    Opis:
    The influence of gelatin coatings modified with fungal melanin on pork lard oxidative stability was studied. The lard was coated with gelatin coatings containing 0.1%; 0.5%; 1% of fungal melanin and control gelatin coating devoid of melanin. The peroxide values (POV), iodine values (IV) and acid values (AV) were studied after 7, 14 and 21 days storage in controlled conditions. Lard covered with modified coatings had lowered oxidative rancidity. Hence, modified coatings containing fungal melanin can be use effectively for the prevention of lard oxidation.

    Opis:
    Fungal melanin was used to prepare gelatin-based composite films. The films of various melanin concentrations (0.1%, 0.5% and 1% w/w) were prepared using a solution casting method. The mechanical, antioxidant, antimicrobial, water vapor, oxygen and UV-Vis barrier properties, as well as any available surface polyphenolics were studied. FT-IR and Raman spectroscopy studies were carried out to analyse the chemical composition of the resulting films. The hydrophobocity, solubility, colour response, optical properties and opacity were also determined. The results of this study showed that the modification of gelatin with fungal melanin had no influence on mechanical and water vapor barrier properties, oxygen barrier properties were improved. The UV-Vis barrier properties of modified films were significantly improved. Modified gelatin films showed good antioxidant activity but were inactive against microorganisms. The modification with melanin caused changes in colour values, decreasing lightness and increasing the redness and yellowness of the films. Based on the results of this study, fungal melanin has good potential to be utilised as a value-added modifier that can improve the properties of gelatin films.

    Opis:
    The goal of the study was to determine the influence of encapsulation, immobilization conditions and packaging on microorganisms survival. The results of the study demonstrated that L. gasseri, L. plantarum, and L. rhamnosus as probiotics could be added to food products as lyophilized cells if the end product was stored at 25 °C for no longer than 3 months. It was shown that L. plantarum and L. rhamnosus as food additives could be stored 6 months in room temperature, only if the cells were encapsulated or if the end product was packed in MAP. It was proved that the number of probiotics immobilized in the chamber was higher than the number of bacteria immobilized at aerobic conditions with higher relative humidity. Cocoa butter, presented in this study could be used as an immobilization carrier due to its hydrophobicity.
