“…To carry out the target compounds, increase the solvating capacity of solvents by increasing their diffusivity (Abdul Aziz et al, 2020). Contradictory data show that high temperatures will influence bioactive compounds while also causing the degradation of thermo‐labile bioactive compounds (Rasidek et al, 2021). An increase of flowrate of 2.5–7.5 ml/min at constant pressure 4 and 6 MPa decreases the catechin recovery.…”

A study on the valorization of peanut (Arachis hypogea) skin as agricultural waste to recover bioactive compounds, including catechin and epicatechin, by subcritical ethanol extraction (SEE) is unexplored scientifically. Thus, this study aims to determine the parameter effects on peanut skin extract recovery by SEE, followed by identifying the semi-empirical modeling. The best conditions were 6 MPa, 4.53 ml/min, 86.23 C with responses of catechin 188.66 μg/g and epicatechin 336.41 μg/g. High pressure and temperature conditions are conducive to catechin recovery, whereas high pressure with low-temperature conditions is suitable for epicatechin enhancement. Del Valle Aguilera (DVA) fits the solubility of catechin and epicatechin in SEE effectively compared with the Chrastil model since it has the lowest average absolute relative deviation (AARD), which is 5.97% and 12.69%, respectively. As a result, this approach (SEE) may be used in place of the conventional method for extracting catechin and epicatechin for medicinal purposes.

“…Figure 2 also shows that at a flow rate of 12.5 ml/min and pressure of 10 and 15 MPa, there was a noticeable rise in temperature and a drop in TCC recovery. The bioactive compounds will be affected by high temperatures, and as a result, the compounds will be damaged (Rasidek et al, 2021). The raising pressure at a flow rate of 12.5 ml/min while maintaining a temperature of 120 and 160°C improves TCC recovery.…”

Subcritical water extraction (SWE) is a process for extracting valuable compounds of catechin and epicatechin from the skin of the peanut (Arachis hypogea). The research's objective was to identify the best extraction conditions for recovering total catechin compounds (TCC), total epicatechin compounds (TEC), and total yield from peanut skin. The solubility of yield in subcritical water was determined using the Chrastil and Del Valle Aguilera models. The best conditions were 13.56 MPa, 11.66 ml/min, 160°C with responses of TCC 10.81 mg/g, TEC 8.41 mg/g, and yield 0.268 g/g. High pressure and temperature conditions were conducive to TEC recovery, whereas high flow rate conditions were suitable to TEC and total yield enhancement. The Chrastil model fits the solubility of yield in subcritical water effectively since it has the lower average absolute relative deviation, which is 85.507% compared to Del Valle Aguilera of 85.509%. The Chrastil and Del Valle Aguilera model was not suitable for the solubility of peanut skin extract due to high percentage of AARD. Practical applications The catechin and epicatechin from peanut skin were frequently recovered using a hazardous solvent in a traditional extraction procedure. Subcritical water extraction is one of the methods for overcoming the toxicity of solvents. The best condition for obtaining maximum total catechin compounds (TCC), total epicatechin compounds (TEC) was determined using response surface methodology. Furthermore, in this work, a semi‐empirical model was utilized to evaluate the effect of parameters to improve the solubility of bioactive compounds. TEC recovery was enhanced by high pressure and temperature, while TEC and total yield augmentation were enhanced by high flow rate.

“…Otherwise, in our previous study using the batch system of SWE was in ranging from 0.72 to 4.88 %. At higher temperatures in the batch system, SWE would activate to break down the pectin molecules as pectin is composed of α-(1-4) linked units of galacturonic acid (GA) or methyl ester (-CH3), that happened at 160°C [13]. Contrarily, Swamy and Muthukumarappan [14] reported a lower banana peel pectin yield that was only achieved at 2.58 %, as they use the intermittent microwave extraction method.…”

The dumping of waste banana peels from local chip manufacturing has encouraged sustainable food trends to valorize these peels as pectin sources. In this study, soluble pectin from banana peels was extracted using a continuous subcritical water extraction system (SWE). This method was a promising fast extraction process with a water solvent that was environmentally friendly. Temperature (100 to 160 °C) and extraction time (5 to 50 minutes) were manipulated, with a fixed pressure of 15 MPa, a flow rate of 15 mL/min, and a particle size of 0.6 mm. The response surface methodology (RSM) was used to generate approximately 13 experimental trials from the central composite design. Based on linear and square models, the results revealed that the interaction of temperature and time to pectin yield had a significant effect. At 100°C for 5 minutes, an optimal condition for producing pectin yield was achieved, which risen the highest pectin yield by 26%. As a result, the SWE continuous system promoted increased pectin production in the shortest extraction time. In short, banana peel pectin is a powder that serves a primary function in numerous food, pharmaceutical, and cosmeceutical applications.
