ABSTRACT
Date fruit is known to be the staple food in the Arab countries. It provides a lot of potential health benefits and can be the essential source of nutrients. The majority of Moroccan varieties are not characterized for their chemical, biochemical and quality properties. The aim of this work was to assess the chemical composition of 17 varieties of Moroccan date fruits (Phoenix dactylifera L.) and to determine their nutritive components. The analysis showed that the dates are rich in sugars (51.80-87.98%), they contain low concentration of proteins (1.09-2.80%) and lipids (0.16-0.39%). The predominant mineral is potassium (1055.26-1604.10 mg/100 g DW). Moreover, they contain high concentrations of malic acid (69.48-495.58 mg/100 g (DW)), oxalic acid (18.47-233.35 mg/100 g DW) and tartaric acid (115.70-484.168 mg/100 g DW). These results suggest that the date fruit are nutritious and can be an excellent source for human nutrition and health benefits.
RESUMO
A fruta da tâmara é conhecida por ser o alimento básico nos países árabes. Oferece muitos benefícios potenciais à saúde e pode ser a fonte essencial de nutrientes. A maioria das variedades marroquinas não se caracteriza por suas propriedades químicas, bioquímicas nem de qualidade. O objetivo deste trabalho foi avaliar a composição química de 17 variedades de frutos de tâmara marroquina (Phoenix dactylifera L.) e determinar seu valor nutritivo. A análise mostrou que as tâmaras são ricas em açúcares (51,80-87,98%) e contêm baixa concentração de proteínas (1,09-2,80%) e lipídios (0,16-0,39%). O mineral predominante é o potássio (1.055,26-1.604,10 mg/100 g DW). Além disso, contêm altas concentrações de ácido málico (69,48-495,58 mg/100 g DW), ácido oxálico (18,47-233,35 mg/100 g DW) e ácido tartárico (115,70-484,168 mg/100 g DW). Esses resultados sugerem que o fruto da tamareira é nutritivo e pode ser uma excelente fonte de nutrição humana e conferir benefícios à saúde.
