The rapidly growing demand for organic food requires the availability of analytical tools enabling their authentication. Recently, metabolomic fingerprinting/profiling has been demonstrated as a challenging option comprehensive characterisation small molecules occurring in plants, since pattern may reflect impact various external factors. In two-year pilot study, concerned with classification versus conventional crops, ambient mass spectrometry consisting direct analysis real time (DART) ion...
This work investigates the thermal stability of bacteriocin nisin in polylactide (PLA) and polylactide/polyethylene glycol (PLA/PEG) blends at temperatures 90 °C–180 °C. The samples were prepared by solvent cast technique characterized according to their mechanical properties. Research on PLA PLA/PEG systems was carried out exposing given films various (90 °C, 120 160 180 °C) for a duration up 48 h. Assessment antibacterial activity agar diffusion method against Micrococcus luteus, while...
Chicken collagen is a promising raw material source for the production gelatins and hydrolysates. These can be prepared biotechnologically using proteolytic enzymes. By choosing appropriate process conditions, such changes achieved at molecular level of collagen, making it possible to prepare with targeted properties advanced cosmetic, pharmaceutical, medical, or food applications. The present research aims investigate model samples chicken gelatins, focusing on: (i) antioxidant activity...
This work describes the synergetic effect of polyethylene glycol (PEG) in polylactide (PLA) blends, wherein polyether acts as both plasticizer and functional additive, ensuring long‐term antimicrobial activity bacteriocin nisin. Two types PEG with molecular weights 1000 6000 g.mol −1 (20 wt.%) were used to plasticize PLA blends. The aforementioned nisin, at concentrations ranging between 0.02 0.15 wt.% (8000‐60 000 IU.g ), was incorporated into samples by solvent cast technique. various on...
The aim of the study was to determine possible changes in isofl avones concentration cheese made from either control or avone-enriched milk during manufacturing and ripening.The experiment carried out on four high-yielding lactating Holstein cows that were divided into two groups with similar mean yield.The group fed a diet based extruded rapeseed cake (C) while experimental animals full-fat soya (S).The form cross-over design 2 periods 14 days (a 10-d preliminary period 4-d period).Cows...
Poly(ethylene oxide) (PEO)-like thin films were successfully prepared by plasma-assisted vapor thermal deposition (PAVTD). PEO powders with a molar weight (Mw) between 1500 g/mol and 600,000 used as bulk precursors. The effect of Mw on the structural surface properties was analyzed for at lower plasma power. Fourier transform (FTIR-ATR) spectroscopy showed that molecular structure well preserved regardless stronger impact process conditions (the presence/absence plasma) proved. Molecular...
Chicken collagen is a promising raw material source to produce gelatins and hydrolysates. Gelatins hydrolysates can be prepared biotechnologically using proteolytic enzymes produced by submerged fermentation of genetically modified microorganisms. By choosing the appropriate process conditions, such changes achieved at molecular level collagen, making it possible prepare products with targeted properties for advanced cosmetic, pharmaceutical, medical or food applications. The research aims...
