protein, carbohydrate, and bioactive components. These by- products are suitable
for food application, as no chemical treatment, such as solvent application, is ap-
plied during cold- press processing. The most important problem in the production
of low- fat salad dressing is the less compact structure resulting from the reduction
of fat. Protein- and carbohydrate- rich ingredients are used for the development of
this structure. In addition, salad dressings are poor food groups in terms of bioactive
components, and their bioactive properties should be improved. In this study, the
comprehensive physicochemical and bioactive characterization, and potential use of
these by- products in low- fat salad dressing as fat replacers were firstly investigated.
