Colloidal properties of sugar particle dispersions in food oils with relevance to chocolate processing
… polyglycerol polyricinoleate (PGPR) or monoolein, were used to alter the interactions between the hydrophilic sugar particles. In a dispersion of 70 wt% sugar and 0.3% of lecithin, approximately 30-40% of the emulsifier present was found to be adsorbed at the surface of the …

EVALUATION OF SEED TREATMENTS ON THE NODULE COMPETENCY OF SOYBEAN INOCULANTS
Soybean has a strong demand for nitrogen that can be acquired from atmosphere for vegetative growth and seed production through the symbiosis with the soil bacterium Bradyrhizobium japonicum (B. japonicum). However, the native soil bradyrhizobia may be ineffective in nitrogen fixation and the …
