“…Briefly, maintaining constant concentrations of 0.1% (w/v) CP (GENU® Pectin, DE = 36%, CP‐Kelco, USA) and 0.05% (w/v) low acyl GG (Kelcogel, CP‐Kelco, USA), combinations of AS (50 and 75 AU/ml) and EDTA (1, 4, and 8 mM) were tested for the antibacterial activity against E. coli , S. aureus, and L. monocytogenes in BHI, with initial concentrations of 1 × 10 5 CFU per well. The AS and EDTA concentrations were proposed based on previous reports (Jiménez‐Villeda et al., 2019; Trejo‐González et al., 2018). The plates were incubated at 35°C, reading the absorbance (545–630 nm) at 0, 20, 22, and 24 hr in a Stat Fax 2,100 equipment, Awerness Technology Inc. Three independent experiments were performed.…”

A fish‐packaging film was prepared with 0.4% gellan gum (GG), 2% citrus pectin (CP), 0.75% glycerol, EDTA 1 mM, and 50 arbitrary‐units (AU)/ml of antimicrobial‐activity supernatants (AS) from Streptococcus infantarius cultures containing bacteriocin‐like compounds of 5–10 kDa. The formulation was based on a minimum inhibitory condition (AS, 50 AU/ml; EDTA, 1 mM; CP, 0.1%; GG, 0.05%) for 105 CFU/well of Escherichia coli, Staphylococcus aureus or Listeria monocytogenes growing in BHI at 35°C, 24 hr. The films entirely inhibited the growth of the three bacteria in two model fish media, containing trout or tilapia, at two incubation‐conditions: 9°C, 90% RH, 30‐day; and 35°C, 35% RH, 7‐day. Furthermore, wrapped fresh‐fillets of trout or tilapia exhibited the lowest total‐aerobes counts, 8 × 106–1 × 107 CFU/g, after 7‐day‐incubation at accelerated conditions (25 ± 2°C, 60 ± 10% RH), showing the film‐potential. The film‐physical‐mechanical properties (Young’s modulus; elongation and stress at break; oxygen and water vapor permeability) were slightly affected by the EDTA‐AS contents. Practical applications Development of a biodegradable‐film based on citrus pectin, and gellan gum, enriched with EDTA and antimicrobial substances produced by Streptococcus infantarius, for hindering the growth of pathogen bacteria (i.e., Escherichia coli, Staphylococcus aureus, and Listeria monocytogenes) and total aerobes that would contaminate and/or deteriorate fresh fish, like trout and tilapia.

“…Catimor) is a promising source of low methoxyl pectin. Unlike the antimicrobial properties of pectin from the previous study, which used pectin as a carrier for antimicrobial agents such as silver nanoparticles or essential oils [8,9,18,19], this type of pectin can be used in the biomedical or pharmaceutical fields without structure modification. The boiling extraction method seems to be the most appropriate for largescale extraction, as it yielded the highest amount of pectin.…”

“…In the previous study, the antimicrobial activity of pectin alone was not extensively reported in the literature. However, a report that used citrus pectin in the functional films showed inhibitory effects against L. monocytogenes, E. coli and S. aureus [8,9]. Furthermore, Daoud et al [10] reported that the lyophilized citrus pectin showed activities against 16 clinical isolates and 2 reference strains of Helicobacter pylori.…”

This study aimed to utilize the waste from the coffee bean production process as high value-added material. Pectin extracted from the coffee pulp was classified as low methoxyl pectin (LMP) with the Degree of Esterification (DE) at 33.33 % For further application or upscaling production, the coffee pulp was boiled to retrieve the highest yield at 15.68 g/100 g DW. The antimicrobial assays of crude pectin via minimum inhibition concentration (MIC) showed that coffee pectin could inhibit the growth of Staphylococcus aureus TISTR 1466 in the range of 2.5 - 0.62 mg, while the commercial apple pectin exhibited the inhibition only slightly. The pectin film from the coffee pectin blended with the commercial apple pectin also exhibited antimicrobial activity against S. aureus TISTR 1466. This study shows that coffee pectin could be an alternative material for antibacterial film and other applications. HIGHLIGHTS Pectin extracted from the coffee pulp by this extraction method is classified as low methoxyl pectin with the degree of esterification (DE) at 33.33 % which retrieve the highest yield at 15.68 g/100 g DW of coffee pulp The minimum inhibition concentration (MIC) of the coffee pectin against Staphylococcus aureus TISTR 1466 in the range of 2.5 - 0.62 mg, while the commercial apple pectin did not exhibit antimicrobial activity The pectin film from the coffee pectin 5 % blended with the commercial apple pectin also exhibited antimicrobial activity against aureus TISTR 1466 Given its antibacterial activities, as well as the ability to form film, coffee pectin could be potentially used for application in biomedical or pharmaceutical fields. Importantly, pectin from the coffee pulp could add more value to coffee by-products GRAPHICAL ABSTRACT

Antimicrobial resistance is the leading cause of burden on healthcare sector. There is scientific challenge of developing new functional material as a platform to prevent and treat viral and microbial infection and cosmetic utility. In material chemistry, there is progress in the development of functional material with advent of nanotechnology with aid of synthetic organic chemistry. The properties and application of material can be changed significantly by modification of the surface functional groups (namely, COOH, HO, NH2OH, SO4,), formation of composite with inorganic material and incorporation of active pharmaceutical agents. In antibacterial application functional material of copper, silver, gold, platinum, tin, iron, cobalt, ruthenium, zinc and pharmaceutical antimicrobial agents found utility in the treatment of bacterial and hospital acquired infection with different resistant strains of microorganisms. In antiviral application many functional materials have been shown to possess remarkable antiviral ability like quantum dots, gold and silver nanoparticles, nanoclusters, carbon dots, graphene oxide and silicon materials. The polymers and dendrimers functionalized with USFDA approved antiviral agent also has potential therapeutic outcomes. Despite their difference in antiviral mechanism and inhibition efficacy, these functional material structures have unique features as potential antiviral candidates. In cosmetic applications functional material based on mica, sericite, fullerene, charcoal, peptides, mineral, lipids, glucocorticoid, nanocellulose hybrid material are extensively used. In this review, we have highlighted early promise and prospects of functional material for cosmetics, antibacterial and antiviral applications, advantages and disadvantages, Patent scenario, current challenges for translation into commercial products.
