A non-destructive spoilage detection method of detecting spoilage of a nutritional product having a water activity of at least 0.9 has the steps of: subjecting a nutritional product in a non-metallic sealed container to nuclear magnetic resonance spectroscopy followed by recording the peak free induction decay value associated with an initial nuclear magnetic resonance spectroscopy of the nutritional product. Subsequently the nutritional product is subjected to nuclear magnetic resonance spectroscopy and at least one other peak free induction decay value associated with the nuclear magnetic resonance spectroscopy of the nutritional product is recorded. Over time, at least two of the peak free induction decay values are compared from which a determination is made whether spoilage of the nutritional product is indicated. Preferably subjection of the nutritional product to nuclear magnetic resonance spectroscopy occurs on a regular basis and at approximately the same temperature of the nutritional. Ideally, the nutritional product has been packaged using aseptic processing.
