Abstract:
... The removal of plant pigments such as β-carotene is an aspect of vegetable oil processing often desired by the food and pharmaceutical industries. Adsorption of β-carotene to acid-activated clay (AAC) is a well-established method for purification. Despite this, the removal mechanism of β-carotene is not well understood. UPLC-MS/MS analysis of surface compounds extracted from β-carotene-AAC (BC-AAC ...

Abstract:
... We demonstrate that γ-oryzanol at concentrations as low as 7 wt% can structure vegetable oil. At a temperature below its crystallization onset, quiescent processing does not result in oil structuring, given the formation of γ-oryzanol crystal spherulites upwards of 100 μm in diameter that do not associate to form a continuous network. Rather, concurrent mixing and cooling are necessary to form a γ ...
