Using fruit to preserve breadFeatured science projectScience project video


The hypothesis that  bread baked with fruit paste  will not spoil as quickly as plain bread, is proven to be true.

The use of synthetic preservatives and food additives to various types of foods, fruits and vegetables to make them last longer is a controversial topic that is often debated. Consumption of  synthetic preservatives has been shown to cause several health problems including respiratory difficulties. Even though natural preservatives may be  costlier, their use should be encouraged to avoid the side effects caused by synthetic preservatives.

The experiment can also be done by adding cinnamon powder or pounded garlic to the bread.

Try to repeat the experiment under different room temperatures.
