Kernel Oil

Seed of California almond [Prunus dulcis (Mill.) D.A. Webb, syn. P. amygdalus Batsch, and P. communis (L.) Arcangeli, non-Huds.] genotypes contained very low saturated fatty acids, high monounsaturated fatty acids, and low polyunsaturated fatty acids. Kernel oil consisted primarily of five fatty acids: palmetic, palmetoleic, stearic, oleic, and linoleic. Linolenic acid was only present in amounts of <0.02% and only in a few samples. Small but significant differences among genotypes and sampling sites were found in the proportions of palmetic, palmetoleic, and stearic fatty acids. The major differences in fatty acid composition among genotypes was found in the proportions of oleic, a monounsaturated fatty acid, and linoleic, a polyunsaturated fatty acid. The proportion of oleic acid was highest, ranging from ≈62% to 76%, and was highly and negatively correlated with linoleic acid levels. Usable genetic variation and a significant genotype × environment interaction were identified for oil content and composition. The introgression of new germplasm from peach and related species does not appear to reduce oil quantity or quality, and may offer opportunities for further genetic improvement of kernel oil composition.

Cold-pressed seed oil from twelve commercially produced cactus pear cultivars was assessed for oil yield, fatty acid composition, physicochemical properties, quality and stability. Large differences in oil content, fatty acid composition and physicochemical properties (IV, PV, RI, tocopherols, ORAC, % FFA, OSI and induction time) were observed. Oil content ranged between 2.51% and 5.96% (Meyers and American Giant). The important fatty acids detected were C16:0, C18:0, C18:1c9 and C18:2c9,12, with C18:2c9,12, the dominating fatty acid, ranging from 58.56-65.73%, followed by C18:1c9, ranging between 13.18-16.07%, C16:0, which ranged between 10.97 - 15.07% and C18:0, which ranged between 2.62-3.18%. Other fatty acids such as C14:0, C16:1c9, C17:0, C17:1c10, C20:0, C18:3c9,12,15 and C20:3c8,11,14 were detected in small amounts. The quality parameters of the oils were strongly influenced by oil content, fatty acid composition and physicochemical properties. Oil content, PV, % FFA, RI, IV, tocopherols, ORAC and ρ-anisidine value were negatively correlated with OSI. C18:0; C18:1c9; C18:2c9,12; MUFA; PUFA; n-6 and PUFA/SFA were also negatively correlated with OSI. Among all the cultivars, American Giant was identified as the paramount cultivar with good quality traits (oil content and oxidative stability).

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

Abstract Seed samples of some rape and canola cultivars were analysed for oil content, fatty acid and tocopherol profiles. Gas liquid chromotography and high performance liquid chromotography were used for fatty acid and tocopherol analysis, respectively. The oil contents of rape and canola seeds varied between 30.6% and 48.3% of the dry weight (p<0.05). The oil contents of rapeseeds were found to be high compared with canola seed oils. The main fatty acids in the oils are oleic (56.80–64.92%), linoleic (17.11–20.92%) and palmitic (4.18–5.01%) acids. A few types of tocopherols were found in rape and canola oils in various amounts: α-tocopherol, γ-tocopherol, δ-tocopherol, β-tocopherol and α-tocotrienol. The major tocopherol in the seed oils of rape and canola cultivars were α-tocopherol (13.22–40.01%) and γ-tocopherol (33.64–51.53%) accompanied by α-T3 (0.0–1.34%) and δ-tocopherol (0.25–1.86%) (p<0.05). As a result, the present study shows that oil, fatty acid and tocopherol contents differ significantly among the cultivars.

The main purpose of this study is to characterise how substrate lipid content affects growth kinetics of black soldier fly (BSF) larvae. Growth curves of larvae were characterised in substrates composed of chicken feed supplemented by 0-30% fish oil, and lipid content and fatty acid composition of the prepupae were quantified to examine up-take and assimilation of fish oil by the larvae. Increasing contents of fish oil resulted in reduced specific growth rates, reduced weight of the prepupae, and increased mortality. The prepupae had similar lipid contents at 0-20% fish oil, while 30% fish oil increased the lipid content of prepupae. In contrast, the fatty acid composition of the prepupae showed a strong dependency on substrate fish oil content, indicating that the larvae increased their uptake of fish oil with increasing fish oil content. C16-C22 fatty acids were bioaccumulated from the fish oil, but particularly C20 and C22 fatty acids were apparently also shortened or further metabolised. Microbial fermentation products rapidly accumulated in the substrates, and substrate lipids and carbohydrates were preserved and remained available for the larvae throughout their growth period. These results point out that although BSF larvae can utilise high contents of substrate lipids, it may be at the expense of reduced growth performance, and with limited effects on the composition of their biomass.
