Effect of freezing on the physical and chemical characteristics of cheese bread

Abstract

The quality of cheese bread is directly linked to the raw material used, the preparation of the dough, freezing, and baking. Fail in these processes may result in a product of low acceptance in the national and international market. The present research was carried out at the Food Science Department of the Universidade Federal de Lavras, Minas Gerais with the aim to accompany the physical and chemical characteristics of the dough and cheese bread, during a period of 120 days of freezing. The modeled dough of cheese bread presented lower moisture content value in the fresh dough; the ash content, ethereal extract and pH decreased with freezing however, the acidity increased during this period. In relation to the cheese bread it was verified that the moisture content and ash values did not present variation during the period; the pH presented variations during the freezing, with smaller values at the end of 120 days; the lipid content decreased with the freezing, and the acidity decreased until approximately the 60th day, with subsequent increase until the end of the freezing. The frozen storage also led to an increase in the compression force, that is, a larger firmness of the cheese breads.
