Pulses are high in protein and dietary fibre but their long preparation time can be a barrier to consumption. We have developed PulseON® – novel pre-cooked cell powders that can be prepared from various legumes and used as functional food ingredients. Techno-functional characteristics and starch digestibility of powders prepared from seven different pulses were compared to flours from the same source. All PulseON® powders consisted of intact plant cells with low starch digestibility (<40% starch digested at 90 min) compared with cooked pulse flours (>80% starch digested within 30 min) and had a higher water holding capacity and swelling power than their flour counterpart. A glycaemic study in healthy human subjects demonstrated that the chickpea PulseON® had a low-medium glycaemic index. Overall, PulseON® powders provide superior starch resistance to normal pulse flours and their glycaemic properties show promise in functional food applications to benefit cardiometabolic health.
