Abstract
|
|
|
|
Saengshik beverage products were developed to improve the convenience in consumption, and thereby to expand the Saengshik market. Beverages were prepared from 3 commercial Saengshik products (ES, BS, SS) by mixing with water using a high shear blender. The physicochemical and sensory properties of the Saengshik beverage product were compared. The most acceptable beverage product was made of BS at 7.7% (w/w) level. The apparent viscosity of the beverages increased as the Saengshik levels increased. The beverages at lower Saengshik levels showed dilatant fluid characteristics, while they were Newtonian and pseudoplastic fluids at middle and high Saengshik levels, respectively. The beverage products also showed rheopectic type time-dependency at middle (5.7-9.7%) Saengshik levels, while they were time independent at low and high levels.
