Abstract:

In this paper we studied the effect of the baking method on the preservation of beta-carotene in two types of products: pan wheat bread and sponge cake. Five sources of beta-carotene were used in the study, three of which are commercially available samples, and the two others are experimental samples of supramolecular complexes of beta-carotene with alpha- and beta-cyclodextrins in powder form (molecular ratio 1: 1). Bread and sponge cake were baked by convective and electric resistance methods. The values of temperature and current flowing through the dough were monitored during electric resistance baking. The beta-carotene content was measured in the dough after kneading, in the cake batter after mixing and in the finished products after baking and cooling. The beta-carotene content was evaluated by spectrophotometry after extraction. The control samples of bread and sponge cake were baked without adding beta-carotene. Different sources of beta-carotene exhibited varying stability in bread and sponge cake. Bread samples baked by the electric resistance method with addition of supramolecular complexes had minimum losses of beta-carotene. Electric resistance baking ensured lower losses of beta-carotene in bread and sponge cake samples.
