Some of the reasons why palm sugar is healthier than granulated sugar is that the calories contained in palm sugar are smaller than white sugar so palm sugar is often referred to as low-calorie sugar, and palm sugar also has a lower glycemic index, namely of 35 while in granulated sugar the glycemic index is 58. The optimal way to improve the structure of melted sugar is by processing it into granular sugar, namely through re-melting of molded sugar with the addition of water into a sugar solution. The addition of granulated sugar and seed was found to have an effect on the yield, total sugar, sucrose, and the level of preference for color, taste and aroma, but decreased water content, reducing sugar, browning index and aroma level.The best treatment is the addition of 30% granulated sugar with a seeding temperature of 120 0C, in general it meets the requirements of SII where the water content, 2.75%, reducing sugar 4.35%, sucrose 81.14, total...
