These fats can be prepared from vegetable oils by hardening through hydrogenation. However, this process causes the production of unhealthy trans-fatty acids as a by-product [20]. The other alternative is based on the use of palm oil. Palm oil is rich in palmitate and has been extensively used for human nutrition. It is also a very productive crop [19,21]. However, the increased cultivation of palm trees in Indonesia is causing destruction of broad areas of tropical forest (accompanied by smoke pollution) giving ecological concerns to the production of these fats. There is some controversy as to whether high dietary palmitic acid can have an effect on plasma lipoproteins. However, no such potentially negative effects have been attributed to stearic acid. Thus, fats enriched in stearic acid, like high stearic sunflower, seem to be a promising alternative for a sustainable and ‘healthy’ source of solid fats. However, the original high stearic sunflower lines also contain high levels of linoleic acid, which diminishes
