The effect of sprouted wheat wholemeal inclusion in bread recipes on postprandial blood glucose and satiety responses in healthy adults: a randomized trial

Abstract

Sprouted wheat wholemeal was reported to enhance the nutritional and sensory properties of cereal products, but few human studies exist. The effect of blending 50 % sprouted wheat wholemeal in a bread recipe on the postprandial glycemic and satiety responses, and sensory-related sensations was investigated in this randomized crossover human study with 12 healthy participants. Capillary blood samples were collected and glycemic response was determined at 0, 15, 30, 45, 60, 90, 120 min. Satiety visual analogue scales were given every 30 min. While substituting bread wheat flour with sprouted wheat wholemeal significantly increased the α-amylase activity in the dough (p 0.05). Likewise, participant overall acceptability was not adversely affected. Sprouted wheat wholemeal can be used as a functional ingredient in breadmaking, although it did not, in this study, significantly affect digestibility parameters.
