Factors Affecting Starch Conversion to Ethanol in Dry Grind Corn Process
Factors affecting corn starch conversion to ethanol were evaluated to investigate the lack of correlation between ethanol concentration and corn starch content in dry grind corn process. Effect of amylose:amylopectin ratios and resistant starch in corn starch on ethanol concentration was evaluated …

Processing and genetic effects on resistant starch in corn flakes
… effects of processing and genetics on resistant starch content in corn flakes. Cooking (15 psig/121°C, 50 min), drying (100°C, 30 min), tempering (room temperature, 30 min) and toasting (200°C, 60 s) resulted in flakes produced in laboratory that had similar color parameters (L, a and b values) …

Modeling the Fourier transform near infrared spectra of unreacted starch in corn for monitoring applications
… Corn quality changes, in terms of unreacted starch content, in the dry grind process have not been extensively studied, although they impact the efficiency of bioconversion to ethanol and its coproducts. The goal of this research was to monitor changes in unreacted starch content in corn …

Characterization of amylose lipid complexes and their effect on the corn dry grind process
… such as liquefaction temperature, solids content and particle size on formation of amylose lipid complexes (AML) were observed. This helps determine better methods of application in the dry grind industry by providing reasons for decreasing available starch. In the conventional dry grind …

Hydrogen peroxide from photosynthesis: Theory and experiments linking elevated atmospheric CO2 with C3 plant chemical defense
… dynamic light significantly suppressed foliar content of total glucosinolates, the major chemical defense of A. thaliana against insect herbivores. Ultimately, consistent with experimental predictions, caterpillars removed more leaf tissue from A. thaliana grown under elevated CO2 and dynamic …

Heterosis in compositional, physical, and wet-milling characteristics of hybrids from exotic introgressed by adapted inbred lines in corn
… world and the main crop in the United States. Starch is the most abundant component of the corn kernels and the most valuable fraction recovered by wet milling of corn. The amount wet milled from a sample is an indication of the millability or ease with which kernel components are separated. …

Physicochemical properties and molecular structure of kiwifruit starch
… desirable nutritional properties. Kiwifruit is a starch-storing fruit: it accumulates abundant starch by the time commercial harvesting occurs, and most of the starch is gradually hydrolyzed into simple sugars during ripening. Starch plays an important role in kiwifruit development, but basic …

Genotypic variation in Actinidia deliciosa fruit size and carbohydrate content
… correlation between at-harvest dry matter and starch content, and soluble solid concentration and flavour when fruit are eating ripe. This suggests that carbon accumulation strongly influences the development of kiwifruit taste. The overall aim of the present study was to determine what factors …

Effects of water stress and application timing on glyphosate activity in forest trees
… Data on water potential, foliar sugar and starch content, weather, and growth response were gathered for loblolly pine and four of its major competitors on 16 operationally sprayed tracts in Virginia. Glyphosate successfully released loblolly pine on all tracts. Control of white oaks was …

Evaluation of in vitro and in vivo equine microbial population shifts in response to colic conditions
… culture experiments to test the effects of starch dosage and starvation upon equine fecal microflora. Diets were designed containing fructooligosaccharides and mannanoligosaccharides in order to investigate treatment effects on VFA and NH3 concentration, and pH following starvation or starch …

Effects of Grain Sorghum Muffin on Blood Glucose and Insulin Responses in Prediabetic Men
… overlooked. Grain sorghum contains functional starch fractions, which have been widely reported for their potential on blood glucose control and diabetes prevention. A human study with prediabetic men was conducted to investigate the effects of sorghum starch on postprandial blood glucose and …

An investigation into the sapstaining intrinsic properties of selected rubberwood (Hevea brasiliensis) clones
… Tangkah Estate, Johor, Malaysia. The nitrogen contents were determined by the micro- Kjedahl method (Kjeldahl, 1883), the total organic carbon contents were determined by the Walkley-Black procedure (Walkley and Black, 1934), the sugar contents in the selected rubberwood clones were determined …

Effect of irrigation on grain sorghum ethanol yield and sorghum mutants on biomass composition
… decreased as irrigation capacity increased. Starch content increased as irrigation level increased and protein contents decreased as irrigation level increased. Irrigation also had a significant effect on starch properties and bioethanol yield. Sorghum mutants had a significant effect on …

Effect of Functional Starch in Brown Rice and Grain Sorghum on Plasma Glucose and Insulin Responses in Humans
… carbohydrates to control blood glucose levels. Starch is a principle carbohydrate, which influences blood glucose levels, and measuring starch digestibility fractions can help predict the glucose response in the body. The objectives of this study were to investigate the functional starch content …

The modification of nutritional and functional properties of chickpea (Cicer arietinum) by germination.
… and the 48 hr-germinated chickpea, respectively. Starch content decreased 15.5% and soluble sugars increased 20% after only 24 hr of germination. Germination decreased trypsin inhibitor activity by 28%. Chickpea and 24 hr germinated chickpea were used as ingredients in the preparation of several …

What are southern Cape renosterveld geophytes storing in their underground organs?
… Plant species collected were analysed for water content (gig fresh weight), nitrogen percentage (mass spectrometry), phosphorus percentage (dry-ashing extraction method) and starch content (Megazyme Total Starch Assay Kit, which follows an enzymatic procedure). Bulbs (mean = 30.89mm) and tubers …

Characterization of starch accumulation in storage root of Marama (Tylosema Esculentum)
Starch is of substantial industrial significance for food and non-food uses. Plant roots and tubers such as potato and cassava are rich in starch and they are among the sources of starch for food consumption and industrial use. With climatic changes it is important to find crops that can be used as …
