Doogh is one of the most used fermented dairy drinks in Iran, whose durability and taste in the food industry is very important. The aim of this study was to investigate the antimicrobial effect of hydroalcoholic extract of salvia (Salvia officinalis), basil (Ocimum basilicum) and cinnamon on the durability of dough at ambient temperature.
Hydroalcoholic extracts of salvia, basil and cinnamon were extracted by maceration method. The antimicrobial effects of the extract of these three plants were determined by microdilution on yeast of Saccharomyces cerevisiae by determining minimum microbial inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), and then pH, acidity and antimicrobial effects of them in dough at ambient temperature over four weeks Checked out.
Based on the results of this study, the minimum inhibitory concentration of these extracts was between 6.25 and 12.5 mg/ml. Among studied extracts, salvia (Salvia officinalis), with a concentration of 0.62 mg/ml significantly decreased the yeast population of Saccharomyces cerevisiae in dough during four weeks (p<0.05). But basil (Ocimum basilicum) extract has only control effect and cinnamon extract has no antimicrobial effect.
Hydroalcoholic extract of salvia (Salvia officinalis), basil (Ocimum basilicum) and cinnamon can be used as an antifungal and antimicrobial agent as a natural preservative in dough and has an important role in consumer health.
