Effect of Selected Thickeners on Oil Droplet-Size Distribution in Low-Fat Emulsions

Abstract:  WPŁYW WYBRANYCH ZAGĘSTNIKÓW NA ROZKŁAD KROPEL OLEJU W EMULSJACH NISKOTŁUSZCZOWYCHS t r e s z c z e n i e Celem pracy było określenie wpływu wielkości dodatku, rodzaju oraz układu zastosowanych zagęst-ników na rozkład kropel oleju w emulsjach niskotłuszczowych. W pracy zastosowano następujące zagęst-niki: hydroksyfosforan diskrobiowy (skrobia instant z kukurydzy woskowej, skrobia z tapioki), naturalne gumy (ksantanowa, guar, mączka chleba świętojańskiego). W otrzymanych emulsjach tłuszczowych oznaczono lepkoś… Show more

“…Kinetically stable emulsions can be formed by adding emulsifiers and/or thickening agents (proteins and hydrocolloids) to overcome the activation energy of the system . The conventional explanation for emulsion stabilization by such agents is their accumulation at the oil–water interface in the form of a densely packed layer, which may prevent droplet flocculation and coalescence by a steric mechanism .…”

“…Often, in order to increase the viscosity of the water-diffusing phase, macromolecular hydrophilic substances (its colloidal solutions are characterized by high viscosity) are added to this phase. [17,18] Both sensory and instrumental viscosity monitoring can provide information on the rheological changes taking place in the layout. Viscosity is therefore an indicator of durability and it is a significant physicochemical parameter in the cosmetics industry for profiling the form of a product.…”
