Optional: Leave the apples slices on the plates overnight. Then repeat the rating for each of the apple slices the next day. Many fruits and vegetables undergo browning when they are cut and the tissue is exposed to the air. This is due to the activity of the enzyme polyphenol oxidase (PPO, EC 1.14.18.1) with endogenous substrates. In this laboratory experiment, students prepare slices of different varieties of apples and assess the rate of browning.Mar 17, 2022 · We used four small apples, in four small bowls with four different coatings. water baking soda vinegar lemon juice It worked out really well, nice and even, both Austin and Brookland were able to cover two apples each, no fighting involved.

On the first day Vitamin C had no browning on the apple and was the best vitamin for the experiment. Vitamin A, D, and E had less browning than the regular apple, but not as much as Vitamin C. Each vitamin got worse on the second day.the same day for each experiment. Size of apples: it is too hard to cut and weigh the apples because of how quick the browning starts. So I tried to cut the apple in equal slices of 8 pieces each. I check the 1kg bag of apples I bought each had 9 apples each so that the apples were pretty much the same size. Fair test:This is because there is a compound within the apple called catechol which, when exposed to the air, becomes oxidized by the oxygen in the air and produces benzoquinone, which makes the apple appear brown (Andrew Clapper's Online Journal, 2007). This chemical reaction is catalyzed by the enzyme catechol oxidase (Figure A.1).So it supports my hypothesis that low ph level will inhibit enzyme browining.
