Starches were purified from barley flours milled from Waxbar, Glacier, high-amylose Glacier (HAG) and hull-less high-amylose Glacier (HHAG) cultivars. Wheat starch, maize amylopectin, maize amylose, and normal maize starch were used for comparative controls. Starches were either boiled or moisture-autoclaved (3 or 12 times) with subsequent cooling overnight, after which enzyme-resistant starch ...

Cereal Chern. 84(4):415-422 Starch granules undergo structural and morphological changes during food processing unit operations as they interact with other food ingredients. This study was conducted to isolate and characterize starch granules from com masa. A proteolytic enzyme, thermolysin, was effective in separating and isolating starch granules from endosperm proteins present in masa. The e...

Cereal Chern. 88(6):589-595 The objective of this research was to investigate the fermentation performance of waxy grain sorghum for ethanol production. Twenty-five waxy grain sorghum varieties were evaluated with a laboratory dry-grind procedure. Total starch and amylose contents were measured following colorimetric procedures. Total starch and amylose contents ranged from 65.4 to 76.3% and fr...

Background: Pompe disease is a progressive metabolic neuromuscular disorder resulting from deficiency of lysosomal acid -glucosidase (GAA). Infantile-onset Pompe disease is characterized by cardiomyopathy, respiratory and skeletal muscle weakness, and early death. The safety and efficacy of recombinant human (rh) GAA were evaluated in 18 patients with rapidly progressing infantile-onset Pompe d...

In an effort to develop an inexpensive alternative to vapor-heat insect disinfestation of ‘Kensington’ mango (Mangifera indica Linn.), the effect of postharvest hot water treatments (HWT) on fruit quality was determined. Fruit were given 46C HWT for 30 minutes at a fruit core temperature of 45C either 24 hours after harvest or after various conditioning treatments of 4 to 24 hours at 39 ± 1C in...

Cereal Chem. 84(6):533-539 One Oat cultivar grown in Idaho (three field sites) was pin-milled and separated by sieving to investigate whether starch from oat bran differs from the remainder of kernel. Ground oat particles were classified into three sieve fractions: 300-850 pm, 150-300 om and <150 Om). Il-Glucan content in sieve fractions was analyzed and starch was extracted from kernels withou...

A key objective of forage preservation as hay or Extensive degradation of protein during fermentation of high-prosilage is to minimize quality and dry matter (DM) tein crops reduces efficiency of dietary N utilization in ruminants. losses. A major disadvantage to preserving forage as Evidence suggests that enhanced levels of fermentable carbohydrates hay is the risk of exposure to adverse weath...

Celiac disease, also called celiac sprue, is an auto-immune disease in which a reaction to a sequence of amino acids in prolamins, especially gliadin of wheat gluten, causes deformation of absorptive villae of the small intestine. As a result, nutrients are poorly absorbed. Children fail to thrive and, in the adult-onset form of the disease, intense intestinal distress is a characteristic, with...
