The aim of the present study is to determine the physicochemical properties of Picroside-II, a phytochemical obtained from the herb of Picrorhiza kurroa. The solubility study of picroside-II shows that it has better solubility in water up to 2.46 mg/mL than organic solvents. The solubility of picroside-II in linseed oil was found to be 71.46 mg/mL. The solubility of Picroside-II in surfactant like Transcutol P and labrasol was found to be 907.80 and 535.90 mg/mL, respectively. Picroside-II had a melting point in the range of 130 to 135°C. The log P value of picroside-II was estimated using shake flask method followed by UV analysis. The log P value of picroside-II was found to be -0.09675, which shows its hydrophilicity. The pKa determination of picroside-II was carried out by using UV-visible spectrophotometer and the pKa value was found to be 7.80. The particle size distribution of picroside-II powder was also carried out and the maximum particles of picroside-II are in the range of 53-75 μm. Flow properties of picroside-II were also studied. bulk and tapped density of picroside-II powder was found to be 0.149 and 0.248, respectively. The Hausner ratio and compressibility index were also calculated and it was found to be 1.66 and 39.99, which confirm the poor flow properities of picroside-II powder. The angle of repose of picroside-II was found to be 41.08°, which shows the passable flow of picroside-II. Water was found to be the better extractive solvent for picroside-II; the extractive value of picroside-II in water was found to be 9.12%.

The storage of lipid foods is mostly affected by the oxidation of lipid fraction. Dry foods are particularly sensitive because lipids are not protected by hydrated proteins against oxidation. A method suitable for testing dry foods was studied in model mixtures of rapeseed oil with albumin or cellulose. Oxipres apparatus was used, where the course of oxidation is monitored by changes of oxygen pressure. The end of induction period was more evident than in bulk oils as the contact of lipids with oxygen is better. The induction period was longer in mixtures of edible oil with albumin than in mixtures with cellulose. The induction period moderately decreased with increasing oxygen pressure, while the effect of sample weight was nearly negligible. The induction period length was a semilogarithmic function of reaction temperature. Variation coefficients and differences between the duplicates showed good reproducibility; they were lower in mixtures with albumin than in mixtures with cellulose, but both were of the same order as the respective values in bulk oils. At 120°C and 0.5 MPa oxygen, the induction periods could be usually measured within a working day.
