“…Fatty acid compositions of the AEE-and SE-extracted OMSS are shown in Table 4. As can be observed, three saturated fatty acids (SFAs), one monounsaturated fatty acid (MUFA) and one polyunsaturated fatty acid (PUFA) were identified as the main components, and there were no statistically significant differences in the percentages of these fatty acids obtained for the two evaluated extraction methods (with the exception of linoleic acid, which presented a very slight difference, which cannot be considered relevant for the quality of the oil) [64]. As can be seen in Figure 2 and Table 4, the SFAs were palmitic acid C16:0 (8.7-9.6%), stearic acid C18:0 (27.8-28.1%), and arachidic acid C20:0 (0.8%).…”

“…The positive effect of the agitation rate on the oil extraction yield in AEE was the highest among the linear effects. It can be attributed to the fact that this variable is important to maintain a homogeneous reaction medium, a multiphasic system (solid, aqueous, and oily phases), avoiding concentration gradients, and thus enabling the release of the oil [64]. In the case of the amount of enzyme, its positive effect can be attributed to the fact that as the amount of enzyme molecules increases, there will be more interactions with the substrate, that is, greater destruction of the cell wall, and consequently, greater oil release [60,83].…”

“…Several studies have been reported regarding the evaluation of AEE in obtaining oils from various seeds such as tiger nut (Cyperus esculentus L.) [59], sacha inchi (Plukenetia volubilis L.) [60], Jatropha curcas [61], Jicaro [62], pomegranate [63], castor oil [64], Pinus pumila [25], Moringa oleifera [65], Pumpkin (Cucurbita pepo) [50], sunflower [66], soybean [67], almond [49], etc. Although the enzymatic oil extraction has been widely explored, in the reported studies, different oil yields are observed for each seed; this is due to the fact that the composition of the cell wall of the seed, which is quite heterogeneous, is different for each seed, so different enzymes and conditions are necessary in each case.…”

“…Although the enzymatic oil extraction has been widely explored, in the reported studies, different oil yields are observed for each seed; this is due to the fact that the composition of the cell wall of the seed, which is quite heterogeneous, is different for each seed, so different enzymes and conditions are necessary in each case. In addition, AEE results are still lower than that achieved using SE, which limits its use [64,[68][69][70]. In this context, AEE efficiency has been improved by the utilization of technologies like microwave irradiation and ultrasounds [71,72].…”

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.

“…In general, polysaccharide is extracted by hot water, microwave, ultrasound, enzymolysis, supercritical carbon dioxide, or ultra‐high pressure, etc. During the extraction of plant polysaccharides, the permeability of cell membrane and cell wall could be improved by cellulase . In addition, enzymatic extraction is generally regarded as safe and environmentally friendly, it is widely used in the research of polysaccharide extraction.…”

Lenzites betulina has been recognized as a rich source of chemical components, including polysaccharides, sterides and sugar alcohols. In this study, cellulase−ultrasonic synergistic extraction method was applied to extract polysaccharides from L. betulina, and the response surface methodology was used to optimize the extraction conditions. The eight basic factors affecting extraction yield were evaluated by Plackett−Burman design (PBD). Then, the four important factors significantly affecting the yield of polysaccharides from L. betulina, including enzymolysis temperature, enzymolysis time, ultrasound time and ultrasound temperature, were optimized by Box−Behnken design (BBD). Maximum extraction yield of L. betulina polysaccharides was 13.64±0.09 % at a cellulase dosage of 0.8 %, enzymolysis temperature of 60 °C, enzymolysis time of 180 min, pH of 4.5, liquid‐solid ratio of 45 ml/g, ultrasound power of 300 W, ultrasound time of 20 min and ultrasound temperature of 45 °C. Subsequently, the characteristic structure of crude polysaccharides was determined by FT‐IR. Results indicated that cellulase−ultrasonic synergistic treatment is suitable for L. betulina polysaccharides extraction, and it has good prospect for development and utilization.
