“…This was probably due to variation in organic solvents used in crude fat analysis. Besides, the lipid content can be affected by genetic and environmental factors (Izquierdo et al 2012). Roselle seed is an excellent source of culinary oil (Nyam et al 2009).…”

Roselle (Hibiscus sabdariffa L.) seed is a valuable food resource as it has an excellent source of dietary fibre. Therefore, this study examined the functional properties of roselle seeds. Replacement of cookie flour with roselle seed powder at levels of 0-30 % was investigated for its effect on functional and nutritional properties of cookies. Among the four formulations cookies, the most preferred by panelists was 20 % roselle seed powder cookie (F3), followed by 10 % roselle seed powder cookie (F2) and 30 % roselle seed powder cookie (F4). The least preferred formulation among all was control cookie (F1). Cookie with 20 % roselle seed powder added showed higher content of total dietary fibre (5.6 g/100 g) as compared with control cookie (0.90 g/100 g). Besides that, cookies incorporated with roselle seed powder exhibited improved antioxidant properties. Thus, roselle seed powder can be used as a dietary fibre source and developed as a functional ingredient in food products.

“…Concerning the effect of solar radiation, in “Nonpareil” almond kernels the concentration of α-tocopherol was increased after a mild solar UV radiation supplement using the white weed mat, which may have altered metabolic pathways and stimulated α-tocopherol accumulation in almond lipids [ 44 ]. In sunflower, it has been reported that an increase in intercepted solar radiation per plant increased the amount of tocopherol per grain [ 65 ].…”

Almond is the most important nut species worldwide and almond kernels show the highest levels of tocopherols among all nuts. In almond, tocopherols not only play a substantial role as a healthy food for human consumption, but also in protecting lipids against oxidation and, thus, lengthening the storage time of almond kernels. The main tocopherol homologues detected in almond in decreasing content and biological importance are α-, γ-, δ-, and β-tocopherol. Tocopherol concentration in almond depends on the genotype and the environment, such as the climatic conditions of the year and the growing management of the orchard. The range of variability for the different tocopherol homologues is of 335–657 mg/kg of almond oil for α-, 2–50 for γ-, and 0.1–22 for β-tocopherol. Drought and heat have been the most important stresses affecting tocopherol content in almond, with increased levels at higher temperatures and in water deficit conditions. The right cultivar and the most appropriate growing conditions may be selected to obtain crops with effective kernel storage and for the most beneficial effects of almond consumption for human nutrition and health.

“…A dilution relationship was also observed for oil tocopherol concentration in sunflower (González Belo et al, ; Nolasco et al, ) and other oilseed species, such as soybean and canola (Izquierdo et al, ). According to the adjusted equation in this work, considering all data points (Fig.…”

“…Previous studies have shown the influence of radiation on grain quality traits in sunflower. An increase in intercepted radiation during grain filling increased the amount of tocopherols and oil in sunflower grains (Izquierdo et al, ). As the oil increased more than tocopherols, these compounds had a lower concentration in the oil (González Belo et al, ).…”

Phytosterols are plant sterols that present several benefits for human health. In crop species, such as sunflower, oil phytosterol concentration shows genetic and environmental variations. The reasons that cause such varied concentration of phytosterols in the oil are unknown. The aim of this work was to investigate the relationships between phytosterol concentration and composition and grain oil content in sunflower. Two sets of samples, with lines and hybrids grown in different environments in Argentina and Spain, were used to establish and validate the relationships between phytosterols and grain oil content. Oil phytosterol concentration decreased in both types of genotypes, lines, and hybrids, when oil content per grain increased. A dilution-like relationship accounted for 82% of the variability in phytosterol concentration among genotypes and environments. Phytosterol concentration rapidly increased with oil contents lower than 11.4 mg per grain. This relationship was observed for total phytosterols and each type of the phytosterols analyzed. With low oil per grain, phytosterol composition varied, with higher proportions of β-sitosterol and Δ 7 -stigmastenol. The relationships established in this work could serve to design breeding and crop management strategies.
