The subject of undertaken researches was to determine influence of temperature of storage to the dynamism of staling process in frozen cake products. Yeast products of two producers X and Y were the research material. Ready yeast cakes were frozen with a chamber method and were stored for the period of 180 days in three storage chambers. In two chambers constant temperatures of -12ºC and -22ºC have been held, however in the third one there were conditions of variable temperature (-12ºC;-22ºC). Depending on thermal conditions, staling rate changes were researched with two methods: by determining the value of blue quantity and by defining the ability to absorb and hold water in a piece of cake. On the basis of achieved results it was stated that values of blue quantities and abilities to hold water during the storage have decreased, what resulted in a decrease of product’s quality, caused by staling of cake products. Changes in the structure of pulp caused by ageing of the yeast cake remained in a strict dependence with environment temperature conditions. The most beneficial storage version was the temperature of -22ºC. Additionally, used methods of staling rate measurement characterized with a high correlation coefficient, what means that they can be used in exchange.
