Abstract
En 中文
This study aimed to develop an antidepressant functional food using natural ingredients such as green tea and turmeric. One blank and three experimental gummy formulations were prepared by varying the concentrations of turmeric-infused oil and green tea extract. Proximate composition, including moisture, ash, crude protein, crude fat, and fiber, was analyzed using standard methods. Textural properties were evaluated, showing hardness values ranging from 89.97 ± 1.59 N to 128.30 ± 1.90 N (disc probe) and 79.38 ± 3.61 N to 110 ± 2.20 N (cylindrical probe). No microbial growth was detected at the time of manufacture. During 15-day shelf-life testing, microbial counts remained within acceptable limits, pH slightly decreased, and texture softened, though no visible changes occurred. Formulation III received the highest preference in sensory evaluation by 50 semi-trained panelists based on appearance, aroma, taste, color, texture, and overall acceptability. Bioactive analysis confirmed caffeine content between 80.25 ± 0.05 and 150.21 ± 0.09 µg/g and curcumin between 70.10 ± 0.04 and 90.89 ± 0.09 µg/g. Overall, the results demonstrate the successful development of a shelf-stable, palatable gummy product with acceptable nutritional, sensory, and physicochemical characteristics, supporting its potential application as a nutraceutical or functional food formulation.
