Are you buying year old apples at the grocery store?
Most likely, that answer is yes. Apples at the grocery store may be many months old. A number of crops are stored in ways to extend their lives. Apples can be stored for months in temperature and humidity controlled environments as well as treated with a gaseous compound, 1-methylcyclopropene. If picked off the tree and not treated or stored properly, apples will only last a few weeks.
According to the Today article, That apple you just bought might be a year old – but does it matter?, this doesn’t mean you should panic. Experts state these treatments are perfectly safe. What you lose over time are taste and antioxidants.
Right now, most grocery stores do not disclose the age of the apples. If this is something that bothers you, your best bet is to buy locally and in season.
