Analysis of Mineral Content in Gadung Tubers (Dioscorea Hispida Dennst.) by Spectrophotometry Atomic Absorption

Introduction

Gadung tubers (Dioscorea Hispida Dennst.) are a type of wild tuber that grows in various habitats, including forests, yards, and plantations. These tubers are known to contain useful bioactive compounds, such as water-soluble polysaccharides, dioscorin, and diosgenin, which have been used to treat various diseases, including leprosy, fever, and as an antireumatical drug. This study aims to analyze the mineral content of Gadung tubers, specifically cadmium, potassium, calcium, and sodium, both in fresh and after boiling, as well as to determine the percentage of decreased mineral content due to the boiling process.

The Importance of Mineral Content in Gadung Tubers

Mineral content is an essential aspect of a food's nutritional value. Gadung tubers, being a wild food source, may contain varying levels of minerals, which can impact their nutritional value. The analysis of mineral content in Gadung tubers can provide valuable information on their potential health benefits and nutritional value. Potassium, for instance, is an essential mineral that plays a crucial role in maintaining healthy blood pressure, promoting bone health, and supporting muscle function. Calcium, on the other hand, is essential for maintaining strong bones and teeth, as well as supporting muscle function and nerve function. Sodium is also an essential mineral that helps regulate fluid balance in the body, while cadmium is a toxic mineral that can accumulate in the body and cause health problems.

Research Methods

This research was conducted using a dry destruction method to process Gadung tubers samples. Mineral content was tested using a spectrophotometry of atomic absorption with acetylene air at the appropriate wavelength, which is 228.8 Nm for cadmium, 766.5 nm for potassium, 422.7 nm for calcium, and 589.0 nm for sodium. This method allows for an accurate quantitative analysis of mineral content in the sample.

Research Results

The results showed that the mineral content in fresh Gadung tubers was as follows: cadmium (0.0011 ± 0.0083 mg/100g), potassium (265,2780 ± 0.4652 mg/100g), calcium (5,1015 ± 0, 0490 mg/100g), and sodium (8,3011 ± 0.0974 mg/100g). After boiling, the mineral content has decreased, with the following results: cadmium (0,0007 ± 0,0001 mg/100g), potassium (242,2823 ± 0.3017 mg/100g), calcium (4,1177 ± 0, 0370 mg/100g), and sodium (5,9178 ± 0.0702 mg/100g).

Analysis and Discussion

From the results obtained, it appears that Gadung tubers have varying mineral content. Potassium levels are the highest compared to other minerals, reflecting the potential of Gadung tubers as a natural source of potassium. Decreased mineral content after the boiling process may be caused by leaching, which is the process in which minerals dissolve in water during boiling. This shows the importance of processing techniques in maintaining the nutritional value of Gadung tubers.

The importance of this research not only lies in the disclosure of mineral content, but also in the health potential of the Gadung tubers themselves. With the presence of bioactive compounds and minerals contained, Gadung tubers can be considered as an alternative to nutritious food ingredients, especially in areas that still rely on local natural resources.

Conclusion

Based on this study, it can be concluded that Gadung tubers contain cadmium minerals, potassium, calcium, and sodium with different levels. The boiling process was proven to reduce the mineral content. This finding provides important insight into the processing of Gadung tubers to get the maximum benefit from the nutritional content and bioactive compounds. Going forward, further research is needed to explore other processing methods that can maintain the nutritional content of Gadung tubers.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research is needed to explore other processing methods that can maintain the nutritional content of Gadung tubers.
The use of Gadung tubers as a natural source of potassium and other minerals should be promoted, especially in areas that still rely on local natural resources.
