Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential. A colloidal particle exerts so-called Brownian motion due to thermal co...

Salmonella Typhimurium (S. Typhi) and Escherichia coli (E. coli) have been responsible for an increasing number of outbreaks linked to fresh produce, such as baby spinach leaves, in the last two decades. More recently, antimicrobial biodegradable packaging systems have been attracting much attention in the food packaging industry as eco-friendly alternatives to conventional plastic packaging. T...

Cereal Chem. 78(4):442–446 In this study, 3% aqueous high-amylose maize starch (Hylon VII) dispersions were heated to temperatures of 140–165°C. The onset and rate of gel formation was observed using a small-strain oscillation rheometer as a function of temperature from 90 to 25°C. The gel formation clearly began earlier in high-amylose starch paste preheated at lower temperatures, but the rate...

A series of hydroxypropylated starch (HPS) that can be dissolved in water at 60–65 °C was obtained via two-step method system from corn starch. The structure and property the HPS its gelatinization temperature were characterized by Fourier transform infrared spectrometer, nuclear magnetic resonance spectroscopy (1H NMR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), electron...

Hydroxypropyl starch was synthesized by modified sago starch with hydroxypropylation reaction. Hydroxypropyl starch nanoparticles with mean particle sizes of 110 nm are obtained by controlled precipitation through the drop-wise addition of dissolved hydroxypropyl starch solution into excess absolute ethanol. Piperine was loaded onto hydroxypropyl starch nanoparticles and native starch nanoparti...

Low density polyethylene (LDPE) is used for packaging and other industrial application a significant source of environmental pollution. The present study was aimed at testing the ability bacterial strains identified as Bacillus cereus Pseudomonas aeruginosa to degrade LDPE. These were isolated from soil samples collected dump site. All isolates screened their synthetic produced weight loss perc...
