“…The oil content of dried field pennycress seeds was 29.0 wt %, which was in agreement with the range reported previously. − The primary FA detected in FPO was erucic acid (C22:1 13 Z ; 32.8 wt %; Table ), which is typical among members of the Brassicaceae family. ,,,, Other FA of significance included linoleic (C18:2 9 Z ,12 Z ; 22.4 wt %), linolenic (C18:3 9 Z ,12 Z ,15 Z ; 11.8 wt %), oleic (C18:1 9 Z ; 11.1 wt %), gondoic (C20:1 11 Z ; 8.6 wt %), palmitic (C16:0; 3.1 wt %), and nervonic (C24:1 15 Z ; 2.9 wt %) acids. The overall level of saturated FA was low (4.6 wt % total), with palmitic acid comprising the majority of the saturated constituents.…”

“…The CP and PP values of FPO were −25 and −28 °C, respectively, indicating excellent low temperature operability versus SBO as a result of the low saturated FA content . The oxidative stability of crude FPO, as determined by the Rancimat method (EN 14112), was 5.0 h. The specific gravities (25 and 40 °C) and lubricity values (Table ) were in the typical range reported for vegetable oils. , …”

“…Generally considered to be an agricultural pest (weed), field pennycress has potential to serve in a summer/winter rotational cycle with conventional commodity crops (such as corn or soybean), thus not displacing existing agricultural production. Field pennycress is tolerant of fallow lands, requires minimal agricultural inputs (fertilizer, pesticides, water), is not part of the food chain, is compatible with existing farm infrastructure, and has high oil content (20−36 wt %). ,− In addition, each plant may produce up to 15 000 seeds, and fields heavily infested with field pennycress are reported to yield up to 1345 kg of seed/ha . More recent results indicate that the yield from wild populations is in the range of 1120−2240 kg of seed/ha, which equates to around 600−1200 L of oil/ha versus 450 and 420−640 L/ha in the cases of soybean (SBO) and camelina ( C. sativa L.) oils, respectively.…”

Field pennycress (Thlaspi arVense L.) oil is evaluated for the first time as a feedstock for biodiesel production. Biodiesel was obtained in 82 wt % yield by a standard transesterification procedure with methanol and sodium methoxide catalyst at 60 °C and an alcohol to oil molar ratio of 6:1. Acid-catalyzed pretreatment to reduce the acid value of crude field pennycress oil resulted in a yield after methanolysis of 94 wt %. Field pennycress oil had high contents of erucic (13(Z)-docosenoic; 32.8 wt %) and linoleic (9(Z),12(Z)-octadecadienoic; 22.4 wt %) acids with other unsaturated fatty acids comprising most of the remaining fatty acid profile. As a result, the methyl esters (biodiesel) obtained from this oil exhibited a high cetane number of 59.8 and excellent low temperature properties, as evidenced by cloud, pour, and cold filter plugging points of -10, -18, and -17 °C, respectively. The kinematic viscosity and oxidative stability (Rancimat method) of field pennycress oil methyl esters were 5.24 mm 2 /s (40 °C) and 4.4 h (110 °C), respectively. Other fuel properties such as acid value, lubricity, free and total glycerol content, surface tension, as well as sulfur and phosphorus contents were also determined and are discussed in light of biodiesel standards such as ASTM D6751 and EN 14214. Also reported for the first time are cetane numbers of methyl esters of erucic and gondoic (methyl 11(Z)-eicosenoate) acids, which were found to be 74.2 and 73.2, respectively. In summary, field pennycress oil appears to an acceptable feedstock for biodiesel production. † Disclaimer: Product names are necessary to report factually on available data; however, the USDA neither guarantees nor warrants the standard of the product, and the use of the name by USDA implies no approval of the product to the exclusion of others that may also be suitable.
