Characterization of peanut (Arachis hypogaea L.) seed oil and fatty acids composition under different growing season under mediterranean environment

Abstract

KEYWORDS Arachis hypogeal Fatty acid Growing season Iodine value Oleic linoleic acid ABSTRACTPeanut is one of the most important oil and protein producing crops in the world. Quality of peanut seed oil is influenced by temperature and moisture. However, little is known about the chemical composition of peanut grown in environmental conditions of Turkey. Therefore, this study was conducted at the Cukurova University Farm, Turkey as a main and double cropped to determinate oil quality and fatty acid compositions of some peanut varieties in different growing seasons. The results of study indicated that, the oil content (two years average) of peanut varieties ranged from 47.55-51.55% in main cropped and 43.71-50.48% in double cropped growing seasons. Further, the oleic acid content was also varied between 39.80-81.13% and 39.42-81.51% in main and double cropped growing seasons, respectively and the linoleic acid percentage values of peanut varieties ranged from 1.73 to 36.38% in main cropped and from 2.66 to 37.72% in double cropped growing season. Oleic acid to linoleic acid ratio (O/L) was higher in main cropped than in double cropped growing season and iodine value was higher in double cropped than in main cropped growing season.

“…Moreover, oil and protein content were decreased in the next cropping seasons of 2014.These results are in partial agreement with the findings of Gulluoglu et al (2016) who found the oil content among peanut varieties was insignificant in main cropped growing season. On the other hand, Islam et al (2016) observed that lower plant population produced the higher percentage of protein and oil content.…”

A comparative study of fatty acid extraction methods of sesame (Sesamum indicum L.) varieties grown under mediterranean environment

“…Water (Alpaslan et al, 2001) and temperature also influenced the oil content of sesame (Rondanini et al, 2003). Another studies revealed that oil content was influenced under diferent conditions in diferent crops (EL Sabagh et al, 2015Gulluoglu et al, 2016).…”

Assessment of growth and productivity of five peanut cultivars and genetic diversity using RAPD markers

“…Similar results were obtained by Mahrous et al (2015) who found that Gregory cultivar showed the highest seed oil content (52.22 %). Also, Gulluoglu et al (2016) found that oil content of peanut cultivars varied between 46.96 and 51.55 % based on dry weight of seeds and the highest oil content value (51.55%) was reported in Georgia Green cultivar, while the lowest one (46.96%) was noticed in Flower-22 cultivar.…”
