Abstract

In this study, some experiments were carried out in growing of miracle fruit under climate and soil conditions of Ho Chi Minh City. The agro-biological parameters are collected. The chemical analysis results showed that the essential oil, carotenoid, phytosterol, fatty acids, flavonoids, polyphenols, organic acids, saponin steroids, sugar reducing agent, uronic compounds all were present in the miracle fruits. The miraculin from miracle fruit which was extracted with 0.5M NaCl solution and purified by ion exchange chromatography (with Rexyn 101 resin) can change the citric acid into sweet taste (equivalent saccharose 0.4M). This particular trait will provide new opportunity for using miraculin in the pharmaceutical and food industries in the future.
