Resumo: |
Starch is a very imp ortant polysaccharide for food processing. It is extracted from different sources and presents very important particular thermal characteristics. The most important temperature for food industry applications is the gelatinization, investigated in this work by techniques of thermal analysis, Differential Scanning Calorimetry (DSC), in various native starches. The thermal behaviour of starch granules was investigated by Thermogravimetry (TG), Differential Thermogravimetry (DTG) and Differential Thermal Analysis (DTA). Also the amylose content was measured for characterization of the native starches. The native starch that presented the lowest gelatinization temperature was the pinhão seed, with peak temperature of 50.8ºC, whereas the lowest amylose content, among non waxy starches, was of banana, with apparent amylose content of 8.1% and total amylose of 9.0%. |
