Optimization of Microwave-Assisted Extraction Process by Response Surface Methodology of Natural Anthocyanins from Rhodomyrtus tomentosa (Ait.) Hassk

Abstract

Rhodomyrtus tomentosa (Ait.) Hassk is a fruit that is gradually becoming popular in Vietnam with superior bioactive compounds. This study aimed to determine the natural anthocyanins from Rhodomyrtus tomentosa (Ait.) Hassk based on extracts and optimized RSM. The Box-Behnken design was shown the influence of the optimal conditions for the MAE procedure are 5.07 min, 206 W and 2.53 g/mL with the optimal anthocyanin content achieved Y = 133.88 mg/L, all reactions are within the threshold of the predicted value. The results are in line with the proposed model for the anthocyanin extraction (R2 = 0.9849).
