Critical water activity and critical water content of freeze-dried strawberry powder as affected by maltodextrin and arabic gum

Mosquera, Luz Hicela; Moraga Ballesteros, Gemma; Martínez Navarrete, Nuria (Elsevier, 2012-07)

The adsorption isotherms (20 °C) and the relationship between water content and glass transition temperature were modeled in freeze-dried strawberry powder studying the effect of the addition of maltodextrin and arabic ...
Development and characterization of unmodified kaolinite/EVOH nanocomposites by melt compounding

Cabedo Mas, Luis; Villanueva Redon, María Pilar; Lagaron Cabello, José María; Giménez Torres, Enrique (Elsevier, 2017)

[EN] Nanocomposites of unmodified kaolinite (Kaol)/ethylene-vinyl alcohol copolymer (EVOH) with different Kaol contents have been obtained by a two-step process: melt blending in an internal mixer and film processing by ...
Stability of biocontrol products carrying Candida sake CPA-1 in starch derivatives as a function of water activity

Marín-Gozalbo, Anna; Atarés Huerta, Lorena María; Cháfer Nácher, María Teresa; Chiralt, A. (Taylor & Francis, 2017)

[EN] The preservation and shelf-life of formulations of the biocontrol agent Candida sake CPA-1 and starch derivatives as a function of water activity (aW) were studied in terms of the physical stability of the products ...
Water activity and glass transition effect on the physical properties and bioactive compounds of persimmon peel powder

Hosseininejad, Seyedehsepideh; Larrea Santos, Virginia; Quiles Chuliá, Mª Desamparados; Hernando Hernando, Mª Isabel; Moraga Ballesteros, Gemma (Blackwell Publishing, 2024-02-14)

[EN] The storage of the persimmon peel powder in a glassy state (at 20 degrees C below aw = 0.218 and 0.028 g water g-1 product) allows to have a loose and light powder with a high content of phenolic compounds and antioxidant ...
Water and polymer dynamics in poly(hydroxyl ethyl acrylate-co-ethyl acrylate) copolymer hydrogels

Kyritsis, A.; Spanoudaki, A.; Pandis, C.; Hartmann, L.; Pelster, R.; Shinyashiki, N.; Rodríguez Hernández, José Carlos; Gómez Ribelles, José Luís; Monleón Pradas, Manuel; Pissis, Polykarpos (Elsevier, 2011)

Water and polymer dynamics in hydrogels based on random copolymers of hydrophilic poly( hydroxyl ethyl acrylate) (PHEA) and hydrophobic poly(ethyl acrylate) (PEA), in wide ranges of composition, were investigated by means ...
Water interactions and microstructure of chitosan-methylcellulose composite films as affected by ionic concentration

Vargas, Maria; Albors, A.; Chiralt, A.; González Martínez, María Consuelo (Elsevier, 2011)

[EN] Edible films based on high molecular weight chitosan (CH) and methylcellulose (MC) were obtained by mixing different ratios (0:1, 0.5:1.5, 1.0:1.0, 1.5:0.5 and 1:0) of the biopolymers in two solvent conditions (0.95 ...
