Our body needs important nutrients to support its

healthy condition, that is why it is imperative that our

food consumption should include healthy foods that

contain good amount of nutrients sufficient enough to

supply our body with its required daily nutrition. This

project deals with finding out various pH values of juices of different vegetables and fruits.

Apple juice ranges in pH fro, -.- to /0 as different t1pes

of apples have different pH levels.

The pH of grape juice ranges. fro, about 2.42 to -.-0

depending on the t1pe of grape used.

the t1pe of orange used.

between 2.- and 2.2.

RES=T>!fter performing the p" tests on different vegetables and fruits, it is

observed that most fruits and vegetables contain %uices which are acidic in

nature.

The investigated fruits and vegetables are all found to be acidic, among

which, fruits are more acidic than the vegetables.
