Betel (Piper betle L.) vines are cultivated for its nutrition and medicinal properties. Good as it is, betel leaves are highly perishable. Hence, it posses challenge in commercialisation of betel leaves. Therefore, the current study aimed to investigate the effect of different drying conditions, i.e., hot-air oven drying at 40 (HAD-40), 50 (HAD50), and 60°C (HAD-60) and freeze drying (FD), on the nutritional values, physical, chemical, and functional properties of betel leaves powder. Hot-air oven drying at 60°C was the most effective method to preserve the nutrients of dried betel leaves with proximate compositions of 8.80% moisture, 22.81% crude protein, 5.40% crude fat, 12.02% crude fibre, 12.09% ash, 50.91% total carbohydrate, and 343.44 kcal/100 g energy.
