Two key feed processing parameters, conditioning temperature and time, were altered to determine their effects on concentration of gelatinized starch and vitamin retention in a pelleted finishing swine diet. Diet formulation (corn–soybean meal based with 30% distillers dried grains with solubles) was held constant. Treatments were arranged in a 2 × 3 factorial design plus a control with 2 condi...

The processing methods for mung bean starch noodles were used to form “starch pasta” from various isolated wheat starches. The objective of this research was to evaluate the changes in the surface and internal structure of pasta and “starch pasta” made from various flours and wheat starch before and after cooking. Cooked “starch pasta” revealed a honeycomb-like internal structure similar to coo...

Current injectable calcium phosphate bone cements (CPC) encounter the problems of low strength, high brittleness, and low cohesion in aqueous environment, which greatly hinder their clinical applications for loading-bearing bone substitution and minimally invasive orthopedic surgeries. Here, a strategy of using gelatinized starches to reinforce injectable CPC was investigated. Four types of sta...

A series of well-characterized starch-g-polyacrylonitrile (PAN) graft copolymers was prepared from corn starch which had been heated in water at temperatures up to 94°C to vary the extent of starch granule swelling and disruption. Graft polymerization onto gelatinized starch gave less frequent grafting of higher molecular weight PAN than comparable graft polymerizations onto ungelatinized starc...

An enzymatic method based on hydrolysis of starch by amyloglucosidase and measurement of d-glucose released by glucose oxidase-peroxidase was developed to measure both gelatinized starch and hydrolyzable starch in situ of dried starchy products. Efforts focused on the development of sample handling steps (particle size reduction of dry samples followed by a unique mechanical resolubilization st...

The soaked and nonsoaked rice grains were cooked by the excess water method and the steamer method, and subjected to Ranghino's test, X-ray diffraction, and microscopic observation. The starch granules in the nonsoaked rice were gelatinized at the same time as the grains became translucent during cooking. However, when the grains of medium amylose varieties and waxy rice were presoaked, the sta...

Polylactic acid (PLA)/starch fibers were produced by twin screw extrusion of PLA with granular or gelatinized starch/glycerol followed by drawing through a set of winders with an intermediate oven. At 30% starch, fibers drawn 2–5x were highly flexible (elongation 20–100%) while undrawn filaments were brittle (elongation 2–9%). Tensile strength and moduli increased with increasing draw ratio but...

In this study, modified starch was used as a fat replacer in the milk. The fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. Modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. Viscosity, total solid, fat content, titr...

wheat starch is the most common type of starch in iran as well as many other parts of the world with enormous applications in food and non-food products. to improve its physicochemical properties or create new functionalities, starch can be modified by changing its molecular structure. amongst different methods for starch modification, physical methods have received more attention recently. pre...

The aim of this study is to evaluate the adhesion ability of okra gum, which is gaining popularity as a tablet binder. For this purpose, gum was extracted from okra pods, and the binding strength of different concentrations (1%, 3%, and 5%) was determined quantitatively. Additionally, naproxen sodium tablets were prepared by using okra gum as a binder and were evaluated for their properties inc...
