Detection of Acetoin and Diacetyl by a Tobacco Mosaic Virus-Assisted Field-Effect Biosensor

Chemosensors, 2022
Acetoin and diacetyl have a major impact on the flavor of alcoholic beverages such as wine or beer. Therefore, their measurement is important during the fermentation process. Until now, gas chromatographic techniques have typically been applied; however,

Aquafaba (Chickpea Cooking Water) as a Natural Emulsifier in the Development of Plant‐Based Coffee Whitener

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, the possibility of using aquafaba powder, derived from chickpea cooking water, as a natural emulsifier in the formulation of plant‐based coffee whitener was evaluated. For this purpose, coffee whiteners, which are emulsion type products, are obtained by high‐shear mixing followed by high‐pressure homogenization of the aqueous ...
