Starch is a carbohydrate composed of chain of glucose molecule. Potato, corn, rice are the major sources for starch but they are also used as a food. Our aim was to extract starch from some nonconventional source like taro plant (Colocasia esculenta) and did some physical and chemical modification to enhance the properties of starch. Physical modification method of starch like Osmotic Pressure ...

When glyphosate is applied to glyphosate-resistant (GR) crops, drift to nonglyphosate-resistant (non-GR) crops may cause significant injury and reduce yields. Tools are needed to quantify injury and predict crop losses. In this study, glyphosate drift was simulated by direct application at 12.5% of the recommended label rate to non-GR corn (Zea mays L.) at 3 or 6 weeks after planting (WAP) duri...

Cereal grains represent 30 to 60% of the DM of many companion animal diets. Once incorporated into a diet, the starch component of these grains can provide an excellent source of ME. However, crystallinity and form of starch are variable and can cause incomplete digestion within the gastrointestinal tract. Diets fed in this experiment included one of six high-starch flours as the main source of...

The effect of dietary starch and sucrose on the growth of foci of dysplastic crypts in the colon (FDC) was studied in female Sprague Dawley rats treated twice p.o. with 25 mg/kg of 1,2-dimethylhydrazine (DMH). After DMH administration, the animals were fed high-fat (23% corn oil, w/w)/low-calcium (0.1%, w/w)/low-cellulose (2%, w/w) diets in which carbohydrates were represented by corn starch (s...

Sugary-Brawn2 (su-Bn2) corn endosperm contains higher concentrations of watersoluble polysaccharides than dent corn. Eight multiparous Holstein cows averaging 48 d in milk and 667 kg BW at trial initiation were in a replicated 4 x 4 Latin square design with 28-d periods. Only cows in one square were ruminally cannulated. Treatments were su-Bn2 or dent corn and 45 or 60% of ration DM as alfalfa ...

Crossbred steers (n = 7; 400 kg BW), fitted with T-type cannulas in the duodenum and ileum, were used to examine the effects of processing method, dry-rolled (DR) vs. steam-flaked (SF) sorghum grain, and degree of processing (flake density; FD) of SF corn (SFC) and SF sorghum (SFS) grain on site and extent of DM, starch, and N digestibilities and to measure extent of microbial N flow to the duo...

Cereal Chem. 71(6):532-536 Automated gel-permeation chromatography (GPC), with application pectins with a molecular weight of 107_109, which yielded fragments of of the universal calibration concept, was used to investigate the mechanism 1041 07. Consistent with gravity-flow GPC with dimethyl sulfoxide, sepaof extrusion-induced starch fragmentation in corn. High-amylose and ration indicated tha...

Starch-based adhesive was prepared from corn starch and polyvinyl alcohol (PVA) as raw materials by acid hydrolysis with HCl. The starch was hydrolyzed with different amounts of HCl and characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and thermal gravimetric analysis. The results indicated that different amounts of HCl affected hydrog...

Resistant starch (RS) includes the sum of starch and degradation products of starch that resist small intestinal digestion and enter the colon. This study was planned to examine the effect of resistant starch on hypolipidemic actions, blood glucose, insulin levels and humoral immune responses in healthy overweight subjects. Healthy overweight subjects (over 120% of their ideal body weights) wer...

Background The effect of amylases combined with exogenous carbohydrase and protease in a newly harvested corn diet on starch digestibility, intestine health and cecal microbiota was investigated in broiler chickens. Methods Two hunderd and eighty-eight 5-day-old female chickens were randomly divided into six treatments: a newly harvested corn-soybean meal diet (control); control supplemented ...
