“…When the pressure raises, the density of the supercritical fluid increases, which may favour both the swelling of the matrix and the solubility of the compounds. This behaviour agrees with the literature on the impregnation of polyester and cotton natural fibers with natural extracts, as well as on the impregnation of PET/PP films with natural extracts [ 42 , 45 , 64 ]. Based on these results, a pressure of 50 MPa was selected for the experiments to be carried out later on.…”

There is an increasing demand for the use of new food packaging materials. In this study, natural jute fibers impregnated with a Petit Verdot Red Grape Pomace Extract (RGPE) was proposed as a new active food packaging material. Pressurized Liquid Extraction (PLE) and Enhanced Solvent Extraction (ESE) techniques were employed to obtain the bioactive RGPE. Afterward the supercritical solvent impregnation conditions to obtain RGPE-natural jute fibers were studied, by varying pressure, modifier percentage and dried RGPE mass. PLE technique offered the highest bioactive extract at 20 MPa, 55 °C, 1 h residence time using C2H5OH:H2O (1:1 v/v), providing an EC50 of 3.35 ± 0.25 and antibacterial capacity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa (MIC of 12.0, 1.5 and 4.0 mg/mL RGPE respectively). The natural jute fibers impregnated with 3 mL of that RGPE (90 mg/mL) at 50 MPa and 55 °C generated the most efficient packing material with regards to its food preservation potential.

“…The extractions were carried out in a high-pressure equipment (Thar Technologies SF100, Pittsburgh, PA, USA) described in a previous work [ 42 ] ( Figure 1 ). 20 g of RGP was loaded into a paper filter cartridge and it was installed inside the extraction vessel.…”

“…Later on, Celimene et al (1999) impregnated maple with a mixture of pinosylvins, and Seppanen et al (2004) birch and aspen, to reduce fungal decay. Recently, the textile industry has become interested in polyphenol impregnation to inhibit the bacterial growth ( Sanchez-Sanchez et al 2017 ). Furthermore, novel food packaging (e.g., Busolo and Lagaron (2015) ) and medical (e.g., resveratrol in diabetic wound area ( Gokce et al 2017 )) applications have been developed.…”

Antifungal stilbene impregnation: transport and distribution on the micron-level

et al. 2018

The transition from the living water-transporting sapwood to heartwood involves in many tree species impregnation with extractives. These differ in amount and composition, and enhance resistance against bacteria, insects or fungi. To understand the synthesis, transport and impregnation processes new insights into the biochemical processes are needed by in-situ methods. Here we show the extractive distribution in pine (Pinus sylvestris) microsections with a high lateral resolution sampled in a non-destructive manner using Confocal Raman Microscopy. Integrating marker bands of stilbenes and lipids enables to clearly track the rapid change from sapwood to heartwood within one tree ring. The higher impregnation of the cell corner, compound middle lamella, the S3 layer and pits reveals the optimization of decay resistance on the micron-level. Furthermore, deposits with changing chemical composition are elucidated in the rays and lumen of the tracheids. The spectral signature of these deposits shows the co-location of lipids and pinosylvins with changing ratios from the living to the dead tissue. The results demonstrate that the extractive impregnation on the micro- and nano-level is optimized by a symbiotic relationship of lipids and pinosylvins to enhance the tree’s resistance and lifetime.

“…As previously mentioned, plant extracts have been recognized as an important source of antibacterial agents. Sanchez-Sanchez et al [27] reported results on the SSI of polyester textiles with mango leaf extract previously obtained by supercritical fluid extraction (SFE) with CO 2 in the presence of methanol as a cosolvent. The impregnation process was conducted in a batch mode in the presence of methanol as well.…”

Bacterial resistance to antibiotics is one of the biggest problems in the modern world. The prevention of bacterial spreading from hospitals to the community and vice versa is an issue we have to deal with. This review presents a vast potential of contemporary high-pressure techniques in the design of materials with antimicrobial activity. Scientists from all over the world came up with ideas on how to exploit extraordinary properties of supercritical fluids in the production of advantageous materials in an environmentally friendly way. The review summarizes reported methods and results.
