“…The percentage of normal probability plot of residuals was typically scattered near along the straight line, which denotes a tolerable devia-tion of variance. A good agreement between the model and the experimental data observed can be qualitatively justified by using a Predicted vs. Actual plot (parity plot) [19]. The accuracy of the model can be understood by evaluating the normal distribution with the predicted and actual results, as exhibited in Figure 1 (Figure 1b), the actual values of hemicellulose and cellulose are moderately close to the predicted line, which was obtained from the developed model in previous Eq.…”

In this study, the optimization of microwave-assisted alkaline (MAA) pretreatment is performed to attain the optimal operating parameters for the delignification of cocoa pod husk (CPH). The MAA performance was examined by heating the CPH solid with different particle sizes (60–120 mesh) and NaOH solution with a different sample to a solvent (SS) ratio (0.02–0.05 g/L), for short irradiation time (1–4 min). Box-Behnken Design (BBD) was utilized to optimize the percentage of lignocellulose composition changes. The results show that by enlarging particle size, the content of lignin and cellulose decreased while hemicellulose increased. By prolong irradiation time, the content of lignin and hemicellulose decreased while cellulose elevated. On the other hand, increasing the SS ratio was not significant for hemicellulose content changes. From FTIR and SEM characterization, the MAA drove the removal of lignin and hemicellulose of CPH and increased cellulose slightly. Supported by kinetic study which conducted in this work, it was exhibited that MAA pretreatment technology is an effective delignification method of CPH which can tackle the bottleneck of its commercial biofuel production.

“…The positive effect of temperature can be explained by the increase in solubility of the phenolic compounds with an increase in temperature (Fachri et al, 2020). It is also seen from the figure that the solvent type affects the extraction efficiency of the phenolic compounds.…”

This study aimed to determine optimum conditions of the ultrasound assited extraction (UAS) parameters for different solvent types by using response surface methodology (RSM) and Box-Behnken design. The model parameters namely, time, temperature and ultrasound power significantly affected TPC value of the propolis extract (P < 0.05). The optimum process parameters were determined as 2.95 min, 58.61 °C and 615.26 W for ethanol, 3 min, 60°C and 580 W for dimethyl sulfoxide (DMSO), 3 min, 59 °C and 591 W for Propylene glycol (PG) and 2.70 min, 59.19 °C and 591.73 W for distilled water (DW). The extracts obtained from optimum conditions were compared with conventional solvent extraction methods (CSE). The chrysin was determined as a major phenolic compound and its value significantly differed based on the extraction and solvent types (P < 0.05). This study suggested that the ethanolic extracts obtained from UAS could be used as natural antimicrobial and antioxidant source.

“…The low operation temperature of supercritical CO 2 extraction is beneficial to preserve the chemical structure and bioactivity of polyphenolic compounds in the extract. It has been demonstrated that pressure, temperature, CO 2 mass flow rate, time, and the type and percentage of cosolvents are important factors affecting the extraction yield and composition of polyphenolic compounds (De Zordi et al., 2014; Fachri, Sari, Yuwanti, & Subroto, 2020). Therefore, the operation conditions of supercritical CO 2 extraction should be optimized to maximize the yield of polyphenolic compounds, whereas to minimize the coextraction of undesirable substances.…”

The development of active packaging films and edible coatings based on biopolymers and natural bioactive substances has received increasing attention in recent years. Propolis, also called bee glue, is a natural resin substance collected by worker‐bees from the mucilage, gum, and resin of several plants. In food industry, propolis is commonly extracted in solvents to afford polyphenol‐rich extract with potent antimicrobial and antioxidant activities. The prepared propolis extract can be mixed with biopolymers, plasticizers, emulsifiers, and reinforcing agents to develop active packaging films and edible coatings. The functionality of active packaging films and edible coatings is closely related to the type, harvesting method, geographic origin, extraction method and extraction conditions of propolis, the content and composition of polyphenolic compounds in the extract, and the presence of other bioactive substances. Active packaging films and edible coatings based on propolis extract can impact the physical, biochemical, and sensory properties of food (e.g., fruits, vegetables, meat, and fish) during storage. This review focuses on the recent advances of active packaging films and edible coatings based on polyphenol‐rich propolis extract. The impact of polyphenol‐rich propolis extract on the structural characterization, functionality, and potential food applications of the films and edible coatings is summarized.
