AISubs v3.5
Here we are, Hiroshima Industrial University
Are we going to do it at the university today?
Yes, we are going to do it for the first time for students at the university
Don't you want to know what kind of goals the people of the same generation as us have for their university life and what we are learning?
Yes, we do
Hiroshima Industrial University has four departments of Engineering Department, Information Department, Environmental Department and Life Department.
The university focuses on science and technology, and trains future technicians.
Students from many prefectures, including Chinese countries, are entering the university.
Soraha is a senior in high school now.
Do you have any aspirations for the university?
I wrote that the food is delicious.
I've heard that the food at the university is delicious.
So, I'd like to compete for yakisoba bread or something like that.
I've never done it before, so I'd like to try it.
I'd like to compete for yakisoba bread at the university.
I'd like to do it.
You've changed.
Let's learn a lot about what we're doing today.
Yes.
First of all, let's eat something delicious.
This is the first college location of the program.
The university of science and technology is on a parade of unique research.
Researchers researching food discover surprising foods.
Here you are.
Wow!
What is it? What is it? What is it?
I'm scared. I'm scared. I'm scared.
In addition, research was carried out to solve the environmental problem Setouchi is facing now.
I'm scared. I'm scared. I'm scared.
From now on, it's college location for four weeks!
Two Steps!
Wow !
First of all, I'm going to Faculty of Life Sciences, Food Life Sciences
Wow !
Two steps of life !
That's right !
It's mysterious !
As the name "life" comes up, it means something like "animal" or "from the beginning"
I think so, too !
It smells good !
Hello !
It smells good !
You are eating something !
Let's ask the professor !
What are you studying now ?
I'm studying freeze-drying
Wow !
This is a risotto !
Until a while ago, it was dry or freeze-dried, isn't it ?
That's right !
I think it was dried up
I can't see it at all !
Why is freeze-dried food being studied ?
Freeze-dried food can't be heated up, so the flavor remains as it is
Moreover, it can be stored for a long period of time
For example, it can be a preservative food, and since the flavor remains as it is, it can be a protective food
I'm studying it in order to spread it out like that
Do you know how freeze-dried food is made ?
What ? I don't know !
It was square, wasn't it ?
Since it was square, it was like this
I know it !
This time it was risotto, but it was square in any food
What do you think of it ?
Everyone, it's in front of you
What ?
This is a machine for freeze-drying
It looks like an oven toaster
In this machine, a sample is put in and closed like this
Then, it is pulled in a vacuum
It is vacuumed
By vacuuming, dry water is evaporated and evaporation occurs
In the case of freeze-dried food, frozen food is put in this machine in advance
By vacuuming in advance, evaporation occurs
Evaporation means that ice becomes water vapor
Therefore, the temperature does not rise and the flavor is good
That's what this machine is about
Can any food be freeze-dried if it is put in this machine ?
Yes, it can be
Wow !
I want to try it !
Today, students of Food Life Sciences Department of Life Sciences processed various foods in freeze-dry
After this, freeze-dry foods at stores will appear
Here you are
Wow!
What is the freeze-dry food that students have tried?
Here you are
Wow!
Cake?
I want to eat it
Is it freeze-dry?
Yes, it is
It looks like it
I don't know
This is green tea
Green tea and strawberry
The other side is cake
Wow!
I want to eat it all
Do you eat it without boiling water?
Yes, we do
Please try it
Thank you for the food
Where do you eat it?
Thank you for the strawberry
I did it
What is it?
Is it the same feeling?
It smells
What is it?
It looks like baked sweets
Yes, it does
It's quite hard
Yes, it is
Since the cake is soft,
I was worried about breaking it, but it's firm
Do you eat it?
Thank you for the food
It's delicious. It's like a cookie. It's crispy.
The deliciousness of the cake is packed tightly.
Besides, the taste of matcha is full.
And now, chocolate.
But, it was sweet and sour.
But, when you put it in your mouth,
you can feel your moisture and softness of shortcake.
It's creamy.
The cream in between was delicious.
It was delicious.
It's a short story.
A cake is a cake with a short shelf life.
Yes, it is.
You can eat it in one day.
If you freeze-dry it, it will last for a long time.
It will last for a long time.
Yes, it will.
It will last for about half a year or a year, depending on how you freeze-dry it.
Then, you can buy a big cake and eat it little by little.
That's right.
It's profitable.
On your birthday, you may not be able to eat it all.
In that case, you can come here and say "Excuse me, professor."
It may be difficult to say "whole cake" in this situation.
You can divide it like this and bring it to me.
Yes, it's not over yet.
Next is Ms. Yoshiaki.
Yes.
What will come out this time?
Please.
Here you are.
Here is the quiz.
Ta-dah!
Ms. Takino and Ms. Sorano, what did you freeze- dry?
Yes.
Wait a minute.
Only the correct person can eat it.
What?
It's not good.
Soraho-chan is...
Wait a minute.
No, it's definitely not right.
It's probably right by its appearance and feeling.
Soraho-chan.
Yes.
Vanilla ice cream.
That's right.
I'm sorry.
I thought it was vanilla ice cream, but you said it's not, so I thought I'd give you a variety of different ideas and try to guess.
Then, both of you are correct.
The delicacy of vanilla ice cream is ice cream.
You can freeze ice cream, too.
What do you mean?
Because it's still frozen.
As it freezes, only water evaporates, so the shape remains.
That's why you can make ice cream.
Normally, you can't make ice cream here, can you?
It melts and breaks, doesn't it?
That's right.
Because it's still frozen.
That's right.
Thank you for the meal.
It's a cute size.
What is it?
I'm surprised.
What do you mean?
It melts in my mouth.
But it tastes like vanilla ice cream.
When I touch it, it feels a little soft.
Is that so?
As soon as I put it in my mouth, it melts.
Because it's freeze-dried ice cream, it doesn't melt even if it's hot like normal ice cream.
You can take it to mountain climbing or camping.
That's great.
In addition, this freeze-dry technology is useful not only for buildings, right?
That's right.
I'll get ready for a while, so I'll go to another department.
Thank you for your time.
See you later.
Thank you for your time.
The next department we're going to is the Environmental Marine Science Department.
It's difficult.
What does it mean?
Marine science...
I haven't said it yet.
It's like soil.
It's like natural soil.
Then, let's go.
Let's go.
Hello.
Are you doing something now?
What is it?
It seems like you are researching something in the aquarium.
Do you know what kind of research it is?
What kind of research is it?
Coral.
That's wrong.
That's close.
Look carefully.
Shijimi.
I'm sorry.
It's delicious.
Asari.
That's correct.
It's Asari.
Shijimi and Asari are similar.
I don't know the difference.
It's true.
Is that all?
That's right.
This is Asari we are raising.
That's amazing.
We are raising Asari on land.
It's rare to do it on land far away from the sea.
I've heard of doing it by sea, but it's quite far away.
Asari numbers are declining in Seto Inland Sea.
It's getting warmer and higher in recent years.
A big typhoon may come along with it.
It may rain heavily.
Asari will continue to live in this environment.
It's getting worse little by little.
I see.
Especially, we are raising Asari which is about 5 mm small.
Asari which is about 5 mm small cannot overcome harsh environments in summer.
So, we bring Asari which is about 5 mm small from the sea here.
We raise Asari until Asari becomes big enough.
When Asari becomes big enough, we put Asari back in the sea.
You put Asari back in the sea.
Asari which became big because of doing so is strong.
So, Asari will overcome harsh environments in summer.
Suddenly, I have a question for you two.
Asari does a very important job in Seto Inland Sea.
What kind of activities does Asari do?
I've heard of it.
Really?
Yes, Yumirin.
A mouth-watering hat.
What do you mean?
In Seto Inland Sea?
Asari's miso soup or something like that.
I have a question for you two.
Asari does a very important job in Seto Inland Sea.
What kind of activities does Asari do?
I've heard of it.
Looks like it.
How does this water look like now?
Beautiful.
Yes.
Go ahead, Yumirin.
It makes the sea beautiful.
Yes, watermelons make the sea beautiful.
Asari's breed is plant plankton in the sea.
What Asari is breeding now is plant plankton.
Really?
There are many of them in the sea.
As you can see, it looks muddy now.
But, even if you put Asari's food here, it looks beautiful, doesn't it?
Asari takes all of Asari's food in his body.
The water he spits out is very clean water.
In other words, Asari is filtering the water.
Asari ate plant plankton and showed us how to filter seawater.
Now, I'm going to put a lot of Asari in this beaker with a lot of plankton.
It feels a little cloudy when there is a lot of plankton.
If you put it in like this, it will be almost transparent in about 30 minutes.
It's a little difficult to wait for 30 minutes, so I'll show you a video I took yesterday.
Oh, you're kind. Thank you.
It's like a cooking show.
I'm doing it 100 times faster.
I can do it in 18 seconds.
Let's get started.
Asari is moving.
Asari is putting out a water pipe over there, isn't he?
Asari is putting out a water pipe and filtering the water.
It's becoming transparent.
In addition, SDGs are doing research using this device.
Here's the question again.
What is this device for?
Electricity is generated.
How?
Rubbing the central part with your hands.
Electricity.
You said you make electricity, didn't you?
Yes.
What do you use it for and how is it made?
Water flow.
Correct!
That's right! The correct answer is to use a butterfly to generate electricity!
There is an generator inside of this vessel here.
And by adding the power of water mentioned earlier, the wings around it start spinning.
And by that spinning, electricity is generated.
Wow!
As for where electricity is generated, it is at the bottom of these bridges.
It is quite popular. There is a part of water flow.
And by installing it there, it spins.
Wow! That's amazing!
In the future, using the electricity generated by this technology,
we will be able to cultivate clams.
By using renewable energy, we will be able to cultivate more clean clams.
Since I didn't know about it before, I was able to gain new insights and knowledge.
I feel like I learned something new today.
Can you tell us why you chose the Department of Environmental Engineering?
I think there are many natural disasters in Japan.
I am interested in learning about how we can coexist with nature.
That's why I chose this department.
When it comes to environmental management,
it may be overwhelming,
but in this department, there is a connection between land and environment.
I think I came here while being conscious of that in terms of environmental management.
After all, people coexist with nature.
Thanks to you, I was able to know that we can live a comfortable life.
I'm glad.
Please continue to do your best for the earth and the Seto Inland Sea.
Thank you very much.
After visiting the Department of Environment, Land and Fisheries,
they got a call that the freeze-dried food was ready,
and went back to the Department of Food and Life Sciences again.
I heard that there is freeze-dried food that is not food, and I came back.
Is everything ready?
Yes, it is.
This is it.
Something black in front of you is frozen.
It's a little big.
Here is the last question of the day.
We process something using freeze-dried technology.
What is that "something" ?
Freeze-dried technology...
It contains water, doesn't it?
It contains water and is placed.
Yes, yes.
It's like a small ball of about 1 mm...
No, it's not.
Freeze-dried technology
I'd be happy if I got it.
What would you like to get?
Money.
I think I often get it.
When do you get it?
I don't really get it.
Thank you for your hard work.
Oh, yes, yes, yes.
Flowers.
You got it right!
Flowers? Flowers?
The correct answer is...
Seika!
Can I pick up a pen and look at it?
Yes, you can.
Can I?
It's beautiful.
It's a little different from a dry flower.
The color is still there.
That's right.
This is a dry flower.
If you fold it up and turn it upside down and dry it in the room, it will be this color.
The color is completely different.
Recently, it's called "preserved flower".
Preserved flowers are colored once with alcohol.
You can suck in your favorite color and make your own color.
I didn't know that!
This freeze-dried flower stays completely natural and doesn't color anything.
I didn't know you could make not only food, but also flowers.
Why did you study food biology?
I learned that only China can study freeze-dried food.
From there, I became interested in freeze-dried technology and decided to study it.
I like eating and I was interested in food.
I was interested in not only food nutrition, but also machines for manufacturing.
So I applied to this university.
I'm interested in agriculture.
Here you can learn not only food technology, but also plants.
I wanted to learn about plants and make people happy through food.
That's why I applied to this university.
You must have been happy.
I was surprised at the ice cream.
I hope we can easily get it in the future.
I'm rooting for you.
Thank you very much.
Hiroshima Industry University has cooperated with us in this shooting location.
Under the supervision of Mr. Akino Miyajima,
we aim to train technicians who can contribute to the area through learning from the Department of Engineering, Information Science, Environmental Science, Life Sciences, Department of Music, and Department of Chemistry.
Enjoy college life!
