The use of essential oils in foods has attracted great interest, due to their antagonistic action against pathogenic microorganisms. However, this action is undesirable for probiotic foods, as products containing Lactobacillus rhamnosus. The aim of the present study was to measure the sensitivity profile of L. rhamnosus and a yogurt starter culture in fermented milk, upon addition of increasing concentrations of cinnamon, clove and mint essential oils. Essential oils were prepared by steam distillation, and chemically characterised by gas chromatography-mass spectrometry (GC-MS) and determination of density. Survival curves were obtained from counts of L. rhamnosus and the starter culture (alone and in combination), upon addition of 0.04% essential oils.... |

In this research an innovation in the manufacture of dulce de leche by vacuum evaporation is presented, based on the addition of Staphylococcus xylosus. The culture growth, lactic acid bacteria, pH, acidity, water activity, and lactose and sucrose contents were monitored. The cell counting of S. xylosus varied from log10 6.22cfu g-1 to log10 6.83cfu g-1. Lactic acid bacteria naturally occurring in the milk varied from log10 3.62cfu g-1 to log10 4.38cfu g-1 (90th day of storage). The pH was favourable to the growth of S. xylosus, showing the viability of using this culture in this kind of product. |
