Chapter 135 New Uses for Garlic
Su Yuejian was still thinking about something, and was in a daze. She tasted the food and asked, "What did you say just now?"
"Miss, I said I made some minced garlic and put it in all the dishes when I cooked them. It tasted refreshing and appetizing."
"Appetizer, appetizer, appetizer..." Su Yue's eyes suddenly lit up, as if she had caught something.
"Chunlan, I remember now! It's garlic! Chop the garlic into minced garlic, let it air dry for a while, and then mix it into the pig feed. It will stimulate appetite and is also useful for diarrhea."
Su Yuejian hugged Chunlan excitedly, "You are my lucky star!"
Su Yuejian called Aunt Amber and set aside an acre of land to grow garlic.
“This can not only be used as a dish, it can also cure diseases in animals and can be used as an antibiotic for humans!
Just tell them to do what I just said about the pigs."
This thing is the best medical resource in the end times!
Be sure to make allicin!
This is much easier than penicillin extraction.
Su Yuejian asked Su Quan to go to the Qi family's Zhongli County branch wine shop to get a jar of Yuejianzui.
Su Yuejian first mashed the garlic into minced garlic.
Then add water and distill it. The product obtained after distillation is very small and the effect is unstable.
Is it that water is not a good solvent, or is it that the temperature is not a good temperature?
Su Yuejian adjusted the variables one by one and found the problem.
During the entire extraction process, Su Yuejian discovered that allicin is unstable to heat.
Especially when the temperature rises to 80 degrees, allicin decomposes faster.
The solubility in water is not ideal either.
What solvent should I change?
Su Yuejian thought of using alcohol as a solvent for extraction.
Since allicin is heat unstable, all heating and distillation procedures require strict temperature control.
Fortunately, the kerosene thermometer has been made, otherwise I don’t know how many times I would have failed if I had relied solely on experience to control the temperature.
Other people who participated in the entire experiment included Shaoyao, Baiji, Wang Wenjun, and three medical practitioners who had just come from Renxintang for further studies.
The doctors who came here the first time have already returned to the capital, and this is the second batch of trainees.
Qingmei and Yingluo also came with them.
Now, the four aunts are finally together.
Qingmei can also take apprentices in nursing.
Su Yuejian led everyone to cut the garlic into slices, dehydrate them at a temperature of about 50 degrees for 75 minutes/one hour/three hours/six hours, and then pour in solvents with different alcohol concentrations (95%/%/% concentration).
After seventy-two hours, filter the solution, squeeze out the residual garlic juice from the garlic slices by physical pressing, and then filter it a second time with filter cotton. Finally, distill and recover the alcohol at 40 degrees, 50 degrees, and 60 degrees respectively. The remaining light yellow oily liquid is allicin.
After several experiments in this round, it was found that the group of test products that were dehydrated at low temperature for six hours had the best effect when the liquid was recovered by distillation at 50 degrees with 50% alcohol as the solvent.
But this method takes four days, which is still too long.
于是苏月见又尝试另一种方法，加入95%酒精在30°C/40°C/50°C下萃取半小时/1小时/1.5小时/2小时/3小时，然后控制蒸馏温度在50度。
After this round of experiments, Su Yuejian found that the longer the enzymatic hydrolysis time, the lower the allicin extraction rate.
This may be because the enzymatic hydrolysis time is too long, and the allicin is easily volatilized, thus affecting the extraction rate.
In this round of experiments, Su Yuejian also found that the higher the alcohol concentration, the greater the extraction rate.
The extraction time showed a trend of first increasing and then decreasing.
If the extraction time is too short, the allicin produced will be too low, while if the time is too long, it will easily be converted into other by-products.
In this round of experiments, the key data finally determined were: enzymatic hydrolysis at 40°C for half an hour, extraction at 95°C for 30 hours with 1.5% alcohol, and then controlling the distillation temperature at 50 degrees.
mock up!
No matter how well you hide, I will catch you!
This method is more time-saving than the method used in last week's experiment, and the entire process is carried out at low temperature, which guarantees the extraction rate of allicin to a greater extent.
The results are better than all previous experiments. Although the extraction rate is only a pitiful 0.24%, it is already the best data after hundreds of experiments.
There are no relevant industrial results, and it all depends on traditional methods of extraction. The extraction rate is really touching!
It was hasty to ask Aunt Amber to set aside one acre of land to plant garlic. She needs to set aside at least ten acres of land to plant garlic!
Otherwise, there would not be enough garlic for people to eat, so where would there be enough garlic to extract allicin?
The people who grow the garlic, the people who harvest it, the people who peel it, the people who extract and process it, and the time spent on growing it are all huge costs.
If this is calculated into money, the price of the drug will be so high that ordinary people cannot afford it, and it will become a miracle drug that is worth a fortune.
The rich will definitely be charged; for the poor, the drugs can only be given away for free if they are accessible.
But this is also limited, after all, this thing is very expensive and the output is too small.
Su Yuejian had no intention of making money from the medicines. Even if she wanted to give them all away, they would still not be accessible to everyone due to production and cost limitations.
Back to the topic, allicin is actually a very powerful broad-spectrum antibiotic that can inhibit the growth of many bacteria and fungi.
Its bactericidal ability is 100 times that of the same dose of penicillin.
Such a strong bactericidal effect is mostly used in veterinary medicine as far as I can remember.
Precisely because it is used in veterinary medicine, I have never thought of this great treasure.
Under the current rough medical conditions, it is most suitable for use on humans.
Due to the unstable nature of allicin, it is difficult to effectively extract it using industrial methods, which is also one of the important factors limiting the development of allicin applications.
But for Zhongli, this defect is not so unacceptable compared with its function.
It has not reached the level of industrialization. It is much more convenient to use it on the same day and produce it on the same day than to extract penicillin.
This can also complement penicillin. Penicillin is not easy to mass-produce, but it is still very useful. The extraction work cannot be stopped and drug reserves still need to continue.
Allicin was extracted in the laboratory. This drug needs to be diluted with sodium chloride injection and then slowly dripped, but the physiological saline here does not meet the standards.
Although distilled water can be made pure, it still contains a lot of salt impurities, and the process of preparing sodium chloride injection will inevitably mix in miscellaneous bacteria.
The purity requirements for external use of physiological saline are not that high, but the sodium chloride injection to be dripped into the body must be of medical grade and the purity must be guaranteed.
The technology tree behind this cannot be completed by one person alone, so if this cannot be done, allicin cannot be used for intravenous drip.
