"Hey, I really didn't expect that my sister, who has always been very strict, would still release the water one day. Pen Fun Pavilion www.biquge.info"

"Don't say that my sister is unkind, in fact, my sister has to thank you. ”

Su Yishui looked at the top of the table, and inside the two round containers, there was a piece of clotted fat, as crystal clear as jelly, exuding bursts of fragrance.

Inside, there is the smell of sweet pears and the smell of green apples, which smell so good.

"Why do you want to thank me? Sister, I'm waiting to be trained. ”

"Actually, that's what happened. Su Yishui introduced the details at that time, and when he heard that he needed more than 400 pieces of printer paper, he was also shocked, thanks to his sister's urgency and his own negligence in work, so he didn't let his pocket break the bank.

"Is this fragrant cement? How is it like jelly? Is it just after juicing it?"

Su Yishui picked up a small bowl and was about to take a closer look, when Li Xiang hurriedly ran over, as if protecting his own child.

"Hey, don't move, don't move, wait until it's solidified, and then the smell will dissipate." ”

"Ahh Su Yishui agreed, and carefully placed the small bowl on the platform.

"What is this? Incense cement? I've never heard of it. ”

"yes, Professor, what's that?"

As the name suggests, it is a muddy substance with aroma, using a specific substance to condense the ingredients with aroma, and it can be used after drying, similar to perfume, but the aroma is not so heavy, it can be volatilized slowly for a long time, not as fast as perfume, this is the kind of thing. ”

Su Yishui broke out in a cold sweat, and the more he listened, the more he felt, what he said was the same substance as the deodorant. A substance that is placed in the bathroom for a long period of time. I can't let my sister know about this kind of thing.

"Can you just use the juice that comes out to have this aroma?" asked Su Yishui, who asked with a nose, the air filled with fruity aromas, the aroma of green apples and sweet pears mixed with each other. Condensed into a new aroma.

"Of course, if it's just fruit juice, it won't have that effect, but the chemical industry has long produced aromatic substances extracted from fruits, so if you add them. The effect is completely different. Li Xiang took out two small bottles from a shelf, gently pinched the rubber head, and dripped out a drop of liquid.

It looks colorless and odorless, but when it hits the ground, it is fragrant.

The sweet fruity aroma immediately fills the nostrils, and the person feels as if he has become more energetic.

"Well, feel this again. Li Xiang squeezed out a drop of the pale yellow liquid in the other bottle, which also exuded a rich and sweet smell, which was better than the taste of sweet peaches.

"Fruit juice is the use of fruit extracts to enhance the aromatic taste. Make it closer to the taste, and in the chemical industry, this method is also applicable, as long as you add some of these substances to it, then the aromatic aroma can be greatly improved by a level, such as this small bowl, only need to add a test tube, then the effect will be completely different. ”

"So that's where the aroma comes from, so why bother putting in juice when this chemical can achieve that effect?" asked Su Yirou.

"There are two reasons for this. First, although the aroma contained in the juice itself will escape quickly, this effect is far from being achieved by extracting to ensure the original taste. The second point is for the sake of cost, just using extracts, the cost is relatively high, and if the two are mixed one to one, then the cost will be reduced. ”

"Oh. I didn't expect the professor to give us my sisters, and it's so stingy, it seems that you should have a few less bills in your wallet. Su Yirou said coldly.

"Oh, hey, don't adults remember villains, advisor, you don't take this kind of thing to heart. ”

"What would you do if I were to say I was going to miss me?"

"Sister, forget it. As for the fragrant cement, leave it to the professor to enjoy himself, we don't want it. Su Yishui waved his hand repeatedly.

"Hey, why, it tastes and smells good. Su Yirou sniffed again, how fragrant and pleasant the smell was, why didn't my sister want it.

Su Yishui was already blushing to the root of her ears at this time, how could she be embarrassed to say that this kind of thing would be used in the next few years, not to mention, it was obviously so cheap and not worth it.

"Say, sister, are you allergic to this smell? I see your face is red. Her sister looked at her.

"Really? yes? ah, well, maybe, haha... Su Yishui smiled awkwardly.

"In that case, then I'll ... Su Yirou looked at the several fruits on the side.

Su Yishui wished she would have said something she didn't want, but after staring at her for a while, her sister said something that surprised her.

"I'm going to have strawberries, Sister Strawberry shouldn't be allergic. I've never heard of my sister being allergic to fruits. Su Yirou muttered quietly.

"It's not surprising that the substances that can produce allergies are contained in the tissue fluid before extraction, so even if there will be allergic symptoms, it is very small, which is not the same as eating fruit allergies, so only after the simple extraction of substances will there be allergic reactions, everyone's genotype is different, and the physique is not the same, so even if it is a twin, there is a difference, right?"

"Uh-huh. Since my sister is allergic to apples and sweet pears, Professor Li, you can make me a strawberry and then make it into the raw material for incense, okay?"

Incense? yes. Why didn't I think of it?

"Okay. Li Xiang agreed very happily, he picked up some strawberries and put them in the juicer, beat them into juice, then took out a bottle of mysterious liquid, and brought a small crucible, wiped it clean, and then took a liquid from the shelf on the other side that was very similar to the color of the juice squeezed out, and put it on the platform, ready to go.

He first took out a part of the squeezed juice and put it in the crucible, then squeezed out some of the mysterious liquid and dripped it on the juice, and immediately, some faint mist appeared on the juice, which was ethereal and fluttering, and formed a looming film on top of the juice.

Li Xiang stared at the progress of the film, and when it was about to condense, he took out part of the juice from another bottle, and when he took it out from the straw, a sweet smell permeated the air, the same as the taste of strawberries, but more fragrant and sweeter.

"Strawberry extract?"

"yes. Li Xiang replied.

"Why is it so sweet? I don't feel it when I eat strawberries. ”

"Do you say, are the leaves green or red?" Su Yirou did not answer her sister's question directly, but adopted a step-by-step approach.

"It's green again, it's red again, green because it's chlorophyll, red it's anthocyanins, and when the chlorophyll dissipates, the role of anthocyanins is revealed. ”

"That's right, it's the green that comes from the blue and the blue from the blue, that's the reason, no matter what kind of fruit is tissue fluid, there is more water, so it can't be reflected at all. Li Xiang dropped the extract into the liquid that condensed into a thin film, stirred it lightly a few times, and then, took an alcohol lamp, put the crucible on the tripod, and began to heat it, stirring while heating.

After a few minutes, the liquid condensed into a powder, and the content dropped by half. Only a small amount of powder curled up at the bottom of the crucible. Li Xiang pulled them out with a glass rod a few times, grabbed the crucible sideways with pliers, and poured the powder on top of a piece of tin foil.

"It's done, this is strawberry smoked spice, when you want it, you just need to heat it up a little. ”

"Well, okay, thank you, Professor. ”

Hawkers, although it's incense, anyway, it's better than fragrant cement.

During this time, it took nearly five minutes.

"Since the two of you come to my humble house today, I'll introduce you to some more good things. Li Xiang and the two sisters walked out of the inner room and came to the vicinity of the test bench, where the shelves on both sides were full of test tubes, containers, and books of various materials, and the liquid in the glass cover in the middle was naturally the most eye-catching.

You don't need to say much, you just need to sign, and you can connect with each other.

"You all know the latest mellow fragrance series products of the Moth Mei series, and today, I will introduce you to this recipe and raw materials. ”

"There is also the application of refining and purification technology, which should also be explained to us, Professor Da. ”

"Good. Li Xiang agreed, opened the glass cover, and took out the bottle of brightly colored liquid.

"Shelley uses the perfect combination of classical beauty recipes and modern craft products as a marketing method, therefore, under the instruction of Mr. Zhao, our laboratory has been painstakingly developed and refined, and finally formulated this new product, mellow fragrance series. ”

"What is its effect?" asked Su Yirou.

"Moisturizes the skin, prevents aging, improves the health and vitality of the skin, and at the same time, it has a brightening effect when used for a long time. Li Xiang fixed the test tube on a tripod, clamped it with a clamp, and then lit an alcohol lamp underneath.

The fateful moment began, and although the two sisters had heard of mellow, they were ambiguous, or rather ignorant, about what it looked like and what it smelled like. He did this, but he really satisfied his curiosity.

"Professor, if you heat it up like this, won't this exhibit be ruined?"

"It's okay, it's actually specially prepared for the presentation to you, and I can continue to reconfigure it after the spoils. (To be continued.) )
