The researchers developed a candy made from calamansi rind to help the environment and provide a healthy, inexpensive snack. Calamansi is commonly found in Southeast Asia, including the Philippines, and is rich in Vitamin C. The researchers hypothesized that calamansi rind can be made into a sweetened candy and that this candy would contain nutritional values and last a certain period of time if not consumed. They aimed to test how calamansi rind candy would affect the body.
