Abstract:
Background: Public interest and awareness of the use of functional food as an obesity nutrition
therapy are increasing.
Objective: This study aims to analyze the content of energy, macronutrients, minerals (magnesium,
manganese, and potassium), and bioactive components (fiber, β-glucan) in Indonesian varieties of
brown rice compared to white rice, to provide precise information on the nutritional content of brown
rice as a functional food in obesity nutrition therapy.
Methods: This research took the form of a laboratory analysis to identify the content of energy, macronutrients,
fiber, β-glucan, magnesium, manganese, and potassium in brown rice varieties Sinta Nur.
The energy content of rice was analyzed using bomb calorimetry; macronutrients were analyzed by
spectrophotometry, gravimetric extraction, and acid-base titration; dietary fiber, and β-glucan were
analyzed by enzymatic methods; and mineral contents were analyzed by spectrophotometry and
atomic absorption spectrophotometry.
Results: The results demonstrated that the energy and macronutrient content of brown rice are higher
than white rice. However, brown rice also has dietary fiber and β-glucan contents that are 5 times
higher than white rice. For the macronutrient, in brief, magnesium content was 7.7 times higher, potassium
was 5.7 times higher, and manganese was 1.59 times higher within the brown rice. Cooked
rice is known for lower nutritional value, but the nutritional value of Indonesian brown rice is still
higher than white rice.
Conclusion: The results of this study indicate that brown rice has nutrient content and bioactive
components that allegedly contribute to higher obesity intervention than white rice.
