🌟 Fermentation with Sugar and Yeast

In this educational video, Ryan and Teresa explore the process of fermentation using sugar and yeast. They explain that fermentation is a chemical breakdown by microorganisms, typically resulting in gas and heat production. The experiment involves using bottles, sugar, yeast, balloons, a funnel, and warm water. Safety gear like gloves, goggles, and lab coats are recommended. The process starts by adding yeast and varying amounts of sugar to different bottles, followed by warm water. The bottles are then covered with balloons to observe the gas production over an hour. The video demonstrates that the more sugar present, the more carbon dioxide is produced, causing the balloons to inflate. The hosts also discuss the role of yeast in bread rising, explaining that yeast consumes sugar and produces carbon dioxide and ethanol as waste, which helps the bread to rise. The video concludes with a call to action for viewers to support their content, subscribe for future episodes, and engage with them on social media.

Keywords

💡Fermentation

Fermentation is a biological process that involves the conversion of sugars into alcohol and other products by the action of microorganisms, such as yeast. In the context of the video, fermentation is demonstrated through the breakdown of sugar by yeast, resulting in the production of carbon dioxide gas and ethanol. This process is central to the experiment, as it visually manifests through the inflation of balloons, illustrating the gas production.

💡Yeast

Yeast is a type of fungus used extensively in baking and brewing due to its ability to ferment sugars. In the video, yeast is the microorganism responsible for the fermentation process. It consumes sugar, producing carbon dioxide and ethanol as byproducts. The video script mentions that yeast is very small, with 1 gram containing around 25 million cells, and it has been utilized for thousands of years to help bread rise.

💡Sugar

Sugar is a crucial ingredient in the fermentation process as it serves as the food source for yeast. In the video, different amounts of sugar are added to bottles to observe the effect on yeast activity. The script describes adding varying teaspoons of sugar to different bottles to demonstrate how the quantity of sugar affects the production of carbon dioxide.

💡Carbon Dioxide

Carbon dioxide is a gas produced as a byproduct when yeast metabolizes sugar during fermentation. In the video, the production of carbon dioxide is evidenced by the inflation of balloons placed over the bottles. The script explains that as yeast consumes more sugar, it produces more carbon dioxide, which increases the pressure inside the bottle and causes the balloon to expand.

💡Ethanol

Ethanol, also known as alcohol, is another byproduct of the fermentation process alongside carbon dioxide. It is produced when yeast breaks down sugar. The video script mentions ethanol as part of the waste products released by yeast when it metabolizes sugar, although the focus is more on the carbon dioxide and its effect on balloon inflation.

💡Bottles

Bottles serve as the containers for the fermentation experiment in the video. They hold the mixture of yeast, sugar, and water where the fermentation process takes place. The script describes using multiple bottles, which can be made of glass or plastic, to conduct the experiment and observe the effects of different sugar quantities on gas production.

💡Balloons

Balloons are used in the experiment to visually demonstrate the production of carbon dioxide gas. As the gas is produced by the yeast fermenting sugar, it fills the balloon, causing it to expand. The video script explains that balloons are placed over the bottle spouts and left to sit for an hour, with the expectation that they will grow in size as the gas accumulates.

💡Warm Water

Warm water is used in the experiment to activate the yeast and initiate the fermentation process. The video script instructs adding 1 cup of warm water to each bottle to mix with the yeast and sugar. The warmth of the water is important as it provides a suitable environment for the yeast to thrive and begin the fermentation process.

💡Gas Production

Gas production is a key outcome of the fermentation process demonstrated in the video. The script describes how the carbon dioxide gas, produced by the yeast as it breaks down sugar, causes the balloons to inflate. This visual evidence of gas production is central to understanding the fermentation process and its effects.

💡Safety Precautions

Safety precautions are recommended in the video to protect from spills and splashes during the experiment. The script mentions the use of gloves, goggles, and an apron or lab coat. These precautions are important to ensure that the experiment can be conducted safely, even though the substances used are not hazardous.

💡Chemical Breakdown

Chemical breakdown refers to the process where substances are decomposed into simpler components by chemical reactions, often catalyzed by microorganisms. In the video, fermentation is described as a type of chemical breakdown where yeast breaks down sugar, leading to the production of gases and heat. This concept is fundamental to understanding the science behind the experiment.

today on S side guys fermenting yeast

and

[Music]

[Music]

sugar welcome to S guys I'm Ryan and I'm

Teresa and today we're looking at

fermentation with sugar and yeast we'll

be producing gas and it won't be me this

time this is a viewer requested episode

thank you to this viewer for

recommending this episode fermentation

is a chemical breakdown of substances by

bacteria yeast or other microorganisms

usually involving the production of

gases and heat the equipment and

ingredients you're going to need for

this episode includes multiple bottles

they can be glass or

plastic sugar yeast balloons a funnel

measuring utensils and warm water we're

not working with anything hazardous in

this episode but we still recommend

gloves goggles and an apron or lab coat

to protect from spills and splashes the

first step in our experiment is to add

all your ingredients into the bottles

using a funnel add one package or 2 and

1/4 teaspoons of

yeast now we're going to add the sugar

in the first bottle we're not going to

add any sugar in the second bottle we're

going to add 1

teaspoon in the third bottle 2 teaspoons

and in the fourth bottle 3

teaspoons with all your dry ingredients

in the bottles add 1 1 cup of warm water

into each

bottle with all the ingredients in your

bottle cover your bottle with your thumb

or put the lid back on and give it a

gentle

mix with all the ingredients in the

bottle put one balloon on each bottle

spout and leave them somewhere warm to

sit for an

hour over the next hour or two the

balloons will gradually grow in

size after few hours you'll notice the

balloon that was covering the bottle

that had the most sugar in it grew to a

larger

size let's look at this experiment a

little closer yeast is a fungus and

there are about 160 known species of

yeast yeast is very small 1 G holds

around 25 million cells and has been

used for thousands of years to help

bread rise but how does a fungus help

bread rise it has to do with what yeast

eats how they metabolize that food and

what waste products are released yeast

feeds on sugars and starches when the

yeast consumes the sugar in our bottle

it breaks it down to be used as energy

but like all living beings waste

products are produced when metabolizing

food when the yeast metabolizes the

sugar the waste produced is carbon

dioxide gas and ethanol the carbon

dioxide gas floats out of the liquid

into the bottle producing Bubbles and

eventually floating up into the balloon

as the yeast consumes more sugar and

produces more carbon dioxide the

pressure inside the bottle and balloon

increases this pressure presses on the

walls of the balloon causing it to

expand and grow the equation for this

reaction looks like this the reactant

sugar sucrose is on the left and the

products ethanol and carbon dioxide are

on the right the bottles with greater

amounts of sugar have more food for the

yeast to consume which results in larger

amounts of carbon dioxide produced and a

larger balloon on the top of the bottle
