Abstract
Vegetable pigeonpea is an important food crop in the dryland regions. In this research, pigeonpea nutrient (zinc, iron, vitamins C and A, total sugar, and protein) was determined at post-harvest following treatment, and 5, 7, 14, 21, and 60 days of storage. Treatments (un-blanched, blanched, oven-dried, blanched + oven-dried, podded) had significant effects (p < .01) on pigeonpea nutrients. Zinc and vitamin C contents were reduced by blanched treatment by 42% and 45%, respectively. After 60 days of storage, pigeonpea in the blanched + oven-dried treatment had the highest iron content (88%), while the podded sample had 20% zinc content due to moisture loss. Treatments resulted in the retention of iron (7.2 mg/100 g), zinc (2.8 mg/100 g), total sugars (4.3 mg/100 g), vitamin A (337.2 µg/100 g), and protein (23 g/100 g) in threshed pigeonpea and vitamin C (28 mg/100 g) in podded pea at 60 days of storage. Optimum nutrient content was recorded at 14–21 days of storage. Impact statement As a food security crop grown in the dry regions where nutrient deficiency is rampant, enhanced nutrient retention in pigeonpea can optimize its utilization. Post-harvest treatments had significant effects on retention of iron, zinc, total sugars, vitamin A, protein, and vitamin C were recorded at 60 days of storage. Increased utilization of pigeonpea will enhance food security for farmers.
