Summary

Spanish translation of an article presented at the IIR meeting, held in Dresden, Germany, 1990 (see IIR Bulletin, ref. 92-1207). The effect of sinusoidal temperature fluctuation on quality loss in frozen ground beef containing 15% fat was studied. Four packaging methods were used. The samples were stored at 3 average temperatures, each of which had 3 amplitudes of fluctuations. The frequency of temperature fluctuation under controlled ambient temperature was 8 and 4 cycles/day. To study the effect of frequency, it was accelerated up to 12 cycles/day and the average temperature was -10 deg C. The samples were stored from 3 to 15 months. Results are given as far as weight loss, sensory changes, shelf life, microbiology, are concerned.
