“…The oil has also been used in manufacturing of lubricants, perfume, medicine, skincare products, biodiesel feedstock, and so on (Dou and Kister, ; Mahmood et al, ; Patel et al, ; Silva et al, ). The biologically active substances identified include tocopherols, sterols, carotenoids, and polyphenolic compounds, which help in scavenging free radicals (Fotouom et al, ; Saini et al, ). Other workers have shown that the seed oil of the plant is rich in tocopherol (Qi et al, ).…”

This work focused on physicochemical property assaying, fatty acid composition, triacylglycerol (TAG) profiles, and unsaponifiable matter composition of the Chinese Moringa oleifera seed oil. The results indicated that there was no significant difference in approximate nutritional components between M. oleifera seeds from China and India, while variations in the mineral element contents are significant. Both the Soxhlet extraction method and the aqueous enzymatic extraction method were adopted to extract oil from Chinese M. oleifera seeds. Oil yield obtained using the Soxhlet extraction method was higher than that obtained using the aqueous enzymatic extraction method. While both the iodine value and unsaponifiable matter content of the aqueous enzymatic extracted oil were a little higher than that of the Soxhlet extracted oil. Both oils possess a very low acid value and peroxide value, suggesting their good quality as edible oil. Fatty acid composition results indicated that this oil was especially high in oleic acid. Characterization of the TAG composition was achieved by a two-dimensional high-performance liquid chromatography (HPLC) coupling of nonaqueous reverse-phase and silver ion HPLC with the atmospheric pressure chemical ionization mass spectrometry method. A total of 22 TAG including 16 regioisomers were determined. Composition results of unsaponifiable matters revealed that this oil possesses a number of phytosterols, in which β-sitosterol and stigmasterol are most predominant.Keywords Moringa oleifera seed oil Á Physicochemical property Á Triacylglycerol Á Unsaponifiable matter J Am Oil Chem Soc (2019) 96: 523-533.

“…Moringa oleifera oil is known to have very high amounts of oleic acid (70%), palmitic acid, stearic acid, behenic acid, quercetin, luteolin and tocopherols (Martins et al, 2016;Mat Yusoff et al, 2016;Omotoso et al, 2018). The oil can be used as cooking oil, in treatment of arthritis, rheumatism, hypertension, also in cosmetic industry as an emulsifier (Bhutada et al, 2016;Fotouo-M. et al, 2016;Martins et al, 2016). The oxidative stability of Moringa oleifera oil is higher than canola oil, palm oil and soybean oil in terms of using as frying oil (Martins et al, 2016;Mat Yusoff et al, 2016;Omotoso et al, 2018).…”

Some physicochemical characteristics and fatty acid composition of Moringa seed oil was analyzed. The seed oil was obtained by cold press. Moringa seed contains 4.92% moisture, 42.15% fat, 35.54% protein, 2.98% ash, 8.44% dietary fiber and 14.41% carbohydrate in the dry matter. Oleic acid was the main fatty acid (74.29%) and it was followed by behenic acid (6.09%), palmitic acid (5.83%), stearic acid (4.67%), arachidic acid (3.32%) and gadoleic acid (2.37%), respectively. Moringa oil had a total saturated fatty acid (SFA) content of about 21.39% and a total unsaturated fatty acid (TUFA) content of about 78.58%. Total antioxidant and total phenolic substance amounts were 22.28 mM Trolox/ml and 455.33 mg gallic acid/g, respectively. The moringa seed has very high fat and protein contents and the fatty acid composition indicates that the seed oil of Moringa oleifera is included in high-oleic oils category, and has a high MUFA/SFA ratio.

“…Fotouo et al . (2016) demonstrated the effect of the storage of MO seeds on the quantity and quality of the MO oil for its potential in biodiesel production. However, the effect of the storage of MO oil at different temperatures on its quality attributes had never been reported, which is of great importance in determining the shelf life of the oil.…”

Oxidative properties of Moringa oleifera kernel oil from different extraction methods during storage

et al. 2019

BACKGROUND: Moringa oleifera (MO) kernel oil is categorized as a high-oleic oil that resembles olive oil. However, unlike olive trees, MO trees are largely present in most subtropical and tropical countries. In these countries, therefore, the benefits of oleic acid can be obtained at a cheaper price through the consumption of MO kernel oil. This study reports on the effect of different extraction methods on oxidative properties of MO kernel oil during storage for 140 days at 13, 25, and 37 ∘ C. RESULTS: All aqueous enzymatic extraction (AEE)-based methods generally resulted in oil with better oxidative properties and higher tocopherol retention than the use of solvent. Prior to AEE, boiling pre-treatment deactivated the hydrolytic enzymes and preserved the oil's quality. In contrast, high-pressure processing (HPP) pre-treatment accelerated hydrolytic reaction and resulted in an increase in free fatty acids after 140 days at all temperatures. No significant changes were detected in the oils' iodine values and fatty acid composition. The tocopherol content decreased significantly at both 13 and 25 ∘ C after 60 days in the oil from SE method, and after 120 days in oils from AEE-based methods.CONCLUSION: These findings are significant in highlighting the extraction methods resulting in crude MO kernel oil with greatest oxidative stability in the storage conditions tested. Subsequently, the suitable storage condition of the oil prior to refining can be determined. Further studies are recommended in determining the suitable refining processes and parameters for the MO kernel oil prior to application in variety food products. Aqueous enzymatic extraction with high pressure processing pre-treatment (HPP-AEE)The ground-sieved MO kernels were mixed with distilled water at a 1:1 (w/w) ratio and vacuum sealed in polyethylene bags. According to Mat Yusoff et al. (2017), 21 some preliminary tests were carried out to determine the solid-to-liquid ratio. The use of a smaller amount of water caused the formation of a very thick paste, which adhered to the polyester bag, thus wasting some of the sample. The addition of a higher water content resulted in a very dilute mixture, which thus allowed only a small amount of ground-sieved MO kernel to be processed at one time.The mixtures at 1:1 (w/w) ratio were treated with high pressure (Stansted Fluid Powder Ltd, Stansted, UK) at 50 MPa and 60 ∘ C for 35 min, followed by addition of distilled water up to 4:1 water / kernel (w/w) ratio for the subsequent AEE, as in the earlier section. The recovery of the free oil is explained in the next section.
