Flours produced by milling fruits dried at diﬀerent conditions were evaluated for colour, starch granules morphology, amylose and sugars content. The drying temperature was positively related to the reducing sugar content and negatively to starch content. The amilose content generally increased with drying temperature and the eﬀect was more evident for the Q. rotundifolia. Results showed that ﬂour colour parameters generally decreased with increased drying temperature. However, the drying temperature does not seem to aﬀect starch morphology. It can also be stated that Q. suber produced darker ﬂours, higher amylose and reducing sugar content, and bigger starch granules. Q. rotundifolia showed a lower level of damaged starch and higher fat and disaccharides content. According to the results, it was possible to conclude that drying temperature exerted marked eﬀects on the properties of acorn ﬂours in both studied species.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Correia, Paula R.</style></author><author><style face="normal" font="default" size="100%">Leitão, António E.</style></author><author><style face="normal" font="default" size="100%">Beirão-da-Costa, Maria L.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effect of drying temperatures on chemical and morphological properties of acorn flours</style></title><secondary-title><style face="normal" font="default" size="100%">International Journal of Food Science &amp; Technology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Acorn (Quercus suber and Quercus rotundifolia)</style></keyword><keyword><style  face="normal" font="default" size="100%">chemical properties</style></keyword><keyword><style  face="normal" font="default" size="100%">drying</style></keyword><keyword><style  face="normal" font="default" size="100%">morphology</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://doi.wiley.com/10.1111/j.1365-2621.2009.01988.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">44</style></volume><pages><style face="normal" font="default" size="100%">1729 - 1736</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Drying curves at diﬀerent temperatures were established for Quercus suber and Quercus rotundifolia fruits.

In investigations of birch and oak suberin made by the author in the fifties, great interest was attached to the publications of Ribas on the chemistry of cork. The present article contains a brief survey of the differences between, and the similarities in, the outer bark of these two wood species, demonstrable on the basis of the investigations mentioned. This comparison, concerned with the chemical properties, is supplemented by a number of scanning electron micrographs of the cork tissue of the two species.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></record></records></xml>
