Amylose content of rice marketed in Portugal
Correia, Paula; Santos, Tania; Lemos, Diogo; Brites, Carla; Guiné, RaquelAmylose content is considered to be the most important parameter of cooking quality in rice. Presently, rice cultivars are categorized according to amylose content into three groups: low, medium and high amylose content cultivars. The specific objective of this work is to evaluate the grain amylose content of 77 cultivars, which cover Índica and Japónica subspecies, and different types of commercial rice like, ...
Contribution for the characterization of aromatic rice
Santos, Tânia; Lemos, Diogo; Brites, Carla; Guiné, Raquel; Correia, PaulaRice is consumed mainly as whole grain, and quality considerations are much more important than for any other food crop. Rice grain quality preference varies from country to country and among regions. Nowadays, aromatic rice varieties are playing a vital role in global rice trading, and also in Portugal. Five types of aromatic rice were collected and analysed for biometry characteristics, amylose content and ge...
Contribution for the characterisation of Carolino rice cultivars
Santos, Tania; Lemos, Diogo; Brites, Carla; Guiné, Raquel; Correia, PaulaRice is consumed mainly as whole grain, and quality considerations are much more important than for any other food crop. Rice grain quality preference varies from country to country and among regions. Most of the rice produced in Portugal is of the Carolino type, botanically classified as Oryza sativa ssp. Japonica. Nowadays, this rice is playing a vital role in Portuguese rice trading. Thir...
Effect of wheat puroindoline alleles on functional properties of starch
Brites, Carla Moita; Santos, Carla Alexandra Lourenço; Bagulho, Ana Sofia; Beirão-da-Costa, Maria LuisaPuroindoline a and b (Pina, Pinb) form the molecular basis of bread wheat grain hardness. Varieties with a softer endosperm and a wild genotype, in which both Pina and Pinb were present, seemed to produce less damaged starch Xour than hard varieties, where Pin mutations occurred and changed the starch rheological properties. The functional property of starch samples extracted from wheat varieties with diVerent ...
