Engineering industrial fatty acids in oilseeds

Frontiers in Biology 2013年第3期8卷 323-332页

More than 300 types of modified fatty acids （mFA） are produced in triacylglycerols （TAG） by various plant species, with many of these unusual structures rendering unique physical and chemical properties that are desirable for a variety of bio-based industrial uses. Attempts to produce these mFA in crop species have thus far failed to reach the desired levels of production and highlighted the need to better understand how fatty acids are synthesized and accumulated in seed oils. In this review we discuss how some of the progress made in recent years, such as the improved TAG synthesis model to include acyl editing and new enzymes such as PDCT, may be utilized to achieve the goal of effectively modifying plant oils for industrial uses. Co-expressing several key enzymes may circumvent the bottlenecks for the accumulation of mFA in TAG through efficient removal of mFA from phosphatidylchofine. Other approaches include the prevention of feedback inhibition of fatty acid synthesis and improving primary enzyme activity in host transgenic plants. In addition, genomic approaches are providing unprecedented power to discover more factors that may facilitate engineering mFA in oilseeds. Based on the results of the last 20 years, creating a high mFA accumulating plant will not be done by simply inserting one or two genes; it is necessary to stack genes encoding enzymes with favorable kinetic activity or specificity along with additional complementary transgenes in optimized plant backgrounds to produce industrial fatty acids at desirable levels. Finally, we discuss the potential of Camelina as an industrial oilseed platform.

Review on Volatile Flavor Components of Roasted oilseeds and Their Products

引用

Grain & Oil Science and Technology 2018年第4期1卷 151-156页

作者： LI Cuicui HOU Lixia College of Food Science and Technology Henan University of Technology

Volatile flavor components in foods are the key quality parameters. The researchers conducted in-depth research on sesame oil, peanut oil, rapeseed oil, sunflower oil, sesame paste and peanut butter, etc. However, there is no comprehensive summary about the flavor of roasted oilseeds and their products. The occurrence and the formation mechanisms of the main volatile flavor substances,and the impacts of processing factors are discussed in this review, which may provide references for further research on volatile flavor compounds, identification and evaluation of specific products and development of new products.

Determination of the Place of Implementation of a Biorefinery Based on Logistics Parameters

Journal of Power and Energy Engineering 2022年第5期10卷 22-38页

Airlines and the aviation industry are committed to emission reduction targets. Biokerosene was pointed out as one of the key elements to achieving this goal. The use of oilseeds in the production of biokerosene is interesting due to the great Brazilian experience in the production of biofuels from this raw material. In view of this scenario, this dissertation has as its main objective the definition of the place of implantation of a biorefinery in Brazilian territory that has aviation biokerosene as its main product. For this, data on supply and demand for fossil aviation kerosene in Brazilian regions were collected, an extensive review was carried out in scientific articles on the oleaginous raw materials used for the production of this biofuel, and logistical parameters were selected and used as criteria for that selection. The oilseeds selected for the production of biofuel were macaúba and soybean and the state was chosen for the implementation of the biorefinery was Goiás. Based on logistical parameters, the city of Formosa (GO) was selected to host the biorefinery. The soybean crushers located in Luziania, Anápolis, Ipameri, and Itumbiara were chosen as suppliers of soybean oil and the city of Formosa (GO) as the headquarters for the commercial planting of macaúba. The destination of this fuel will be Petrobrás Distribuidora S.A., an aviation fuel distributor authorized by the ANP based in the city of Brasília (DF).
