“…A peptide made up of 34 amino acids is classified as Generally Recognized Safe (GRAS) by the FDA and its use as a food preservative (E234) has been allowed by the European Union since 1983, however, it does not act against Gram-negative bacteria, yeasts, or fungi. This substance, in combination with chelating agents (organic acids, EDTA) or emulsifying agents (Tween 80), shows a great inhibitory activity against Gram-negative bacteria since the protective cell membrane is altered allowing the formation of pores and, as a result of that, the ion output and loss of the proton matrix force are caused, thus generating cell death [ 28 , 29 ]. In combination with nisin, for example, prior studies have shown this nisin-EDTA combination to be effective against other gram-negative bacteria such as Salmonella typhimurium [ 30 ].…”

In this study, we developed gelatin-based films for active packaging with the ability to inhibit E. coli. We created these novel biodegradable gelatin-based films with a nisin-EDTA mix. FT-IR, TGA, and SEM analysis showed that nisin interacted with the gelatin by modifying its thermal stability and morphology. The use of nisin (2,500 IU/mL) with concentrations of Na-EDTA (1.052 M stock solution) distributed in the polymer matrix generated a significant decrease in the growth of E. coli when compared to the control. In freshly made films (t0), the growth of E. coli ATCC 25922 was reduced by approximately 3 logarithmic cycles. Two weeks after the films were made, a reduction in antimicrobial activity was observed in approximately 1, 1 and 3 logarithmic cycles of the films with 5%, 10% and 20% of the compound (nisin/Na-EDTA) distributed in the polymer matrix, respectively. This evidences an antimicrobial effect over time. Also, biodegradation tests showed that the films were completely degraded after 10 days. With all these results, an active and biodegradable packaging was successfully obtained to be potentially applied in perishable foods. These biodegradable, gelatin-based films are a versatile active packaging option. Further research on the barrier properties of these films is needed.

“…Spoilage microbes produced hydrolytic enzymes such as proteases, cellulases, pectinases, and xylanases, which induced enzymatic degradation in potatoes (Ajingi et al, 2020). In the United States and other countries, incidents of outbreaks of gastroenteritis have been reported because of consuming fresh-cut potato salads contaminated with Salmonella (Mank et al, 2010;Voss et al, 2012).…”

Potato is ranked as the world's fourth most popular staple food with about 5,000 varieties worldwide (Zaheer & Akhtar, 2016).In terms of production, potato is the third most produced crop (405.83 million tons) after rice (862 million tons) and wheat (809.14 million tons) (FAOSTAT, 2019). Food and Agriculture Organization (FAO) regarded potatoes as a solution for world hunger and poverty during the international year of the potato (FAO, 2008). Carbohydrate-rich potatoes are packed with

“…In the past years, the development of technologies for reducing CO 2 emissions has been in the forefront of research. From an economical point of view, a promising way of decreasing CO 2 emissions is the capture of CO 2 at the source of production (e.g., at industrial sites) and the conversion to value-added products, for example, formic acid, methanol, propylene, and urea. − In the chemical industry, formic acid (FA, HCOOH) is a primary product with a production capacity of 800,000 tons per year as of 2017. , A wide range of products are synthesized from FA. − It is, for example, used for the hydrothermal decarbonylation and decarboxylation in the water–gas-shift reaction, as a preservative (antibacterial cocktail in the prevention of potato spoilage), as an antibacterial in livestock feed (control of luminous vibriosis disease in shrimp aquaculture), and as a hydrogen storage material …”

Solubility of CO₂ in Aqueous Formic Acid Solutions and the Effect of NaCl Addition: A Molecular Simulation Study

et al. 2022

There is a growing interest in the development of routes to produce formic acid from CO2, such as the electrochemical reduction of CO2 to formic acid. The solubility of CO2 in the electrolyte influences the production rate of formic acid. Here, the dependence of the CO2 solubility in aqueous HCOOH solutions with electrolytes on the composition and the NaCl concentration was studied by Continuous Fractional Component Monte Carlo simulations at 298.15 K and 1 bar. The chemical potentials of CO2, H2O, and HCOOH were obtained directly from single simulations, enabling the calculation of Henry coefficients and subsequently considering salting in or salting out effects. As the force fields for HCOOH and H2O may not be compatible due to the presence of strong hydrogen bonds, the Gibbs–Duhem integration test was used to test this compatibility. The combination of the OPLS/AA force field with a new set of parameters, in combination with the SPC/E force field for water, was selected. It was found that the solubility of CO2 decreases with increasing NaCl concentration in the solution and increases with the increase of HCOOH concentration. This continues up to a certain concentration of HCOOH in the solution, after which the CO2 solubility is high and the NaCl concentration has no significant effect.
