Abstract
Local street-vended ice cream in the Philippines has been called “dirty” ice cream for due to unsanitary manufacturing processes. This study aims to know the sensory preference of University of Santo Tomas college students in Manila, Philippines on street vended ice cream and their awareness on the possible health hazards linked in the product. Also, this study aims to determine the bacteriological quality of street-vended ice cream per variant. Three different ice cream variants were evaluated by 100 college students, and microbiological test were also conducted. In the three different samples tested, Cheese-flavored street-vended ice cream showed the highest rate in the overall acceptability in terms of taste, appearance and texture. On all three samples, Enterobacter gergoviae, which is known to cause opportunistic infection amongst immune compromised individuals, was found present in all the three ice cream samples.

Significant difference in sensory properties was found in the three flavoured street-vended ice cream in terms of the overall acceptability, appearance, texture and flavour
Summary
Reported that ice cream is one of the major products in dairy industry and remains to dominate attention of large segment of the population. Its mixture is made of dairy products (e.g. whole milk, condensed milk, milk powder, cream) sweeteners (sugar, glucose) emulsifiers, stabilizers and colourings. Ice cream can serve as a topping, add-on or mix-in for other desserts. In the Philippines, tropical climate has contributed to the popularity of ice cream as a "summer treat". It is in line with other Filipino cold desserts as reported by Gimena [2] like fruit shakes, ice scramble and halo-halo (mixed sweetened fruits, beans, tapioca pearls, agar, added with crushed ice and evaporated milk) [2]
