[Formulation, preparation and evaluation of shortening, laminated and cut biscuits, for diabetic patients]. / Formulación, elaboración y evaluación de galletas de masa corta, laminadas y cortadas, para diabéticos.

Laminated and cut cookies formulated with natural and/or artificial sweeteners as substitutes of sucrose, are presented as a new alternative of choice for persons on a restricted diet. According to data in the literature, market availability and technological and economic limitations involved in the use of pure sweeteners, four mixtures were selected for the formulation of the cookies, instead of sucrose. Their composition and relative sweetness were as follows: (table; see text) After the statistical analysis of results, formulations presenting significantly superior quality characteristics were selected. As observed, all alternatives subjected to evaluation were grade 1. A study of acceptability by diabetic patients was carried out with these products through a ranking test, in order to determine which were the formulations preferred. This revealed a significant preference for the cookies containing saccharin-sorbitol = 0.35:99.65, at a 1% level of significance. Their nutritional and caloric values, as well as the chemical composition of the selected formulations were then determined. The results showed a 10.9% decrease in caloric contribution.
