Effect on Insect Survival, Rheological Characteristics, and Baking Properties of Flour Canned in Air or in Nitrogen Atmospheres

Eggs, larvae, and adult insects (Tribolium castaneum) were hermetically canned with flour in air or in nitrogen atmospheres and stored at 21C. and 38C. After six months storage, it was found that none of the insects had passed through more than two stages of metamorphosis, and most died without a si...

Description
Summary:Eggs, larvae, and adult insects (Tribolium castaneum) were hermetically canned with flour in air or in nitrogen atmospheres and stored at 21C. and 38C. After six months storage, it was found that none of the insects had passed through more than two stages of metamorphosis, and most died without a single stage change. No significant rheological change occurred in doughs prepared from untreated flour and flour packed in different atmospheres. Rheological differences were noted in all samples as a result of storage temperature.
