High oleic sunflowers

from Wikipedia, the free encyclopedia

In high oleic sunflower (short-HO-sunflower) is, for varieties of sunflower ( Helianthus annuus ) with an oleic acid fraction of about 75-93% of the fatty acid residues in the triglycerides . They were bred the conventional way from a mutant found in Russia. The varieties currently being cultivated were not genetically modified.

Usage history

There has been a notable cultivation in Europe since the mid-1990s. In Germany, varieties with up to 93% oleic acid are now grown. The oil from the varieties with 75–90% is mainly used in nutrition. Due to the high proportion of monounsaturated fatty acid, oleic acid (C 18: 1), and the low proportion of polyunsaturated fatty acids , this oil is characterized by very high heat and oxidation stability . Therefore it is very suitable for the hot kitchen, for frying and deep-frying . The service life in the deep fat fryer is significantly longer and it practically does not get rancid.

Oil from types with over 90% oleic acid is mainly used in the technical area of ​​the chemical industry . Due to its extremely high oxidation and heat stability, it is particularly suitable for the production of lubricants. Hydraulic and special oils made from HO oils are clearly superior to most comparable mineral oil-based products. High oleic sunflower oil is also used in the cosmetics industry.

Examples of the fatty acid pattern in triglycerides

80 HO oil: 90s HO oil:
Palmitic acid (C 16: 0) 6.8%
Stearic acid (C 18: 0) 3.5%
Oleic acid (C 18: 1) 85.1%
Linoleic acid (C 18: 2) 3.9%
other <0.7%
Palmitic acid (C 16: 0) 3.5%
Stearic acid (C 18: 0) 1.5%
Oleic acid (C 18: 1) 92.3%
Linoleic acid (C 18: 2) 1.9%
other <0.8%
