00:00 Before watching the video, I remind you that there is more content on the Hotpoint website.
00:04 Yesterday's report mentioned that the economic value of black water is high.
00:09 Not only does it have the function of eliminating fish,
00:11 it eats white and fat larvae,
00:13 and can be used as an animal feed to feed fish.
00:16 And the feces it eats and excretes can be used as fertilizer in the planting leaves.
00:21 It can be said to be a dragon's economic value chain.
00:24 It is considered to be a insect with a high investment return rate in the circular economy.
00:29 Whether it is the larvae stage or the insect stage,
00:32 black water is full of treasures.
00:35 It can be used in different areas to create a new blue sea of circular agriculture.
00:39 Currently, there are many companies in China and abroad that are starting to study and implement
00:43 pet feed made from black water,
00:46 cosmetics, human food protein and medicine, etc.
00:50 Maximize the economic value of black water.
00:53 Professor Qiu Zhongjun, who is responsible for the research of microorganisms and parasites in the Department of Medicine and Health Sciences of Malacca University, revealed that
00:59 after the experiment, they extracted antibacterial proteins from the larvae of the black water dragon
01:05 to suppress certain components of antibody bacteria against the human body.
01:09 But he said that the drug must be made and the experiment must be completed in order to launch the market.
01:15 However, Professor Qiu Zhongjun found it exciting.
01:21 In addition, he also invested a lot of research in food research and technology in the University of Thailand
01:27 to produce food sources for humans by black water.
01:31 Professor Zhang Lizhu, a professor of science, said that
01:34 now many people cannot understand the choice of insect protein as food for humans.
01:41 They even ask, "We have food now, we can eat it. Why do we have to eat insects?"
01:47 He explained that this is the preparation for the food crisis in 2050.
01:54 After all, climate warming has already happened in front of us.
01:57 Insect protein may be the alternative choice of humans in the future food crisis.
02:03 Let's follow the camera of 8 o'clock Daily's reporter Shen Jiayin, Huang Jieqi and Liu Shengming to go to the two universities.
02:11 (The food research center of the University of Thailand)
02:16 This is the food research center of the University of Thailand.
02:19 The green floor and the layers of the walls are all simulating the interior design of the food factory production department.
02:25 Wow, it smells good.
02:26 This is what I baked this morning.
02:28 Try it.
02:29 It's crispy.
02:30 The cream smells so good.
02:33 If not said, no one really knows that there is a future.
02:37 The special thing about this biscuit is that it has insect protein.
02:41 It contains about 20% of black water caterpillar additives.
02:46 If not said, no one really knows that there is a future.
02:51 This is the black water caterpillar you just ate.
02:55 The raw material in the biscuit has been dried.
02:57 We dry it at low temperature for about two hours to preserve the nutritional value inside.
03:02 The protein in each black water caterpillar is about 40% and 20% of fat.
03:08 It is not saturated with fat, cinnamon acid, duck oil acid, and other healthy oils.
03:14 From the appearance of the black water caterpillar, it is similar to the breadworm.
03:20 The former is wide and fat, and the latter is relatively long.
03:24 After grinding the black water caterpillar into powder, it can be used as a food additive to improve the nutritional value of specific foods.
03:31 They have successfully used black water caterpillar to develop black water caterpillar jerky,
03:35 black water caterpillar chips, and black water caterpillar peanut butter, etc.
03:39 When people hear that insects are added to food, many people may feel resistant
03:44 and even wonder why they have to eat insects when they have no food.
03:48 Zhang Lizhu thinks this is to cope with the food crisis in the future.
03:52 If I ask you, "Are you full today? Have you eaten?"
03:56 Everyone says, "No problem, I have eaten."
04:01 We don't feel that nervousness.
04:03 But in fact, in many urban pools, they are already facing food crisis.
04:10 Now things are getting more and more expensive, food is getting more and more expensive.
04:14 So we are worried that one day there will be a shortage of food and nutrition.
04:18 So we have to start looking for some alternatives.
04:20 Insect protein will have its advantage.
04:25 But insects will not be the main food of the future.
04:28 It is just one of the choices to supplement human social nutrition balance.
04:31 Zhang Lizhu said that now it is too expensive to raise cattle, sheep, chickens and pigs and a lot of crops.
04:38 High carbon will also affect the environment.
04:41 Insect farming costs are relatively low.
04:44 Low cost and high nutrition black water caterpillar can not only become a social balance for some backward children.
04:51 When facing a shortage of food supply, it can also be provided to animal farms for feed.
04:57 Black water caterpillar itself has 40% protein and 20% good fat.
05:03 These are all suitable for animal feed.
05:06 And the research has already been done to tell us that it is effective in increasing the rate of animal feed or their growth rate.
05:16 And we can know that the health of our animals is good.
05:22 And their food supply is also sufficient.
05:24 So we can solve the shortage of food.
05:28 In addition to solving the food crisis that humans will face in the future,
05:33 black water caterpillars are also being used for experiments and development of synthetic drugs.
05:37 Under the guidance of Professor Qiu Zhongjun,
05:40 8.12 is being filmed at the Medical Laboratory of Malacong Medical University.
05:44 This is one of the laboratories.
05:46 This is a PhD student who is studying insect antibody protein called Azmila.
05:50 She is studying the yellow blood in the black water caterpillar through a microscope.
05:56 When we collect the hemolym, hemolym contains the antimicrobial peptide,
06:00 which is responsible for fighting against bacteria.
06:02 They have been fed with materials such as rotten fruit,
06:06 so they develop antimicrobials to protect themselves.
06:08 So that is what we try to get from them.
06:11 Professor Qiu Zhongjun, who is in charge of guiding this PhD student,
06:14 also emphasized that although they found that the antimicrobial protein in the black water caterpillar can make drugs,
06:19 it still needs a lot of experiments to prove it.
06:22 But this discovery is still very exciting.
06:25 According to our preliminary research,
06:28 it is shown that the black water caterpillar has some proteins in its body,
06:33 and these proteins have the antimicrobial effect.
06:37 We tested 10 harmful bacteria,
06:41 including the anti-drug bacteria, which we call MRSA.
06:46 Our preliminary research shows that the protein in the black water caterpillar has some effect on these bacteria.
06:54 So this is very encouraging for us.
06:57 So why did you choose the black water caterpillar as your research subject,
07:02 instead of other insects?
07:04 Professor Qiu Zhongjun, who specializes in the study of microorganisms and parasites,
07:07 used cockroaches and flies, which also live in a bad environment, as examples.
07:11 Since the black water caterpillar can eliminate the pest,
07:13 it may have antibiotics that can keep them alive.
07:18 If you look at the insects, such as flies and cockroaches,
07:20 there must be a reason for them to survive in the dirtiest environment.
07:26 Do they have strong antibodies or proteins in their body?
07:33 We found that the black water caterpillar also has antibodies.
07:37 The main reason is that the insects eat bad food and live in a bad environment.
07:42 The insects are full of harmful viruses, bacteria and parasites.
07:47 We wanted to know what we could learn from the insects,
07:51 and whether we could use the proteins in their body to cure the diseases of humans.
07:58 The black water caterpillar can be used as medicine and even replace food.
08:03 Isn't that the same as the black water caterpillar that humans have eaten?
08:07 Both professors are of the same opinion.
08:10 As long as it is for humans, it must be food-safe.
08:15 If it is for humans, or if it is for human consumption,
08:20 it must have a clean source.
08:24 It must be fed clean food, such as vegetables and fruits,
08:28 instead of eating the feces of animals or fish.
08:33 It is still not hygienic.
08:35 We do not recommend using black water caterpillars that consume fish.
08:39 The black water caterpillars we developed are used to feed
08:44 toy frogs, coffee frogs and fruit flies.
08:48 We can make sure that they are clean and hygienic.
08:52 We can use them to make any food.
08:56 Yes, the black water caterpillars and insects that humans eat must meet food safety standards.
09:05 The black water caterpillars that help to clean up the waste is unlikely to become animal feed.
09:10 How should it be handled?
09:12 Professor Qiu Zhongjun, Professor of Medicine at Malay University of Technology, said
09:17 that the black water caterpillars have the substance of chitosan,
09:22 which can be used to clean up the waste.
09:26 This substance can help to clean up the waste.
09:32 It is also good for the environment.
09:34 The black water caterpillars can be used to grow crops,
09:38 and produce more economic and circular effects.
