Applications of Fruit Polyphenols and Their Functionalized Nanoparticles Against Foodborne Bacteria: A Mini Review

The ingestion of contaminated water and food is known to cause food illness. Moreover, on assessing the patients suffering from foodborne disease has revealed the role of microbes in such diseases. Concerning which different methods have been developed for protecting food from microbes, the treatment of food with chemicals has been reported to exhibit an unwanted organoleptic effect while also affecting the nutritional value of food. Owing to these challenges, the demand for natural food preservatives has substantially increased. Therefore, the interest of researchers and food industries has shifted towards fruit polyphenols as potent inhibitors of foodborne bacteria. Recently, numerous fruit polyphenols have been acclaimed for their ability to avert toxin production and biofilm formation. Furthermore, various studies have recommended using fruit polyphenols solely or in combination with chemical disinfectants and food preservatives. Currently, different nanoparticles have been synthesized using fruit polyphenols to curb the growth of pathogenic microbes. Hence, this review intends to summarize the current knowledge about fruit polyphenols as antibacterial agents against foodborne pathogens. Additionally, the application of different fruit extracts in synthesizing functionalized nanoparticles has also been discussed.     

Thermochemical reactivity of manganese(IV) oxides in reducing atmosphere

The thermochemical reduction of a series of structurally and morphologically different natural and synthetic manganese(IV) oxides has been investigated. Measurements have been performed by means of combined thermogravimetry/mass spectrometry, X-ray diffraction and analytical scanning electron microscopy. The mechanisms of the degradation of these materials have been characterized in order to establish standardized procedures for their reactivity as function of structure, morphology and experimental conditions. The corresponding results are the fundament with respect to a reproducible technical application.The authors would like to thank Dr. R. Lenck for compositional analyses of the investigated compounds. The financial support of the Chemetall GmbH, Frankfurt, Germany as well as the Fond der Chemischen Industrie is also acknowledged.     

Recent Developments in Therapeutic and Nutraceutical Applications of p-Methoxycinnamic Acid from Plant Origin

The p-methoxycinnamic acid (p-MCA) is one of the most studied phenylpropanoids with high importance not only in the wide spectrum of therapeutic activities but also its potential application for the food industry. This natural compound derived from plants exhibits a wide range of biologically useful properties; therefore, during the last two decades it has been extensively tested for therapeutic and nutraceutical applications. This article presents the natural sources of p-MCA, its metabolism, pharmacokinetic properties, and safety of its application. The possibilities of using this dietary bioactive compound as a nutraceutical agent that may be used as functional food ingredient playing a vital role in the prevention and treatment of many chronic diseases is also discussed. We present the antidiabetic, anticancer, antimicrobial, hepato-, and neuroprotective activities of p-MCA and methods of its lipophilization that have been developed so far to increase its industrial application and bioavailability in the biological systems.     

Enthalpies of mixing of aqueous solutions of the amino acids glycine,l-alanine and l-serine

The enthalpies of mixing of aqueous solutions of the three amino acids glycine, L-alanine and L-serine have been determined at 25°C. These data have been analyzed, using the McMillan-Mayer theory, to obtain the various enthalpic pair interaction coefficients, h_xy. The results are discussed in terms of the likely molecular interactions. The application of the Savage-Wood additivity principle to these solute systems is also considered.     

Substoichiometric extraction of metals and its application to the determination of heavy metals in environmental samples by neutron activation analysis

The decontamination factor, accuracy, precision, sensitivity and radiochemical purity of the separated fraction have been discussed.     

Zuordnung offenkettiger Diastereomerer mittels lanthanoiden-induzierter Verschiebungen (LIS)

The LIS method has been tested for assignment purposes of acyclic diastereomers. After the estimation of the coordination geometry Eu ... O for some alkyl-methyl-ethers, the ground state conformations of the coordinated substrates have been determined and related to the free substrates. Due to obtained differences, the application of the LIS method for present assignment purposes should be limited to strained, less flexible stereoisomers.
