Throwing away food is preferable to getting food poisoning, but the amount of wasted food is very high- and food supply appears to be getting more critical. So testing for food spoilage organisms, allergens, and chemical problems like heavy metals should be considered very important. Several papers in this issue show the kind of initiative that preserves the food supply, and keeps people eating healthy. This paper reminds one of the "man that wasn't there, and wasn't there again today." When food manufacturers test all ingredients for traces of peanut, they may come a cropper when using ELISA tests for peanut allergens on caramel color. Seems the tests are confused by a matrix interference triggered by some caramel color products, but in final food products, the tests don't show false positives. The paper titled "False Positive Detection of Peanut Residue in Liquid Caramel Coloring Using Commercial ELISA Kits" outlines the Univ. of Nebraska's search for a way to test ingredients without throwing them all away.
