Biochemical Compositions and Antinutritional Factors of <i>Parinari Curatellifolia</i> Planch. Ex Benth (Chrysobalanaceae) Seeds Kernel

Study was conducted on nutritional value to complete information on chemical and Physico-chemical properties of Parinari curatellifolia, seeds and seed oils to better use. The proximate composition and crude fibers of the seed was determined using AOAC standard methods. Mineral and amino acid compositions were determined respectively by gas chromatography, HPLC, inductively coupled plasma atomic emission spectrometry (ICP-AES) and liquid chromatography coupled to a tandem mass spectrometer (LC-MS/MS). Simple sugars, phytate and plolyphenol were detetermined. The seeds were characterized by high crude oil (38.5%) and protein contents (27.2%). Physico-chemical properties of seed oils showed low acid value (0.33 mg of KOH/g of oil) and oxidative stability index and high iodine and peroxide value due to the high level of unsaturated fatty acids (85,8%). Potassium was the major mineral (629.866 mg/100g) followed by phosphorus (484.784 mg/100 g), magnesium (360.934 mg/100 g) and calcium (221.868 mg/100 g). The essential amino acids content was 705505.04 mg/kg corresponded to 84.04% of total amino acid. The seeds contain all essential amino acids except tryptophan. Cysteine (76.52%) was the major amino acid. α-D-glucose content was the higher one with a concentration of 7815.20 mg/kg followed by α-D-galactose (2893.13 mg/kg) and aldehyde-L-arabinose (2576.47 mg/kg). The phytate and polyphenol content were 20.39±0.02 g/kg and 0.10±0.001%, respectively. The results of the present study showed that P. curatellifolia seed kernel had good nutritional value and could be a good source of nutriments requirements in human nutrition and dietetics.
