The effects of muffins enriched with sour cherry pomace on acceptability, glycemic response, satiety and energy intake: a randomized crossover trial

BACKGROUND: Sour cherry pomace (CP), a by-product obtained during fruit processing, was used to replace wheat flour in a muffin formula. The influence of the most sensory acceptable muffins on glycemic response, appetite sensation, and energy intake during subsequent meal in a randomized crossover trial was studied. RESULTS: It is acceptable to incorporate up to 30% CP into muffin formulas. With CP-treated muffins glucose responses were significantly lower at 30, 45, and 60 min intervals, and the incremental peak glucose was 0.40 and 0.60 mmol L(-1) lower than for plain muffins (PM). The CP-enriched muffins showed an incremental area under the blood glucose response curve values lower than that of PM. 20% CP and 30% CP resulted in improved satiety and induced a lower energy intake at a test meal ingested 3 h later (-13.7%; -15.1%) as compared to PM, respectively. CONCLUSION: CP may be a good functional ingredient for bakery products that assists in managing glucose levels, satiety, and subsequent energy intake in healthy individuals.
