INTRODUÇÃO: O amido encontra-se entre os hidratos de carbono mais abundantes na nossa alimentação, desempenhando um papel importante ao nível das respostas glicémicas suscitadas pelas nossas refeições. Certas características dos alimentos podem influenciar a atividade de enzimas-chave do processo digestivo do amido e, deste modo, influenciar também...
L’impression 3D par extrusion présente un fort potentiel pour la production automatisée d’aliments de propriétés nutritionnelles et organoleptiques précisément contrôlées. Pour construire l’objet comestible, le matériau alimentaire est extrudé en une couche de matière continue ne se déformant pas sous sa masse après déposition ni sous la masse des ...
This research aimed to develop biofilms based on starch isolated from chachafruto (Erythrina edulis) grown in Colombia. The physicochemical, functional, and morphometric properties of chachafruto starch were characterized. Edible biofilms were developed using chachafruto starch, glycerol, oil, and Tween 80. The films were characterized in terms of ...
Les interactions entre polysaccharides et lipides forment aujourd'hui un vaste domaine d'étude, présentant notamment un intérêt particulier pour les industries alimentaires et pharmaceutiques. Nous savons que l'amylose, un polysaccharide composé de résidus glucose branchés en [apha 1→4] essentiellement linéaire, peut encapsuler de petites molécules...
Starch plays a central role during fruit development and ripening. Its degradation provides energy and sugars in ripening fruits whereas its accumulation responds to environmental stresses, which suggests a buffering role. Knowledge of starch metabolism in leaves has dramatically improved, mostly through the characterization of Arabidopsis mutants ...
Roots and Tuber crops plays an eminent, countless and complex part in feeding the world. These crops have the potential to eradicate poverty and improve food security. Starch is the principal component of roots and tuber crops. The significance of starch as a raw material in both food and non-food industries are increasing. In present study efficie...
La ramification est une variable du rendement des cultures dont la sensibilité aux conditions environnementales et dont le contrôle revêt un intérêt agronomique majeur. Nous nous intéressons ici à la régulation du débourrement des bourgeons axillaires par l’intensité lumineuse chez le rosier buisson. Plusieurs études ont souligné la sensibilité de ...
Tigernut tubers (Cyperus esculentus) are used for the production of vegetable milk, commonly known as “Horchata de chufa” in Spain. The presence of starch in the tuber limits the yield of the milk, since this carbohydrate gelatinizes during the pasteurization of the milk and leads to the considerable solidification of this drink. The present work a...
There is little known about the function of rice hexokinases (HXKs) in planta. We characterized hxk5-1, a Tos17 mutant of OsHXK5 that is up-regulated in maturing pollen, a stage when starch accumulates. Progeny analysis of self-pollinated heterozygotes of hxk5-1 and reciprocal crosses between the wild-type and heterozygotes revealed that loss of HX...
BACKGROUND: The presence of insoluble calcium oxalate druse crystals (CaOx) in sweet potato (Ipomoea batatas) can negatively affect its nutritional quality. Photosynthesis, starch, and protein composition are linked with oxalate synthesis and tuber quality under water scarcity. Our main objective was the oxalate quantitation of sweet potato tubers ...
