Pulsed electric field for shalgam juice: effects on fermentation, shelf-life, and sensory quality.

Background: Pulsed electric field (PEF) has become a reality in the food industry as a non-thermal application. PEF is used due to its benefits such as increasing the extraction of anthocyanin or other bioactive substances, shortening the fermentation time, and reducing the microbiological load by electroporation. This study aimed to determine the effect of PEF pretreatment on the fermentation, chemical, microbiological, and sensory properties of shalgam juice.

Determination of an effective agent combination using nisin against Salmonella biofilm.

This present study aims to determine the lowest concentration effects of the assayed different antibiotics; antimicrobial agents alone and their combinations with nisin were investigated to prevent the biofilm formation and break down the biofilm structure of Salmonella. While the combination of nisin and EDTA showed a synergistic effect against Salmonella strain, chlorhexidine digluconate and streptomycin with nisin showed a partial synergetic effect; citric acid and sulfonamides with nisin showed an indifferent effect. The use of citric acid and chlorhexidine digluconate alone was very effective in Salmonella inhibition.

A study on rheological properties, sensory evaluation and shelf life of ayran-shalgam mixtures.

Ayran, a dairy-based fermented beverage, and shalgam, a plant-based fermented beverage were mixed [25% ayran + 75% shalgam (v/v), 50% ayran + 50% shalgam (v/v) and 75% ayran + 25% shalgam (v/v)] and rheological data were obtained at different temperature levels (4-12 °C). Power law model was used to describe the data. Temperature had no effect on the flow behavior index, but it affected the consistency index of the mixtures.

Mathematical Models for the Biofilm Formation of and on Stainless Steel Surface in Whole Milk.

Biofilm formation of , and in milk on stainless steel were monitored at 55°C, 60°C, and 65°C for various incubation times. Although species of showed a rapid response and produced biofilm within 4 h on stainless steel, a delay (lag time) was observed for . A hyperbolic equation and a hyperbolic equation with lag could be used to describe the biofilm formation of and , respectively.

Forecasting of COVID-19 infections in E7 countries and proposing some policies based on the Stringency Index.

COVID-19 infection data of Emerging 7 (E7) countries, namely Brazil, China, India, Indonesia, Mexico, Russia, and Turkey were described by an empirical model or a special case of this empirical model. Near-future forecasts were also performed. Moreover, the causalities between the Stringency Index's indicators and total cases in E7 countries in COVID-19 period were examined.
