[The activity of sorbic acid against mycotoxin forming microorganisms (author's transl)]
Abstract:
Potassium sorbate at a concentration of 200-400 ppm inhibits mycotoxin forming Aspergillus versicolor at a pH of 5.7-5.9 in culture media and fermented sausages.
Insights
Potassium sorbate effectively inhibits the growth of mycotoxin-producing Aspergillus versicolor. This preservative is effective in both culture media and fermented sausages at specific concentrations and pH levels.
Area of Science:
- Food microbiology
- Food preservation science
Context:
- Mycotoxins produced by Aspergillus species pose a significant risk to food safety.
- Fermented sausages are susceptible to spoilage and mycotoxin contamination.
- Controlling fungal growth is crucial in food production.
Purpose:
- To evaluate the efficacy of potassium sorbate in inhibiting Aspergillus versicolor.
- To determine the optimal conditions (concentration and pH) for inhibition.
Summary:
- Potassium sorbate, at concentrations ranging from 200-400 ppm, demonstrated significant inhibition of mycotoxin-producing Aspergillus versicolor.
- Effective inhibition was observed in both laboratory culture media and fermented sausage models.
- The optimal pH range for potassium sorbate's efficacy was found to be 5.7-5.9.
Impact:
- Provides a scientific basis for using potassium sorbate as a food preservative against Aspergillus contamination.
- Contributes to the development of safer fermented food products.
- Highlights the importance of pH control in conjunction with chemical preservatives.
