Abstract EN
Rosin, an abundant raw material from pine trees, was used as a starting material directly for the synthesis of rosin acid starch.
The esterification reaction was catalyzed by lipase (Novozym 435) under mild conditions.
Based on single factor experimentation, the optimal esterification conditions were obtained as follows: rosin acid/anhydrous glucose unit in the molar ratio 2 : 1, reaction time 4 h at 45°C, and 15% of lipase dosage.
The degree of substitution (DS) reaches 0.098.
Product from esterification of cassava starch with rosin acid was confirmed by FTIR spectroscopy and iodine coloration analysis.
Scanning electron microscopy and X-ray diffraction analysis showed that the morphology and crystallinity of the cassava starch were largely destroyed.
Thermogravimetric analysis indicated that thermal stability of rosin acid starch decreased compared with native starch.
