I prefer not to buy fruit & vegies at a supermarket.
In general, they are selling most fruit in a semi-ripe state, but once it's removed from the tree it never "ripens" - and often, it doesn't even get any softer. Chewing peaches and nectarines and pears is like biting into a granny smith apple, which is nonsense.
The bananas go from green (in store) to brown, in a few days. They don't keep well after you buy them.
Woolworths sells various salad vegetables in sealed packs, but I have been told they do this so they can seal them in with an inert gas, and once you pierce the film on the box they're in, they wilt in no time.
Berries are often sold with a low price - which is almost always an indicator that they are about to hit their "use by" date. Use by dates aren't displayed on these items, so they get away with it.
A lot of their stuff is imported, so it's been a while since it saw a farm - then sent all over Aus., to regional distribution centres, to be stored again in vast cool rooms. BIG cool rooms don't function properly - ask any refrigeration specialist. Then trucked to the back of all the regional supermarkets, left out of sight till it's time to display them. The whole process is a recipe for stale produce. Even their grocery & dairy lines are hitting the shelves with "use by" dates that are far too close, already. I am rapidly losing confidence in their ability to stock their supermarkets with "fresh" anything at all, not just fruit & vegies.
