Rancidity, acidity index, saponification number, density and humidity test were determined using the corresponding Mexican standard guidelines (NMX-F-222-SCFI-1995, NMX-F-075-SCFI-2006, NMX-F-174-SCFI-2006, NMX-F-211-SCFI-2006, NMX-F-101-SCFI-2012), while the peroxide number was determined in compliance with AOAC (2000).
The saponification number (X) in of KOH/g product was calculated by the formula: X = ([V.sub.0] - V) x K x 5.6/m, where [V.sub.0] and V are the volumes of the hydrochloric acid solution consumed for titration in the blank test and the sample of the product, respectively.

Saponification number was found to be 195 mg KOH/g oil and resembled that of honeydew melon (210 mg KOH/g oil) which was also a variety of Cucumis melo found by (Yanty et al., 2008).
Tenders are invited for 12-hydroxystearic acid CAS 106-14-9 country of origin - India, an acid number of 175-185 mg KOH / g, a saponification number of 180-190 mg KOH / g, the content of 12-hydroxystearic acid is not less than 83%.
This dried product contained hydroxylated oligomer and unreacted PET (low molecular weight) which were then separated by the procedure as described in our earlier study [19] and characterized for determination of saponification number, hydroxyl value as per ASTM methods and for molecular weight by GPC technique.
