Abstract Mathematical models have been developed to predict the probability of growth of spoilage moulds in response to various preservative systems in ready to drink beverages. A Box-Behnken experimental design included five variables, each at three levels: pH (2·8, 3·3, 3·8), titratable acidity (0·20%, 0·40%, 0·60%), sugar content (8·0, 12·0, 16·0 °Brix), and preservative concentrations (sodium benzoate and potassium sorbate, each 100, 225, 350 ppm). Duplicate samples were inoculated with a…

Optimisation of preservatives for dealcoholised red wine using a survival model for spoilage yeasts

Summary To optimise the application of preservatives in a new commercial dealcoholised red wine (DRW), a survival model of Rhodotorula mucilaginosa and Saccharomyces cerevisiae was developed. A

A Binary Logistic Regression Model as a Tool to Predict Craft Beer Susceptibility to Microbial Spoilage

A growth/no growth (G/NG) binary logistic regression model is developed that has good sensitivity and goodness of fit and provides the potential to predict craft beer susceptibility to microbial spoilage.

Quality Assessment of Sweet Cherry (Prunus avium) Juice Treated with Different Chemical Preservatives

This research was conducted to assess the quality of sweet cherry juice treated with sodium benzoate and potassium sorbate. The samples were packed in 1000 ml PET bottles and stored at ambient

Mathematical Models for the Effects of pH, Temperature, and Sodium Chloride on the Growth of Bacillus stearothermophilus in Salty Carrots

This study characterized and model germination, outgrowth, and lag (GOL) time and the exponential growth rate (EGR) of Bacillus stearothermophilus in salty carrot medium as a function of pH, temperature, and NaCl concentration.

Simulation and modelling of the effect of small inoculum size on time to spoilage by Bacillus stearothermophilus

The simulation approach provided potentially greater mechanistic insight into the causes of spoilage time variability, and supported the notion that the effects of biovariability and interactions among individual spores manifest at very low inoculum sizes.

Differentiation of the Effects of pH and Lactic or Acetic Acid Concentration on the Kinetics of Listeria Monocytogenes Inactivation.

P pH and lactic acid or acetic acid concentration on Listeria monocytogenes inactivation were studied in brain heart infusion broth using a three strain mixture and 4-D inactivation times were related to the level of undissociated lactic and acetic acids.

Acidulants and low pH

The pH and organic acid content of foods are two significant factors that may determine not only the types of organisms that will survive during storage but also their activities as spoilage

The effect of pH, sodium chloride, sucrose, sorbate and benzoate on the growth of food spoilage yeasts☆

All yeasts grew at 50% sucrose, with Z. bailii and Y. lipolytica were the species most tolerant of sorbate and benzoate preservatives at pH 5.0 and Z. hansenii, Z. rouxii and P. anomala grew at 15% NaCl, respectively.

Acetic, lactic and citric acids and pH inhibition of Listeria monocytogenes Scott A and the effect on intracellular pH.

The effects of acetic, lactic and citric acids and pH on the growth and intracellular pH (pHin) of Listeria monocytogenes Scott A and the effect of differing acid and pH environments on pHin was determined.
