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

摘要

Rhodomyrtus tomentosa (Ait.) Hassk is a fruit that is gradually becoming popular in Vietnam due to the diversity of bioactivities exhibited by its secondary compounds. The aim of this study is to quantify 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 proposed model also exhibited high coefficient of determination (R~2 = 0.9849) which indicates good approximation and high predictability.
