Critical Reviews in Food Science and Nutrition | Year: 2011
Due to increased demands for greater stringency in relation to hygiene and safety issues associated with fresh food products, coupled with ever-increasing demands by retailers for cost-effective extensions to product shelf-lives and the requirement to meet consumer expectations in relation to convenience and quality, the food packaging industry has rapidly developed to meet and satisfy expectations. One of the areas of research that has shown promise, and had success, is modified atmosphere packaging (MAP). The success of MAP-fresh meat depends on many factors including good initial product quality, good hygiene from the source plants, correct packaging material selection, the appropriate gas mix for the product, reliable packaging equipment, and maintenance of controlled temperatures and humidity levels. Advances in plastic materials and equipment have propelled advances in MAP, but other technological and logistical considerations are needed for successful MAP systems for raw chilled meat. Although several parameters critical for the quality of MA packed meat have been studied and each found to be crucial, understanding of the interactions between the parameters is needed. This review was undertaken to present the most comprehensive and current overview of the widely available, scattered information about the various integrated critical factors responsible for the quality and shelf life of MA packed meat with an interest to stimulate further research to optimize different quality parameters. © Taylor and Francis Group, LLC.

A novel composite ion exchange adsorbent has been synthesized and characterized by using sophisticated techniques. The physicochemical parameters were also established to determine preliminary ion uptake properties of the exchanger. The material synthesized at pH 0.7, demonstrates promising ion exchange capacity (1.56 meq g-1 for Ba2+) together with chemical and thermal stability. It retains 76.4% ion exchange capacity up to 500 °C and shows higher uptake capacity than stannic selenite, stannic tungestoaresenate, and stannic molybdoaresenate. X-ray and SEM analyses show the amorphous nature of the material. On the basis of chemical composition and FTIR analysis a tentative formula has been assigned as (SnO2)(HMoO 4)2(CH2CHCONH2) nH2O. The distribution coefficients behavior of material toward diverse metal ions was studied by varying the concentration of acid solvents. The practical usefulness of the material has been demonstrated by separating Cd2+ ions quantitatively from a synthetic mixture. © 2012 American Chemical Society.

A series of new substituted 3-formyl chromone derivatives (4-6) were synthesized by one step reaction methodology by knoevenagel condensation, structurally similar to known bisintercalators. The new compounds were characterized by IR, 1H NMR, 13C NMR, MS and analytical data. The in vitro DNA binding profile of compounds (4-6) was carried out by absorption, fluorescence and viscosity measurements. It was found that synthesized compounds, especially compound 6 (evident from binding constant value) bind strongly with calf thymus DNA, presumably via an intercalation mode. Additionally, molecular docking studies of compounds (4-6) were carried out with B-DNA (PDBID: 1BNA) which revealed that partial intercalative mode of mechanism is operational in synthesized compounds (4-6) with CT-DNA. The binding constants evaluated from fluorescence spectroscopy of compounds with CT-DNA follows the order compound 6 > compound 5 > compound 4. All the compounds (4-6) were screened for acetylcholinesterase inhibition assay. It can be inferred from data, that compound (6) showed potent AChE inhibition having IC50 = 0.27 μM, almost in vicinity to reference drug Tacrine (IC50 = 0.19 μM). © 2013 Elsevier B.V.

An overview of surfactant–amino acid interactions mainly in aqueous medium has been discussed. Main emphasis has been on the solution thermodynamics and solute–solvent interactions. Almost all available data on the topic has been presented in a lucid and simple way. Conventional surfactants have been discussed as amphiphiles forming micelles and amino acids as additives and their effect on the various physicochemical properties of these conventional surfactants. Surfactant–surfactant interactions in aqueous medium, various mixed surfactant models, are also highlighted to assess their interactions in aqueous medium. Finally, their applied part has been taken into consideration to interpret their possible uses. © 2015, Springer Science+Business Media New York.

The formation of the polyion-complex between three cationic diester-bonded Gemini surfactants and DNA has been demonstrated systematically. This was studied through the electrostatic attraction between ammonium head groups of Gemini surfactants and the phosphate groups of DNA. Ethidium bromide exclusion assay indicates the interaction between DNA and diester-bonded Gemini surfactants. DNA binding abilities with the Gemini surfactant depends on tail length which has been demonstrated by agarose gel electrophoresis and circular dichroism (CD) measurements. Dynamic light scattering measurements reveal that the ester-bonded Gemini surfactants can induce the collapse of DNA into densely packed bead-like structures with smaller size. Molecular docking technique was also utilized to understand the mode and mechanism of interaction between DNA and the Gemini surfactants (pre-micellar form). In addition to electrostatic interactions between the negatively charged phosphate backbone of DNA and positively charged head groups of Gemini surfactants, self-association due to hydrophobic interactions between the alkyl tails of surfactant and the hydrogen bonding between the ester group of surfactant and nucleotide bases, result in the compaction of nucleotides. © 2014 Elsevier B.V.
