“…The CAS-14 mutant line has more stearic acid (37.3%) than the previous highstearic-acid sunflower mutants like CAS-3 which had 28.8% stearic acid (Fernandez-Moya et al 2002;Osorio et al 1995). Due to the sensitivity of desaturases to temperature, high temperatures increase the content of monounsaturated fatty acids (C18:1) (Merrien et al 2005). An effect of temperature on the high-stearic-acid sunflower mutants was observed.…”

Palm oil is widely used in the food industry because of its lower cost, high oxidative stability index, long shelf-life, and a reasonable replacement of trans fats. However, increased palm oil production reduces biodiversity, damages the ecosystem, and poses health risks to humans. Unsustainable development of palm plantations has caused deforestation and loss of natural habitat, rendering many species (Sumatran orangutans, elephants, and tigers) critically endangered. Similarly, decomposition and burning of carbon-rich soil in vast and deep peatlands is increasing carbon emissions. Furthermore, excessive consumption of palmitic acid (and other saturated fats except stearic acid) increases bad cholesterol and the risk of cardiovascular diseases. Therefore, we need healthier, stable, and solid/semisolid oils at room temperature with longer shelf-life and without trans fats. Here, we review the advancements in the development of sunflower oil varieties containing high stearic (∼18%) and high oleic (∼70%) acids which makes them healthy and sustainable alternatives to palm oil. First, the high-stearic-high-oleic sunflower crops can have grain and oil yield as high as 4036 and 1685 kg/ha and oleic and stearic acid yield up to ∼73 and ∼21%. Second, high-stearic-high-oleic oils obtained from mutant and hybrid sunflower cultivars have higher oxidative stability index and therefore have better stability, quality, and functionality than regular sunflower oil. For example, the oxidative stability index of commercially available Nutrisun at 110°C is six times greater than that of regular sunflower oil. Finally, recent advances have made several mutant and hybrid cultivars with high grain and oil yield and high levels of stearic and oleic acids available. Given this progress, natural healthy high-stearic-high-oleic sunflower oil can now be grown in both the hemispheres in a sustainable manner with the currently available advanced technology and without damaging the ecosystem as is currently happening with palm oil cultivation.

Interesterification becomes a very powerful tool in food industry. A blend of coconut oil and palm stearin is enzymatically interesterified by lipase (EC 3.1.1.3) in an aquarium reactor. The interesterified blend obtained is then incorporated in madeleines, mini croissants, and mini rolls. Physicochemical parameters’ assessment for molasses used is in good agreement with the international standards. Fatty acid composition of the interesterified blend and sugar content of molasses were assessed by gas chromatography (GC) and high performance liquid chromatography (HPLC). A sensory evaluation of the madeleines, mini croissants, and buns has been carried out by untrained tasters, with a statistical analysis by a principal component analysis (PCA). Chromatographic characterization by Gas Chromatography revealed fatty acids, ranging from C6: 0 to C22: 0. Liquid sugar’s content by high performance liquid chromatography revealed three main sugars: sucrose, glucose, and fructose. Results of the sensory analysis showed the good quality of the prepared products.

“…Используя эти сведения, ряд учёных представили доказательства того, что можно объяснить изменение состава жирных кислот в подсолнечном масле по разным местам во Франции. Была получена сильная корреляция между минимальной температурой в этот период и содержанием жирных кислот в масле [3]. Похожие работы проводились и отечественными исследователями, в результате чего были опубликованы данные, в которых сообщается, что между содержанием линолевой кислоты в период интенсивного маслообразовательного процесса и минимальной суточной температурой воздуха накануне проведения отбора проб у форм подсолнечника с обычным генотипом по составу жирных кислот существует высокая отрицательная корреляция.…”

Middle content of oleic acid in high oleic lines of winter rapeseed in hot 2019 was maximal and equal to 81.2 %, and minimal one – in a cool 2017 – 75.3 %. Studying of influence of day and night air temperatures in a period of seed formation (19.0–32.4/10.6–24.0 °С) on oil and glucosinolate contents in seeds of high oleic winter rapeseed did not demonstrated any significant dependences between these traits. There were not observed any important relations between amount of precipitations in a period of seed formation and oil content, fatty-acid composition of oil and glucosinolatec content in high oleic winter rapeseed.
