Hardening Vegetable Oils Through Hydrogenation

The video tutorial explains margarine as an emulsion of water in oil, focusing on its production and properties. It covers the hydrogenation of polyunsaturated vegetable oils, which affects the consistency of margarine. Partial hydrogenation results in softer margarine, while more hydrogenation leads to a harder product. The tutorial also discusses the salty taste of margarine due to the presence of salty water droplets and the role of emulsifiers like lecithin. The video concludes with a summary of margarine's composition and the impact of hydrogenation on its properties.
