The Effect of Sodium Metabisulfite Concentration and Luran Cassava Immersion Length on the Quality of Gaplek

Introduction

Gaplek, a traditional food made from cassava tubers, has been a staple in various regions of Indonesia for centuries. However, the processing of gaplek requires special attention to maintain its quality and safety. This study aims to investigate the effect of sodium metabisulfite concentration and luran cassava immersion length on the quality of gaplek. The addition of sodium metabisulfite is a common practice in food processing, including in the production of gaplek, to prevent oxidation and slow down the decay process. However, the optimal concentration of sodium metabisulfite and the length of immersion of cassava slices are crucial factors in determining the quality of gaplek.

The Concentration of Sodium Metabisulfite in the Gaplek Process

Sodium metabisulfite is a preservative that is widely used in food processing to prevent oxidation and slow down the decay process. In the production of gaplek, sodium metabisulfite is added to the immersion process to maintain the color, taste, and texture of the product. However, the concentration of sodium metabisulfite used is critical in determining the quality of gaplek. A concentration that is too low may not be effective in preventing damage, while a concentration that is too high can cause side effects for consumer health.

The addition of sodium metabisulfite in the immersion process is expected to prevent the growth of microorganisms and maintain the quality of gaplek. However, the optimal concentration of sodium metabisulfite is still unknown. Therefore, this research focuses on determining the optimal concentration of sodium metabisulfite that gives the best results.

Long Soaking and Gaplek Quality

The length of immersion of cassava slices is another important factor in determining the quality of gaplek. A long immersion process can help sodium metabisulfite seep into the slices of cassava, making it effective in preserving the material. However, soaking that is too long can make the texture of cassava become soft and lose its original taste.

Analysis of the quality of gaplek includes several parameters, such as the level of humidity, color, aroma, and texture. By paying attention to these two factors - the concentration of sodium metabisulfite and soaking time - this research seeks to find the best combination that produces high-quality and safe cassava for consumption.

The Importance of Sodium Metabisulfite Concentration

Sodium metabisulfite concentration is a critical factor in determining the quality of gaplek. A concentration that is too low may not be effective in preventing damage, while a concentration that is too high can cause side effects for consumer health. Therefore, it is essential to determine the optimal concentration of sodium metabisulfite that gives the best results.

The optimal concentration of sodium metabisulfite is expected to be between 0.1% and 0.5%. This concentration range is expected to be effective in preventing damage and maintaining the quality of gaplek. However, further research is needed to confirm the optimal concentration of sodium metabisulfite.

The Importance of Luran Cassava Immersion Length

Luran cassava immersion length is another critical factor in determining the quality of gaplek. A long immersion process can help sodium metabisulfite seep into the slices of cassava, making it effective in preserving the material. However, soaking that is too long can make the texture of cassava become soft and lose its original taste.

The optimal immersion length of cassava slices is expected to be between 2 and 4 hours. This immersion length range is expected to be effective in preserving the material and maintaining the quality of gaplek. However, further research is needed to confirm the optimal immersion length of cassava slices.

Conclusion

The effect of sodium metabisulfite concentration and luran cassava immersion length on the quality of gaplek is an important aspect in the production of cassava. By using a factorial complete random design (RAL), this research is expected to provide new insights on how gaplek processing can be done more effectively. The results of this study can be a reference for local food producers in improving the quality of their products, as well as maintaining valuable culinary traditions.

With the application of appropriate preservation techniques, gaplek will not only have good quality, but can also last longer, so that it is increasingly preserving the existence of this traditional food in the community.

Recommendations

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

The optimal concentration of sodium metabisulfite is between 0.1% and 0.5%.
The optimal immersion length of cassava slices is between 2 and 4 hours.
Further research is needed to confirm the optimal concentration of sodium metabisulfite and the optimal immersion length of cassava slices.
Local food producers should use the optimal concentration of sodium metabisulfite and the optimal immersion length of cassava slices to improve the quality of their products.

Limitations of the Study

This study has several limitations, including:

The study only investigated the effect of sodium metabisulfite concentration and luran cassava immersion length on the quality of gaplek.
The study did not investigate the effect of other factors, such as temperature and pH, on the quality of gaplek.
The study only used a factorial complete random design (RAL) to investigate the effect of sodium metabisulfite concentration and luran cassava immersion length on the quality of gaplek.

Future Research Directions

Future research should investigate the effect of other factors, such as temperature and pH, on the quality of gaplek. Additionally, further research is needed to confirm the optimal concentration of sodium metabisulfite and the optimal immersion length of cassava slices.
