Rice Flour in Place of Wheat Flour
July 22/Journal of Technology & Science -- "The development and study of new gluten-free foods of high quality that are suitable for people with celiac disease is necessary, since there is increasing frequency of people who have been found to be allergic to proteins in wheat flour. Rice is one of the most used cereals in these special foods elaborations," report scientists writing in the journal Food Science and Technology International.
"However, replacement of wheat flour by rice flour usually leads to a noticeable decrease in the quality of the products discussed in this study. This work studied the individual and combined influence of xanthan gum (XAN), emulsifier, pregelatinizated starch and transglutaminase on quality of rice yellow layer cake (YLC) by means of a systematic study based on a two-level half-fractional factorial experimental design. Size and shape, texture, color, crumb grain profile and sensory acceptance were evaluated in YLC. XAN, white egg proteins, and emulsifier showed significant positive effects on volume, texture and crumb grain characteristics," wrote F. Ronda and colleagues, University of Valladolid.
The researchers concluded, "The feasibility of rice YLC reaching acceptable levels of customer satisfaction was demonstrated."
Ronda and colleagues published their study in Food Science and Technology International ("Improvement of Quality of Gluten-free Layer Cakes." Food Science and Technology International, 2009;15(2):193-202).
