Measuring the Oil-Binding Characteristics of Flour.

Cereal chemists are well aware that different flours may exhibit wide variations in water absorption capacities. That flour can exhibit a strong affinity for fats is also generally recognized by the difficulty of extracting fat from doughs and baked products without resort to add hydrolysis. Two methods for measuring oil-binding characteristics of flour are described. With increasing protein content, oil-binding capacity increases. That this effect is not entirely explained by an interaction between protein and oil is demonstrated by an experiment in which the oil-binding capacity of wheat starch was increased by a chlorine bleaching treatment. That the phenomenon is physical rather than chemical is demonstrated by the observation that comparable oil-binding measurements are obtained regardless of whether the oil is a comparatively unsaturated triglyceride, a saturated triglyceride, or a hydrocarbon (mineral) oil.
