RESUMO
This research was aimed to study the lipid fraction of date seeds. Seventeen seeds of date palm varieties and clones were evaluated and assessed for their chemical components and for the properties of the date pits oil. Gas liquid chromatography showed that the main unsaturated fatty acid was oleic acid (46.00 - 50.87%), while the main saturated fatty acid was lauric acid (10.11 - 19.03%) for the cultivars Mentouj Tissgharine (MTN) and Bheir Ingli (KBN) respectively; other fatty acids were also identified. The physicochemical characterization showed an acid value ranging from 0.068 to 1.188%, a specific extinction value equal to (K232: 1.350-2.225; K270: 0.318- 0.521), a peroxide value in the interval (1.059-5.618 meq O2/kg) and an iodine value (41.861-59.980 g Iodine/100 g). The pheophytin content of date seed oils was found within the range from 21.855 to 75.685%. The chemical analysis showed that date seed oil can be useful in cosmetic and food products processing.

Fresh dates of seventeen varieties and khalts from Southern Morocco were analysed for their colour, pigments content, and sensory profile. The results showed significant differences between the sensory profiles of the samples due to the variability of the genotype and their different origin. Fresh date varieties and khalts were a good source of ß-carotene (0.49 - 10.86 µg of ß-carotene /100 g FW). The results revealed that the date varieties and khalts were found to have an excellent functional composition and good sensory characteristics. Therefore, these varieties of Moroccan dates could be used for fresh consumption and in the processing industry, which will constitute a significant source of antioxidants.

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.
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.

Hibernomas are rare benign tumours originating from the brown fat found in the foetus and animals that hibernate. In most cases they present as a slowly growing painful mass situated in those regions where this type of fat persists in the adult. We report a case of hibernoma of the forearm, which is an unusual localization, and we review the diagnostic and therapeutic aspects of this of tumour whose main differential diagnosis is liposarcoma.
