The seed oils have been characterized for the nutritional and functional importance but its industrial extraction process is not yet adequately studied. The present investigation was done to optimize the pre soaking time in solvent (hexane) and extraction time in solvent extraction method to extract the oil from wood apple seed. The pre soaking time and extraction time ranged from 2 h to 10 h and was optimized using Central Composite Rotatable Design (CCRD) and the second order quadratic polynomial regression equation model. At linear and quadratic level, the pre-soaking time revealed a significant influence on oil recovery at p<0.01. The magnitude of influence of pre soaking time on oil recovery from wood apple seed was greater than extraction time. The predicted R2 of 0.7512 was in reasonable agreement with the adjusted R2 of 0.9424. Adequate precision ratio of 22.526 indicated an adequate signal for the proposed model. According to numerical and graphical optimization, the wood apple seed could be pre soaked in solvent (hexane) for 8 hours and extracted for 8 hours in Soxhlet method of extraction to get maximum oil recovery of 32.99%. The actual oil recovery at optimum point prediction of independent variables was significantly (p<0.01) agreed with the predicted oil recovery.Keywords

Drying is a thermo-physical and physico chemical operation by which it removes water from food material at appropriate temperature and most suitable rate to retain maximum food values. Drying is one of the simplest and best methods of preservation of foods, because it reduces the cost of storage and transport by reducing both weight and volume of final product.- Quality Evaluation of Chapati from Millet Flour Blend Incorporated Composite Flour

Diabetes mellitus is one of the most common problems challenging physicians in the 21st century. It is also called as "Ice Berg" disease. World Health Organization stresses that India will have the greatest magnitude of increase, approximately 170 per cent by the year 2025 AD. Within the allotted span, India shall also have the dubious distinction of having the maximum number of diabetics in the world. To note, most of these diabetic individuals in India shall be in the most productive years of their lives. More than 90 per cent of the diabetic patients in India are suffering from type II diabetes.- Prevalence of Thyroid Disorders and Iodine Status among Adult Women in Thindal Area of Erode District
