Production of sweet sorghum liquid sugar in the first ratoon harvest

Abstract

Sorghum is a multipurpose food crop commodity. One of the benefits is by utilizing the stalks which contain sweet juice which can be processed into liquid sugar. This processed product in the form of liquid sugar from the sweet sorghum plant has the potential to meet the needs of the healthy sugar industry in the future. This study aims to determine the production of sweet sorghum plant liquid sugar in the first ratoon harvest. The research was arranged in the form of a completely randomized factorial design. The first factor consisted of two levels, namely Numbu Varieties and Super 1 Varieties. The second factor consisted of three levels, namely the storage time of sorghum stalks for 0, 3, and 6 days. The results showed that the best treatment was found in the treatment of sorghum stalks of the Numbu variety which were stored for 3 days with 35.4% yield of juice, liquid sugar with 44.01% reduced sugar content, 77.25% liquid sugar Brix content, and 3 flavor organoleptic results, taste 3.81 (like), aroma 3.50 (like), and color 3.72 (like).
