Vegetable oils are generally excellent sources of polyunsaturated
fatty acids. Although general consumption of
fats and oils has increased, recent trends in the baking industry are to reduce total usage of fats and oils and to
replace plastic fats with liquid vegetable oils (Chung and
Pomeranz 1983, Kamran et al. 2005). Two of the changes
recommended in a recent study by Salz (1982) were
replacement of most high fat baked products by those
lower in fat and replacement of some animal fat by
polyunsaturated vegetable oil products.
