Abstract

The teter plant is an herbal plant cultivated in Taro Village, rich in bioactive components with various health benefits, especially in its leaves. Taro villagers process teter leaves into a product called ‘loloh’ don teter. However, this product has the disadvantage of a short shelf life and is less desirable to the general public. As a solution, teter leaves can be processed into herbal tea. One important aspect in making herbal tea is the drying time. This study aimed to determine the effect of drying time on the Teter Leaf Herbal Tea characteristics and to obtained the appropriate drying time in making Teter Leaf Herbal Tea and its potential as a functional beverage. A Completely Randomized Design (CRD) was used with the treatment of drying time at 4 levels (12; 18; 24; and 30 hours at 50oC). The results showed that the drying time had a significant effect on the characteristics of Teter Leaf Herbal Tea. A drying time of 24 hours was the right time to produced herbal tea with a yield of 20.74%, moisture content of 7.21%, total phenols 40.71 mg GAE/g, total flavonoids 28.76 mg QE/g, total tannins 0.80 mg TAE/g, vitamin C 8.13 mg AAE/g, and antioxidant activity of 85.55%. Teter leaf has the potential to be developed into functional beverage.

Abstract

Functional food products are emerging due to increased public health awareness. Cardamom (Amomum cardamomum L.), a spice cultivated in Manukaya Village, Bali, is rich in flavonoids and essential oils such as 1,8-cineole, α-terpinyl acetate, α-terpineol, limonene, linalool, and α-pinene. These compounds act as natural flavorings and antioxidants, making cardamom a potential ingredient for functional ice cream. To enhance the ice cream’s appearance, natural colorants like dragon fruit peel waste, which are rich in anthocyanins, can be used. This study contributed to determine the optimal ratio of cardamom powder and dragon fruit peel puree to produce ice cream with favorable characteristics and functional potential. A Randomized Group Design (RGD) was applied with 10 treatment ratios (100:0; 10:90; 20:80; 30:70; 40:60; 50:50; 60:40; 70:30; 80:20; and 90:10) and two replications, totaling 20 experimental units. Ice cream was produced by mixing the ingredients according to each treatment, followed by freezing for 10 hours. The data were analyzed using ANOVA and Tukey’s test. The results indicated that the 10:90 ratio of cardamom powder to dragon fruit peel puree produced the best ice cream, with average sensory scores of 4.82 (slightly liked) for color, 4.65 (slightly liked) for taste, and 4.59 (slightly liked) for overall acceptance. This formulation also showed 20.19% antioxidant activity and had a rosy brown appearance with color values of L* 61.90, a* 10.64, and b* 3.85, supporting its potential as a functional food product.
