Wageningen University Chair of Valorisation of Plant Production Chains (WU-VPP) is a multidisciplinary research group within the Agrotechnology and Food Science Group (AFSG) performing scientific and applied research aiming at the development of economically and environmentally sound (bio)chemical, enzymatic and biological conversion and fermentation processes. These processes are based on plant raw materials and should substitute fossil resources of bulk chemicals, transportation fuels and animal feed.
Key components of the research are the definition of measures to reduce industrial energy consumption on a global scale, to fully exploit available and as yet uncovered cheap resources of agricultural (waste) streams, and to decrease CO2 emissions and pollution.
Speaker Profile
Since March 2007, Dianika Lestari has been registered as PhD student at Wageningen University Chair of Valorisation of Plant Production Chains (WU-VPP), Wageningen University & Research Centre, The Netherlands. Funded by KNAW (Royal Netherlands Academy of Art and Sciences), her research is focused on non food/ technical application of Jatropha curcas protein. Based on her background on chemical engineering, her objectives are to make high quality products from Jatropha protein at low cost.
Overview of Presentation
Jatropha seed cake that remains after oil pressing contains valuable products. The protein can be used for technical applications, such as coatings, adhesives, and bioplastics. For industrial use of Jatropha protein, a commercial and feasible extraction process has to be developed that result in high protein recovery. Isolated protein must have high purity and good functional properties.
The objective of this research is to improve protein recovery of extraction at room temperature by multi-stage counter-current extraction. At room temperature, a four-stage counter-current extraction at solvent to solid ratio of 4 g/g by using 0.055 M NaOH gave about 70% protein recovery in the extract and it did not change protein molecular weight distributions.
Study on Jatropha protein film-forming properties showed promising results and indicated that Jatropha seed protein may be a potential material for technical applications.
