The goal of this research was to attempt to evaluate the enzymatic aqueous extraction (EAE) of Mango seed oil compared with standard hexan method. Physicochemical properties and oxidative stability of extracted oil were investigated. So the solvent is safe and does not offer the danger of a lightning strike, the EAE is preferable to solvent extraction procedures. Viscozyme L, Celluclast 1.5 L, Nutrase 0.8L, and Alcalase 2.4l FG enzymes were assayed. The oil extraction yield was improved by using ternary enzyme mixes, although it was still considerably (p0.05) lower than that achieved with hexane . Furthermore, The most common types of enzymes employed for EAE are cellulases, proteases, and pectinases. In comparison to those extracted with hexane, oils extracted using (65:25:10 % from Alcalase : Neutrase : Viscozyme) showed a larger buildup of induction time, indicating improved oxidative stability. As a result, we may visualize future industrialization of EAE techniques and promote them as clean technology using this method. The quantity and quality of the extracted mango seed oils compared to hexane extraction for the above-said variables have been researched.

“…Some factors, such as cultivar, ripeness, and processing, influence the acid value of vegetable oil. It was previously reported that enzymatically extracted kolo oil had a higher acid value than organic solvent‐extracted kolo oil, whereas the contrary was true for safou oil, and enzymatic‐extracted kolo oil and safou oil have lower peroxide value than that of hexane extracted oil . Otherwise, the higher acid value of aqueous enzymatic‐extracted camellia seed oil in this experiment may be due to the acidic extraction condition for protease and cellulase.…”

An aqueous enzymatic extraction method was developed to extract oil from camellia seed (Camellia oleifera Abel.). Individual enzymes and combinations of enzymes, pH, the ratio of material to water, reaction time and methods of demulsification were studied. The effects of hexane and aqueous enzymatic extraction on the oil's physicochemical properties (acid value, peroxide value, fatty acid profile, phenolics, and phospholipids content) were compared. The combination of protease/cellulase yielded significantly more oil than did other combinations. Under the optimal reaction conditions, a free oil yield of 82.37% was obtained. Four types of demulsification methods were compared. After demulsification with 20% ethanol (v/v), the highest total free oil yield of 91.38% was achieved. Compared with hexane-extracted oil, aqueous enzymatic-extracted oil was more acidic; had a higher percentage of monounsaturated fatty acid and contents of vitamin E and squalene; and had lower peroxide values, percentage of total saturated fatty acid, polyunsaturated acid, and content of both total phenolics and total phospholipids.Practical applications: The current work will contribute to an efficient enzymatic extraction method for camellia seed oil and help with the develop a method to demulsify the emulsion.

SFE of the oils of two varieties of grape seeds (Victoria and Red Globe) was performed in a flow apparatus at 40C and 250 bar. The effect of the solvent on the extraction yield was studied using CO2 and CO2 modified with ethanol, and the yield of extraction was compared with conventional extraction methods (Bligh and Dyer and Soxhlet using hexane). SC CO2 + ethanol extracted higher lipid amounts from both varieties, compared with SC CO2 extraction. The comparison between SFE and conventional extraction methods showed that the highest extraction yield was obtained with SC CO2 + ethanol (10%, w/w) (14.7 and 11.8% for Red Globe and Victoria grape seeds, respectively), while pure SC CO2 afforded the lowest lipid yields. The fatty acid compositions of the oils obtained by SFE were analyzed. Fractions containing higher proportions of PUFAs were obtained at lower solvent/dry grape seed ratios, while fractions richer in SFAs and MUFAs were obtained at higher solvent/dry grape seed ratios. PRACTICAL APPLICATIONS SFE could fractionate grape seed oil and afford various grades of oil containing different proportions of fatty acids. The highest grape seed lipid yield obtained was with SC CO2 + ethanol, making this solvent a promising and powerful one for grape seed oil extraction, showing a great advantage compared with conventional extraction methods.
