This review covers starch synthesis in the maize endosperm. Starch comprises one of the major glucose polymers in many living organisms. It is critical for plant life since it provides a mechanism to store the vast amounts of fixed carbon arising from photosynthesis. As the major component of many seeds, starch provides the important source of energy transferred from parent to progeny. Animal l...

Amylose can form inclusion complexes with diverse small molecules. Modified starch has different and unique properties compared with its native counterpart. In this study, chemically/enzymatically modified high-amylose maize starches were used to make inclusion complexes with α-naphthol, and the physical properties of complexes and their influences on the rheology of wheat starch were character...

Cotyledons and hulls were prepared from twelve varieties of field beans (Vicia faba L.). Adult cockerels were tube-fed either beans, cotyledons or hull diets containing high or low levels of protein. Metabolizable energy coefficients and starch digestibility coefficients were determined for beans, cotyledons and hull diets. Lipid digestibility coefficients from hull diets were also determined. ...

Standard maize starch was hydrothermally treated by Instantaneous Controlled Pressure Drop (DIC) process at three pressure levels (1, 2 and 3 bar) corresponding to the temperatures of 100, 122 and 135 °C (at 13–27% moisture), respectively. The structural effects of various hydrothermal conditions were examined with differential scanning calorimetry (DSC) and wide-angle X-ray diffraction. In ord...

Two experiments were conducted to test the effects of sources of maize and maize particle sizes on the utilization of phytate P in broiler chicks fed on maize±soyabean meal diets de®cient in P. In Experiment 1, maize from four consignments was ground separately using the same milling facility. Four maize±soyabean diets representing each maize source, and two control diets made of maizestarch±so...

For cost and health reasons, there has been increased interest recently in incorporation starch into imitation cheese formulations where the interaction between the added starch and the protein source (usually casein) has been shown to influence the rheological properties of the imitation cheese. Imitation cheese is widely used as an ingredient in prepared foods such as pizza, lasagne, cordon b...

Cereal Chern. 88(6):589-595 The objective of this research was to investigate the fermentation performance of waxy grain sorghum for ethanol production. Twenty-five waxy grain sorghum varieties were evaluated with a laboratory dry-grind procedure. Total starch and amylose contents were measured following colorimetric procedures. Total starch and amylose contents ranged from 65.4 to 76.3% and fr...

Apparent amylose content (AAC), the key determinant of rice end-use quality attributes, is primarily controlled by the Waxy gene which codes for granule bound starch synthase (GBSS). We examined the combination of sequence variation in the Waxy gene and environmental effects, and their associations with AAC using 171 rice accessions originating from 43 countries. The combination of two single-n...
