Storm water runoff is increasingly assessed for fecal indicator organisms (e.g., Escherichia coli, E. coli) and its impact on contact recreation. Concurrently, use of autosamplers along with logistic, economic, technical, and personnel barriers is challenging conventional protocols for sample holding times and storage conditions in the field. A common holding time limit for E. coli is 8 h with ...

Refrigerated sweet potato puree is a convenient form of sweet potato that can be used as an ingredient in formulated foods. The microbiology of refrigerated sweet potato puree during storage for up to 5 weeks was evaluated. Because the puree was made by comminuting steam-cooked sweet potatoes before refrigeration, no naturally occurring vegetative bacterial cells were detected during a 4-week p...

This study evaluates the adaptative response to heat (63 degrees C) and the modifications in membrane fatty acid composition of Salmonella senftenberg after its growth in an acidified medium and after its exposure to combinations of acid and cold stresses. Cells were grown in Brain Heart Infusion (BHI) buffered at pH 7.0 and acidified up to pH 4.5 (fresh cultures) and kept at refrigeration temp...

Introduction: The demand for antimicrobial compound alternatives to replace synthetic additives is on the rise. In food commodities, use of synthetic antimicrobials based on herbal extracts is attracted attention. The present study aimed to assess the chemical, microbiological, and sensory properties of the yogurt samples treated with oregano extract (0%, 0.75%, 1%, and 1.5%) d...

Effect of retort processing on the shelf life and safety of ethnic Indian food product namely soya peas curry was investigated. Ready-to-eat soya peas curry was packed in laminated retort pouches and processed in a steam-air retort with overriding pressure. Time-temperature profile of processing was determined and the same was used for heat penetration characteristics. The thermal processing pa...

Results: There were no significant differences in semen quality associated with the shape of the centrifugation tube either for refrigerated (5 ̊C) or thawed semen. The g-force of centrifugation did affect semen quality. In refrigerated samples centrifuged at 250g, the percentage of sperm with normal apical ridges (NAR) was lower (P <.01) and the percentage of damaged acrosomes was higher (P <.0...

This work was aimed at enumerating the viable microorganisms in ripened Serra da Estrela cheeses, manufactured from both refrigerated and non-refrigerated milk, in various dairies located throughout the demarcated region. Scanning electron microscopy was used to analyze the microstructure, and thus aid in understanding possible differences in their microbiological profile. The cheeses were allo...

The effect of sodium benzoate on the quality attributes of improved tamarind beverage during storage was investigated. Tamarind beverages were produced according to a previously reported improved method, with or without chemical preservatives (100 mg/100 mL sodium benzoate). Tamarind beverage produced according to traditional processing method served as the control. The tamarind beverages were ...

The cold chain is responsible for perishable products preservation and transportation, maintaining a proper temperature to slow biological decay processes. Often the efficiency of less than ideal, significantly increasing food waste energy consumption. Refrigerated transport critical phase because its negative impact on consumption greenhouse gas emissions. It estimated that around 15% global f...
