The consumer trend toward safe and healthy food has spurred research and application of natural colors in traditional biscuit products to improve quality and sensory value. Perilla frutescens (L.) Britton is a member of the Lamiaceae family and is widely found in East Asian regions, where it is used as both a spice in cooking and in traditional medicine. It is rich in anthocyanins, a class of polyphenolic compounds that act as natural colorants and possess strong antioxidant properties. This study aimed to evaluate the extraction process of perilla leaf for enriching the total anthocyanin content, which is applied in coloring butter biscuits. The investigated factors included the sample-to-water ratio for extraction (1:10, 1:15, 1:20, and 1:25 g:mL), extraction temperatures (60°C, 70°C, 80°C, and 90°C), and extraction times (20, 25, 30, and 35 minutes). The obtained extract was analyzed for anthocyanin content using the pH differential method. The findings suggested that a sample-to-water ratio of 1:20 g:mL, an extraction temperature of 90°C, and an extraction duration of 30 minutes were the most suitable extraction conditions to achieve a high total anthocyanin content (1.70 mg.g-1 DW). The addition of perilla leaf extract (PLE) significantly affected the physical properties of the biscuits (diameter, yield, brightness, and hardness of the biscuits); the higher the amount of PLE added, the darker and crispier the biscuits became. Sensory analysis showed that biscuits supplemented with PLE were rated higher than the control in terms of texture, color, and flavor. The results showed that the biscuits that received the highest scores across all parameters were supplemented with PLE at a rate of 7.5%. Overall, the analysis suggests that it is possible to produce butter biscuits with a characteristic color and improved nutritional profile by adding PLE.
