- Presents a novel strategy to eliminate trans fats from our diets and avoid excessive amounts of saturated fat by structuring oil to make it behave like crystalline fat
- Reviews recent advances in the structuring of edible oils to form new mesoscale and nanoscale structures, including nanofibers, mesophases, and functionalized crystals and crystalline particles
- Identifies evidence on how to develop trans fat free, low saturate functional shortenings for the food industry that could make a major impact on the health characteristics of the foods we consume
