Investigating the Effects of Salt Water and Lemon Juice on Apple Dehydration Rates

This study explores how salt water and lemon juice influence the dehydration rates of different apple types. Using a controlled experiment, red, green, and golden apple slices were dipped in salt water and lemon juice. Measurements were taken before and after soaking to analyze the impact of each solution. The results indicated that salt water significantly reduced dehydration rates compared to lemon juice, with the highest average weight retention observed with salt treatment. This research helps understand how solutions affect fruit preservation.

  2. QUESTION Does salt water or lemon juice have any effect on the rate of dehydration of different types of apples.

  3. prediction I predict salt water will have the effect on the rate of dehydration because the water content of apple are retained with the presence of salty water.

  4. Material • Salt water • Lemon juice • 6cups • A knife • 1red apple,1green apple, and 1golden apple • Some water • A weigher • A clock/time

  5. variables independent: the shape of the apple. Dependent: the dehydration of the apple. Controlled: the cups, the knife and the weigher.

  6. Procedure • Gather all materials. • Cut the red, green and golden apples 4 equal slices. • Weight the red green, and golden apple slices ,separately. • Pour water into a cup, then add ½ a cup of salt. • Split the different apple slices in half, dip 1 half into the salt water and the other into the lemon. • Let it rest for 5 minutes. • Then weigh again and write down the data. • Repeat steps 5,6 and 7 2x7 but don’t repeat the part split the different apple slices in half.

  11. Result I did 3 trials for each type of 1 apple ,1 with salt ,water and 1 with lemon juice. The data shows that the salt water had the greater effect on the rate of dehydration. The highest average weight of an apple using salt water was 0.5167, while using lemon juice was 0.473.
