Esterification of starch was carried out to expand the usefulness of starch for a myriad of industrial applications. Lipase B from Candida antarctica, immobilized on macroporous acrylic resin (Novozym 435), was used for starch esterification in two reaction systems: micro-solvent system and solvent-free system. The esterification of corn starch with palmitic acid in the solvent-free system and ...

A method to refine corn produces highly pure corn protein isolate (CPI) and intact granular starches (CPI starch). The CPI starch is superior to other commercial starches because of its intact membrane. This paper reports on the effectiveness of the CPI starch in laundering applications by comparison with a commercial starch and polyvinyl alcohol (PVA). Influence of the different starch materia...

OBJECTIVE This trial was performed to examine the effects of ruminally degradable starch (RDS) levels in total mixed ration (TMR) with low corn-based starch on the milk production, whole-tract nutrient digestibility and nitrogen balance in dairy cows. METHODS Eight multiparous Holstein cows (body weight [BW]: 717±63 kg; days in milk [DIM]: 169±29) were assigned to a crossover design with two ...

This research was conducted to determine the effect of corn genetics and cutting height on the composition and nutritive characteristics of corn silage. An in situ study involving eight commercially available corn hybrids indicated main effects and interactions (P < 0.01) of hybrid and cutting height on NDF, ADF, and starch content and on in situ DM and NDF degradablility. Four ruminally cannul...

This research paper deals with the synthesis and characterization of corn starch based composites using resorcinolformaldehyde as cross linker. Acid, base and moisture resistance studies of the composites were also done. Moreover, biodegradation studies of the composites were also done using composting method and the different stages of the biodegradation were evaluated using scanning electron ...

Rumen characteristics and digestive kinetics of brown midrib corn silage were evaluated with five late-lactation (221 DIM +/- 20 d) multiparous cows fitted with ruminal and duodenal cannula. Dietary treatments were applied by using a single reversal design with two 21-d periods where either brown midrib (BM3) or isogenic (ISO) corn silage were included in a total mixed ration formulated to be 4...

Most pulse (nonoilseed legume) seed flours can be fractionated rapidly and economically by air classification into protein and starch concentrates. The nutritional value of air-classified field pea and faba bean concentrates requires characterization to assess the feeding opportunity for pigs. Thus, the objectives were to characterize the apparent total tract digestibility (ATTD) of DM, OM, ene...

A starch formulation of Bacillus thuringiensis Berliner is being developed as a component in a pest management system to control Ostrinia nubi/alis (Hubner). Palatability is one property of starch formulations which must be investigated; this study was done to identify materials that will cause O. nubi/alis larvae to feed readily on starch granules. A two-choice behavioral bioassay was develope...

Glucose and high fructose syrup (HFS) are made extensively from corn starch and the high cost of production demands the lookout for alternative starches as raw material. The present study was to compare the potential of tuber starches such as arrowroot, cassava, Curcuma, Dioscorea, sweet potato and Xanthosoma with corn starch for HFS production. The process consisted of liquefaction followed by...

 Carbohydrates, NDF and NFC, comprise about 70% of DM in diets for lactating cows.  While diets containing 21% forage-NDF are common, depending on forage availability, price and quality, diets can be found within a normal range of 16% 24% forage-NDF (DM basis).  Maximum NFC guidelines are positively related to forage-NDF content in diets for lactating cows.  Starch is the major component of...
