by ADMIN 108 views

Introduction

Kencur rice drinks are a traditional Indonesian beverage known for their distinctive taste and health properties. However, the production process involves the addition of preservatives such as sodium sorbat (Na-Sorbat), which can affect the quality and acid content of the drink. This study aims to determine the effect of the concentration of sodium sorbat and the length of storage on the quality of kencur rice drinks.

Background

Kencur rice drinks are a popular traditional beverage in Indonesia, known for their unique flavor and health benefits. However, the production process involves the addition of preservatives such as sodium sorbat (Na-Sorbat) to extend the shelf life of the product. Sodium sorbat is a commonly used preservative in the food and beverage industry due to its effectiveness in preventing fungal growth and several types of bacteria. However, the use of sodium sorbat can have a significant impact on the quality and acid content of the drink.

The Effect of Sodium Sorbat Concentration on the Quality of Kencur Rice Drinks

The results of this study showed that various concentrations of Na-Sorbat had a significant effect on the total acid content of the kencur rice drinks. The concentration of Na-Sorbat 0 ppm, which is a treatment without additional preservatives (KJ), showed the highest total acid level of 0.70%, while the treatment with a concentration of Na-Sorbat 750 ppm (K4) produced the lowest total acid of 0.50%. This shows that an increase in the concentration of Na-Sorbat can reduce the acid content in drinks, which may be caused by the ability of sodium sorbat in inhibiting the growth of microorganisms that can cause fermentation.

Analysis of the Impact of the Concentration of Sodium Sorbat

Sodium sorbat is a preservative that is commonly used in the food and beverage industry because it is effective in preventing fungal growth and several types of bacteria. In the context of kencur rice drinks, the addition of Na-Sorbat aims to extend the shelf life of the product. However, the resulting effect can vary depending on the concentration used. In this case, low concentrations can increase product resistance to damage without significantly affecting the taste, while high concentrations tend to reduce total acid, which can have an impact on the taste and aroma of drinks.

The Effect of Storage Time on the Quality of Kencur Rice Drinks

The length of storage also plays an important role in determining the quality of kencur rice drinks. Although this research does not specifically investigate the effect of shelf time, generally, the longer the product is stored, the higher the possibility of changes in quality, both physical and chemical. This phenomenon is often associated with chemical reactions that occur during storage, such as oxidation and fermentation, which can reduce the quality of drinks.

The Interaction Between Sodium Sorbat Concentration and Storage Time

The interaction between sodium sorbat concentration and storage time can have a significant impact on the quality of kencur rice drinks. The results of this study showed that the combination of high sodium sorbat concentration and long storage time can lead to a significant reduction in the total acid content of the drink. This suggests that the use of sodium sorbat can have a cumulative effect on the quality of the drink, and that the concentration of sodium sorbat used can affect the rate of degradation of the drink.

Conclusion

The use of sodium sorbat in kencur rice drinks can have a significant impact on the total acid content and overall quality of the product. Through this study, it appears that the right concentration of sodium sorbat not only helps maintain product safety, but can also affect the taste. Therefore, it is important for producers to consider the balance between the use of preservatives with its impact on the quality of drinks so that consumers can still enjoy fresh and high-quality kencur rice drinks.

Recommendations

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

  • The use of sodium sorbat in kencur rice drinks should be carefully considered, taking into account the concentration used and the length of storage time.
  • Producers should aim to use the minimum concentration of sodium sorbat necessary to maintain product safety, while also considering the impact on the taste and aroma of the drink.
  • Further research is needed to investigate the effect of sodium sorbat concentration and storage time on the quality of kencur rice drinks, and to develop guidelines for the safe use of sodium sorbat in the production of kencur rice drinks.

Limitations of the Study

This study has several limitations that should be noted:

  • The study only investigated the effect of sodium sorbat concentration and storage time on the quality of kencur rice drinks, and did not consider other factors that may affect the quality of the drink.
  • The study used a limited number of samples, which may not be representative of the wider population of kencur rice drinks.
  • The study did not investigate the effect of sodium sorbat concentration and storage time on the sensory properties of the drink, such as taste and aroma.

Future Research Directions

Based on the results of this study, the following future research directions can be suggested:

  • Investigate the effect of sodium sorbat concentration and storage time on the sensory properties of kencur rice drinks, such as taste and aroma.
  • Develop guidelines for the safe use of sodium sorbat in the production of kencur rice drinks.
  • Investigate the effect of other preservatives on the quality of kencur rice drinks.
