  • 摘要:In Nigeria, okra Abelmoschus esculentus are packed and stored in polypropylene bag when moved from outlying villages to the city market. The study aims at assessing other storage method for Benin indigenous okra other than polypropylene bag with respect to nutrients, antinutrients and antioxidants. In this study fresh harvested Benin okra were harvested and divided into three parts. One part was stored in 100% RH at the temperature of 10°C ± 2°C, another at the temperature of 10°C ± 2°C and the last part in polypropylene bag. The nutrients, antinutrients (Phytate and Saponin) antioxidants (Vitamin C and Total Phenol) and the Viscosity were subsequently determined. The result of the study indicates that the nutrient, antinutrient and antioxidant content reduces significantly (p>0.05) in the three storage methods: Moisture (88.73-84.62)%, fibre (10.63-7.22)%, protein (14.87-12.84)%, fat (9.67-7.96)%, phytate (3.84-1.18)%, saponin (0.612-0.284)%, vitamin C (46.28-14.39) mg/100g, total phenol (0.095-0.059)% and the viscosity (58.16-53.42)cp. The method of storage of 100%RH recorded the least percentage loss in moisture, fibre antioxidant and viscosity content of the okra while the least % loss was recorded for protein and fat in the polypropylene bag method. The highest loss of the antinutrient was recorded at the storage method of temperature of 10°C ± 2°C. On the average the storage method of 100%RH at temperature of 10°C ±2°C shows to be better method than the others.
