| dc.description.abstract | Staphylococcus aureus is one
microorganism which caused food-borne disease.
This bacteria contamination is very easy due to it
exists in air, dust and contaminated equipment. Food
contamination can occur during or after handling
process such as on meat products, chicken, milk,
fermented food items, vegetables, fish products and
etc. The bacteria can cause food poisoning, so it is
necessary to detect the growth of this bacteria in the
food and food product before it is consumed.
Staphylococcus aureus on food products can be
detected using label indicator by the label color
changing. The label was attached inside the food
package. Many potential media can be used as label
material. One of them is mannitol salt agar (MSA).
MSA can give' information Staphylococcus aureus
growth on product by color changing from red to
orange and yellow. This changing is irreversible. The
color changing occur due to volatile acid and
mannitol fermentation on MSA by Staphylococcus
aureus result on pH reducing of the media, and then,
once it will change phenol red color containing in
MSA turn to orange and then yellow. The objective
of research was to identify MSA media as
Staphylococcus aureus detection label. The
examination was conducted on petri dish
approximately 2 cm from Staphylococcus aurells
culture. The capability of label on detection
Staphylococcus aureus growth was starting from 516
per gram of colony. The color change from red (R
(red) 55, G (Green) 44 dan B (Blue) 41) to orange (R
(red) 47, G (Green) 38 dan B (Blue) 34). | id |
