From "Top 100 Baby Purees"... "Aviod dried apricots treated with sulfer dioxide, as these can trigger asthma or allergies in susceptible babies. Sulfer dioxide is used to keep the bright orange color, so it's best to choose darker brown dried apricots".
Read the ingrediants carefully. You can also attempt to make your own. You can use your oven. I have never tried it, but I do have directions.
