The purpose of this lab was to determine the amount of glucose in certain substances through a simple taste test.
The materials for this experiment were:
The materials for this experiment were:
- Sucrose
- Glucose
- Fructose
- Galactose
- Maltose
- Lactose
- Starch
- Cellulose
- Plastic cups
- Fake spoons
For the procedure, we first dumped the contents onto labeled pieces of tissue paper. We then tasted each of the substances using a plastic spoon and rated it on its sweetness. The table is below.
We were also tasked with finding out what the models of each substances molecules represented. the images are below.
Observing the data, we observed that glucose and fructose were the sweetest and most diabetic. They were both monosacchrides, so the amount of rings does affect the taste and texture, the more rings a substance has it is more powdery and fine, while the substances where there were less rings, they were more grainy and chunky. Some factors that could have affected our observations were different taste buds, using the same finger, and human error in general.
Overall the lab went fairly well. We recorded the data fairly well and our taste tests were accurate. We could have kept our hands off the fructose and glucose, but it happens. This lap was fairly enjoyable.
