Abstract:

Starch nutritional fractions as well as thermal properties and other analysis are essential for food and industrial application. Cassava bagasse is an important agro-industrial residue and its starch content was evaluated using two alternative methods. Thermal characterization and microscopy analyses helped to understand how hydrolysis digests starchy fraction of cassava bagasse. The melting point of cassava starch occurred at 169.2ºC. Regarding TG analyses, after moisture content, there were observed two main mass losses for all samples. Results suggest hydrolysis carried out using enzyme is

Abstract:

An innovative methodology based on non-destructive observation by using harmonic generation microscopy is proposed for detection and location of starch granules and oil in a fried starchy matrix and topography analysis of food products. Specific fluorescent probes were used to label the main biochemical components of the starchy fried matrix, namely starch and oil. Fluorescence of starch and oil respectively stained with Safranin O and Nile red was observed from non-linear microscopy. By using sequential scanning and specific emission filters, it was possible to merge fluorescence and harmonic

A low field magnetic resonance technique was used to analyze the water mobility character about wheat starch and its resistant starch (RS) suspensions at different water activity. RS was obtained from wheat starch by high temperature and high pressure method. Scanning electron microscopy(SEM), X-ray diffraction analysis and differential scanning calorimetry (DSC) analysis were used to evaluate the variation between the starch and RS after treatment. Compared with the original starch, it was suggested that the capacity of combining water of RS was stronger than starche from the NMR relaxation p

Abstract:

In plants, starch is synthesized in leaves during the day-time from fixed carbon through photosynthesis and is mobilized at night to support continued respiration, sucrose export, and growth in the dark. The main crops where starch is biosynthesized and stored are corn, rice, wheat, and potatoes, and they are mainly used as food resources for humankind. There are many genes that are involved in starch biosynthesis from cytosol to storage organs in plants. ADP-glucose, UDP- glucose, and glucose-6-phosphate are synthesized catalyzed by UDP-invertase, AGPase, hexokinase, and P- hexose-isomerase i

The botanical origin of starch is of importance in industrial applications and food processing because it may influence the properties of the final product.

The absorbance of the starch-triiodide complex was measured for wheat, potato, corn, rye, barley, rice, tapioca and unknown origin starch, and within the different cultivars.

Abstract:

Starch is one of the most demanded renewable feedstock in the world. The degree of phosphorylation of native potato (Solanum tuberosum L.) starch is a practically important quantitative trait, significantly influencing its physical and chemical properties. In this study, we evaluated the genetic diversity of the population of potato varieties and quantified phosphorus content in potato tuber starch harvested in 2017, 2018, and 2019. With the statistical methods, the most promising varieties for the next generation of breeding were identified for the first time. Genotyping and chemotyping data

Abstract:

Chestnuts are popular edible nuts that are rich in starch. In order to enhance the transcriptomic resources and further understand starch and sucrose metabolism in maturing chestnuts, a comparative transcriptomic study of Chinese chestnut kernels was conducted at three ripening stages (70, 82, and 94 DAF). At 82 and 94 days after flowering (DAF), starch continued to accumulate, and the amylopectin/amylose ratio increased. Transcriptomic profiling of kernels at 70 (stage I), 82 (stage II), and 94 DAF (stage III) indicated that soluble starch synthase and α-1,4-glucan branching enzyme genes are

The sugary-2 mutation in maize (Zea mays L.) is a result of the loss of catalytic activity of the endosperm-specific SS (starch synthase) IIa isoform causing major alterations to amylopectin architecture. The present study reports a biochemical and molecular analysis of an allelic variant of the sugary-2 mutation expressing a catalytically inactive form of SSIIa and sheds new light on its central role in protein–protein interactions and determination of the starch granule proteome. The mutant SSIIa revealed two amino acid substitutions, one being a highly conserved residue (Gly522→Arg) respons

The processability of conductive polymers still represents a challenge. The use of potato starch as a steric stabilizer for the preparation of stable dispersions of polyaniline (emeraldine base, EB) is described in this paper. Biocomposites are obtained by oxidative polymerization of aniline in aqueous solutions containing different ratios of aniline and starch (% w/w). PANI-EB/Starch biocomposites are subjected to structural analysis (UV-Visible, RAMAN, ATR, XRD), thermal analysis (TGA, DSC), morphological analysis (SEM, Laser Granulometry), and electrochemical analysis using cyclic voltammet

Abstract:

ABSTRACT An early step in the utilization of starch by Bacteroides thetaiotaomicron is the binding of starch to the bacterial surface. Four starch-associated outer membrane proteins of B. thetaiotaomicron that have no starch-degrading activity have been identified. Two of these, SusC and SusD, have been shown by genetic analysis to be required for starch binding. In this study, we provide the first biochemical evidence that these two proteins interact physically with each other. Both formaldehyde cross-linking and nondenaturing gel electrophoresis experiments showed that SusC and SusD interact

Abstract:

Carbohydrates in dairy concentrate originate from cereals containing high starch and a variety of by-products with high levels of fibre. Selection is based on unit cost and chemical analysis. Comparisons between starchy and fibrous sources were made at a single level of crude protein (CP) by Thomas et al (1986) and Sutton et al (1987). Voluntary intake of forage increased and yields of fat and protein were similar when fibre replaced starch. The objective of this trial was to extend the range of comparisons by establishing the effects of three types of carbohydrate at four levels of crude prot
