“…they suggest that GSE and the hydrophobicity of essential oils may be responsible for the high TPC. Extracts of other natural substances have similar effects, Kowalczyk et al(2021) found that the addition of berglass extract to CS/кC lms revealed an increase in total phenolic content, FE can also delay starch regeneration. Meanwhile, smart lms were prepared using pectin and polyphenol-rich extracts by Ribeiro et al (2021), they found that mainly the total phenolic substances played a key role.…”

A biodegradable packaging film with antioxidant and antibacterial activity was developed by adding grape seed ethanol extract (1%、3%、5% per g of starch) to corn starch/κ-carrageenan (CS/кC) complex film made using the solvent casting method. The κ-carrageenan is a promising film-forming polymer with highly elastic and adhesive properties. The addition of GSE enhanced the water vapor permeability, break elongation, and opacity of the film, and this is related to the excellent dispersion of GSE in CS/кC film observed by scanning electron microscope, and the formation of intermolecular hydrogen bond between GSE and CS proved by FT-IR. Thermogravimetric analysis showed that the CS/кC -5% GSE film has a high glass transition temperature (121.65℃). With the increase of GSE content, it improved the antioxidant capacity (DPPH radical scavenging 26.5% and ABTS radical scavenging 45.0%) and antibacterial activity (Bacteriostatic circle diameter of E. coli 12.78 ± 0.42 mm and S. aureus strains 13.52 ± 0.66 mm) of CS/кC films. Simulated food packaging experiments presented that CS/кC-GSE film significantly reduced the peroxide value of lard (P < 0.05). The above results indicate that the GSE can be used as a food-grade packaging material and has a good application prospect in the food industry.

“…The lms were prepared from aqueous solutions of the proteins (5% w/w), glycerol (2% w/w), and FE (0, 0.0125, 0.025, 0.05% w/w) according to the previous procedure (Kowalczyk et al, 2021c). Brie y, the protein/glycerol solutions were heated (90°C, 30 min), cooled (~40 °C), mixed with FE, homogenized (30 000 rpm, 2 min), degassed, cast on trays, and dried (~25ºC, 50% relative humidity (RH), 24 h).…”

“…A recent study has shown that a freeze-dried aqueous reweed extract (FE) exhibits a set of numerous antioxidant activities (Szwajgier et al, 2021). Based on this nding, the FE has been used for producing active lms based on methyl cellulose (MC) and corn starch (CS) (Kowalczyk et al, 2021a;Kowalczyk et al, 2021c). Polyphenols can interact with proteins through numerous interactions, leading to the formation of soluble or insoluble complexes.…”

The properties of gelatin (GEL) and whey protein isolate (WPI) edible films incorporated with fireweed extract (FE, 0-0.05%) were compared. The GEL films had more crystalline structure, thus were mechanically stronger and less permeable to water vapor than the WPI films. Furthermore, GEL offered more transparent, less yellow, and more stretchable films. In turn, the WPI films had superior UV-protective potential. An increase in the FE concentration yielded films with improved UV-blocking ability. The WPI films incorporated with higher levels of FE (0.025–0.05%) exhibited better antiradical potential in comparison to the GEL films. This result indirectly indicates that the WPI-based films, being more soluble and less swellable, ensured faster release of FE than the GEL films. The slower building up of the antiradical activity of the FE-supplemented GEL films suggests that GEL could be more useful in the development of slow/less migratory active packaging systems for high moisture food.

The present study was designed to appraise the photoprotective, antioxidant, and antibacterial bioactivities of Ruellia tuberosa leaves extracts (RtPE, RtChl, RtEA, RtAc, RtMe, and RtHMe). The results showed that the RtHMe extract of leaves of R. tuberosa was rich in total phenolic content i.e., 1.60 mgGAE/g dry extract, while TFC highest total flavonoid content was found in RtAc extract, i.e., 0.40 mgQE/g. RtMe showed effective antioxidant activity (%RSA: 58.16) at the concentration of 120 µL. RtMe, RtEA and RtHMe exhibited effective in vitro antibacterial activity against Gram‐negative bacteria (E. coli). In silico docking studies revealed that paucifloside (‐11.743 kcal/mol), indole‐3‐carboxaldehyde (‐7.519 kcal/mol), nuomioside (‐7.275 kcal/mol), isocassifolioside (‐6.992 kcal/mol) showed best docking score against PDB ID 2EX8 [penicillin binding protein 4 (dacB) from Escherichia coli, complexed with penicillin‐G], PDB ID 6CQA (E. coli dihydrofolate reductase protein complexed with inhibitor AMPQD), PDB ID 2Y2I [Penicillin‐binding protein 1B in complex with an alkyl boronate (ZA3)] and PDB ID 2OLV (from S. aureus), respectively. Docked phytochemicals also showed good drug likeness properties.
