Today, vegetable oils are more commonly consumed and the variety has increased.

Shen Kuo said in his "Dream Creek Writings": "Today's northerners like to fry things in sesame oil, regardless of what they are, they all fry them in oil. ”

And Zhuang Jiyu's "Chicken Rib Weaving" also said: "The oil passes through the Quartet, and the edible ones are natural, but the flax is the top, and the vulgar call fat and hemp, and it is said that its sex is eight awkward, saying that it is thin harvest when it rains, and the big drought is ripe, the flowers are downward, the knots are up, the oil can only be produced by frying and scorching, the ointment car is slippery, and the drill needle is astringent."

And Hedong eats hemp oil, which smells like a raincoat and can be used as a raincoat. Shaanxi also eats almonds, red and blue flower seeds, and cranberry seed oil, and also uses them as lamps, but the porridge is smoked to blind the eyes, and it is not heard of now.

Shandong also uses Xanthus as oil, which is beneficial to the wind.

The rivers and lakes are less flax, more to tung oil as the lamp, but the smoke is thick and dirty, the portrait is especially afraid of it, the clothes can not be washed, the winter melon can be cleaned, the color is green and the taste is sweet, the mistake of eating it, it makes people vomit diarrhea, drinking or tea can be cleaned, covering the southern wine in the gray er, there are women who mistakenly take the ointment hair, the bond is like a vertebrae, and the hundred cures can not be solved, and it is actually gone.

There is also the oil of the pun, its root is black medicine, the people of the village take it as an anointing fire, its smoke is particularly smelly, so the city rarely uses it. Black cypress oil is like fat, can be filled with candles, Guangnan is used, and there are also in Wuzhou. ”

According to Shen Kuo's book, there are eleven kinds of vegetable oils, and there are as many as five or six kinds of vegetable oils used in diet.

According to the classics, it has been proved that there are various plant seed oil yields and oil-making methods, including the squeezing method and the two-wok-boiling method, namely the water substitution method, the grinding method, the scooping method, etc., which basically have the type of edible vegetable oil and the oil-making method with moderate thickness.

In the history of this land of the Central Plains, since the emergence of vegetable oils and their use in diet and other aspects. Animal oil is not completely excluded. The two go hand in hand.

However, due to the many types of vegetable oil, the yield is large, and the use is wide. As a result, the proportion of its consumption is increasing, and it is still ......

Because edible oil is a fatty substance, it has the functions of flammability, water insulation, lubrication, etc., so it is widely used in daily life in addition to being mainly used in diet.

In addition to eating, it is also widely used: the first is used as a burning substance, and it is used for lighting. Manufacture of candles and lamps.

The second is to make waterproof utensils to protect against rain. Such as umbrellas, canopies, etc., most of them are processed after soaking in oil today.

The third is to be used on a large scale in shipbuilding to lubricate equipment. Those large equipment used in shipbuilding formally rely on various oils for lubrication, so that they can be used for a long time and are easy to apply.

The lubrication of the fourth type of car, in the current operation of various places, the amount of various oils used every year, according to the situation that Liu Xing knew before, can even be enough for all the soldiers and civilians in Shandong Province to eat for three years. In the current standing traffic to take the royal car, the grease is the lubrication of the axle in the car.

The fifth is to make skin care and cosmetics for women. Liu Xing is not a woman, but it is also from the mouths of Yanling, Yang Ling'er and those female guards. I have heard that cosmetics made of certain oils have skin care effects.

The sixth is also the most familiar use of Liu Xing, that is, for medicinal purposes. Treat the disease with lipids or oils or in combination with other medications. Especially for the treatment of skin diseases, Liu Xing has not used it himself before.

The seventh is for other uses, such as smearing the inner walls of pottery with grease to prevent leakage, and so on......

He already had a deep understanding of these in his heart, so when Liu Xing heard that someone here was actually changing farmland to grow soybeans and extract oil, he immediately thought of a word and strategic reserve.

Nowadays, the army of the Great Song Dynasty has always used tung oil and food oil as the main fuel for siege and defense of cities. For example, the oil used on the airship is the charcoal essential oil "original" by Liu Xing.

In terms of cost, tung oil is the cheapest. In terms of efficacy, charcoal essential oil has the highest energy.

However, tung oil needs to cut down tung trees, and for a person who has been plagued by haze, Liu Xing is very disapproving of cutting down dense forests at every turn. Only when the forest is cut down will there be haze, so Liu Xing has begun to deliberately reduce the combat reserve of tung oil.

The cost of charcoal essential oil, one pound of charcoal essential oil can be used to produce five catties of sesame oil and ten catties of soybean oil. The technology of charcoal essential oil is a secret that only the Hunter Valley Liujia Charcoal Oil Workshop has exclusively not passed on, so in addition to using it on the airship, Liu Xing does not dare to let go of the wide promotion and use at all.

In this way, in fact, the most cost-effective oil that can really be used as war reserve oil is naturally vegetable oil. Because animal fat oil has to be killed, the cost is much higher than that of vegetable oil.

Among the vegetable oils, soybean oil in later generations is all over the ground, and that scene is the biggest reason why Liu Xing decided to ask clearly first, so as to determine the biggest reason for vigorously supporting the soybean oil processing industry......

Lu Mingtao, who used to lurk in the household department as a secret agent, was a grain business in his own right, so he was particularly concerned about grain and oil when he was in the household department.

When he heard Liu Xing's question, he immediately turned around and came to Liu Xing, lowered his head and hugged his fists and said: "Taifu, although it was a war last year, the total output of soybean oil in Henan, Shanxi, Shaanxi, Dongchuan and Xikang reached 9 million catties. In Hebei and Shandong, last year's output should also be above one million catties. In other words, the actual yield of soybean oil in the whole of last year was between 1,000 and 12 million catties. ”

After listening to Lu Mingtao's report, Liu Xing lowered his head and secretly calculated: 12 million catties, according to the calculation that a family of five eats 30 catties per month, this 12 million catties of soybean oil can meet the edible oil needs of 20 million people.

The entire Northern Dynasty now has a population of 30 million, which means that there are at least tens of millions of people who rely on high-cost animal oil and other high-priced vegetable oils to live.

Oil is a basic daily necessities, and in the case that soybean oil cannot meet the needs of the whole people as much as possible, it will inevitably cause the price of soybean oil, which is not high, to be inflated, and then become a kind of inflation......

Thinking of this, Liu Xing looked up at Lu Mingtao and asked, "Today, what is the price of soybean oil in various places, do you know?" ”

After answering the question, Lu Mingtao already knew this very well, and immediately said: "Yu Taifu, Henan has a good yield of this oil, and it is between 200 and 240 yuan per catty. The output of Shanxi and Chuankang is not low, but the price of the market is often between 300 and 400 yuan. As for Hebei and Shandong, as far as their subordinates know, their prices should be around 500 yuan. ”

Five hundred yuan, as soon as he heard this price, Liu Xing "chuckled" in his heart, and said secretly: I went to his uncle's, the cost of one pound of soybean oil was definitely no more than fifty yuan according to the previous currency, and it could be sold for ten times the price in the market. No wonder, no wonder that farmer is going to give up planting rice millet and switch to soybeans, which is really profitable! (To be continued.) )
