Comparison of Cold-Pressing and Soxhlet Extraction Systems for Bioactive Compounds, Antioxidant Properties, Polyphenols, Fatty Acids and Tocopherols in Eight Nut Oils. Journal of Food Science and Technology-Mysore, 55(8), 3163-3173.0022-11550975-8402https://dx.doi.org/10.1007/s13197-018-3244-5https://hdl.handle.net/20.500.12395/36421Antioxidant activities of different nut oils ranged from 11.43 (peanut) to 65.58% (pistachio) in cold pressed oils whereas in case of soxhlet extracted oils they were in the range of 11.32 (hazelnut) to 51.28% (pistachio). beta-Carotene contents of oils obtained by cold pressing and soxhlet extraction changed between 7.53 (almond) and 13.58 A mu g/100 g (pistachio). The highest total phenol contents (2.36 mg gallic acid equivalent/100 g) were observed in pistachio oils obtained by cold press. The oleic acid contents of cold pressed and soxhlet extracted oils were between 19.88 (walnut) and 69.43% (pecan) to 19.07 (walnut) and 68.53% (pecan), respectively. The linoleic acid contents of nut oils from cold press system vary between 12.78 (hazelnut) and 63.56% (walnut), whereas in case of soxhlet extraction, it changed between 11.78 (hazelnut) and 62.41% (walnut). The alpha-tocopherol contents of cold pressed nut oils changed between 0.07 (walnut) and 257.42 mg/kg (hazelnut) alpha-tocopherol contents of nut oils extracted by soxhlet extraction changed between 0.03 (pistachio) and 209.73 mg/kg (hazelnut). The catechin contents of cold pressed nut oils were between 0.56 (cashew) and 3.76 A mu g/100 g (pistachio), whereas that of soxhlet extracted oil varied between 0.64 (cashew) and 3.82 A mu g/100 g (cashew).en10.1007/s13197-018-3244-5info:eu-repo/semantics/openAccessNut oilsCold pressSoxhlet extractionBioactive propertiesFatty acidsTocopherolsPhenolic compoundsArticle5583163317330065427Q1WOS:000438860000037Q2
