The crystallinity of bread stored at -18degrees, 4degrees and 25degreesC for up to 20 days was studied using X-Ray diffraction analysis. Relative crystallinity of bread was calculated from the total diffraction at specific angles. Firmness and crystallinity both increased during storage. When moisture migration from the crumb to the crust occurred during staling, the development of firmness was well described by a simple equation accounting for the changes in crystallinity, moisture and storage temperature.

Abstract
The crystallinity of bread stored at -18degrees, 4degrees and 25degreesC for up to 20 days was studied using X-Ray diffraction analysis. Relative crystallinity of bread was calculated from the total diffraction at specific angles. Firmness and crystallinity both increased during storage. When moisture migration from the crumb to the crust occurred during staling, the development of firmness was well described by a simple equation accounting for the changes in crystallinity, moisture and storage temperature.File in questo prodotto:
