| Abstract |
This study aimed to optimize pectin extraction from crude cacao shell (CS) powder using chemical method (pH 4 and 10, temperatures 60-80 degrees C), ultrasound-assisted extraction (UAE) method (sonication time 20-40 min), and enzymatic method (pectinase 0.5-1.0% v/v, temperature 40-60 degrees C, and time 120-240 min). The optimal extraction condition with highest CS pectin yield was enzymatic followed by chemical and UAE methods. The pectin extracted from cocoa shell from all extraction methods had the degree of esterification (DE%) greater than 50% which was categorized as high methoxyl (HM) pectin. The prebiotic activity and viscosity of pectin from the optimal extraction conditions with highest pectin yield for each extraction method were studied. Pectin extracted via UAE method with highest prebiotic activity (p & LE;0.05), was selected for edible coating of tomato and quality changes were evaluated during 30 days of storage at 4 degrees C. The results showed that tomato coated with pectin based edible coating (TWP) retained physicochemical properties (e.g., color, total soluble solid, pH, firmness, weight loss), and bioactivity (e.g., lycopene, total phenolic compound and antioxidant activity), compared with control (CON) and tomato coated with no pectin (TNP). In addition, the total viable count and yeast and mold count of TWP was the lowest among other treatments. Therefore, pectin-based edible coating was able to delay the quality changes and extend the shelf life of TWP sample up to 27 days at 4 degrees C. |
