AB  - In this study, in order to develop zein-based, edible, functional food-contact materials in different forms incorporating sage extract (10, 20, and 30%), solvent casting and electrospinning were employed. The study aimed to assess the effects of the applied techniques and the extract's incorporation on the materials' properties. The solvent casting generated continuous and compact films, where the extract's incorporation provided more homogenous surfaces. The electrospinning resulted in non-woven mats composed of ribbon-like fibers in the range of 1.275-1.829 mu m, while the extract's incorporation provided thinner and branched fibers. The results indicated the compatibility between the materials' constituents, and efficient and homogenous extract incorporation within the zein matrices, with more probable interactions occurring during the solvent casting. All of the formulations had a high dry matter content, whereas the mats and the formulations incorporating the extract had higher solubility and swelling in water. The films and mats presented similar DPPH center dot and ABTS(center dot+) radical scavenging abilities, while the influence on Staphylococcus aureus and Salmonella enterica subsp. enterica serovar Typhimurium bacteria, and the growth inhibition, were complex. The antioxidant and antibacterial activity of the materials were more potent after the extract's incorporation. Overall, the results highlight the potential of the developed edible materials for use as food-contact materials with active/bioactive functionality.

AB  - The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for the removal of Pb2+, Cd2+ and Ni2+ from aqueous solution. The materials were characterized by FT-IR, Raman, SEM and EDS analysis and by determination of pH(PZC). The adsorption performances of Sa and SaHAp were assessed in batch experiments at different pH, contact times, temperatures and mass of the adsorbent. Different models of adsorption isotherms were used, and the best fit was obtained with the Langmuir model. Maximum adsorption capacities of Sa towards Pb2+, Cd2+ and Ni2+ were 44.82, 15.54 and 17.21 mg g(-1), while for Sa-HAp were 79.55, 52.59 and 45.01 mg g(-1), respectively. Kinetic data were well fitted by a pseudo second-order model, while thermodynamic studies disclose spontaneous and endothermic adsorption process. The Sa-Hap was successfully regenerated with 1 M NaCl and after the fifth desorption cycle and 10 h achieved 82.9, 69.7 and 60.4 %, while for 0.5 M NaCl + 0.5 M NaOH and 1 h was 78.3, 64.1, 57.5 % of desorbed Pb2+, Cd2+ and Ni2+, respectively. The competitive study and results from a column system confirmed good applicability of Sa-HAp adsorbent.

AB  - Poly(vinyl alcohol) (PVA) was investigated as a carrier for Lactobacillus rhamnosus ATCC 7469 cells for application in L-(+)-lactic acid (LA) fermentation on low-cost food industry by-products. Brewer?s spent grain (BSG) and malt rootlets (MR) hydrolysates, with the addition of brewer?s yeast, brewer?s yeast extract, or malt rootlets extract and soy lecithin were evaluated as media for LA fermentation. PVA concentrations of 5, 10 and 15% were evaluated and the optimal concentration was further used. Obtained PVA biocatalyst (BC) was applied in batch and repeated batch fermentations of BSG and MR hydrolysate. During 12 consecutive batch fermentations, the BC showed high mechanical stability and minor loss of activity while achieving high LA yield (97%) and productivity (2.1 g/L h-1). The study suggests that the immobilized L. rhamnosus cells in PVA cryogel can be successfully used in stable repeated batch fermentations on low-cost fermentation media without the loss of cell activity and LA fermentation capability.

AB  - Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell-DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (EL) and Tannic acid (TA), as an additional crosslinker, were developed for the production of the bio-renewable Cell-EL and Cell-EL-TA membranes. The influences of pH, contact time, adsorbent dose, and temperature on adsorption performances were studied by batch adsorption tests. The calculated capacities: 53.9, 99.9, 97.8 and 63.5, 115.8, 127.5 mg g(-1) for Ni2+, Pb2+, Cr(VI) using Cell-EL and Cell-EL-TA, respectively, were obtained from Langmuir model fitting at 25 degrees C. The thermodynamic parameters indicated spontaneous and low endothermic processes. The results of the kinetic study, i.e. pseudo-second-order (PSO) and Weber-Morris (W-M), suggest an intra-particle diffusion as a rate-limiting step. The semi-empirical quantum chemical calculations aided the analysis of the non-specificand specific adsorbent/adsorbate interactions and their contribution to the overall bonding mechanism. Membrane utility was confirmed by performing a bed column study. In general, three main environmental issues of the present study, biodegradability of the used membrane, desorption efficiency, and development of the technology for the effective effluent water treatment and safe disposal of by-products highly conform to the demand of integrated environmental management system applicability in practice.

AB  - Despite numerous challenges, encapsulation technologies are likely to become increasingly the focus of the food industry, because of their advantages for certain applications, for example, taste masking, limiting oxidation, increasing bioavailability, or controlling the release of active ingredients in food and functional food products. This chapter gives a summary of encapsulation technologies that can be adopted by food manufacturers aiming to develop effective nutrient delivery systems. The main groups of encapsulation technologies are described and compared from the engineering aspect, that is, the impact of process conditions on resulting properties of encapsulates composition (structure, dimensions, interfacial properties, loading, and stability). Besides, their advantages and drawbacks are listed to get a critical point of view on existing and future industrial applications. Finally, along with a comprehensive review of research insights focused on the implementation of produced encapsulates in food products, this chapter provides examples of main patents based on described encapsulation technologies.
