Chemical characterization of seeds and seed oils from mature Terminalia catappa fruits harvested in C?te d’Ivoire

摘要

The seeds of mature Terminalia catappa ripe (MTCRF) and unripe fruits (MTCUF) from C.te d'Ivoire were analysed for their main chemical compositions. Studies were also conducted on properties of oils extracted from the same seeds. The following values (on a dry-weight basis) were obtained for seeds of MTCUF and MTCRF, respectively: moisture 5.10 ± 0.75 and 4.80 ± 0.34%, crude protein 29.77 ± 1.12 and 29.89 ± 0.41%, oil 58.61 ± 0.13and 63.65 ± 0.04%, total sugars 3.02 ± 0.05 and 3.53 ± 0.10%, reducing sugars 0.08 ± 0.01and 0.06 ± 0.01%, total carbohydrate 5.38 ± 0.02and 5.09 ± 0.12 %, total ash 5.10 ± 0.20and 4.60 ± 0.14% and calorific value 573.79 ± 1.02and 567.75 ± 0.84kcal/100 g. Within these seeds, the potassium concentration was the highest, followed by phosphorus and calcium. T he major saturated fatty acid was palmitic acid, while the main unsaturated fatty acid was oleic acid for the MTCRF and linoleic acid for the MTCUF seed oils. These seed oils had characteristically low acidity and peroxide values and showed some absorbance in the UV-B and UV-C ranges. MTCUF and MTCRF seeds and seed oils originated from C.te d'Ivoire were a good quality and could be used in cosmetic, pharmaceutical and food products
