| Abstract The study included testing to note the impact of four types of plant extracts are grape seed extract, mint, lemon grass and ginger tubers with three concentrations (25,10,5%) for both of them in the microbial status of the milk. For results of the study showed a slight decrease in the total number of microorganisms in transactions with added extracts because these extracts restricted the activity of microorganisms compared to the comparison sample and on the contrary, encouraged the increase in the number of lactic acid bacteria significantly compared with the experience of the comparison samples. As it was to add the plant extracts used a significant impact in the inhibition of growth of coliform is expected that the active substances in these extracts inhibited the growth of these bacteria significantly. As well as plant extracts led to the killing and inhibition of fungi largely because growth does not appear in all samples and concentrations of plant extracts, while the comparison sample was found where the growth of mold on the tenth day and the fifteenth of the period of conservation. This is a positive indication on the possibility of using these extracts in increasing the life of this product milk food. | ||
