Abstract
Bilimbi leaves as a functional food can be used as a non-pharmacological antihypertensive. This plant is processed into herbal tea as herbal beverage. This study aimed to investigate the acceptability and shelf life for Bilimbi leaves tea product. This study was an experimental study using 4 wet leaves formulas which were dried into tea. Tests were carried out towards 15 semi-trained panelists and 30 consumer panelists. bilimbi leaves tea were stored for 14 days at 25°C, 35°C and 45°C by measuring the water content parameter and total microbes. Data were calculated and analyzed by using Kruskal Wallis test and Arrhenius equation. The analysis results of Arrhenius equation in the hedonic quality test of semi-trained panelists as whole highest score in formula 4, but the taste parameter score was lower. Meanwhile, in the hedonic test of consumer panelist, the highest score was in formula 2 with better taste parameter score overall. The results of Kruskal Wallis test showed that there was a significant difference (p<0.05). The highest water content of Bilimbi leaves tea product was stored at 45oC, while the total microbes of product met the standard. Tea Stored at 25°C has a longer shelf life for 112 days. It concluded that formula 2 (7 grams/150 ml of water) has better acceptability with the best shelf life store at 25°C.
