The Bachelor’s thesis deals with the composition of vegetable oils, their production and legislative requirements related to this issue. It focuses on eight selected non-traditional types of cold pressed oils - flaxseed, hemp, poppy, safflower, pumpkin,avocado, grape and sesame. It describes their fatty acid composition and the content of biologically active compounds. All selected oils are characteristic by high levels of polyunsaturated fatty acids. Polyunsaturated fatty acids have positive effect on nutrition and predetermine the use of these oils especially in cold dishes. In addition to compounds such as tocopherols and phytosterols, which have been found in all oils, compounds specific to the given oil type have been described. For example, flaxseed oil contains lignan SDG, hemp oil contains cannabidiol, and pumpkin oil contains squalene. Biologically active compounds contained in these vegetable oils contribute to the improvement of human health and therefore even less traditional oils should become part of human diet. |
