摘要：The purpose of this research was to observe vanillin retention and color changes during storage of concentrated vanilla extract at the low temperature (10°C), room temperature (30°C), and high temperature (55°C) for 49 days. The methodology of this research consisted of vanilla curing process, vanilla extraction, evaporation of vanilla extract, formulation of concentrated vanilla extract, and measuring the vanillin retention and color change.The best products of c oncentrated vanilla extract were made with formula containing 10 ml vanilla extract, 10 ml high fructose syrup (HFS) 55% and 3 ml of carboxyl methyl cellulose (CMC) solution 1% and that made with f ormula containing 10 ml vanilla extract, 1 5 ml glucose syrup 75°Brix and 3 ml of CMC solution 1%. The vanillin retention of both formulas had a trend to de s creas e . The pattern of vanillin retention and color change during storage of both formulas followed lin ear equations.The t emperature and period of storage significantly affected the color of concentrated vanilla extract. Both formulas did not show any differences in vanillin retention and color during storage at refrigerator and room temperature.
