This trial was conducted to determine the extent of prececal starch digestibility depending on the botanical origin of starch and on diet characteristics (i.e., composition and feeding pattern). The prececal disappearance of six substrates (oats, barley, corn, horse bean, potato, and wheat) was measured in four cannulated horses fed (as-fed basis) 11.8 g/kg BW of a high-fiber (HF) or high-starc...

Microbial modification of starch with Ophiostoma spp. was investigated, with the purpose of developing a novel packaging material for the food or pharmaceutical industries. Various starch sources, such as tapioca, potato, corn, rice and amylopectin were tested as raw materials. The initial screening demonstrated that tapioca and potato starch had better performance for biopolymer production. Th...

Modulation of the malate content of tomato (Solanum lycopersicum) fruit by altering the expression of mitochondrially localized enzymes of the tricarboxylic acid cycle resulted in enhanced transitory starch accumulation and subsequent effects on postharvest fruit physiology. In this study, we assessed whether such a manipulation would similarly affect starch biosynthesis in an organ that displa...

Evidence exists that butyrate inhibits apoptosis of colon crypt cells in vivo so that less tryptophan from cell debris is available for skatole formation by microbes in the pig colon. In this study, potato starch containing a high proportion of resistant starch was fed to test the hypothesis that increased butyrate formation will occur in the colon and contribute to reduced epithelial cell apop...

Tropical gar, Atractosteus tropicus, is a carnivorous fish species from Southern México with high value and acceptance in local markets. Therefore, the present study aims to spare proteins in diets for larviculture of this species. An experiment was performed using three different experimental diets with increasing carbohydrate levels based on potato starch (S) and decreasing protein content (P...

Cereal Chem. 70(2):145-152 Phosphate esters of D-glucose, methyl c-D-glucopyranoside, and on potato starch were confirmed to be the 6and 3-esters. The wheat maltose, as well as the a,,y-limit phosphodextrins from native potato starch phosphate, prepared by heating starch with sodium tripolystarch (degree of substitution [DS] 0.0033) and phosphorylated amylose phosphate under semidry conditions ...

Evaluation of the antimicrobial and antioxidant properties eucalyptus application in production potato starch for meat packing.

Gelatinized starch granules are generally considered to be comprised of sacs or outer membranes of starchy material enclosing a more or less fluid colloidal starch dispersion [see reviews by RADLEY (10)] and KERR (6). NXGEI, (9) and MEYER (8) considered the membrane to be precxistent in the native, ungelatinized granule. ALSBERG (1) and BADENHUIZEN (2, 3) on the other hand, concluded that the m...

The effect of starch granule sizes, shapes, composition, and frequency on the dielectric properties (dielectric constant, loss factor, conductivity) native hydrothermally modified starches (potato, corn, rice starch) are investigated in this work. Dielectric determined from 5 Hz to GHz. exhibit lower than GHz due disruption polysaccharide’s molecular arrangement. potato shows highest factor (20...
