A cheap and biodegradable modifier, cationic starch (CS), was used to turn local soils into effective flocculants for Microcystis aeruginosa (M. aeruginosa) removal. The isoelectric point of soil particles was remarkably increased from pH 0.5 to 11.8 after modification with CS, which made CS modified soil particles positively charged and obtain algal flocculation ability. At the soil concentrat...

These are additives used to convert pharmacologically active compounds into pharmaceutical dosage forms suitable for administration to patients [1]. Although excipients are the non-active ingredients, they are essential in the successful production of acceptable solid dosage forms such as tablets and powders. For example, the lack of filling materials would make it exceedingly challenging, if n...

Amylose extender (ae(-)) starches characteristically have modified starch granule morphology resulting from amylopectin with reduced branch frequency and longer glucan chains in clusters, caused by the loss of activity of the major starch branching enzyme (SBE), which in maize endosperm is SBEIIb. A recent study with ae(-) maize lacking the SBEIIb protein (termed ae1.1 herein) showed that novel...

Reformulation of traditional food systems to introduce new ingredients may change their structure and perceived texture. Interactions between proteins and starch during processing can markedly influence starch gel network structure and rheological profile. The present work aimed to study the effects of soybean protein and the products of enzymatic modification on the pasting and rheological pro...

The effect of starch granule sizes, shapes, composition, and frequency on the dielectric properties (dielectric constant, loss factor, conductivity) native hydrothermally modified starches (potato, corn, rice starch) are investigated in this work. Dielectric determined from 5 Hz to GHz. exhibit lower than GHz due disruption polysaccharide’s molecular arrangement. potato shows highest factor (20...

Article history: Received on: 07/04/2015 Revised on: 22/04/2015 Accepted on: 11/05/2015 Available online: 20/06/2015 Genetically modified organisms (GMOs) and their raw materials used in processed foods should be analyzed and labeled. The aim of our study was to evaluate the present situation of the food products and to determine appropriate DNA isolation method in processed food products. Keep...

The present work describes the construction of a new modified electrode by casting the appropriate mixture of a metallocene, which has been introduced in the experimental part, as a mediator at the surface of glassy carbon (GC) electrode. The proposed modified GC electrode was used for the determination of ascorbic acid (AA) in phosphate buffer (PB) solution (pH = 4.0). When compared to bare GC...

A modified pesta granule was developed for Pseudomonas fluorescens BRG100, a bioherbicidal bacterium for grass weeds, green foxtail (Setaria viridis) and wild oat (Avena fatua). This study reports: i) the effect of formulation water activity (aw) on survival of P. fluorescens BRG100 and, ii) the effect of starch on disintegration and dispersal of a green fluorescent protein transformant of P. f...

Starch without further processing has hydrophilic properties, making it have mechanical and poor dimensional stability, especially in moist or water-rich environments. Thus, efforts to modify starch using chemical processes make hydrophobic been developed. This study aimed characterize chemically modified corn microparticles by acetic acid their application as curcumin carriers. Corn was variou...

Although starch is available and biodegradable, hydrophilicity mechanical properties are still main disadvantages for many applications. In this study, arrowroot starch, a perennial herb found in tropical climates extracted from the tubers of plant was used. The chemically modified by crosslinking with different amounts glutaraldehyde order to overcome disadvantages. crosslinked then prepared a...
