“…This study demonstrated that values of TPC and three ACs were significantly different among six extraction methods, and the extraction method of pectinase generally showed the highest values of total polyphenol content, whereas EtOH-2 (an ethanol solvent including a second phase ethanol treatment) showed the lowest values of the parameter for all cultivars (Table 1, Figure 2). In solid-liquid extraction methods, solvents of ethanol, methanol, and acetone are widely applied extraction techniques, e.g., [46]; however, results of previous studies widely differ in the efficacy of extraction methods on the polyphenol content and antioxidant capacity of fruits, e.g., [18,[46][47][48][49]. For instance, the efficiency of water, methanol, and acetone solvents was shown to be significant for the extraction of the soluble polyphenolic compounds [46].…”

“…The good extraction efficiency of a water-ethanol mixture can be explained because ethanol may weaken the bonds between polyphenolics-protein and polyphenolics-cellulose [49]. In addition, the study of Hobbi et al [18] showed that the highest total polyphenol content was measured in a mixture of 65:35 acetone:water (v/v) at 60 • C compared to other unmixed solvents (i.e., water, acetone, and ethanol). Our study confirmed a good yield of polyphenol content using the pectinase extraction method, and using the solvents of ethanol and methanol used alone (Figure 2).…”

“…The main flavonoids measured in apples are anthocyanins, catechins, epicatechins, quercetin glycosides, procyanidins, and phloridzin; and the major phenolic acid compounds of apples are p-coumaroylquinic acid and chlorogenic acid, e.g., [10,13]. Several methodologies are used to measure the antioxidant capacity of plant samples, e.g., [15][16][17][18] and different methods including Ferric Reducing Ability of Plasma (FRAP), 2,2-diphenyl-1-picrylhydrol (DPPH) and Trolox Equivalent Antioxidant Capacity (TEAC) are applied to measure the antioxidant capacity of the apple fruits, e.g., [15,16]. Apples possess a total antioxidant capacity of ca.…”

Polyphenols with antioxidant compounds represent an important group of bioactive substances in apple production. The objectives of this study were firstly to measure four parameters of antioxidant capacity (AC) and polyphenol content (AC-FRAP (Ferric Reducing Ability of Plasma), AC-DPPH (2,2-diphenyl-1-picrylhydrol), AC-TEAC (Trolox Equivalent Antioxidant Capacity) and total polyphenol content (TPC)) of four scab-resistant apple cultivars (‘Fujion’, ‘Gaia’, ‘Isaaq’ and ‘Smeralda’) using six extraction methods (water control, pectinase, two approaches using ethanol (EtOH-1 and EtOH-2), methanol (MetOH) and methanol + acetone (MetOH + Acetone), and secondly to provide intercorrelations between antioxidant and polyphenol contents of the four resistant apple cultivars under the six extraction methods. Analysis of variance on the four parameters showed a significant (p = 0.05) effect for extraction methods and cultivars. TPC showed the highest values among the four parameters in all extraction methods and cultivars compared to the other three measurements. The pectinase extraction method showed the highest TPC values for the four cultivars. The EtOH-2 extraction method showed the lowest AC-FRAP value for all cultivars. The EtOH-2 extraction method showed the highest AC-DPPH values, whereas the control method showed the lowest values for the four cultivars. The AC-TEAC values were generally the lowest, ranging between 10.8 and 40.5 mg TE 100 g−1 dry matter, and they showed various effects on extraction methods and cultivars. Correlation and regression analyses of 36 pair-variables showed that two pair-variables (TPC vs. AC-FRAP and AC-TEAC vs. AC-DPPH) were significant for all of the six extraction methods and for all cultivars. In conclusion, the extraction method using pectinase enzyme provided the most stable yield of polyphenol content from apple flesh, as confirmed by the examination of four scab-resistant apple cultivars.

“…The poor management of this WAP stream may lead to unfavorable environmental outcomes such as uncontrolled GHG emissions from the disposal of pomace in landfills, unwanted acidification of agricultural soils via leachate formation and also the pollution of underground waters [6]. The utilization of WAP as a biomass resource therefore presents an opportunity for value extraction while also circumventing waste management concerns [7]. The current study therefore seeks to investigate the production of AA from WAP.…”

The global demand for acrylic acid (AA) is increasing due to its wide range of applications. Due to this growing demand, alternative AA production strategies must be explored to avoid the exacerbation of prevailing climate and global warming issues since current AA production strategies involve AA production using fossil resources. Investigations on alternative strategies for AA production therefore constitute an important research interest. The present study therefore assesses waste apple pomace (WAP) as a feedstock for the sustainable AA produc-tion. To undertake this assessment, process models, based on two production pathways were designed, modelled and simulated in ASPEN plus® software. The two competing production pathways investigated include a process incorporating WAP conversion to lactic acid (LA), prior to LA dehydration to generate AA (denoted as the FD pathway) and another process involving WAP conversion to propylene, prior to propylene oxidation to generate AA (denoted as the TFO pathway). Economic and environmental performances of the FD and TFO pathways were assessed via the minimum selling price (MSP) and potential environmental impacts per h (PEI/h) metrics. The study was able to show that the FD pathway presented an improved economic performance (MSP of AA: US $1.17 per kg) performance compared to the economic performance (MSP of AA: US $1.56 per kg) of the TFO pathway. Crucially, the TFO process was shown to present an improved environmental performance (2.07 kPEI/h) compared to the environmental performance of the FD process (8.72 kPEI/h). These observations sug-gests that the selection of the preferred AA production will require a trade-off between the performance measures, and the integration of a multi-criteria decision assessment in future work.

BACKGROUNDKaffir lime peel is a food waste which contains good aromatic essential oil and phenolic compounds. Extraction of essential oil from kaffir lime peel is conducted to obtain the extract for using as biological ingredients in various products. After essential oil extraction, kaffir lime peel residue has been remained, and it can be considered as another by‐product. Therefore, it is interesting to evaluate the contents of phenolic compounds in the kaffir lime peel residue to understand the possibility of valorization of kaffir lime peel wastes at a practical level. In this study, extraction of essential oil from fresh kaffir lime peel was conducted by hydrodistillation, and phenolic compounds were extracted from the kaffir lime peel residue by process optimization of an ethanolic extraction method.RESULTSThrough hydrodistillation and gas chromatography–mass spectrometry analysis, essential oil of kaffir lime peel contained terpinene‐4‐ol (19%), β‐pinene (15.8%) and d‐limonene (15.6%) as the major volatile compounds. In extraction of phenolic compounds from kaffir lime peel residue, all investigated parameters had significant linear effects on the yield of phenolic compounds, but no interaction effects among the extraction parameters were observed. Optimal conditions for the extraction were 120 min, 60 °C and 1:20 g mL−1, resulting in phenolic compounds of 8.6 mg GAE g−1 sample. The phenolic compound yield extracted from fresh kaffir lime peel at the optimal conditions was close to that extracted from the kaffir lime peel residue.CONCLUSIONSThrough hydrodistillation, only essential oil was extracted from kaffir lime peel, while phenolic compounds are still remained in the solid residue of the kaffir lime peel at high concentration as the fresh sample. Results of this study are useful for maximizing extraction yield of phenolic compounds from kaffir lime peel. The results of this study also revealed the possibility of maximizing the utilization of kaffir lime peel wastes at the practical stage through extraction of both essential oils and phenolic compounds. © 2023 Society of Chemical Industry (SCI).
