Development of soluble herbal tea from mangaba (Hancornia speciosa Gomes) by freezedrying and atomization (spray drying) methods
mangaba; phytochemicals, soluble tea; herbal medicine, experimental design
Mangaba (Hancornia speciosa Gomes) is a native fruit of Cerrado that has shown antioxidant and anti-inflammatory potential, due to the presence of phenolic compounds, ascorbic acid, carotenoids and tocopherols, associated with prevention of hypertension and diabetes. An adequate extraction of these compounds and the choice of an appropriate pharmaceutical form could guarantee the dose accuracy and facilitate the administration of the active substance and acceptance to treatment. Thus, soluble tea powder is an interesting proposal for a quick, practical and standardized product, when compared to the homemade preparation of herbal drugs. This study aims to develop and compare two formulations of soluble tea obtained by lyophilization and atomization from mangaba fruit, in terms of antihypertensive and antidiabetic potentials and sensory acceptance.
