After rebirth, I went from a peasant girl to the richest man

"Hahaha, Miss Bai is smart. Not only does she have novel ideas, she also has some skills in solving cases!"

Then he stopped smiling and said seriously, "Yes, after many investigations by doctors in the city, it was found that the people who were poisoned all bought preserved eggs from a few of these shops and thus developed these symptoms. My father was afraid that they were poisoned, so he brought the people who were doing the preserved egg business to the government office for interrogation."

"but……"

"But those families did not poison the food!" Bai Qingyun replied.

Zhu Yu was somewhat surprised by Bai Qingyun's answer: "Miss Bai, do you know the reason?"

Bai Qingyun had not witnessed it with his own eyes, so he could not give a definite answer. He could only guess and said, "The formation of preserved eggs is a series of chemical reactions. Take wood ash for example. The strong alkaline components in the wood ash penetrate into the egg yolk and egg white through the eggshell, neutralizing the protein and amino acids in them to form some new compounds. These compounds cause the protein to coagulate, forming the unique taste and flavor of preserved eggs."

As he was talking excitedly, he saw Zhu Yu, Bai's father and others looking at him with confused faces, just like himself when he was studying advanced mathematics.

Perhaps because he felt empathy, Bai Qingyun changed his words to a more understandable one.

"In simple terms, many conditions are required for eggs to become preserved eggs. During the formation process, the quality of the eggs, the temperature, etc. will affect the taste of the preserved eggs. Once the preserved eggs go bad, toxic substances will be produced inside. If people eat them, they will have poisoning reactions, such as vomiting, diarrhea and other symptoms."

"I see. I never thought a local snack could hold such a secret!"

Zhu Yu immediately thought: "Wouldn't that be an injustice to those families?"

Then, with a look of regret on his face, the accompanying servant came and prepared to send someone on a fast horse to deliver a letter. If his father had wronged the people during his tenure, it would not be good for either the people or his own reputation as an official.

Just as Zhu Yu was about to give orders, he was stopped by Bai Qingyun.

“Don’t worry, Master Zhu! Although the poisoning of preserved eggs is not entirely caused by human intervention, human intervention cannot be completely ruled out. If the merchants use rotten eggs to make preserved eggs, it will also endanger people’s health after eating them!”

When making preserved eggs before, Bai Qingyun told Xie Shuer to pay attention to the quality when buying eggs, especially in the hot summer. In the absence of a refrigerator or ice, eggs left for a long time will become rotten eggs.

Once a rotten egg becomes a rotten egg, it is unlikely to successfully become a preserved egg because fresh eggs are needed to produce good gelation and flavor changes in the process of making preserved eggs.

Rotten eggs are likely to have gone rotten and spoiled, and the protein and nutrients in them have undergone adverse changes, which will affect the production process and quality of preserved eggs.

Even if rotten eggs are used to make preserved eggs, the final product is likely to have an odor and a bad taste, and may even be harmful to human health.

Because rotten eggs may contain harmful bacteria and toxins, these substances may not be completely removed during the production process and thus remain in the preserved eggs.

There are many ways to distinguish good eggs from rotten eggs among the people. The simplest way that does not damage the eggs themselves is to shake them and listen to the sound.

Put an egg between two fingers and shake it near your ear. Fresh eggs actually don't make any sound. Rotten eggs make a crumbly sound, eggs with large holes make a hollow sound, cracked eggs make a snapping sound, and eggs that make a watery sound are eggs that have been left for too long.

As long as everyone can tell the difference, it is not ruled out that some people deliberately use rotten eggs to make preserved eggs.

Just like the catering industry in the modern dimension, when takeout enters our lives, many unscrupulous businesses will add chemicals to expired or spoiled food and sell it to consumers.

Some businesses even go out of their way to purchase this type of food, under the pretext of: controlling costs!

The government will certainly not let off those merchants who deliberately use rotten eggs to make preserved eggs easily.

It is not difficult to distinguish them. Since these merchants have been arrested by the government, they will definitely leave the preserved eggs as evidence. Merchants who deliberately use rotten eggs to make preserved eggs will definitely have spoiled and poisonous preserved eggs in their hands, while those that are spoiled due to high temperature and other conditions are rare!

Bai Qingyun explained the ins and outs of this matter to Zhu Yu in detail, hoping that no innocent people would be arrested by mistake, and no unscrupulous merchants would be let off.

Zhu Yu nodded repeatedly after hearing this: "Thank you Miss Bai for clearing up my doubts. I'm afraid it's hard to explain the ins and outs of this in a few words. I have to go back to Qujiang County to explain the situation to my father! But..."

"Don't worry, Mr. Zhu. I will give the things you need to Shopkeeper Xu later. I can talk to Shopkeeper Xu about the details!"

Bai Qingyun picked up the tea on the table. He was tired of eating the cakes, so Manager Xu thoughtfully prepared some tea for him to help him get rid of the greasiness.

It’s not hard to guess what Zhu Yu’s request was. He came just for the preserved eggs.

The poisoning cases of preserved eggs are probably just incidental, and ultimately they are caused by the preserved eggs that people made themselves.

If you need preserved eggs, just tell Shopkeeper Xu and Bai Qingyun will make a large amount of them and pass them on to Shopkeeper Xu.

But Zhu Yu came here in person, probably for the secret recipe of preserved eggs!

If you want to make preserved eggs delicious, you need some skills. Different flavors of preserved eggs taste different.

Take naturally ripened preserved eggs for example.

Naturally ripened preserved eggs do not need to be boiled and can be eaten directly after peeling the shell, and they have excellent flavor.

That is incomparable to the boiled preserved eggs.

Before buying Bai Qingyun's preserved eggs, Zhu Yu compared the preserved eggs from many stores in Qujiang County before deciding to buy the ones from Bai Qingyun.

I think many of the ones I bought before have been sold out, but I don’t know whether people will still be as popular with preserved eggs as before after the poisoning incident in South City.

Now I don't want Sister Shuer to repeat the mechanical work of selling eggs and making preserved eggs every day. Instead of supplying eggs to Zhu Yu for a long time, it is better to sell the secret recipe directly.

But the preserved egg business was so tempting that Bai Qingyun was reluctant to sell it directly, so he said to Shopkeeper Xu: "Uncle Xu, you can sell the secret recipe to Mr. Zhu, but today I will only sell the secret recipe..."

The food recipes previously sold to Hongyunlou were bought directly by Manager Xu.

This means that the Bai family will no longer be able to sell this recipe.

The Bai family had no plans to open a restaurant, and even if they did, they didn't plan to sell those dishes, so they sold them at a high price.

But Bai Qingyun has his own business ideas about the preserved egg business, and he will only sell his secret recipe to Zhu Yu. At the same time, Zhu Yu cannot stop Bai Qingyun from doing this business in the future!
