Refreshening studies of breads with and without surfactants were conducted. Breads stored at 2 and 30 C were refreshened by heating at 90 C for 45 min. Those stored at 2 C for two days and refreshened regained the original firmness. Breads refreshened two and three times, however, did not revert to their original firmness. Refreshening of breads kept at 30 C resulted in only partial recovery of the firmness of fresh bread. Surfactants (sodium stearoyl lactylate and Atmul 500) were helpful in restoring original freshness. Breads kept at 2 C for two and four days could be restored to original firmness by first and second refreshenings; at 30 C, original firmness was only partially recovered. Firmness data are supported by organoleptic tests, X-ray diffraction patterns, and soluble starch data.
