You don't have to store your perfect fruits/veggies in a treasure chest. You can separate them and store them within your, or another Sims inventory. The best fruit/veggie will be the one on top and the lowest the one on the bottom of the stack. There is a way to expand the list of a particular fruit/veggie, which I forget how to do. If you are within your own inventory I think it's a double click on it to pop the box open and show each fruit/veggie in the particular frame separately. Then, when you mouse over the fruit/veggie, it tells you what quality it is. Simply drag the perfect ones to a different slot between others. I once had mine all lined up like little soldiers from Perfect to normal quality. (I obviously was bored that day) It made it easier for me, although VERY time consuming, to see what quality they were and sell off the lower quality ones to make room for only the top three best.
