The purpose of this study was to serve a standard of the good quality control and shelf-life of food and beverage served from the vending machines. So it was performed to examine the temperature (internal & external environmental, food itself), pH, Aw, POV and microbiological quality of Adlay tea and Wheat noodles served from the vending machines based on storage time in the machines. They were assessed to find the critical control point(CCP) during each of the production, delivery, purchasing phases from the vending machines. The result of this study can be summarized as follows: 1. The temperature of foods inside the vending machines was ranged from 4$0^{\circ}C$ to 45$^{\circ}C$. It was in the range of dangerous zone. The average temperature of food showed 71$^{\circ}C$ for Adlay tea and 74$^{\circ}C$ for Wheat noodles. As a result of measuring pH and Aw, they had potential danger. 2. Even though POV was low, it increased as the time passed. 3. As a result of microbial analysis, it showed that the amount of total plate count and coliforms were increased ten times after 1 day respectively. Wheat noodles' coliform and total plate counts exceeded standard value in 1 day. As a result of food poisoning bacteria, it was negative in sample against Vibrio parahaemolyticus, Salmonella, Staphylococcus aureus.
