Talipot starch, a non-conventional starch source with a high yield (76%) from the stem pith of talipot palm (Corypha umbraculifera L.) was subjected to three different thermal treatments (dry-heat, heat-moisture and autoclave treatments) prior to phosphorylation. Upon dual modification of starch with thermal treatments and phosphorylation, the phosphorous content and degree of crosslinking significantly increased (p ≤ 0.05) and was confirmed by the increased peak intensity of P=O and P–O–C stretching vibrations compared to phosphorylated talipot starch in the FT-IR spectrum. The highest degree of crosslinking (0.00418) was observed in the autoclave pretreated phosphorylated talipot starch sample. Thermal pretreatment remarkably changed the granule morphology by creating fissures and grooves. The amylose content and relative crystallinity of all phosphorylated talipot starches significantly decreased (p ≤ 0.05) due to crosslinking by the formation of phosphodiester bonds, reducing the swelling power of dual-modified starches. Among all modified starches, dry-heat pretreated phosphorylated starch gel showed an improved light transmittance value of 28.4%, indicating reduced retrogradation tendency. Pasting and rheological properties represented that the thermal pretreated phosphorylated starch formed stronger gels that improved thermal and shear resistance. Autoclave treatment before phosphorylation of talipot starch showed the highest resistant starch content of 48.08%.
This paper will present the concepts of the EURYDICE project funded by the Erasmus + program. Within this project the focus on renewable energies with the overall goal to enhance employability. The energy generation landscape in South Africa is undergoing a fundamental transition, as the vision of the energy strategy is
to contribute to an affordable energy for all. This vision will be supported by innovative labs and portals which will be developed within this project.
One of the goals is closing the gap between TVET (Technical and Vocational Education and Training Colleges) studies and diploma study by the definition of industrial experience requirements for University of Technology (UoT) diploma students. This leads to an increased preparedness and “studyability” of UoT diploma students. Industrial stakeholders will be integrated into the process. The project will develop an “Industrial Portal” as a working tool.
To increase industry cooperation in post graduate education “OpenLabs” and “MobileLabs” will be developed within the project. It is intended that industry brings industrial problems into the “Labs”, which will then be solved by the students.
