You should know that we are not here to do your homework. What kind of help do you need, since it is not so difficult to squeeze juice out of fruits. What fruits do you expect to have a low water content? Hint: also include tropical fruits.

Is it the yield of fruit juice that you are interested in or is it water content of the fruit...or is it both? There would be different approaches for each endpoint, not necessarily exclusive ones though. Give us some more details and any thoughts you have had about which fruits to use.

the homework is actually about the amount of fruit juice yield using proctase as a catalyst (so to speak) what i have chosen to do is to compare several types of fruit by seeing their fruit juice yield after 30 minutes of exposure to proctase but i was wondering whether the amount of water the fruit contains will have any effect on the amount of yeild the actual question now better worded is will the amount of water in a piece of fruit, keeping the mass the same for each piece, affect the outcome of results?
if so i will have to scrap this experiment and move on to some other.
thanx very much for your replys

Monique, what fruit would have a low water content to begin with? I can't think of any because all the fruits I can think of are very juicy, including some that are of the tropical variety. If they are juicy I would assume it means they have a moderate to high water concentration.

How about raisins? :wink:

Seriously, in general fruits do contain a lot of water, but a comparison across fruits might yield considerable variation. How about a banana, or better yet a plantain, compared to a melon? or a durian compared to an orange? I don't have the numbers in front of me, but I would think on a weight basis the melon and orange would have more water.

How about avocado :biggrin: hard to squeeze juice out of that :wink:

I thought avacados were vegetables. :bugeye: Don't raisins count as grapes because they are the dried up form?

No, they are a fruit :tongue:

According to dictionary.com -- A tropical American tree (Persea americana) having oval or pear-shaped fruit with leathery skin, yellowish-green flesh, and a large seed.
The edible fruit of this tree. Also called alligator pear, avocado pear.
