Most of them purchase food or beverages from the inside-campus food service, canteens. However, during the Ramadhan festival, most of the canteens are closed. Therefore, many seasonal food stalls are open for business at "Bundaran ITS" starting at 15.00 until 20.00 WIB (West Indonesian Time Area), providing food or beverages for breaking the fast. Therefore, a survey was conducted to check the healthiness of the food, meaning the food colorant additive especially red colorants. Moreover, this study also examined relationships among healthy food awareness, behavioural intention toward healthy foods, and actual behaviour of the ITS consumers. Thirty-seven (37) samples were collected during two periods of survey, at 9-12 May 2019 and 28-29 May 2019. The collected samples focused on the samples that might have red colorants. The collected samples were classified into three categories: beverages (32.43%), ketchups (54.05%), and snacks (13.51%). Gratefully, none of them contained Rhodamine B.
