| Summary: | Milk which one of the most important food substance contained many important
nutrients that needed by health, but easily contaminated with bacteria. Due to that
reason researcher try to find the best way to sterilize milk, which is in this
research by electricity flow. This research used 3 treatments: first treatment used
250ml milk which already inoculated with 1,0 x 106 CFU/ml Escherichia coli and
electrified for 20 minutes with 10 V, second treatment with 15 V, and third
treatment with 20 V. From the Processed data, the total amount of bacteria
decreased in almost of all treatment, however the most significant result is on the
treatment group with 20 V electricity flow. Research result showed that 20 V
electricity flow for 20 minutes could decreased total amount of bacteria
Escherchia coli in milk until one log cycle colony forming unit. |
