Making Herbal Tea from Palm Oil Leaves (Elaeis Guineensis Jacq): A Promising Innovation for Health and Sustainability

Tea is a popular beverage consumed globally, known for its refreshing sensation and numerous health benefits. The tannin content in tea provides a unique flavor and aroma, making it a favorite among tea enthusiasts. However, tea can be made from various types of plants, and one of the most interesting sources is palm oil leaves. These leaves have the potential to produce secondary metabolites such as phenol and flavonoids, which are known for their antioxidant properties.

The Rise of Palm Oil-Based Herbal Tea

Palm oil-based herbal tea is gaining attention as a healthy alternative to traditional tea. Palm oil leaves are easily accessible and rich in natural compounds that have potential health benefits. Phenol and flavonoids, for example, are known antioxidants that can provide protection against various diseases. By utilizing oil palm leaf waste, making herbal tea not only benefits health but also contributes to environmental sustainability.

Objective and Methodology

This article aims to explain the process of making herbal tea from oil palm leaves and assessing the quality standards and bioactive components contained in the product. The manufacturing method involves several important stages:

Leaf Preparation

Separation and Washing: Palm oil leaves are separated from the lid and washed thoroughly to remove any impurities.
Cutting: The leaves are then cut into a size of about 1 cm to facilitate the drying process.

Drying

Withering: The cut leaves are placed on a shelf and left to wither for 14 to 24 hours, allowing the water content to decrease.
Oxidation: The withered leaves are then blended to reduce the size of the powder and undergo an oxidation process to increase the taste and aroma of the tea.

Processing and Fermentation

Blending: The processed leaves are blended to reduce the size of the powder.
Fermentation: The blended leaves are placed in a cold and humid place for the fermentation process.
Drying: After fermentation, the leaves are dried in a drying cabinet with a temperature of 50 ° C, 90 ° C, and 110 ° C for 110, 130, and 150 minutes.

Quality Testing

Odor and Flavor: The final product is tested for its odor and flavor to ensure it meets the quality standards.
Color: The color of the tea is also evaluated to ensure it is consistent with the expected color.
Water Content: The water content in the tea is tested to ensure it is within the acceptable range.
Bioactive Content: The bioactive content in the tea is screened to identify the presence of triterpen/steroids, alkaloids, flavonoids, tannins, saponins, and glycosides.

Results and Conclusion

The quality testing of oil palm leaf herbal tea shows attractive results. The parameters tested include metal contamination, water content, water extract content, and bioactive content. The results show that the product is safe for consumption, with cadmium metal content at 0.303 ppm and lead 0.149 ppm, and arsenic is less than 0.0004 ppm. The water content in the sequential tea powder is 7.18%, 5.88%, and 3.92%, while the water soluble extract content recorded 8.6%, 5.96%, and 5.76%. The bioactive content screening shows that the positive herbal tea powder contains triterpen/steroids, alkaloids, flavonoids, tannins, saponins, and glycosides. The flavonoid level test also shows different variations depending on the drying temperature, with the highest yield on fresh leaves of 357.13 mg/100 g.

In conclusion, making herbal tea from palm oil leaves is a promising innovation with significant health potential. Variations in the temperature in the drying process affect the quality and bioactive concentration in the herbal tea produced. With the right use, oil palm leaves can not only be a refreshing source of drinks but also contribute to a healthy lifestyle and environmental sustainability. As a step ahead, further research can be done to explore the potential health benefits of this herbal tea and improve its production methods.
