INTRODUCTION In rice breeding programmes large number of grain samples are routinely analysed for amylose content (AC) through a tedious spectrophotometric method that also involves high reagent costs. OBJECTIVE Here, we propose a rapid and economic screening technique for assessment of AC based on the amylose-iodine complex formation in the cut grains of rice, which we refer to as the cut gr...

The SEM of starch from five EAHB cultivars showed a mixture of irregular granule shapes with smooth surfaces. The starches' average diameter size ranged between 16.31 and 21.98 μm. The moisture, protein, and ash content of the starches were: 11.12%-11.84%, 0.1% and 0.23%-0.47% respectively. The amylose content of these starches was between 11% and 13%. The starches peak viscosity ranged between...

Endogenous factors responsible for the textural characteristics of buckwheat products were studied. An analysis with various buckwheat samples showed that there were variations in protein, starch, amylose and amylopectin contents among the various buckwheat flours examined. The protein contents of the buckwheat flours were significantly negatively-correlated to the starch, amylose and amylopect...

The enzyme-dependent conjugates of indomethacin and amylose (Am-IND) were synthesized at room temperature using N,N'-dicyclohexylcarbodiimide (DCC) as a coupling agent and 4-(N,N'-dimethylamino) pyridine (DMAP) as a catalyst. Their structures were characterized by FTIR and (1)H NMR analyses, and the results indicated that the IND residues were conjugated with amylose backbones through ester bon...

BACKGROUND Helicobacter pylori cell surface is composed of lipopolysaccharides (LPSs) yielding structures homologous to mammalian Lewis O-chains blood group antigens. These structures are key mediators in the definition of host-microbial interactions and known to change their expression pattern in response to environmental pressure. AIMS The present work is focused on the identification of ne...

The transgenic rice line (TRS) enriched with amylose and resistant starch (RS) was developed by antisense RNA inhibition of starch-branching enzymes. Cereal starch with high amylose has a great benefit on human health through its resistant starch. In order to evaluate the effect of transgenic rice on rats, the rats were fed diets containing 70% TRS rice flour, its near-isogenic rice flour or th...

The present study compared the effects of three rice cultivars on postprandial glycemic control and appetite. A single-blind, randomized, crossover clinical trial was performed with 18 healthy subjects, nine males and nine females. Three treatments were administered at three separate study visits: commercially available conventional white rice (short grain), specialty high amylose white rice 1 ...

There are several methods in assessing the traits of rice including destructive and non-destructive method. The objective of this study is to evaluate the amylose content (AC) on seven types of rice grain in Malaysia market by using the Near-Infrared (NIR) Spectroscopy. AC is one of the main criteria to determine cooked rice quality. Total of samples are 210, there are including two types of br...
