Layer-by-layer assembly of food-grade alginate/chitosan nanolaminates: formation and physicochemical characterization
(Springer Science+Business Media New York, 2017)The alternate deposition of oppositely charged materials (layer-by-layer technique) is an effective approach to functionalize materials. Biopolymer-based nanolaminates obtained by the layer-by-layer technique can also be ... -
Mineral and fatty acid profile of high intensity pulsed electric fields or thermally treated fruit juice-milk beverages stored under refrigeration
(Elsevier, 2017)The influence of High Intensity Pulsed Electric Fields (HIPEF) or Thermal Treatment (TT) on minerals and fatty acids of fruit juice-whole (FJ-WM) or skimmed milk (FJ-SM) beverages was assessed after processing and during ... -
Formation, stability and antioxidant activity of food-grade multilayer emulsions containing resveratrol
(Elsevier, 2017)Interfacial deposition of biopolymer layers on oil droplets may be a suitable strategy for increasing the emulsion stability and protection of functional ingredients. Resveratrol is a naturally occurring phenolic compound ... -
American millstones similar to the French burr: 19th century attempts to find substitutes
(Universitat de Lleida. Departament d'Història. Secció d'Arqueologia, Prehistòria i Història Antiga, 2019)During the early to mid 19th century, attempts were made in the United States to locate local sources of stone that were comparable in texture or appearance to that of the well known French burr millstone. These searches ... -
Effect of pulsed light treatments on quality and antioxidant properties of fresh-cut strawberries
(Elsevier, 2018)Fresh-cut strawberries were subjected to pulsed light treatments (4, 8, 12 and 16 J·cm−2) combined with a stabilizing dip. Quality changes and antioxidant properties were evaluated for 14 days at 5 °C. The treatments delayed ... -
Widespread North American ocuurence of millstones made of imported French chert (French buhr) containing charophytes
(Universitat de Lleida. Departament d'Història. Secció d'Arqueologia, Prehistòria i Història Antiga, 2019)Fossil charophytes belonging to the genus Gyrogona can be used to distinguish chert millstones made of French buhr (pierre meulière) from millstones made of domestic North American cherts. The occurrence of the charophytes ... -
Antioxidant activity of thermal or non-thermally treated strawberry and mango juices by Saccharomyces cerevisiae growth based assays
(Elsevier, 2016)The antioxidant activity of strawberry or mango juice [untreated or treated by high intensity pulsed electric fields (HIPEF) or heat] has been studied on a Saccharomyces cerevisiae yeast strain exposed to different oxidants ... -
Photo-protection and controlled release of folic acid using edible alginate/chitosan nanolaminates
(Elsevier, 2018)The formation, characterization, photo-protective properties and release profiles of folic acid-loaded nanolaminated films were investigated by UV-visible spectroscopy, FTIR, Raman and SEM microscopy. Food-grade alginate/chitosan ... -
Antimicrobial activity of nanoemulsions containing essential oils and high methoxyl pectin during long-term storage
(Elsevier, 2017)The antimicrobial activity against Escherichia coli and Listeria innocua of nanoemulsions containing oregano, thyme, lemongrass or mandarin essential oils and high methoxyl pectin was assessed during a long-term storage ... -
Influence of mandarin fiber addition on physico-chemical properties of nanoemulsions containing β-carotene under simulated gastrointestinal digestion conditions
(Elsevier, 2017-05-29)There is a lack of knowledge about how soluble fiber used as stabilizer may influence physicochemical properties of nanoemulsions during the lipid digestion process. In this study, different concentrations of mandarin fiber ... -
Norwegian millstone quarries in the face of European competition and cooperation 18th - 19 centuries
(Universitat de Lleida. Departament d'Història. Secció d'Arqueologia, Prehistòria i Història Antiga, 2019)Although geographically outside the heart of Europe, Norwegian millstone production was far from isolated from the rest of the continent. This article is based on research undertaken in French historical archives, a ... -
