摘要
Noni fruit (Morinda citrifolia L.) has many health-supporting compounds, but its biological extracts need protection against environmental impacts for stability and efficiency. To address this, microencapsulation is an advanced technology in food applications that require optimization of coating component and temperature regime. Gum arabic (GA) and maltodextrin (MD) were suitably combined at 2:1 ratio, which showed good and stable structure as well as successful microencapsulation efficiency of the enzymatic-ultrasonic assisted noni extract. A coating density of 20 % for the GA:MD formula was with highest performance. The heat setting of spray drying was optimized at 175 and 82 °C for inlet and outlet, respectively using response surface methodology with experimental validation of maximized TFC and TSC at 88.3 and 90.3 %, respectively. Noni microencapsulated powder was assessed via a series of reliably advanced techniques such as microscopy, spectrophotometry, diffraction, and calorimetry for structural properties. Noni powder was additionally tested for storage stability, heat exposure stability, and release efficiency in pH condition and in vitro digestive tract. Promising results were obtained with at least one year storage stability, better microcapsule stability at 60 and 100 °C, quite good release at pH 7.4, and suitable release efficiency in digestive tract simulation. These properties of microencapsulated noni powder open further scalability potential and various industrial applications.
