Celem pracy było określenie stabilności właściwości mechanicznych ciastek biszkoptowych w czasie przechowywania. Wykazano zmiany odporności ciastek biszkoptowych na działanie siły ściskającej w zależności od wilgotności względnej środowiska i czasu przechowywania. Stwierdzono znaczące zmiany właściwości mechanicznych ciastek przy niewielkich zmianach ich aktywności wody.

The aim of this work was determination of mechanical properties of sponge-cakes during storage. It was found that environmental water activity as well as storage time have significant influence on resistance to compressive force. It was showed that essential changes of sponge-cake mechanical properties appeared parallely with small changes of their water activity.
