Composition and physical properties of cress (Lepidium sativum L.) and field pennycress (Thlaspi arvense L.) oils

Lepidium sativum L.

Pennycress (Thlaspi arvense L.) is a winter annual oilseed crop with relatively high seed oil content (25-36%-wet basis), which can be planted as cover crop in corn-soybean rotation in the Midwestern U.S., to provide both economic benefits and ecosystem services. Pennycress oil has adequate quality for conversion to renewable jet fuel (RJF); however, the technical feasibility and cost of pennycress supply at the commercial scale have not been evaluated; so, the objective of this study was to evaluate techno-economics of the production, harvest and post-harvest logistics of pennycress as an RJF feedstock. In addition, an uncertainty analysis was performed to address the inherent variability of the parameters used for this evaluation. This study considered the feedstock supply for a biorefinery with RJF production capacity of around 19 million liters per year (i.e., 5 million gallons per year) in Ohio. Technical feasibility included the assessment of resources (land, infrastructure, machineries, fuel, labor, and consumables) for the production (i.e., planting, fertilizer and pesticide applications), harvest and post-harvest logistics (i.e., grain handling, transportation, drying and storage). Economic analyses included estimation of pennycress production and logistics costs. Annual pennycress seed requirement for the selected biorefinery capacity was estimated to be 90–115 thousand t (90% central range - CR), which would require pennycress plantation in 41–63 thousand ha (90% CR) land in corn-soybean rotation. The direct fossil fuel use ratio (i.e., fossil fuel use per liter of RJF produced) for pennycress production and logistics was estimated to be 0.06–0.09 L/L (90% CR). Estimated total cost for the production and logistics was 170–230 $/t (90% CR); and it was identified to be highly sensitive to pennycress seed yield. The outcomes of this research contribute to identifying the bottlenecks and hotspots for establishment of pennycress at the commercial scale in corn-soybean rotation in Ohio and Midwestern U.S.

Seed fatty acid compositions and chemotaxonomy of wild Crambe (Brassicaceae) taxa in Turkey

The physicochemical properties and fatty-acid composition of the oils of the seeds ofLepidium sativum, Eruca sativa, andThlaspi arvense, with oil contents of 23.08%, 33.46%, and 29.18%, respectively, have been determined. The amounts of erucic acid, which is characteristic for Cruciferae, found were 4.71% in the oil ofL. sativum, 37.18% in that ofE. sativa, and 23.04% in that ofTh. arvense.

Oils of three representatives of the family Cruciferae. II

The physicochemical properties of the oils of the seeds of seven plants of the family Cruciferae —Cakile maritima, Sisymbrium altissimum, Sisymbrium Loeselii, Descurainia Sophia, Erysimum cheiranthoides, Brassica amoracioides andCrambe pontica — have been studied and their fatty acid compositions have been determined. The results obtained showed no marked differences from those given in the literature.

The seed oils of some species of the family Cruciferae

The physicochemical properties of the oils of nine species of the genusCrambe have been studied and their fatty-acid compositions have been determined The fatty acids of the oils contain not less than 20% of erucic acid Its highest amounts are found in the oils ofC abyssinica andC pinnatifida — 5701 and 4737%, respectively
