COMPOSIÇÃO QUÍMICA DA LARANJA KINKAN E DE FRUTAS CÍTRICAS

Abstract

Kinkan orange (Fortunella margarita), commonly known as“golden orange”, is originally from Asia and belongs to the genusFortunella. Kinkan orange has some characteristics of citrusfruits, which are the most consumed fruits by the Brazilianpopulation. Objective: The study aimed to evaluate the chemicalcharacterization of kinkan orange by comparing the resultsobtained with data published on the analysis of some citrus fruitsof great commercial interest in Brazil, such as serra-d’água orange,pera-rio orange, ponkan tangerine and tahiti lime. Methodology:We evaluated pH, soluble solids, titratable acidity, and contentof vitamin C, total phenolics and antioxidant capacity. All testswere performed in triplicate and data were compared by Tukey’stest (p <0.05). Results: Kinkan orange had the highest content ofsoluble solids (SS) and low titratable acidity (TA), consequentlya high SS / TA ratio, high vitamin C content and the highestcontent of total phenolics compared to other fruits. Conclusion:Kinkan orange has chemical characteristics similar to other citrusfruits such as pH, titratable acidity and content of vitamin C, hasexcellent palatability and can be considered as a source of totalphenolic and vitamin C in the diet.
