- How long does it take to convert crambe seed to erucic acid?
- Nuclear magnetic resonance analysis showed that the prepared erucic acid had an excellent pattern of correlation with a commercial standard. The time needed to convert 1 kg of crambe seed to erucic acid is about 48 h. Crystal filtration and drying stages under the current process conditions require 30% of the overall time.
- Does erucic acid cross with rapeseed?
- Erucic acid is currently mainly derived from high erucic acid rapeseed (HEARs with ca. 50% of 22 : 1 in its seed oil). However, HEARs cross readily with the existing food oil rapeseed, and its seeds can be inadvertently mixed with food qualities, thus complicating the commercial production and supply of HEARs.
- How much erucic acid is in seed oil?
- The average, maximum (max) and minimum (min) levels of erucic acid (22 : 1) content in the seed oil from different generations of transgenic crambe lines with LdLPAAT, BnFAE1 and FAD2-RNAi genes T1, T2, T3 and T4 are generations of transgenic lines.
- Is erucic acid a major feedstock for the oleochemical industry?
- Erucic acid (22 : 1) is a major feedstock for the oleochemical industry. In this study, a gene stacking strategy was employed to develop transgenic Crambe abyssinica lines with increased 22 : 1 levels.
- What is erucic acid derived from?
- Erucic acid (22 : 1) and its derivatives, mainly erucamide, are important industrial feedstocks in manufacturing plastics, nylon13-13 and high temperature lubricants ( Leonard, 1994; Piazza and Foglia, 2001; Sonntag, 1991 ). Erucic acid is currently mainly derived from high erucic acid rapeseed (HEARs with ca. 50% of 22 : 1 in its seed oil).
- What is the difference between erucic rapeseed and wild-type Crambe?
- Unlike high erucic rapeseed, the wild-type crambe contains 22 : 1 in the seed phosphatidylcholine and in the sn-2 position of triacylglycerols (5% and 8%, respectively). The transgenic line with high 22 : 1 had decreased 22 : 1 level in phosphatidylcholine, and this was negatively correlated with the 22 : 1 level at the sn-2 position of TAG.
