Single Varietal Dry Bean (Phaseolus vulgaris L.) Pastas: Nutritional Profile and Consumer Acceptability.

Abstract

Dry beans (Phaseolus vulgaris L.) are a nutrient dense food rich in protein, dietary fiber, minerals, and folate. Consumption of dry beans is relatively low in the United States and this may be due in part to the lack of diversity in bean products beyond wholeseeds. Products that incorporate beans in new forms, such as flours, offer the potential to increase dry bean utilization. In this study whole dry beans were milled into flour and used to make gluten free fresh pastas. Six bean varieties each from a different market class (white kidney, navy, otebo, cranberry, dark red kidney and black) were made into pasta. Their consumer appealwas compared to fresh wheat pasta and their nutritional value was compared to fresh wheat pasta and whole boiled beans. The dry bean pastas were nutritionally superior to wheat pasta with higher protein, ash, resistant starch and protein digestibility corrected amino acid score (PDCAAS) as well as lower total starch content. While consumers preferred the flavor, texture and appearance of the wheat pasta to the dry bean pasta, 36% of participants said they would definitely or probably purchase the dry bean pastas from the light colored beans. There was some loss of nutritional value of bean pasta vs. whole boiled beans but this can mostly be attributed to the bean pasta being 90% bean. These results suggest that single variety fresh dry bean pastas have commercial potential in the U.S. as healthy gluten free pasta options.
