详细描述
Dose response study with 4 dosages of mulberry fruit powdered extract (0.37, 0.75, 1.12 and 1.5 g) added to cooked rice, compared to cooked rice only(reference) on post prandial blood glucose response in healthy Indian adults.
In addition, 1.5 g of mulberry fruit powdered extract was added to instant rice porridge and compared to instant rice porridge only as positive control (replication of previous research.
In total there were 7 test products in the study: 5 active treatments and 2 reference treatments.
