Abstract

This study determined the chemical composition of the various parts of the Passiflora edulis fruit. The various parts were separated and analyzed for –chemical composition and antinutrient contents. Calculated were mineral safety index (MSI) and mineral ratios of some minerals; regression analyses in mineral and proximate values between seed/juice and between inner coat/outer coat; the contribution of energy due to fat, carbohydrate and protein to the total energy. The results showed that the most concentrated values were seen as follows: ash (seed), moisture (juice), protein (seed), fat (outer coat), fibre (seed), carbohydrate (seed) juice (vitamin C) and outer coat (vitamin A). Highest total energy was contributed by the seed and the least by the juice. The followings were observed as the most concentrated values: Na (outer coat), K (seed), Ca (seed), Mg (seed), Zn (outer coat), Fe (outer coat), Cu (seed), Mn (outer coat), Co (juice) and P (seed). No mineral met the ideal ratio as they were either too low or too high from the ideal. No mineral had deleterious value in the MSI. All the sugar were of low levels except maltose was greater than 1.0 in the inner coat. The rc were greater than rr in proximate composition (only in inner coat/outer coat), (both in seed/juice and inner coat/outer coat) but rr were less than rr (seed/juice only) and in sugar content (inner coat/outer coat).
