Abstract
A review. With vegetables, losses of soluble constituents are generally least in frying, greater in steaming and greatest in boiling; a large vol. of cooking water, slow cooking, high pH and holding after cooking all favor losses of thiamine and vit. C. With meat and fish, losses of soluble constituents arise chiefly from shrinkage of the fibers; protein losses may be as high as 20%; net losses of fat and B vits. are not serious if the drippings (or stock) are consumed. In baking bread, the avg. loss of thiamine is about 20%.
