In this study, aqueous enzymatic extraction (AEE) was evaluated during the process of obtaining oil from mamey sapote seed (OMSS). Viscozyme L enzyme complex was used at pH 4 and 50 °C during the optimization of the extraction process by central composite design and response surface methodology. Optimal conditions were: 3.5% (w/w) of enzyme (regarding the seed weight), 5.5 h of incubation time, 235 rpm of agitation rate, and 1:3.5 of solid-to-liquid ratio. These conditions enabled us to obtain an OMSS yield of 66%. No statistically significant differences were found in the fatty acid profile and physicochemical properties, such as the acid and iodine values and the percentage of free fatty acids, between the oil obtained by AEE or by the conventional solvent extraction (SE). However, the oxidative stability of the oil obtained by AEE (11 h) was higher than that obtained by SE (9.33 h), therefore, AEE, in addition to being an environmentally friendly method, produces a superior quality oil in terms of oxidative stability. Finally, the high oil content in mamey sapote seed, and the high percentage of oleic acid (around 50% of the total fatty acid) found in this oil, make it a useful edible vegetable oil.

Aqueous Enzymatic Extraction

The development of a sustainable product using natural resources will gain much attention nowadays. This work aimed to study the effect of aqueous enzymatic extraction (AEE) using a different ratio of enzyme cocktails HEL1 and X7 towards the production of Momordica charantia L. (M. charantia) seed oil and to identify the composition of the seeds’ lignocellulosic biomass (extracted-free materials, EFM). The M. charantia seed oil contained omega-3 fatty acids, such as stearidonic acid, that possess hypotriglyceridemic properties. The oil obtained was derivatized to fatty acid methyl esters (FAMEs) before biochemical quantification using gas chromatography (GC). The EFM was subjected to Soxhlet extraction and further analyzed to identify lignin, acid-soluble sugars, and hemicellulose composition. The results showed that the highest seed oil percentage, (6.26±0.53 %) was extracted from M2 sample using a combination of 5 % HEL1 to 1.25 % X7 enzyme cocktails, as compared to the extraction without enzyme (3.32±0.38 %). The percentage of stearidonic acid in the seed oil increased from 13.55 % (without enzyme) to 19.43 % (M2), proving that there were some change in terms of fatty acid composition in the seed oil.

Antioxidant Power

Pumpkin seed oil is a by-product, abundant in nutrients and bioactive components that promote several health benefits. This study aimed to compare chemical compositions, antioxidant, and pharmacological activities of pumpkin seed oils extracted from Cucurbita moschata Duch. Ex Poir. (PSO1) and Cucurbita moschata (Japanese pumpkin) (PSO2) by aqueous enzymatic extraction. An enzyme mixture consisting of pectinase, cellulase, and protease (1:1:1) was used in the enzymatic extraction process. Fatty acid composition of the oils was determined using fatty acid methyl ester/gas chromatographic-mass spectrometry. Antioxidant activity assays were measured by using stable free radical diphenylpicrylhydrazyl, radical cation 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonate, ferric reducing/antioxidant power, and ferric thiocyanate assay. Inhibition of enzymes involving skin aging and whitening process was investigated. Linoleic acid was a major component of all pumpkin seed oils. Additionally, there was also a significant amount of oleic acid, palmitic acid, and stearic acid detected. PSO2 possessed the highest antioxidant activities compared to PSO1 and commercial pumpkin seed oils (COM1 and COM2). Both PSO1 and PSO2 exhibited higher inhibitory effects on hyaluronidase, collagenase, and tyrosinase than the commercials. Therefore, aqueous enzymatic extraction could yield pumpkin seed oils with higher antioxidant, anti-aging, and whitening activities. This is beneficial for further pharmacological studies and can be used as a functional food for skin benefits.

Abstract The oil and protein of dehulled cold-pressed double-low rapeseed cake was extracted by an aqueous enzymatic process. The rapeseed cake was treated by the chosen combined enzymes of Viscozyme L and Alcalase 2.4L (VLA,1:1,w/w). Preliminary experiments and Response Surface Methodology (RSM) were used to study the effects of enzyme concentration, incubation time and water-to-cake ratio on the extraction yield of oil and protein. This is how the desirable conditions were obtained. Transmissive electron microscope photo showed that after cold-pressing the cell structure of rapeseed was partly damaged while dehulling had little effect on the cell structure of rapeseed. In RSM experiments water-to-cake ratio showed significant effects on the extraction of oil and protein (P<0.05),while incubation time only showed significant effects on protein yield (P<0.05).The desirable conditions were as follows: 1.0% concentration (w/w) of VLA; water-to-cake ratio(w/w),6:1; 80 min incubation time. Under this condition, the extraction yield of protein and oil were 82.10% and 71.89%, respectively. Through combining both the cold-press and the aqueous enzymatic processes together, the total oil yield reached 91.6%, which is higher than the normal cold-press process or the aqueous enzymatic extraction process alone.

This paper investigated the effects of Prunus pedunculatus (P. pedunculatus) seed pre-treatment, including microwaving (M), roasting (R), steaming (S) and roasting plus steaming (RS) on crude oil quality in terms of yield, color change, fatty acid composition, and oxidative stability. The results showed an increase in monounsaturated fatty acid content and oxidative stability of the oils obtained from different processing treatments compared to the oil obtained from raw seeds (RW) without processing. The oils, obtained from pretreated seeds, had higher conjugated diene (CD) and 2-thiobarbituric acid (2-TBA) values, compared to that obtained from RW when stored in a Schaal oven at 65 °C for 168 h. However, polyphenol and tocopherol contents decreased in all oil samples, processed or unprocessed. The effect of pre-treating the seeds was more prominent in the oil sample obtained through the RS technique, and showed higher oxidative stability than the other processed oils and the oil from RW.

The aim of this study was to determine the chemical composition (fatty acids, tocopherols, and sterols) and evaluate the oxidative stability of Moroccan pomegranate (Punica granatum L.) seed oil. The oil content of pomegranate seed was 22.63 g/100g of dry weight. The fatty acid composition showed a dominance of conjugated linolenic acids (CLnAs) (86.96 g/100g). The most dominant fatty acid was punicic acid (75.1 g/100g), followed by catalpic acid (6.7 g/100g) and linoleic acid with amounts of 4.11 g/100g. The seed oil only contained a low level of saturated fatty acids with palmitic (2.64 g/100g) and stearic acids (1.73 g/100g) as main saturated fatty acids. The sterol marker, β-sitosterol, accounted for 404.59 mg/100g of the total sterol content in the seed oil. Total tocopherol content in seed oil was 332.44 mg/100g. γ-tocopherol (190.47 mg/100g oil) is the major constituent, followed by α-tocopherol (74.62 mg/100g oil) and δ-tocopherol (53.3 mg/100g oil). The induction time calculated by the Rancimat accelerated method was found to be of 3.6 h at 120 °C. In terms of oil, pomegranate seed oil may be considered as a valuable source for new multipurpose products with industrial, cosmetic and pharmaceutical uses.
