Shelf life Testing: Procedures and Prediction Methods for Frozen Foods Bin Fu Kellogg's Battle Creek MI. Theodore P. Labuza Dept. of food Science & Nutrition, University of Minnesota 1334 Eckles Ave., St. Paul, MN 55108. 2. 1 9 . 1 Introduction The Shelf life of a food can be defined as the time period within which the food is safe to consume and/or has an acceptable quality to consumers. Just like any other food , Frozen foods deteriorate during storage by different modes or mechanisms, as summarized in Table 1. Microbes usually are not a problem since they cannot grow at freezing temperatures unless subjected to extensive temperature abuse above the freezing point. Enzymes are a big concern for Frozen foods, which can cause flavor change (lipoxygenase) in non-blanched fruits and vegetables and accelerated deterioration reactions in meat and poultry (enzymes released from disrupted membranes during precooking).
