggs have a pungent foul odor or a musty smell.

Today, there is a brief introduction to can you eat preserved eggs when they are stinky, and for how to identify spoiled food and other food contamination tips, please also learn more about food safety on Baibai Safety Network.

knowledge, I hope it will help you.
