Abstract

This study aims to determine the effect of ultraviolet light (UV-C) and irradiation duration on changes in pH and total dissolved solids on palm sugar during storage. The study was conducted using the treatment of UV-C lamp power and exposure time. The parameters measured were pH, and total dissolved solids and the measurements were repeated three times. The results showed that palm sugar palm juice treated with UV-C had a lower pH change rate than controls. The higher the power of the UV-C lamp used was able to retard the rate of change in the sap of the palm sugar. Turbidity, foaming, organic acid content and substances that are suspended in palm sugar are presumed to be a longstanding factor of irradiating ineffectiveness due to low UV light transmission. The effect of UV-C lamp power and prolonged irradiation is known to be able to maintain the stability of the total content of dissolved solids on palm sap
