Abstract

Coconut oil is rich in medium chain triglycerides but lacks polyunsaturated fatty acids (PUFA) and bioactive 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) (2–22 %). The FT-IR spectra of nutracoconut oil revealed that the peak at 3009 and 1651 cm−1 was associated with the presence of unsaturated fatty acids. There was no significant (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.
