Nutritional and antinutritional profiling of Indian elephant foot yam [(Amorphophallus paeoniifolius (Dennst.) Nicolson)] genotypes
摘要
Eighteen elephant foot yam genotypes were analysed for biochemical parameters, were found starch concentration and protein content ranged from 13.90 to 17.89% and 1.08 to 1.95% respectively while more than 30% of the genotypes had protein contents greater than 1.5%. The genotype named Swagata had the highest starch content (17.89%), highest antioxidant activity (17.45 μg/ml; 50% inhibition), Fe (7.45 mg/100 g), and lowest total oxalate (29.70 ppm). The lowest Ca-oxalate (10.20 ppm), soluble oxalate (10.10 ppm), and HCN (30.10 ppm) containing genotype was found to be Gajendra. It also has the highest energy content (371.82 kJ/100 g). STEFYG-4 had the highest protein content (1.95%), whereas CHEFYG-9-2 had the highest beta carotene concentration (336.00 mcg/100 g). Total oxalate and Ca oxalate showed a positive connection (correlation value = 0.929). Micronutrients like Ca and Mg also showed positive correlation. Principle component analysis (PCA) revealed PC3 described 81.66% of the cumulative variability for antinutrient factors, PC5 explained 79.83% of the cumulative variability in biochemical measures. The highest dry matter (31.57%) containing genotype RJEFYG-5 indicated a comparative highest yield potential.
