Consumers want to know that the foods they consume provide health benefits. Food materials science can monitor changes during digestion as well as assist in the development of low-fat products.
Foods rich in resistant starch (starch that resists digestion until reaching the large bowel) can provide multiple benefits including improved insulin sensitivity, lower blood sugar levels, and a healthy gut microbiome.
Oleogels can be used to replace conventional saturated fatty acid-based lipids with a healthier alternative. They immobilise liquid edible oils in a 3D network provided by an oleogelator. Researchers have identified numerous molecules which can provide structure to oils rich in (poly)unsaturated fatty acids. They have the ability to provide firmness to oil-rich foods, such as spreads, without the need for saturated fats.
Whether it is the optimisation of resistant starch levels in food products or the correlation between network formation and gel behaviour in oleogels, nuclear-based techniques can assist.
