It's likely Food Chemistry by Owen Fennema.
Yes it is very comprehensive and good. Basic Food Science texts will have some sections on Food Chemistry but will also include sections on Food Engineering, Food Processing, Food Microbiology, Sensory Evaluation, etc. This focuses just on Food Chemistry (Chemistry of Water/Ice, Protein, Carbohydrates, Fats, Minerals, Vitamins, Flavours, Colours, Additives, etc.), then some special chapters on Milk Ingredients, Meat Proteins, Rheology, etc.
