After having the butt-slide style and sunflower treasure book, the cost advantage has come out, but it is not intuitive. What Tangning needs to do is to vigorously master global agricultural product procurement. No matter how low your cost is, it cannot be as low as those hard-working farmers who use inhumane means such as slaves? So, let’s have something even more amazing - Star-absorbing.

I remember that Tangning’s goal was agricultural products, that is, food, and a big move came to the surface - preservatives.

Some people have misunderstandings about preservatives. They believe that there are preservatives in food and don’t even dare to eat microorganisms, so humans cannot eat them, and they must be poisonous. This is a big mistake. The dung beetle also eats poop. Now even children educated by Tangning know that the food sources of organisms are very different. The dung beetle is already a relatively advanced life, and how can microorganisms be compared with human recipes?

To give a simple example, the digestive tract of humans is highly acidic, which is a fatal environment for most microorganisms. This is the benefit of the precision differentiation of cells in advanced life. Humans have used this principle to invent ways to prolong the storage time of food by using yogurt, pickles, etc. By the same token, there are many substances that humans can ignore but are not friendly to microorganisms.

Of course, if humans are allowed to use various preservatives naturally, it will take a long process, and during this process, some side effects of various preservatives will be slowly discovered. After decades or hundreds of years, more excellent products will eventually be selected.

In the current food industry, the use of preservatives is almost blank, and the only thing that can be stored for a long time is canned food. Excessive amount is harmful. Here is a more intuitive standard, which is table salt. Its semi-lethal amount for experimental animals and rats is 3,600 mg per kilogram of body weight (kill half of the experimental animals, reliable experiments always require large samples). In order to make the canned food better antiseptic effect, a large amount of salt is often needed, which is also unfavorable to human health.

Why do people eat salt? Its molecule is sodium chloride. The transmission of nerve impulses caused by signal conversion is regulated by sodium ions. Once excessive, the nerve impulses in the human body will be disordered. Due to the instinct of animal survival, many animals are greedy for salt because there is relatively few salt in nature. Humans have also inherited this hobby. What is more contemplated is that the human salt making industry has been very developed since ancient times. As long as it is not a war or a monopoly of a strong government, it is impossible to lack salt. Therefore, there is a widespread phenomenon of excessive consumption of salt in humans. As long as humans eat excessive sugar, they can understand why humans eat excessive salt now.

Microorganisms that invade meat and are harmful to humans are mainly Botox. Sodium nitrite is generally used as a preservative and color protector for meat products and fish products. It can inhibit the growth of Botox and prevent Botox toxin poisoning. However, sodium nitrite has a certain toxicity. If the oral sodium nitrite is taken by rats, the semi-lethal amount is about 180 mg per kilogram of body weight. In addition, under acidic and heated conditions, sodium nitrite can react with the amino acids in the meat to produce the carcinogen nitrite amine.

There are certain health risks, but it does not have to be rushed. This is the same as barbecue and kimchi that humans have eaten for tens of millions of years. They have cancer risks. However, within the scope of human ethics and habits, there is no need to be disgusted. Just reduce the number of times these foods eaten within the range of self-control. Think about it, it is difficult for people on the Korean Peninsula to avoid eating kimchi. They probably say: If you don’t have kimchi, you won’t die. Brazil and Argentina will not die if you don’t have barbecue.

Benzoic acid and sorbic acid can inhibit the growth of mold, yeast and certain bacteria, and their salts are widely used in the preservatives of food and beverages. Benzoic acid is low in toxicity, and the semi-lethal amount of rats is about 1,700 mg/kg. However, benzoic acid in beverages can react with vitamin C to produce the carcinogen benzene, especially under heat and light conditions. Sorbic acid has the lowest toxicity, and the semi-lethal amount of rats is 7,360 mg/kg. Sorbic acid is an unsaturated fatty acid that is quickly decomposed into carbon dioxide and water in the human body. Scientists have never found adverse reactions to sorbic acid. Sorbic acid is less toxic than benzoic acid and has a better anticorrosion effect. It can replace benzoic acid and will be the preservative recommended by Downing.

The power of the star-absorbing preservative is the innovation of food packaging, which can be called chemical engineering. Tangning especially likes glass, which is completely recyclable and environmentally pollution-free packaging. However, it is obviously only suitable for beverages, and it is bulky. Food-grade plastic bags are inevitable. Tangning, who monopolizes petrochemicals, can certainly formulate plastic circulation strategies as he wants, or the old rules, use economic leverage for food packaging, and after eating, let the rest be poured clean in the food, and then take the packaging bag to the retailer to enter the recycling cycle. You will get a very cheap packaging box. Otherwise, after environmental publicity, you will feel morally guilty and cannot really pollute the earth. Artificially priced packaging will become the favorite of scavengers, and a packaging will not be wasted.

After Downing briefly talked about these good things to Waldorf, Waldorf was shocked and asked: "How are you confident of handling such complex technological innovation?"

Tangning had to half-truely make up a relationship: "My good friend to Grand Duke Luxembourg, J.P. Morgan." Haha, this sentence is not wrong at all, but now it makes Waldorf think that Downing relies on Grand Duke Luxembourg, and has the opportunity to get in touch with the latest inventions of god-level industrialists at the first time. Tangning just gave himself a false name that was pronounced very close to Downing Windsor: Turing Visa. Turing is known as the father of modern computers, and in this plane, Downing is also the father of computers.

Waldorf has 80% believed in the friendship between "Turing" and Morgan, because what Tangning said cannot be even bragging that ordinary people can imagine. If what Turing said is true, then it feels like the three unique martial arts of Sunflower Book, Star-absorbing and Transformation are all in their hands. Why worry about the big things happening?

The Venetian businessman Waldorf, who has a sensitive business touch, has already smelled a strange smell. Following this young man, he will have a great future!

Although Downing's super wholesale market is a mirage, Waldorf still asked him to go to his grocery store to inspect and ask for guidance.

Just in time, Downing wanted to inspect the people's conditions in various industries in Luxembourg, and see the grocery stores were also good.

Although Luxembourg's economy is booming due to the plan of the European central city of the Grand Duke, to be honest, the current situation is far inferior to that of big cities such as London, and it is not as good as Munich, Zurich, and Brussels. It is somewhat similar to Stockholm, poor and has great potential.

Downing not only inspected Waldorf's grocers, but also looked at many Venetian merchant competitors. The conclusion was that this veteran in the retail industry was quite skilled, very attentive to business, diligent and efficient personality could be seen from the placement of goods, and was obviously better than the competitors. If Downing lived nearby and had a choice, he would definitely come to Waldorf's shop to buy things. No wonder he could make money. However, in the New York Times, the three grocery stores that Macy, who created the department store model, had not been very successful.

Waldorf was kindly invited to Downing to his house for dinner. This was a big wish. This allowed us to see Marlena? Downing's wishful thinking failed. Marlena is now a popular dancer with a lot of social engagements. She also took the opportunity to gain greater benefits. This great opportunity was missed. (http://.).

When Tangning arrived at her house for the second time, he finally met Malena. At this time, Malena was very proud of herself because of the great success of the dance. She looked like a star who became famous overnight. She admired the exquisite illustrations of the savanna card that Tangning gave her, but it was just an interesting little gift. This was enough for Tangning. He enjoyed the different life experiences of changing his identities. In addition to Waldorf, Tangning was just one of the thousands of fans who were fascinated by her.

These days, when Tangning was tired of technical research, he often went to Waldorf's house to have a meal and became a regular visitor to the Marlena's house. What he didn't know was that there was a pair of resentful eyes always staring behind him. The owner of these eyes was the Blood Droplet Master, who had inexplicably had great sorrow for Luxembourg.
