Preserving Bread with Fruit | Science Fair Projects | STEM Projects
Ever wanted to know how to make bread last longer? In this project, you'll find out how adding fruit paste to bread can help preserve it!

Hypothesis

The hypothesis is that bread with fruit paste added lasts longer compared to plain bread.

Method & Materials

You will buy a loaf of plain bread, a loaf of raisin paste-filled bread, a loaf of prune paste-filled bread, and a loaf of dates paste-filled bread from a local bakery. You will then leave the bread in a cupboard and inspect it everyday with a magnifying glass for signs of bacteria or mold growth.
You will need a loaf of plain bread, a loaf of raisin paste-filled bread, a loaf of prune paste-filled bread, a loaf of dates paste-filled bread, a magnifying glass, a pair of plastic gloves, a bottle of disinfected water, a soap, and a clean towel.

Results

It was observed that adding the paste made from raisins, prunes and dates into the bread, helped to increase the shelf life of the bread by 2 to 3 days.

Why do this project?

This science project is interesting because it explores a natural way to preserve food, which is something that has been done for centuries. It also shows how adding natural preservatives like fruits can help to reduce the pH level and increase the shelf life of bread.

Also Consider

Consider repeating the experiment under different room temperatures. Also, try adding cinnamon powder or pounded garlic to the bread.
