Conteúdo: | Brazilian pine seeds (Araucaria angustifolia) or pinh~ao are popularly consumed in South America as a seasonal food. Pinh~ao of seven accessions were supplied by Brazilian Agricultural Research Corporation (Embrapa/Forestry) germplasm bank. Starch was isolated from those seeds and characterized. Structures and functional properties of starch, including amylose content, molecular weight (Mw) and gyration radius of amylopectin, amylopectin branch chain-length distribution, thermal and pasting properties, and in vitro digestibility were studied. The samples had significant differences on structures and functional properties. The pinh~ao starch consisted of considerable amounts of slowly digestible starch (SDS) and resistant starch (RS). Results obtained from this study are useful for developing new applications for pinh~ao, which is a promising ingredient for the health/nutraceutical food industry.
