A study has been made of the compaction properties of two experimental starches, namely yam starch obtained from Dioscorea rotundata and rice starch obtained from Oryza sativa and the mechanical properties of their tablets, in comparison with those of official corn starch. The influences of the physical and geometric properties of the starch particles on the compression properties of the starch...

Eighty medium-framed yearling crossbreed heifers (357 kg) were used in a 110-d trial to evaluate the influence of dietary protein level (11 vs 14%) on the feeding value of dry rolled (DRC) and steam-flaked corn (SFC). All diets contained 1% urea, cottonseed meal (CSM) was the source of supplemental UIP. Steam flaking corn reduced DMI (9%, P < .10), and increased (P < .01) feed efficiency (14%),...

Currently, there is a search for substances that would be very well tolerated by an organism and which could contribute to the activation of the growth of Bacteroidetes and Actinobacteria strains, with simultaneous inhibition of the growth of Firmicutes. High expectations in this regard are raised with the use of fiber preparations from starch - resistant corn dextrins, branched dextrins, resis...

This study was conducted to evaluate the effects of infrared irradiation for 60, 90, 120 and 150 seconds on starch degradability and chemical compositions of corn grains. Three ruminally fistulated rams were used to measure in sacco degradation. There was a linear increase in DM of irradiated corn grains (P<0.001). Infrared irradiation decreased potentially degradable fraction and constant degr...

Cereal Chem. 76(1):96-99 A corn wet-milling process in which alkali was used was studied as an alternative to the conventional corn wet-milling procedure. In the alkali wet-milling process, corn was soaked in 2% NaOH at 85°C for 5 min and then debranned mechanically to obtain pericarp as a coproduct. Debranned corn was cracked in a roller mill, and the cracked corn was steeped with agitation fo...

Compared with floury or high-moisture corns, dry corn with a greater percentage of vitreous endosperm has been demonstrated to be negatively related to starch digestibility and milk yield of lactating dairy cows. Starch granules in corn are encapsulated by hydrophobic prolamin proteins that are innately insoluble in the rumen environment. Corn prolamin proteins are named zein, and laboratory me...

Methods for processing feedstuffs before analysis can affect analytical results. Effects of drying temperature (corn silage), preservation method (corn grain), and grinding method (corn silage and grain) on starch analysis values were evaluated. Corn silage samples dried at 55 or 105 degrees C and grain samples dried at 55 degrees C were ground to pass the 1-mm screen of an abrasion mill or cut...

The gelatinization properties of starch extracted from corn and waxy corn dried at different temperatures were determined at various water contents and heating rates by differential scanning calorimetry. All gelatinization transition temperatures increased with drying temperature and heating rate. Onset and peak temperatures remained relatively constant, whereas end temperature decreased in the...
