Berries and berry production are an important economic factor. contain nutritive components but also pertinent non-nutritive bioactives like phenolic-type phytochemicals. It is well accepted that consumption of from berries prevent
To determine the effects of different processing steps, such as enzymatic treatment mash and pasteurization, on selected quality parameters, strawberries were processed to juices purees. identify steps causing highest losses, samples taken after each step, ascorbic acid, total phenols, anthocyanins, antioxidant capacity analyzed. assess capacity, three methods applied: trolox equivalent (TEAC), ferric reducing power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, showing correlation...
Technologies for controlling microbial risks in a heat and humidity sensitive food powder are still limited. To preserve bioactive compounds while inactivating Bacillus subtilis spores powdered Spirulina microalgae (Arthrospira platensis) with non-thermal atmospheric plasma is the challenge presented this paper. Artificially contaminated was treated custom-made surface micro-discharge cold pressure (SMD-CAPP) at effective, specific energy of (Es) 7–15 mW/cm2. The inactivation air faster than...
Rosehip is of notable scientific interest due to its rich content bioactives and wide-ranging applications in nutrition, cosmetics pharmaceuticals. The valorization rosehip by-products, such as pomace, highly significant for promoting sustainability. This study investigates the development rosehip-based powders beverage prototypes derived from both juice pomace evaluate potential use instant design compare it with juice-based formulations. Three matrices were evaluated: non-pasteurized...
Uptake and intestinal metabolism of physiologically active genistin were studied in an ex vivo perfusion model; luminally applied concentrations 5.9, 12.0, 23.8 μmol/l. The absorption was 14.9% (±2.3, n =9), irrespective the amounts applied. majority absorbed appeared as genistein glucuronide (11.6%), also recovered main metabolite on luminal side (19.5%). Minor (1.3%) (1.9%) found vascular side, whereas 15.4% cleaved to yield genistein. Sulfate derivatives or not observed.
Little is known about the change of phenolic compounds and total content by acetification process. The aim this study was to assess contents selected cider red white wines in comparison profiles corresponding vinegars using a new HPLC method for simultaneous separation quantification polar acids less flavonoids. Identifications were made retention times means mass spectra. Additionally, determined photometrically. decrease phenol process highest (40%) lower wine (13 8%, respectively). A...
