Abstract
Background: Canistel Fruit (Pouteria campechiana) is an underutilized nutritious tropical fruit containing Vitamin A and complex carbohydrates with high potentiality. Hence, the present study focused on a novel Canistel fruit (Pouteria campechiana)-based beverage.
Objective: This study aimed to develop innovative fruit-based beverages from underutilized but widely available Canistel fruit around tropical regions and determine its nutrient stability at different temperature treatments. Methods: The higher starchiness of fruit pulp was remedied through α-amylase enzyme treatment. The base formula was prepared with fruit pulp and coconut milk (at ratios of 1:2, 2:3, 1:1), followed by incorporating sugar and stabilizers. The two-way preservation techniques of pasteurization (85oC, 15 min) and sterilizing techniques (121oC, 15 min) were used. Sensory acceptance by a trained panel from each formula of beverages, i.e., fruit pulp: coconut milk at ratios of 2:3 from each technique, was analyzed for physical and nutritional properties, fatty acid composition, and antioxidants. Results: A significant difference (p<0.05) was found among two-way processing techniques for the pH, oBrix, viscosity, and titratable acidity, as well as total sugars, crude protein, and crude fibre. The predominant fatty acid in both beverages was lauric acid. Vitamin A contents (mg/kg) were 0.3±0. and 0.2±0.01, respectively. Conclusion: This study showed Canistel fruit as a viable source for upgrading nutritional status when paired with coconut milk and other ingredients, and both processing techniques retained vitamin A, which fulfilled 8 – 10 % of the daily requirement by 200 ml of beverage.
