Beyond normal shelf spoilage from super markets there's a lot of ingredients that can only really be bought fresh in amounts much larger than can really be used. For example cilantro or parsley generally comes in either in cheap large bunches or much more expensive individually (plastic) packaged smaller servings but the large bunches is way more than most people could reasonably use before it begins to wilt and rot so it's wasted.

Put the cilantro/parsley stems immersed in a glass of water. Cover the leaves with a plastic bag and it will keep in the refrigerator for at least a week without wilting

Might try that. Space is a little tight in our fridge though so it might not work.
