Physical, Chemical, Antioxidant, and Organoleptic Characteristics of Functional Beverages of Purple Leaf Leaf Extract (Ruellia tuberosa L.) and Rosella Flower Extract (Hibiscus sabdariffa L.)

Introduction

The human body is constantly exposed to free radicals, which are unstable molecules that can cause damage to cells and contribute to various diseases. To combat this, it is essential to consume foods rich in antioxidants, which can help maintain a balance between antioxidants and free radicals in the body. Purple leaf extract (Ruellia tuberosa L.) and rosella flower extract (Hibiscus sabdariffa L.) are known for their high bioactive compound content and excellent antioxidant activity. This study aims to investigate the physical, chemical, antioxidant, and organoleptic characteristics of functional beverages made from the combination of these two extracts.

Background

Free radicals are formed in the body due to daily activities, such as metabolism, exposure to environmental stressors, and consumption of processed foods. If the body lacks antioxidants, these free radicals can cause oxidative stress, leading to various degenerative diseases, including cancer, diabetes, and heart disease. Therefore, the intake of antioxidants through food is crucial to maintain a balance between antioxidants and free radicals in the body. Purple leaf extract and rosella flower extract have been shown to have high antioxidant activity due to their high content of bioactive compounds.

Methodology

This study employed a non-factorial completely randomized design (CRD) method, which consisted of five different ratios of purple leaf extract and rosella flower extract. The ratios were as follows: F1 (100%: 0%), F2 (70%: 30%), F3 (60%: 40%), F4 (50%: 50%), and F5 (0%: 100%). The analysis conducted included physical, chemical, antioxidant activity, and sensory analysis.

Results and Discussion

The results of this study showed that the comparison of purple leaf extract and rosella flower extract had a very significant effect (p <0.01) on the color index, total flavonoids, total phenol, total anthocyanin, antioxidant activity, percent inhibition, total acid, total solid solids, as well as Organoleptic parameters such as color, aroma, taste, and general acceptance. In addition, there was a significant effect (P> 0.05) on the hedonic viscosity.

The best ratio for this functional drink, based on the De Garmo method, was found to be a ratio of 50% purple leaf extract and 50% rosella flower extract. This shows that the balance of the two extracts creates functional drinks that not only have high antioxidant activity but also good palatability, making it interesting for consumption by the community.

Benefits and Added Value

Functional drinks resulting from the combination of purple kencana leaf extract and rosella flowers have significant benefits, especially in helping to fight free radicals and improve health. The antioxidants contained in these two extracts have the potential to prevent cell damage caused by oxidative stress, which is often the main cause of various degenerative diseases such as cancer, diabetes, and heart disease.

In terms of sensory, achievement in attractive colors, fresh aroma, and good taste make this drink not only healthy but also fun to enjoy. Therefore, the development of functional beverage products based on purple leaf extract and rosella flowers can be an attractive alternative for consumers who care about health and find the choice of innovative and delicious drinks.

Conclusion

This research not only provides scientific evidence of the health benefits of these plant extracts but also opens opportunities for further product development that can be marketed in the health drink market. The combination of purple leaf extract and rosella flower extract has the potential to create functional drinks that are not only healthy but also enjoyable to consume.

Future Directions

Future studies can focus on the development of new products based on the combination of purple leaf extract and rosella flower extract. Additionally, research can be conducted to investigate the potential health benefits of these extracts in specific populations, such as individuals with chronic diseases.

Recommendations

Based on the findings of this study, it is recommended that functional beverage products be developed using the combination of purple leaf extract and rosella flower extract. These products can be marketed as healthy and enjoyable alternatives for consumers who care about their health.

Limitations

This study had some limitations, including the use of a non-factorial completely randomized design method, which may not have captured the full range of effects of the different ratios of purple leaf extract and rosella flower extract. Additionally, the study only investigated the physical, chemical, antioxidant, and organoleptic characteristics of the functional beverages, and did not explore other potential benefits of these extracts.

Future Research

Future research can focus on investigating the potential health benefits of purple leaf extract and rosella flower extract in specific populations, such as individuals with chronic diseases. Additionally, research can be conducted to explore the potential benefits of these extracts in combination with other ingredients.
