Packaging also fosters effective marketing of the food through distribution and sale channels. It is of the utmost importance to optimize the protection of the food, a great quality and appearance - better than typical packaged foods. In recent years, intelligent packaging became very popular. Intelligent packaging is becoming more and more widely used for food products. Application of this type of solution contributes to improvement of the quality consumer life undoubtedly. Intelligent packaging refers to a package that can sense environmental changes, and in turn, informs the users about the changes. These packaging systems contain devices that are capable of sensing and providing information about the functions and properties of the packaged foods. Also, this paper will review intelligent packaging technologies and describe different types of indicators (time-temperature indicators, freshness indicators).

Opakowania umożliwiają efektywny marketing żywności przy zastosowaniu różnych kanałów sprzedaży i dystrybucji. Najważniejszym zadaniem jest optymalizacja ochrony żywności, jej jakości i wyglądu. W przeciągu ostatnich lat, wzrasta popularność opakowań inteligentnych, które zaczynają być stosowane dla coraz to większej liczby produktów żywnościowych. Zastosowania ich przyczyniają się do poprawy życia konsumenta. Określenie "opakowania inteligentne" stosuje się do opakowań wyczuwających zmiany w otoczeniu oraz będących w stanie informować o tych zmianach. Systemy opakowaniowe zawierają w sobie urządzenia wykrywające i dostarczające informacji dotyczących stanu zapakowanej żywności. Praca ta dokonuje przeglądu technologii opakowań inteligentnych oraz opisuje różnego rodzaju wskaźniki (temperatury, czasu i świeżości).

Sediment geochemistry and lithology were studied in Gostyń Lake in the eastern part of the Myślibórz Lakeland (part of the Western Pomeranian Lake District). The research was undertaken because relatively shallow lake basins without ground supply contribute to the intensification of water circulation through evaporation. Late Glacial and Holocene phases in the evolution of Gostyń Lake were reconstructed based on selected geochemical indicators (Fe/Mn, S/Fe, Na/K, Mg/Ca, Cu/Zn, Na+K+Mg/Ca, Fe/Ca) as well as on the presence of human activity (Stone Age, Bronze Age, Early Iron Age and Roman Period). Also, the geochemical and archaeological data were correlated. Generally, the lithogeochemical composition variability in the Gostyń Lake deposits was found to be controlled by changes in: 1) the climate, related to the biogenic accumulation environment, 2) land cover in the Late Glacial and Holocene, and 3) human activities. Principal Component Analysis (PCA) revealed four major variable groups responsible for the changes: hydroclimatic variations which determined the type of sedimentary conditions during the Holocene climate optimum; changes in the organic matter provenance (along with conditions favouring sulphide precipitation); and denudation processes in the Gostyń Lake catchment. The methods used allowed the distribution of ancient settlement to be traced. Interpretation of the geochemical indicators (Fe/Mn, Cu/Zn, S/Fe, Ca/Fe) should involve many more factors which, in the relevant literature, are treated as measures of changes in redox conditions
