Probiotic Durian Beer and Bubble Tea with Kriza Calumba (#15)


We talk about probiotic durian beer, food science, and bubble tea.

Kriza Calumba is an assistant professor of the Department of Food Science and Chemistry at the University of the Philippines Mindanao. She previously received a Fulbright-CHED scholarship, which allowed her to pursue Master’s studies at Louisiana State University, USA. Her Master’s research was on beer with probiotic bacteria immobilised in durian rind powder. With her interest in probiotics, she also recently opened a probiotic bubble tea business in Davao City, Philippines. She is looking forward to communicating food science to more people as well as providing more health-promoting food options to the general public.

In our conversation, we talk about probiotic durian beer, food science, and bubble tea.
