What is it about?

Kunun is a relished beverage consumed in Nigeria. It has a very shor shelf life of about 24h. In this study different pasteurization temperatures and different levels of sodium metabisulphite were used to extend the shelf life of this beverage.

Why is it important?

Processing of cereals into Kunun is laborious and there is need to preserve this beverage because of its short shelf life . This study has shown that pasteurization at 70degrees celcius followed by addition of 120ppm sodium metabisulphite preserves Kunun for up to 4 weeks.
