Abstract

Background: Coconut sugar is a sweetening product that has a lower glycemic index (GI) than granulated sugar, which can be processed into crystal form. GI value in food has a relationship with blood sugar levels in patients with type 2 diabetes mellitus. The quality of coconut crystal sugar can be seen from the evaluation of the quality. Objective: Evaluate the chemical quality (total sugar content, reducing sugar content, sucrose content, water content, ash content) and GI test of coconut crystal sugar from home industry production in Tanggeran Village, Banyumas.
Methods: The quality evaluation used a quantitative descriptive analysis design and the GI test used a one group pretest-posttest experimental study design. The test for total sugar, reducing sugar and sucrose content used the Luffschrool method, the water and ash content used the Gravimetric method, the dietary fiber used the AOAC method (2005) and GI test used the IAUC method. Statistical analysis used an independent t-test.
Results: The average values of total sugar, reducing sugar, sucrose, water, and ash content of coconut crystal sugar were 66,209%; 1,76%; 64,653%; 12,687% and 2,158%, which was only
reducing sugar that was appropriate with SNI quality requirements. The GI value of coconut crystal sugar was 53,72 (low GI) and granulated sugar was 72,62 (high GI). The results of the independent t-test showed that both did not have a significant difference in GI values (p=0,088). Meanwhile, the
levels of dietary fiber from both had significant differences (p=0,00).
Conclussions: Some of the chemical contents of coconut crystal sugar did not appropriate with SNI (SII 0268-85) quality requirements. The glycemic index value of coconut crystal sugar is low and granulated sugar is high.
Keywords: Coconut crystal sugar; Diabetes mellitus; Glycemic index; Quality.
