Other than being a thirst quencher, this tasty drink is a great source of vitamins and minerals, as these nutrients can be easily absorbed and metabolized by your body. No wonder fruit juice becomes a popular staple in many households and you will find it in the shopping carts of almost all grocery-shoppers in various supermarkets or mini markets. However, do you know that it’s not that complicated to make your own fruit juice?

The Faculty of Biotechnology, in collaboration of the Marketing, Public Relations and Admission Bureau of Atma Jaya Catholic University of Indonesia, shared this knowledge and skill to the students of St. Angela High School in Bandung. On December 13, 2017, facilitated by a team of faculty members and alumni of Faculty of Biotechnology, 400 students from the 11th and 12th grade actively learned how to make their own fruit juice.

The process begin by blending pieces of fruit of your choice with water and a blender, followed by filtration to obtain a smooth texture. The result is then mixed with sugar and citric acid. As a sweetener, sugar can also prevent microbial growth and therefore it increases the fruit juice’s shelf life. In addition, citric acid not only help preserve the juice, but also enhances the sourness of fruit juice and prevent it from turning browning. If you can’t get your hands on some citric acid, you may skip it, but the fruit juice may not remain visually pleasing as long as if you use the citric acid.

The shelf life of the juice is further extended by pasteurization, or heating up the mixture at 60-80oC (below water boiling temperature). The fruit juice can then be chilled, packed inside a clean bottle, and ready to quench your thirst! You can even keep it the refrigerator for up to 7-10 days.
