Effect of lipophilization on functional properties of palm kernel flour (Elaeis guineensis)

open access: yesGrasas y Aceites, 2005
Functional properties of proteins presented in palm kernel flour were studied, started with almonds with and without testa. Removal of testa with HCl permitted a decrease of the polyphenol concentration, besides conferring the flour a light cream color ...

Dual asymmetric centrifugation to prepare cosmetic emulsions and creams: Physico‐chemical and energy considerations

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Dual asymmetric centrifugation (DAC) enables the preparation of stable cosmetic emulsions and structured creams with physicochemical, rheological and textural properties comparable to those of conventional processes. At larger scales, DAC also offers competitive energy efficiency by avoiding heating steps, supporting more sustainable cosmetic ...
