EXPERIMENT OF PRODUCTION OF TEA BAG FROM POLYSCIAS FRUTICOSA L. HARMS PLANTED IN DAK LAK

Abstract

Polyscias fruticosa (L.) Harms is known as an herbal plant that provides health benefits to consumers. A research article investigated the conditions for producing small-leaved Polyscias tea bags, including the size of the dried material, drying temperature, water/material ratio, and brewing time. The results showed that drying small-leaved Polyscias at 80°C preserved higher levels of polyphenols, total saponins, and antioxidant capacity than small-leaved Polyscias that were finely ground and dried at 60°C, 70°C, 90°C, or 100°C. The content of polyphenols, saponins, and antioxidant activity are 6.76 (mgGAE/g NL), 3,51 (mgEE/g NL), and 67.5%, respectively. The product was then evaluated for the water/material ratio and brewing time to select appropriate tea brewing parameters. The most effective extraction of the compounds in small-leaved Polyscias tea was achieved with a water/material ratio of 30/1 and a brewing time of 15 minutes, the extraction efficiency of compounds in tea was the highest, with polyphenol content, saponin content, and antioxidant activity of 5.85 (mgGAE/g DW), 3.35 (mgEE/g DW), and 57.49%, respectively.
