Objectives of this study were to (1) determine the starch physicochemical properties of two commercial Tibetan hull-less barley varieties, Beiqing (BQ) and Kangqing (KQ); and (2) understand the relationship between unique properties of the starches, their structures, and impacts of growing conditions. The BQ barleys were grown at a location with lower temperature and less rainfall compared with...

Group A streptococci were found to produce three different desoxyribonucleases, designated here as A, B, and C. These enzymes migrated separately on analysis with starch zone electrophoresis, were immunologically distinct, and showed certain differences in inhibition by citrate and in optimal pH of activity. The relative amount of each enzyme produced was a function of strain variation.

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 ...

Graft polymerizations of vinyl acetate onto granular corn starch were initiated by cobalt-60 irradiation of starch-monomer-water mixtures. and ungrafted poly(vinyl acetate) was separated from the graft copolymer by benzene extraction. Conversions of monomer to polymer were quantitative at a radiation dose of 1.0 IvIrad. However, over half of the polymer was present as ungrafted poly(vinyl aceta...

Starch was isolated from cocoyam (Xanthosoma sagittifolium). It was further modified by acetylation using NaOH and NaHCO3 at room temperature (28±3 oC). The pasting and physicochemical properties of the native and modified starches were then studied. Pasting properties of the alkaline modified cocoyam starches showed higher peak viscosities (245.92-256.96 RVU) compared to low peak viscosity (21...

INTRODUCTION The E 1450 sodium salt of starch octenylsuccinate which exhibits emulsifying properties is used as food additive and is also recommended as yolk replacer in the process of mayonnaise production. Commercial E 1450 preparations reveal excellent functional properties in mayonnaise production. However, sodium salt of starch octenylsuccinate produced in the course of the suspension proc...

Amylose?sodium stearate (SS) complexes (2, 5 and 8%) in heat-moisture treated potato starch (HPS) were evaluated for their physicochemical properties. Based on the DSC thermograms, amylose - SS successfully formed with high thermal stability, indicated by a melt temperature (Tpeak) of ? 112 °C type I ?125 II complexes. Addition 2% resulted single endothermal peak complexes, while 8% led to form...

Abstract Cactus cladodes ( Opuntia ficus-indica ) is a valuable source of dietary fibers. In this study, peeled cladode powder was produced by air drying at 40 °C and characterized for its color, fiber content, rheological behavior. Cladode aqueous suspensions 3% w/w were prepared the effect protein (gelatin, sodium caseinate, whey protein) or salts (NaCl/CaCl 2 on blend’s viscosity investigate...

BACKGROUND In the present investigation, an attempt was made to isolate starch from jackfruit seed powder and utilize it as a superdisintegrant to design fast dissolving tablets of irbesartan. METHODS Starch was isolated from jackfruit seeds via aqueous and alkali extraction processes and evaluated for its physicochemical properties, for phytochemical tests, and for acute toxicity studies. Ir...
