This is a our third experiment and first in our blog about DRYING OF FOODS. Using the our experiment's book, each group has been given tasks to dry fruits using the same formula but in different procedures. This is our last experiment in class using the guideline book. Then we will continue with our own idea experiment.

Objectives of the experiment

1. Identify the reasons for the procedures used in drying fruits and vegetables.

2. Compare the cost and the quality of home-dried with commercially dried fruits.

3. Evaluate the use of ascorbic acid in retaining color in dried products.

4. Compare the quality of products dried under the conditions tested in the experiment.

THE BASIC FORMULA OF FRUIT LEATHER

Ingredients

2 ½ c strawberries, hulled and cut cubes

25g Sugar
