| Abstract: | Application of Antioxidants for Improving the Storage Properties of Shortenings I: Study of Primary Non-Volatile Products of Autoxidation In shortenings stored at 28°C and at 2°–4°C in the presence of various antioxidants (ascorbyl palmitate, butyl hydroxyanisole and propyl gallate) the content of non-volatile autoxidation products, the primary products as well as those formed in the later stages, was determined. The organoleptic properties were determined at the same time. The samples containing ascorbyl palmitate showed the least content of autoxidation products and the best organoleptic properties. For the determination of the products of autoxidation from shortenings the direct UV-spectrophotometric method was as useful as the determination of peroxide number. |
