Abstract :
<p> <span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">The iron content in fruits in present study was determined by converting the iron to ferric form</span><b style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;"> </b><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">using saturated solution of oxidizing agent, potassium per sulphate solution (K</span><sub style="font-family: "Times New Roman", serif; text-align: justify;">2</sub><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">S</span><sub style="font-family: "Times New Roman", serif; text-align: justify;">2</sub><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">O</span><sub style="font-family: "Times New Roman", serif; text-align: justify;">8</sub><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">). The resulting ferric form of iron is then made to react with reagent solution of potassium thiocyanate (KSCN) having high concentration (3N) in presence of strong acid to form red coloured ferric thiocyanate complex, having formula [Fe(SCN)</span><sub style="font-family: "Times New Roman", serif; text-align: justify;">6</sub><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">]</span><sup style="font-family: "Times New Roman", serif; text-align: justify;">3-</sup><span style="font-family: "Times New Roman", serif; font-size: 12pt; text-align: justify;">. The concentration of iron (mg/100g) present in fruit samples under study is determined colorimetrically by measuring the absorbance of iron thiocyanate sample complex at 480 nm against reagent blank iron thiocyanate standard complex. The present work is carried out for Eugenia Jambolina and cordia sebastina rare fruits seasonally grown in Latur Dist. </span></p> <p class="MsoNormal" style="text-align:justify"><span style="font-size:12.0pt; line-height:115%;font-family:"Times New Roman",serif"><o:p></o:p></span></p>
