Botanical Research and Applications

Ariá (Goeppertia allouia) is a tuber from the arrowroot's family widely found in the Brazilian Amazon. The tuber has a flavor similar to corn, besides high retrogradation when cooked, differing from other commercial starches. To enhance its added value, the Ariá starch was extracted to evaluate its potential as a food ingredient. The Ariá starch was compared to the commercially available corn and potato starches regarding their physicochemical, thermal, structural, and rheological properties based on the Duncan's test (p-value <0.05). The Ariá starch presented high amylose content (~38% w/w). Furthermore, the X-ray diffraction pattern confirmed its Type-C crystalline structure. The rheological properties showed that the starch gels presented high hardness and retrogradation as other studied starches. Ariá has great potential as a source of starch with low digestibility, increasing the satiety of food products.
