Hello!

This is Domeki (Domeki) in Libanes.

Today, I visited Osaka Prefectural Izumi High School!

Izumi High School is nearest to Kishiwada Station.

Speaking of Kishiwada,decorative portable shrineYes!

I was born in Tohoku and grew up in Tohoku-Hokkaido, so the first time I spoke directly with a Kansai person was in college.

I was "kind of impressed" by the Kansai dialect of the girl, who seemed to be from this city.

While you are thinking about these things, you will arrive at the school.

Consideration of Yogurt Fermentation ( Science Club, Osaka Prefectural Izumi High School )

We have conducted several experiments on yogurt production by lactic acid bacteria fermentation and obtained the following findings that open up new possibilities for yogurt. It was found that yogurt can be made from soy milk and skim milk as well as cow's milk by fermentation with lactobacilli. It was found that a wide range of lactobacilli can be used to make yogurt, including lactobacilli obtained from intestinal preparations and bedded foods. In order to evaluate the progress of lactobacillus fermentation, a simple method to measure the gel consistency was devised. The results suggest that the fat content of milk and the fibrous component of soy milk are involved in the firmness of yogurt. The results suggest that lactic acid bacteria play a role in suppressing spoilage.

Actually, I am also culturing yogurt.

It's true that different types of milk seem to curdle differently.

So we had a rehearsal for the oral presentation.

Hear the announcement,

The school has been making a variety of unique presentations, and this study was also started in April.

It was very interesting to examine various conditions and try to quantify and compare the gelatinization of yogurt.

We will also continue to conduct research to scientifically clarify the issue,

I think it is wonderful that they are creating their own equipment (left and middle photos).

The panda on the right in the photo is called Panda-chan from the Science Department.

What are your thoughts on the presentation?

It was very good to see the enthusiasm with which they focused on a familiar product, yogurt, and their research.

I felt it was a bit of a waste of time,

(1) Experiments to study conditions to establish research methods

Consideration of the amount of milk to be used in the experiment, fermentation time, etc.

(2) Research

The results of the research theme, such as differences in fermentation by type of lactic acid bacteria

The point is that the two were mixed up and spoken in parallel.

When we asked him about his research, he said that it sounded interesting at first and that he did a lot of research in accordance with his interest.

As is often the case with research, if you go through the research pattern of trying to find out more about things anyway,

We tend to talk about the results in the same order.

It tends to be a somewhat divergent presentation, so be sure to organize the results properly and create a story.

We also recommended making a graph of the results, since they were all represented in a table.

For example, this is a table,

The following are the results of a certain treatment on samples A-D and observation of their subsequent condition.

Even with all this, it is difficult to intuitively determine which samples increase or decrease in trend.

However, when this is graphed,

It can be seen that the seemingly large number B is actually not related to either an increase or a decrease.

It is also intuitive that the largest trend of increase is A.

Please try to use tables and graphs differently!

It seems that about 200 people will be there on the day of the event, but please do your best and don't be nervous!

That is all!　(HYAKUMEGI)

Summary of points

(ix) Select and create a graph or table to represent what you want to say most as a result.
