Contact Efficacy of Two Amorphous Silica Powders against the Red Flour Beetle, (Herbst) (Coleoptera: Tenebrionidae).

The contact efficacy of two amorphous silica powders 1 and 2 procured from Imery's chemicals, Lompoc, CA, USA, were evaluated against the red flour beetle, (Herbst). The efficacy of the silica two powders was evaluated by exposing 10 adults of to twelve different concentrations of silica powder 1 and 2 for 12, 24, 36, and 48 h. Mortality assessments were made after 14 d, and data on adult progeny production were recorded at 42 d.

Significance of milling methods on brown teff flour, dough, and bread properties.

Teff (Eragrostis tef) has gained wide popularity mainly attributed to its gluten-free nature catering the needs of gluten-sensitive population. The higher water absorption capacity and gelling properties of teff flour promote its food applications, especially in the baking sector. The nutritional and sensorial properties of teff flour have been studied by incorporating with wheat flour at different proportions, but no study has reported the impact of various milling methods on the rheological and bread-making properties of teff flour.

Effect of ozone, lactic acid and combination treatments on the control of microbial and pesticide contaminants of fresh vegetables.

Background: Fruit and vegetable consumption has increased due to their tremendous health benefits. However, recent studies have shown that contaminated products may serve as vehicles for foodborne pathogens and harmful chemicals. Therefore, fresh vegetables must be decontaminated before consumption to ensure food safety.
