Abstract
Forest honey is a high value local commodity with nutritional content and bioactive compounds that are beneficial for health. However, inefficient processing can reduce physicochemical quality and increase energy consumption. This study aims to develop energy saving technology in honey processing by utilizing sensible heat storage using SS 316 steelballs to improve the efficiency of the pasteurization and vacuum cooling processes. The material used was forest honey processed experimentally at the Lastrindo Engineering Laboratory with three variations of pasteurization temperatures (65 C, 75 C, 85 C) in treatments with and without steelballs. The method used included heating using a water bath to the target temperature followed by rapid cooling using vacuum cooling, with observations of changes in process temperature and water content. The results showed that the use of steelballs accelerated the achievement of pasteurization temperature, reduced process time, increased heat transfer efficiency, and accelerated the temperature reduction during cooling. A more significant reduction in water content occurred in the steelball treatment and all product quality met SNI 8664:2024. It was concluded that the application of SS 316 steel balls effectively saves energy and process time without compromising quality, thus potentially being applied in honey processing industries ranging from small and medium enterprises (SMEs) to large factories to improve production efficiency and product competitiveness.
