Properties of Sweet Potato Starches from Different Tissue Zones

Abstract: Sweet potato starches prepared from the peel (P), cambium (C), and inner-tissue (IT) were tested for physicochemical properties. The average granule sizes of the IT starches were tended to be larger than those of the P and C starches. Amylose contents of starches from the different tissue zones did not differ significantly. The onset and peak temperatures (To, TP) of the P starches determined by differential scanning calorimetry (DSC) were somewhat high. The C starches were readily digested by the four glucoam… Show more

“…A extração do amido de araruta é feita em caráter doméstico e artesanal, sendo utilizado no preparo de confeitos e panificação 21 . A análise de tamanho de grânulos de amido PÉREZ et al 23 relataram a forma de amidos de araruta, destacando pequena quantidade de grânulos circulares e um predomínio do formato de feijão.…”

“…NODA et al 21 estudaram o tamanho de grânulos de amido de duas cultivares de batata-doce extraídos de diferentes zonas de tecido da raiz. Para o estudo foi utilizado sistema de análise de imagem (Excel-II, Nippon Avionics Co.) conectado a microscópio ótico (Microphot-FXA, Nikon Co.), realizando 1200 determinações de tamanho.…”

“…(Oriental Yeast Co., Ltd., Tokyo, Japan) for 4 h at 40°C according to the modified method of Noda, Takahata, and Nagata (1992). The amount of glucose released during enzyme digestion was estimated by the phenol-sulfuric method (Dubois et al, 1956), and enzyme digestibility was calculated as the percentage of glucose released during incubation with the enzyme to the total amount of sugar in the starch on a weight basis.…”
