Abstract

This research aimed to evaluate the shelf life of pegagan (Centella asiatica (L) Urban) tea using the Accelerated Shelf Life Testing (ASLT) method by applying the Arrhenius Model since its widely known for its various health benefits, including its ability to enhance cognitive function and exhibit antioxidant effects. The ASLT method was employed to accelerate the chemical and physical changes in the product, thereby enabling a shorter estimation of shelf life compared to conventional methods. In this research, samples of pegagan tea were packaged in paper sacks, aluminum foil, and vacuum-sealed plastic and stored at temperatures of 15, 30, and 45 °C for 28 days, with observations conducted every 7 days. The Arrhenius Model was utilized to predict the rate of chemical reactions in the product, taking into account the temperature's influence on these changes. The data were analyzed using Analysis of Variance (ANOVA) at a 5% confidence level. If the ANOVA results showed significant differences, Duncan Multiple Range Test (DMRT) was further conducted. The results of the observations indicated that storage temperature and packaging type significantly influenced the yield value and pH value, but had no significant effect on the moisture content of pegagan tea. The estimated shelf life of pegagan tea for 28 days using paper sack packaging at temperatures of 15, 30, and 45 °C was 173, 616, and 195 days, respectively. For aluminum foil packaging, the estimated shelf life was 189, 661, and 205 days at the same temperatures. As for vacuum-sealed plastic packaging, the estimated shelf life was 551, 192, and 597 days at the respective temperatures. The findings of this research are expected to provide valuable information for manufacturers and consumers regarding the shelf life of pegagan Tea. Additionally, the research aims to offer a scientific basis for appropriate packaging and storage practices to better maintain the product's quality.

Abstract

This research aimed to 1) Determine the characteristics and antioxidant activity of Beluntas Tea with the addition of smashed ginger as a functional beverage; 2) Identify the best formulation for Beluntas tea with ginger as a functional beverage. This research utilized a Completely Randomized Design with two factors: Beluntas tea leaves and smashed ginger with three treatments. The treatments for Beluntas leaves consisted of 70%, 50%, and 30% (w/w). Meanwhile, the treatments for smashed ginger were 30%, 50%, and 70% (w/w). Data were analyzed using ANOVA, and if there were significantly different treatment effects, the Duncan 5% test was applied. Based on the analysis, the treatment with the highest pH value was B3J3 with a value of 7.17. The highest antioxidant value was found in treatment B2J3 with a value of 3.21%, with a Beluntas tea leaves to smashed ginger weight ratio of 1:1.4 g/g. The highest tannin content was observed in treatment B1J1 with a value of 21.85%. The highest yield was obtained from treatment B2J1 with a value of 0.96%. The best treatment based on organoleptic tests was treatment B2J2 with a value of 2.84, which was preferred over the other treatments.

Abstract

This research investigates the impact of drying temperature on the antioxidant content of Beluntas leaf tea (Pluchea indica L.). Beluntas, a widely recognized medicinal herb, is renowned for its potential health benefits attributed to its antioxidant properties. This quantitative study employs a Factorial Completely Randomized Design with two factors: the drying time of Beluntas leaves (factor W) and the drying temperature (factor S). The research aims to evaluate the effects of drying time and temperature of Beluntas leaves on pH, yield, moisture content, antioxidant content, tannin content, and organoleptic properties of Beluntas leaf tea. Drying times of 120, 140, and 160 minutes were used, while drying temperatures were 50, 60, and 70°C. Beluntas leaf tea was then brewed with 200 ml of hot water at 90-100°C temperatures and steeped for 10 minutes. The results of the research can be summarized as follows: 1) Drying temperature and time significantly affect pH, yield, moisture content, antioxidant content, and tannin content. Higher drying temperatures and longer drying times decrease, pH, yield, moisture content, antioxidant content, and tannin content. 2) The optimal treatment of drying temperature and time to obtain optimal antioxidant content is in sample S1W2 (drying temperature of 50°C for 140 minutes) with a moisture content of 7.74%, pH of 5.92, yield of 74.66%, antioxidant content of 59.12%, and tannin content of 14.90%. 3) Based on organoleptic tests, the sample preferred by the panelists is S3W2 (drying temperature of 70°C for 140 minutes) with a tea color that tends towards greenish-yellow, slightly characteristic aroma of Beluntas, non-bitter taste, and a pleasant aftertaste. The results indicate a significant impact of drying temperature on the antioxidant content of Beluntas leaf tea, with clear trends observed with varying temperatures. Understanding the relationship between drying temperature and antioxidant content is crucial for optimizing the production process of Beluntas leaf tea to maximize its health-promoting properties. This research provides valuable insights into the cultivation and processing of Beluntas as a functional beverage with enhanced antioxidant activity.
