In the conventional maize wet-milling process, a maize kernel is separated into its individual components. Starch (which constitutes 60–70% of the maize kernel) is the prime product. Other components of the maize kernel, which includes germ (oil), protein and the fiber, are recovered as coproducts. Presently, maize fiber is mixed with heavy steepwater and sometimes with germ meal to produce mai...

• Pozole samples showed the amylose-lipid complex dissociation enthalpies as lard concentration rose. Amylose-lipid increased pasting temperature and reduced viscosity profile of pozole samples. XRD patterns new peaks 13 20 ° due to a crystalline lamellar growing at 051 040 directions. RS in proportionally rose complexing. One most traditional foods Mexico is (a soup maize grains with pork). Ma...

Maize starches from three wx-containing genotypes (wx, du wx, and ae wx) in two inbred lines (W64A and IaS125) were examined to evaluate the effect of mutant genotype on amylopectin fine structure and thermal behavior of starch granules. The amylopectin chain length distribution and A:B chain ratio were investigated by enzymatic treatments followed by high-performance size-exclusion chromatogra...

In addition to the exclusively granule-bound starch synthase GBSSI, starch granules also bind significant proportions of other starch biosynthetic enzymes, particularly starch synthases (SS) SSI and SSIIa, and starch branching enzyme (BE) BEIIb. Whether this association is a functional aspect of starch biosynthesis, or results from non-specific entrapment during amylopectin crystallization, is ...

The digestibility of the starch in plant foods is highly variable, and is dependent on a number of factors, including the physical structure of both the starch and the food matrix. An in vitro technique has been developed to categorize starch in plant foods according to its likely rate and extent of digestion in the human small intestine. The in vitro method provides values for rapidly digestib...

Essentially all plants store starch in their leaves during the day and break it down the following night. This transitory starch accumulation acts as an overflow mechanism when the sucrose synthesis capacity is limiting, and transitory starch also acts as a carbon store to provide sugar at night. Transitory starch breakdown can occur by either of two pathways; significant progress has been made...

Fractional rate of degradation (kd) of fermentable nutrients in the rumen is an important parameter in modern feed evaluation systems based on mechanistic models. Estimates of kd for starch was obtained on 19 starch sources originating from barley, wheat, oat, maize and peas and treated in different ways both chemically and physically. The starch sources were fed in mixed diets together with gr...

To have all-year-round available feedstock, whole-crop maize is harvested premature, when it still contains enough moisture for the anaerobic ensiling process. Silage preparation is a well-known procedure for preserving plant material. At first, this method was applied to obtain high-quality animal feed. However, it was found that such ensiled crops are very suitable for bioenergy production. M...

1. Male Sprague-Dawley rats were fed on either a purified, fibre-free diet or a diet in which half the maize starch was replaced with uncooked amylomaize or potato starch (equivalent to 100 or 200 g amylase-resistant starch (ARS)/kg diet respectively). Changes in short-chain fatty acids (SCFA), pH, ammonia and a number of bacterial variables in caecal contents were then assessed. 2. Both ARS su...

The lungs of eight drug addicts dying as a consequence of their habit have been examined. All showed the presence of small amounts of talc emboli and five the presence of starch emboli. Talc was invariably associated with a marked foreign body reaction which was insignificant in association with starch. Animal experiments showed very rapid (90% in 24 hours) removal of maize starch emboli; such ...
