After the bright milk powder was produced, Marin sent a few bags to each of his nobles, which could be regarded as advertising in advance. After all, in this era, it was the aristocracy that led the way. In the absence of celebrities, the lifestyle of the aristocracy is the object of imitation and imitation by the whole society. Of course, civilians can only imitate what is in accordance with the rules, and some arrogant things cannot be imitated casually.

Of course, there are no rules for eating, as long as you have the money to buy it, you can eat whatever you want - except human flesh......

Something like milk powder is actually the powder after milk has been dried, and there is no technical difficulty. Anyone else can figure it out just by figuring it out.

Marin certainly knows this, but he's not worried about having a competitor. Why? Because other people don't know how to seal and preserve milk powder......

According to the rules of later generations, it is best to drink 400 grams of milk powder within two weeks after unpacking. Otherwise, the milk powder is easy to spoil by bacteria.

Therefore, if the general milk powder is not done well in sterilization and sealing, the milk powder will be bad within a month. And after Marlin is sterilized and sealed at high temperature, it can be stored for a long, long time.

According to the standards of later generations, the shelf life of milk powder is generally 18 to 24 months, and the longest can even reach 3 years. However, Marin felt that with the soil technology he was currently making, he might not be able to preserve it for that long. After all, he didn't add any preservatives. Therefore, Marin decided to set the shelf life of milk powder at 1 year. In this way, it can also be safer and avoid accidents.

But even so, such a long shelf life is very scary. You know, fresh milk has a shelf life of only three days. If you don't drink it in time, it will go bad. It's scary to drink bad milk, and it's not negotiable to have diarrhea......

Therefore, for the shelf life of milk powder for up to one year, Marin's subordinates expressed enough surprise. Especially Schwartz, he keenly discovered that milk powder has such a long shelf life, it can be used as military supplies...... Of course, under the current conditions, it can only be used as supplies for officers. As for ordinary soldiers, they are not yet extravagant enough to let ordinary soldiers drink brewed milk powder......

The reason why Schwartz believes that milk powder can be used as a material for military officers is not only the long shelf life of milk powder, but also the convenience of it.

Although Earl Grey milk tea is delicious, it needs to be boiled. Only those who have enough leisure time can wait slowly for milk tea to be boiled. Moreover, tea is now also dead expensive.

But milk powder is different, as long as you boil water and brew it directly, you can drink it quickly. Moreover, after adding sugar, the taste of milk powder is even better than wine.

There is also a problem - during the war, it is better for officers not to drink alcohol, so as not to delay the fighter. However, as an officer, you can't drink boiled water, it's too bad. Therefore, this kind of milk powder that can be brewed has become the best drink for officers when they are usually thirsty - delicious, easy to preserve, easy to carry and use, and is there a more suitable drink for officers than milk powder?

Marin expressed a high degree of agreement with Schwartz's suggestion. Of course, this is only in wartime when abstaining from alcohol. European mercenaries, accustomed to drinking. If they were to be banned from drinking, it would have been a backlash. Therefore, Marin did not prohibit officers and soldiers from drinking in peacetime, but it was strictly forbidden for them to get drunk. In normal times, it is nothing to let the soldiers drink some beer, which is the national drink of Germany.

However, during the war, it is easy to get into trouble when drinking. Marin led his troops on several occasions, and when he was fighting, he was forbidden to drink. Schwartz also went on many expeditions and knew the difficulties of the soldiers. During the war, it was nothing to let those soldiers drink boiled water, anyway, the soldiers had a low status and no human rights. But those officers with good backgrounds, let them drink boiled water, and those officers will feel embarrassed. Therefore, it is necessary to find a non-alcoholic beverage for them. The characteristics of milk powder that are resistant to preservation, carrying, and easy to use have become the first choice of wartime officers......

……

Marin also had no opinion on this, and approved Schwartz's suggestion, intending to come up with a batch of milk powder as a special supply for wartime officers. However, in order to prevent the milk powder from spoiling, Marlin specially used a 400g package. Because, if the package is too large, it will take longer to drink after unpacking, and it is easier for the milk powder to deteriorate. And the 400-gram package is just right, unpacked, as long as you drink it all within two weeks, it's just right.

So, Marlin used a 400-gram package and noted on the oily paper bag - "It is best to drink it all within two weeks after opening it to avoid spoilage".

In fact, Marlin prefers to make coffee a military beverage. Because, coffee can refresh the mind, and during the day, it is good for officers to drink coffee.

However, for the time being, the cultivation and production of coffee is monopolized by the Arabs. It wasn't until 1570, when the Turks were besieging Vienna, that a bag of coffee seeds was left behind when they retreated, allowing the coffee to flow to Europe. Therefore, it is difficult for Marlin to get coffee even if he wants to, and even if he does, the price is very expensive. Because, in the Arab region, coffee is also used as medicine......

The problem of tea is similar to that of coffee, tea is now far away in China, and even if it is successfully introduced, it will take several years to grow and provide products. Therefore, at this stage, milk powder is really the best military drink, which is specially supplied to officers......

However, for the sake of future development, Marin decided to not only go to Daming to get tea seeds, but also to get coffee seeds.

For this reason, Marin decided to send spies to the Arab region to privately buy coffee seeds at a high price. Then, it is taken to the tropical regions of the Americas for cultivation. Turkey was hostile to Europe, but the Mamluks in Egypt were not so hostile to Europe. As long as you send someone to Egypt and spend a lot of money, you can still get coffee seeds. As for tea, there is no need to talk about it, as long as the trade of the Ming Dynasty is opened, it is still easy to get. As long as you can get on the land of Daming, you can privately offer a reward of 1,000 taels of silver, and some people are willing to offer tea seeds, and you can even get some tea farmers.

Marin intends to occupy the island of Taiwan as a foothold anyway, and the climate and topography of the island of Taiwan are just right for growing tea. The requirements for tea are just that they are hilly, subtropical or tropical, with enough precipitation and good drainage......

It just so happens that the island of Taiwan is very suitable for the conditions - the terrain on the island is undulating and there are many hills, which is very suitable for growing tea. In later generations, the oolong tea and high mountain tea of Taiwan Island were very famous......

When tea cultivation on Taiwan Island develops, it will be absolutely smooth sailing to bring tea seeds and tea farmers to the Americas to open up new tea plantations.

In short, Marin wants Europeans to live a good life of drinking coffee and tea every day in advance. It's just that, for now, drinking brewed milk powder seems to be a little more realistic. Therefore, at present, the military beverage that is specially supplied to officers can only be the lowest-cost milk powder...... Well, it's bright milk powder in oil-paper packaging......
