A vast amount of information has accumulated which supports the view that sucrose and starch are end-products of two segregated, yet highly interconnected, gluconeogenic pathways taking place in the cytosol and chloroplast, respectively. However, several lines of experimental evidences indicate that, essentially identical to the case of heterotrophic tissues, starch formation in the photosynthe...

Starch is widely used as an ingredient and significantly contributes to texture, appearance, and overall acceptability of cereal based foods, playing an important role due to its ability to form a matrix, entrapping air bubbles. A detailed characterisation of five gluten-free starches (corn, wheat, rice, tapioca, potato) was performed in this study. In addition, the influence of these starches,...

The objectives of the present study were to characterize good-quality cultivars, identify relationships between local eating preferences and primary compound content, and reveal biofortification potential in tropical root crop species aroids, yams, cassava, and sweet potato. A core sample of about 500 cultivars was assembled to represent the widest agro-morphological diversity. Very high coeffi...

The properties and permeability of aroma compounds in food through the cassava starch films was investigated. Films were prepared by 5% starch and properties of the films were monitored at different concentration of two plasticizers; glycerol and sorbitol. Sorbitol-cassava starch films showed a better transmission rate (water vapor or/and oxygen), and had a higher mechanical properties; tensile...

Primary metabolism is closely linked to plant productivity and quality. Thus, a better understanding of the regulation of primary metabolism by photoreceptors has profound implications for agricultural practices and management. This study aims at identifying the role of light signaling in the regulation of primary metabolism, with an emphasis on starch. We first screened seven cryptochromes and...

Starch is the major energy component of grains. Wheat contains 77% of DM as starch, corn and sorghum contain 72%, and barley and oats contain 57 to 58%. In vitro systems have provided valuable data on kinetic aspects of starch digestion. Molecular biological techniques have provided a clearer picture of the ruminal microbial milieu. Proportions of starch fermented in the rumen can be predicted ...
