Nitric oxide release from a cucurbituril encapsulated NO-donor

Organic & Biomolecular Chemistry

DOI: 10.1039/c8ob00895g

Controlling S-nitrosothiols decomposition, with the consequent release of nitric oxide, is a topic of great research effort. Nitrosomercaptopyridine (SNO+) incorporation into cucurbit[7]uril cavity results in a large increase of its nitrosation equilibrium constant. This effect being a consequence of the stabilization of organic cations by formation of host:guest complexes with CB7 resulting in a drastic reduction of the SNO+ denitrosation rate constant. Moreover SNO+ encapsulation also prevents its decomposition yielding disulfide and nitric oxide. Expulsion of SNO+ from the cucurbirutil cavity by using a competitive guest results nitric oxide release as was confirmed by using a NO selective electrode.

Use of spectroscopic methods in combination with linear discriminant analysis for authentication of food products

Food Control, 2018, 91, 100-112

DOI:10.1016/j.foodcont.2018.03.031

Spectroscopic methods are efficient tools for food authentication due to the advantages of high sensitivity, rapidness, simplicity and their convenience. The combined used of spectroscopic methods and linear discriminant analysis has provided powerful tools for detecting food fraud. This review discusses their operational details, advantages and disadvantages.

Encapsulation of Essential Oils by Cyclodextrins: Characterization and Evaluation

Cyclodextrin: A Versatile Ingredient

doi: 0.5772/intechopen.73589

The essential oils normally had low physicochemical stability and low solubility in water. These facts limit their industrial applications in general and in food formulations particu- larly. This chapter characterizes the physicochemical properties and the antioxidant and antimicrobial activities of three encapsulated essential oils – guava leaf, yarrow and black pepper essential oils – in hydroxypropyl-β-cyclodextrin (HPβCD).
