Essential Components from Plant Source Oils: A Review on Extraction
The average antioxidant activity in peanut oils is 0.81 mg/100 g and the average inhibition percentage is 18%. Eight different fatty acids make up the majority of the triglycerides in peanut oil. Oleic acid (monounsaturated, C18:1) and linoleic acid (polyunsaturated, C18:2) make up around 81% of these fatty acids .
In summary, lipid profile of peanut oils extracted from raw, light, and dark roasted peanut kernels were investigated and compared based on lipidomic approach. Our findings revealed that roasting significantly affected lipid profile, especially fatty acids, phospholipids, and oxidized fatty acids in peanut oils.
Effect of storage on the quality of peanut grain oil
The fatty acid profiles of the oils extracted from peanut grains are shown in Fig. 6. During storage, regardless of temperature and processing, the extract demonstrated an average reduction of 8 % for stearic and palmitic acids. On the other hand, oleic and linoleic acids increased during storage by 6.5 % and 20 %, respectively.
How and Young (1983), Dwivedi et al. (2000), Ozcan and Seven (2003) and Wang and Xu (2013) indicated that fatty acid composition of peanut oils has been studied in different cultivars by some
Fatty Acid Profiles of Some Nut Oils Harvested at The - Springer
The fatty acid compositions of nut oils extracted from pine stone, peanut and pistachio collected at the different harvest periods were analysed. Oil content of nut shown increased at high level from harvest 1 to harvest 2 periods. The major fatty acids of samples were palmitic, stearic, oleic, linoleic acids. While palmitic acid contents of pistachio nut change between 14.08% to 8.70%; peanut
Oleic acid was the most abundant fatty acid in peanuts, accounting for 40.70 % of total fatty acid content. Linoleic acid is a polyunsaturated fatty acid that is essential for the body’s life activities and cannot be synthesized by the body. Linoleic acid content in peanut crude OBs was approximately 35.01 %.
Improving oxidative stability of peanut oil under microwave treatment
The resulting emulsion was frozen rapidly in liquid nitrogen, and lyophilized using a freeze-drying machine for 48 h. Finally, all of the stearic acid–surfactant–tea polyphenols complexes (SSTC) were obtained. The SSTC was dispersed in peanut oil. Oxidation products of the oil sample were analyzed by GC–MS under microwave heating.
Among the SFA, lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) are the most abundant compounds in both fats and oils. Lauric acid less abundant in animal fats and only present in butterfat with 3% of total fatty acids reached high percentages in coconut and palm kernel oil (47% and 48% of total fatty acids, respectively) [ 39 ].
- Why is US pretreatment used in the extraction of peanut oil & proteins?
- US pretreatment technique can be applied for the extraction of peanut oil and proteins to improve their heat-induced gelation properties by modifying their molecular structure to the denser and more homogeneous network (more stable) which is less sensitive to enzyme hydrolysis ( Fig. 13 ).
- Which fatty acids are found in roasted peanut oil?
- Roasted peanut oil obtained via superheated-steam roasting showed higher iodine value and oil viscosity than roasted peanut oil obtained via conventional roasting. The major fatty acids identified in roasted peanut oils obtained via both roasting modes were oleic acid, followed by linoleic, palmitic, lauric, erucic, and stearic acids.
- How is peanut oil extracted?
- Peanut crude oil (100 g), extracted by chloroform-methanol method, was placed in 250 mL-beaker and heated to 80 °C in thermostatically-controlled water bath vibrator, after which 222 ¦ÌL of citric acid (45 %) was added.
- Which enzyme is used in aqueous enzymatic extraction of peanut protein and oil?
- Protease, pectinase, cellulase, and hemicellulase are widely used in aqueous enzymatic extraction of peanut protein and oil. Proteases can substantially improve yield of oil and protein by hydrolyzing peanut proteins into smaller peptides ( Wang et al., 2008; Li et al., 2016 ).
