摘要

本研究旨在确定辣木种子加工后的近似成分、矿物质含量、吸水能力、能量值和微生物负荷。该研究采用标准的物理化学和微生物学技术进行。结果表明,油籽粉富含蛋白质(34.39%)和脂肪(37.76%),平均粗纤维、灰分和碳水化合物含量分别为5.93%和9.42%,水分含量相对较低,为7.40%,吸水能力、总能量和代谢能水平分别为428.01%、509.67 Kcal/100g和398.22 Kcal/100k。重金属含量较低,可忽略不计,但钙和磷含量较高,分别为437.85 mg/kg和525.10 mg/kg,比例为0.834。总异养细菌和总真菌的计数分别为1730CFU/g和121CFU/g。获得的真菌和细菌为匍匐根霉、黑曲霉、芽孢杆菌、金黄色葡萄球菌、铜绿假单胞菌、变形菌和黄微球菌。没有大肠菌群的记录。这项研究的结果表明,油籽粉是能量、蛋白质、脂肪、钙和磷以及其他矿物质和营养素的良好来源。其营养和矿物质含量支持混凝/絮凝,并用于畜牧和水产养殖饲料。

Nutritional, Functional and Microbiological Analysis of Powdered Seed of Moringa oleifera
This study looked to establish the proximate composition, mineral content, water absorption capacity, energy values and microbial load of the seeds of Moringa oleifera following processing. The study was carried out using standard physicochemical and microbiological techniques. Proximate analysis revealed that M. oleifera seed powder was rich in protein (34.39%) and fat (37.76%). The mean crude fibre, ash and carbohydrate values were 5.93% and 9.42% respectively while moisture was relatively low at 7.40%. The water absorption capacity, gross energy and metabolisable energy levels were determined as 428.01%, 509.67 Kcal/100g and 398.22 Kcal/100g respectively. The heavy metal levels were low to negligible but the calcium and phosphorus levels were somewhat high at 437.85 mg/kg and 525.10 mg/kg respectively with a ratio of 0.834. Counts of 1730 CFU/g and 121 CFU/g were obtained for total heterotrophic bacteria and total fungi. The fungi and bacteria obtained were Rhizopus stolonifer , Aspergillus niger , Bacillus , Staphylococcus aureus , Pseudomonas aeruginosa , Proteus and Micrococcus luteus . No coliforms were recorded. The results from this study established M. oleifera seed powder as a good source of energy, protein, fat, calcium and phosphorus amongst other minerals and nutrients. Its nutritional and mineral content support coagulation/ flocculation and use in livestock and aquaculture feed.
