Oil content and fatty acids composition of poppy seeds cultivated in two localities of Slovakia

Abstract

Oil content, fatty acids profile, acid and saponification values of poppy seeds grown on two localities of the Slovak Republic were evaluated in the study. Statistically significant effects of locality, genotype and their interaction (P < 0.05) for numerous descriptors were proved by non-parametric tests. Results confirmed that variation in the analysed parameters was influenced by the colour of seeds. Ochre variety Redy contained the highest oil level in both localities (49.9 and 52.4%) and linoleic acid level (74.3 and 71.6%). White-seeded Racek and Albín had the highest acid value (2.8 and 2.4% of free fatty acids) and grey-seeded Malsar and blue-seeded Maratón contained the highest saponification value. Buddha, a high-morphine poppy variety, differed significantly in all monitored parameters. High negative interrelation between linoleic and oleic acids levels was observed. Oil content was positively correlated with linoleic acid and negatively with oleic acid. Weather conditions at the end of vegetation influenced the accumulation of oil and essential linoleic acid.

Oil content and fatty acid profile of selected poppy (Papaver somniferum L.) landraces and modern cultivars

“…Duman and Özcan (2015) determined the average oil content of yellow poppy seeds to be 45.93%. Also, Lančaričová et al (2016) found that cultivars with ochre-coloured seeds contained the highest oil level, regardless of location.…”

“…The chemical composition of poppy seed is influenced by many factors, including genotype, climate, location and year of cultivation (Ghafoor et al 2019). Lančaričová et al (2016) concluded that the quality of poppy seeds depends on their genotype and especially on the locality of growing, that is, climatic conditions. The authors assumed, in line with our conclusions, that lower temperatures and greater precipitation can cause increased accumulation of oil.…”

“…age and transport of vitamins (Petrović et al 2010, Labdelli et al 2019. PUFA (polyunsaturated fatty acids) are prevailing fatty acids in poppy seed oil, mainly linoleic fatty acid, the amount of that ranges from 56.4-74.8% of all fatty acids (Bozan and Temelli 2008, Rahimi et al 2011, Lančaričová et al 2016). PUFA are one of the basic building blocks of human nutrition, and their intake is important for the proper functioning of the human body in terms of prevention of cardiovascular diseases, heart attacks and inflammatory diseases (Hlinková et al 2012).…”

“…PUFA are one of the basic building blocks of human nutrition, and their intake is important for the proper functioning of the human body in terms of prevention of cardiovascular diseases, heart attacks and inflammatory diseases (Hlinková et al 2012). Due to the high PUFA content, poppy seeds and poppy products are prone to autooxidation, which can lead to unpleasant odours and bitter tastes (Lančaričová et al 2016). As far as to the other fatty acids, poppy seed oil contains MUFA (monounsaturated fatty acids), mainly oleic acid (13.2-17.8%) (Erinç et al 2009, Rahimi et al 2011) and palmitoleic acid (0.17-0.40%) (Hlinková et al 2012, Özbek andErgönül 2020).…”

Molecular and Biological Characterisation of Turnip mosaic virus Isolates Infecting Poppy (Papaver somniferum and P. rhoeas) in Slovakia

“…Originating from Asia Minor or from the Western Mediterranean region, oilseed poppy cultivation covers a wide geographic area around the world due to the adaption of this species to various climatic conditions as a result of its long history of domestication and breeding. The oilseed poppy is legally grown in Slovakia for the seeds used as an ingredient in some foods and for the seed capsules containing several alkaloids, including morphine, codeine, papaverine, and thebaine, valuable in the pharmaceutical industry [ 1 , 2 , 3 ]. On the contrary, common poppy is a red-flowering agricultural weed abundantly spread in Europe [ 4 ].…”
