Making Pectin from Orange Peel Waste (Citrus Sinensis) by Ultrasonic Wave Extraction Method Using Sulfuric Acid Solvents (H2SO4)

Introduction

Pectin is a valuable compound used in various industries, including the production of jelly, jam, thickening agents, stabilizers, and emulsifiers. The increasing demand for pectin has led to the exploration of alternative and sustainable sources of this compound. One such source is orange peel waste (Citrus sinensis), which is rich in pectin. In this study, we investigate the extraction of pectin from orange peel waste using the ultrasonic wave extraction method and sulfuric acid solvents (H2SO4).

The Importance of Pectin

Pectin is a complex carbohydrate found in the cell walls of plants, particularly in the skin and core of fruits. It is a key component in the production of food products, such as jams, jellies, and marmalades. Pectin is also used as a thickening agent, stabilizer, and emulsifier in various industrial applications. The increasing demand for pectin has led to the exploration of alternative and sustainable sources of this compound.

Research Methodology

The extraction process was carried out using the ultrasonic wave extraction method, which involves the use of high-frequency sound waves to break down the cell walls of the orange peel waste. The extraction process was carried out for 30 minutes at 70°C using H2SO4 solvents. The study tested variations of deposition time for 14, 16, 18, and 20 hours, as well as variations in ethanol concentration of 75%, 85%, and 95%. The pectin obtained was then applied to the rubber construction process with a variation of the ratio between pectin and rubber, which is 1:25; 2:25; 3:25; 4:25; and 5:25.

Characteristics of Pectin Produced

The characteristics of pectin produced include yield, water content, ash content, equivalent weight, metoxyl content, and galacturonic levels. From observations, the pectin yield ranged from 16.44% to 22.44%. Water content varies between 4.0% to 9.45%, while ash content ranges from 2.34% to 5.54%. The equivalent weight of pectin produced ranges from 510.20 mg to 865.07 mg with metoxil levels between 7.35% to 10.79% and galacturonic levels between 63.71% to 95.74%.

Results and Discussion

From the results of the study, the deposition time for 18 hours with a concentration of 95% ethanol produced the highest yield of pectin and the best characteristics that meet the IPPA (International Pectin Producers Association) standards. This discovery confirms the importance of setting the time of deposition and concentration of solvents in increasing the efficiency of pectin extraction. The results also show that the right ratio of pectin and rubber can increase the effectiveness of pectin as a thickening agent.

Benefits and Applications

The results of this study show the great potential of orange peel waste as a sustainable and economical source of pectin. The resulting pectin can be utilized in various industrial applications, including the manufacture of food and other industrial products. Using orange peel waste not only provides a solution for waste management, but also increases the added value of the previously neglected material.

Conclusion

This study contributes to the development of more efficient and sustainable pectin extraction technology, as well as opening the way for further exploration in the use of environmentally friendly natural resources. The results of this study show the potential of orange peel waste as a sustainable and economical source of pectin, and highlight the importance of setting the time of deposition and concentration of solvents in increasing the efficiency of pectin extraction.

Future Directions

Future studies can explore the use of other natural resources as a source of pectin, and investigate the effects of different extraction methods on the characteristics of pectin produced. Additionally, the study can be extended to explore the use of pectin in various industrial applications, such as the manufacture of food and other industrial products.

Recommendations

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

The use of orange peel waste as a sustainable and economical source of pectin is recommended.
The deposition time and concentration of solvents should be optimized to increase the efficiency of pectin extraction.
The right ratio of pectin and rubber should be used to increase the effectiveness of pectin as a thickening agent.
Further studies should be conducted to explore the use of other natural resources as a source of pectin and to investigate the effects of different extraction methods on the characteristics of pectin produced.

Limitations
