The purpose of the study was to analyse the effect of changes in the composition of raw material and agglomeration on sorption properties of a multi-component food, in the example of a powdered cocoa beverage. The basic composition of the mixtures was 20% of cocoa and 80% of sucrose. A change in raw material composition involved partial or total replacement of sucrose with a mixture of glucose and fructose, or with maltodextrin. Analysis of sorption properties demonstrated variability in the course of isotherms of water vapour sorption for components of the powdered cocoa beverage. Limiting water activity (aw) was determined for the value of 0.529. The conducted analysis detected no significant effect of agglomeration on water content in the tested products. However, a significant change in the raw material composition was demonstrated.

Stefan Grabiński, a famous Polish author of weird fiction, who is known especially for his collection of short stories Demon ruchu (The Motion Demon, 1919), lived and worked in a period marked by a new artistic style – expressionism. Although Grabiński came from Lviv, often regarded as a province in Poland after the Great War, he could have a contact with the latest ideas concerning art and philosophy. Indeed, both in his short stories and in his novels may be found some traits typical for the expressionist poetics as, for example, a subjective perspective, a color sensitivity or a tendency to violent and dynamic use of formal elements. Grabiński was fascinated by a German literature – he read Gustav Meyrink, E.T.A. Hoffmann and an expressionist magazine “Der Orchideengarten”. Moreover, he liked going to the cinema where he could watch, for example, a famous German expressionist film – The Cabinet of Dr. Caligari. The only text by Grabiński which was adapted into film in his life was a short story Kochanka Szamoty (Szamota’s Mistress, 1922). Although this seemed to be a great material for an expressionist film, the director – Leon Trystan – decided to realize it in an impressionist poetics.

The article treats about a forgotten play Zaduszki (All Souls’ Day) by Stefan Grabiński, widely known as the author of fantastic literature and horror stories. The play Zaduszki consists of three parts: 1. Strzygoń. Klechda zaduszna; 2. W dzień zaduszny; 3. Sen Krysty. Misterium zaduszne. First of them is written in folk dialect. The second one, sometimes named „the longest one-act play ever staged in Polish theatre”, considers a problem of a fault and a punishment. The third one, similarly to the first one, presents folk beliefs in supernatural phenomena which take place on All Souls’ Day. Moreover, it partly resembles a mystery play. Although the trilogy got an unfavourable reception (it was shown only seven times in Juliusz Słowacki Theatre in Kraków), it may be considered as an ambitious attempt to match the heritage of Stanisław Wyspiański – according to Grabiński, the greatest authority in the field of theatre.
