The Persian official then said slyly:

"Then if Scholar Xiang is not right, then I will sell it at a higher price?"

Xiang Yan laughed and said as if chatting:

"Cocoa beans, the fruit of the cocoa tree of the Sycamoreaceae evergreen tree, the flat seeds of the oblong nut, with an oil content of 53%~58%. The cocoa butter has a unique aroma and melting properties. It is a product of the cocoa tree. ”

"Cocoa is not suitable for growing on gentle slopes formed by warm and humid climates and alluvial soils rich in organic matter, but is not suitable for growth on poorly drained and heavy clay soils or in areas that are often hit by typhoons."

After these two sentences, the contempt on the faces of the Persian officials disappeared.

But they also refused to admit defeat easily, after all, they brought a lot of cocoa beans, and any cheaper one was a lot of money.

Xiang Yan didn't care, just continued:

"Speaking of which, I also have some superficial research on cocoa beans, I wonder if the Persian officials know what nutritional value cocoa beans have?"

When several Persian officials heard that Xiang Yan had taken the test for them, they had a look of joke on their faces:

"I want to hear about it."

Xiang Yan nodded:

"Studies have found that cocoa contains oleic acid, linoleic acid, stearic acid, palmitic acid, protein, vitamin A, vitamin B1, B3, B5, B6, vitamin D, vitamin E, minerals calcium, magnesium, copper, potassium, sodium, iron, zinc; Cellulose; Polyphenols. ”

This series of proper nouns was spoken, and the Persian officials were almost stunned as if they were listening to the heavenly book.

But it was not good to interrupt Xiang Yan, so I could only continue to listen to him:

In addition, cocoa contains more than 500 kinds of aromatic substances, and the melting point of cocoa is 35~37 °C, and the taste and texture are endless. I summarize past research findings and find that cocoa has the following eight functions. ”

Finally, when it came to the understandable part, the Persian officials cheered up.

Xiang Yan's words continued.

"One, control your appetite."

Cocoa is rich in cocoa butter, protein, fiber, vitamins and minerals; Nutritionally complete with very few absorbable carbohydrates (less than 10%). Therefore, cocoa is a green light food for lucasin, and eating cocoa is easy to feel full and has little effect on blood sugar.

The linoleic acid in cocoa butter can produce GLA, which is finally converted into type 1 prostaglandins by DGLA, which can dilate blood vessels, eliminate metabolic disorders, and help insulin work, thereby stabilizing blood sugar and controlling appetite.

In addition, research from the Massachusetts Institute of Technology found that cocoa can increase the concentration of serotonin in the brain, thereby stabilizing mood and controlling appetite.

Finally, cocoa is able to increase the formation of nitric oxide, which dilates blood vessels, accelerates metabolism, and helps "leptin" work.

The Persian officials thought about it, although they still didn't understand some of it, but they did feel full after eating cocoa, so what Xiang Yan said should be right.

"Second, beauty and beauty."

Cocoa is rich in proanthocyanidins and catechins, as well as vitamin E, which has a strong antioxidant effect. These antioxidants, together with the vitamin A and zinc in cocoa, are used to beautify the skin, remove acne and scars.

It is possible to remove acne and scars, and the Persian official quickly took out a small notebook and wrote it down.

"Three, increase affection and help 'sex'."

Cocoa can increase the formation of nitric oxide, which promotes the expansion of blood vessels and helps men to become stronger. The principle is the same as that of Viagra.

The Persian officials were suddenly very surprised, but Coco still had such a role?

Write it down and try it later when you get home.

"Fourth, pleasing to the mouth."

This is mainly about the taste of cocoa, which is nothing to remember.

"Five, concentrate on refreshing."

The theobromine in cocoa can make you think sharply and focus. The tryptophan and magnesium in cocoa can help with serotonin production, making you calm.

Persian officials say that although there are still parts that are not understood, it now sounds very reasonable!

"Sixth, reduce fat and protect the heart."

Flavanols and proanthocyanidins are the main flavonoids in cocoa, which can prolong the action time of other antioxidants in the body, such as vitamin E and vitamin C, while also promoting vasodilation, reducing inflammation and reducing blood clot formation, thereby playing a role in preventing cardiovascular disease.

"Seven, clean your teeth and cavity."

Cocoa cleans the mouth and prevents gum calculus and tooth decay. The tannins and polyphenols in cocoa can stop the formation of gum calculus and tooth decay.

And this effect?

Persian officials also said that they would write it down and try it later.

"Eight, prolong life."

According to expert research, as early as 500 years ago, doctors in Western countries used cocoa to treat tuberculosis, anemia, headaches, gastrointestinal discomfort, apathy and kidney stones. It can be seen that cocoa has a long history of health effects on people.

These things stunned the Persian officials, who never imagined that they who were often in contact with such a thing as cocoa would not know as much about it as people from an eastern country where there was no cocoa production!

If it weren't for the lack of a mobile phone and something, they would have to post online and ask how to evaluate it.

"Hahaha, Lord Xiang is worthy of the name of a scholar, a heavenly official, it is really extraordinary, we are willing to gamble and lose, and all the cocoa brought this time will be sold to you at a ninety percent discount."

After reading the first cloth bag, Xiang Yan opened the second bag.

This is a joy.

"Corn?"

"This is corn?"

The Persian name for this thing must be different from Huaxia, so they didn't react much to the name.

But what Xiang Yan said next surprised them.

"Tall herb of the year. The stalks are erect, usually unbranched, 1-4 m high, with aerial pillar roots at the base nodes. ”

leaf sheaths with transverse veins; leaf tongue membranaceous, about 2 mm long; Leaves flattened and broad, linear-lanceolate, rounded and ear-shaped at the base, glabrous or pubescent, with a stout midrib and slightly rough margins.

The apical male panicles are large, and the main and raceme axes and their axils are finely pubescent; Male spikelets are twins, up to 1 cm long, with a long spikelet and a short stalk, 1-2 mm and 2-4 mm long, respectively, and finely pubescent.

the two pinnacles nearly equal in length, membranous, about 10 veins, ciliated; outer and inner barren hyaline membranous, slightly shorter than Ying; anthers orange-yellow; It is about 5 mm long. The female inflorescence is surrounded by mostly broad sheath-like bracts.

female spikelets twin, arranged in 16-30 longitudinal rows on stout sequential axes, two spikelets equal in length, broad, veinless, ciliated; The outer and inner barbs are hyaline membranous, and the pistils have very long and weak linear columella.

The fruit is spherical or oblate spherical, and after maturity, it is exposed outside the slices and slices, and its size varies with different growth conditions, generally 5-10 mm long, slightly wider than its length, and the embryo length is 1/2-2/3 of the fruit. Flowering and fruiting period in autumn.

If the name of corn was said before, it could be seen as a noun fool.

Then go on to say that these things are enough to prove that Xiang Yan understands this crop.
