Impact of drying method as pretreatment for extraction of bioactive compounds from jambolan (Syzygium cumini (L.) Skeels)

Abstract Jambolan (Syzygium cumini (L.) Skeels) is an under-explored fruit rich in polyphenols, which are associated with health benefits, such as increasing resistance to oxidative stress, inflammatory processes and cardiovascular, platelet functions. These polyphenols can be obtained by extraction, but efficient standard method remains a challenge. In this context, work evaluated the impact of different pretreatments on jambolans obtain bioactive compounds aqueous extraction. An Air Circulation Oven (ACO) Lyophilization (LYO) were used pretreatments. addition, influence mass, temperature, cycle, time parameters studied extraction methods used: Percolated Solid-Liquid (PSL), Conventional (CSL), solid-liquid assisted ultrasound (USL). The yield was from 7.3% 46.3% (LYO), both using PSL method. eleven phenolic six anthocyanins detected High Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD), expressive amounts catechin cyaniding LYO sample and, these extracts showed higher concentrations compounds. CSL more ACO samples samples. Therefore, use drying pretreatment results high antioxidant potential for application food, cosmetic, pharmaceutical markets.
