Bread is often associated with refined flour and a higher glycaemic response, but not all loaves behave in the same way. Ingredient choice, formulation, and fat selection can all influence texture, nutrition, and how steadily energy is released after eating.

Frying performance depends not only on cooking outcome, but also on how well an oil maintains its stability under heat. Comparative studies on palm olein have examined its performance during repeated frying, both as a blend and against other edible oils, with results indicating its functional and nutritional relevance in frying applications.

Repeated frying is a common practice in many households and food preparation settings. In this context, oil stability matters, as repeated heating can accelerate oxidation and contribute to the formation of undesirable compounds.
