EFFECTS OF SOME SALTS (Nacl and Na2 SO4) ON FUNCTIONAL PROPERTIES OF PUMPKIN SEED (TELFARIA OCCIDENTALS) FLOOR.

ABSTRACT

A study was carried out on the physico – chemical properties of fluted pumpkin seeds (Telferia occidentalis) flours. The 1st two flour samples were obtained by boiling for 1 hr in 0.5% solution for Nacl, and .5% solution of Na2 S04 respectively.

The 2nd two samples were obtained by soaking for 12 hrs in 0.5% soln of Nacl, and 0.5% soln of Na2 So4 respectively. The control was neither soaked; F4, F6, F5, F7, and F8 respectively. All the samples were dried milled and sieved to obtain their respectively flours. The flour samples were defatted using n-hexane. Proximate composition, Protein solubility and foaming capacity of the samples were determined result showed that the flours contain moisture (1 040-14.67%)

Ash (5.72 – 10.72%) crude fat (6.22-11.17%) crude fibre (4.89 –6.78%) crude protein (59.20 –69.83%). Protein solubility and from capacity of the samples were affected by treatment employed.

Protein solubility ranged between (35 . 57 – 47. 27) while foam capacity varied at different pH values.
