Molecular Finger Printing of Nutra-Coconut Oil with Improved Health Protective Phytoceuticals and its Efficacy as Frying Medium

Coconut oil is rich in medium chain triglycerides but lacks polyunsaturated fatty acids (PUFA) and bio-active phytoceuticals. In the present work nutra -coconut oil was prepared by blending coconut oil and flaxseed oil (70:30) and adding 3000 ppm of flaxseed cake concentrate using ethanol, methanol and 20 % aqueous ethanol. The concentrate prepared from flaxseed was from ethanol as it gave maximum yield. The different bio-active molecules in flaxseed concentrate observed are polyphenols (39.04 %), tocopherols (4.37 %), ferulic acid (0.17 mg g −1 ), p-coumaric acid (2.24 mg g −1 ), chlorogenic acid (16.11 mg g −1 ), gallic acid (8.58 mg g −1 ), sinapic acid (0.64 mg g −1 ) and secoisolariresinol (30.13 mg g −1 ). The nutra -coconut oil was found to have polyphenols (2.86 %), tocopherols (442.96 ppm) and antiradical activity (94 %). The PUFA content was found to increase in nutra -coconut oil significantly ( p 0.05) difference observed in sensory attributes of snack food fried using coconut oil and nutra -coconut oil indicating that the later could be used as a frying medium and useful for food processing industries.
