Honey is a natural sweetener produced by bees (Apis mellifera) from the nectar of flowers of blossoming plants (blossom honey) or from the secretions of plants or the excretions on plants of plant-sucking insects mostly from the family Aphididae (honeydew honey). Characterized by dark colour and by a slightly bitter taste, honeydew honeys show anti...

Orange byproducts are generated from the production of citrus juice and consist of approximately 45–60% of the fruit. It has been estimated that global orange juice production can generate between 0.8 and 1 million tons of byproducts each year. This waste represents for producers not only an underutilized commodity but also a source of environmenta...

The total polyphenol content, antocyanins, proantoacyanidins and some phenols were determined in fifteen red wine samples of the same vintage from single-blended Merlot or Shiraz cultivars. The principal goal of this study was to use these compounds for wine identification and to evaluate the correlation with antioxidant activity. High-performance...

Recently FT-IR spectroscopy has enjoyed renewed interest for detection and quantification of contamination by oils and grease (OG), especially in water samples.

The presence of polycyclic aromatic hydrocarbons (PAHs) in Italian commercial milk samples is reported. The study was carried out on lactating (cow and goat) and plant (rice, soya, oat) milk. The quantitative determination involved liquid-liquid extraction of PAHs, a pre-concentration and determination by HPLC using a fluorescence detector. The rec...

Strawberries represent an important source of bioactive compounds due to their vitamin C and phenolic compound levels, which present high antioxidant effects, beneficial for the maintenance of consumer’s health. Argentina is the second largest strawberry producer in The Common Market of the Southern Cone (MERCOSUR), covering the main export destina...

This paper describes a method for simultaneous identification and quantification of phenolic compounds in strawberries followed by a reversed-phase high performance liquid chromatography (HPLC) with diode array detection. The studied phenolics were flavonoids (flavonols: quercentin, rutin, and kaempferol; flavanols: catechin and epicatechin; anthoc...

The present study reports (i) the covalent immobilization of lipase on different cellulose supports (cotton buds, make-up remover pads, cellulose powder, cotton and tissues) using sodium periodate as activating agent and (ii) its application on the aged linseed oil removal from canvas. The optimization of experimental conditions such as pH, tempera...

This paper describes a quantitative analytical procedure to determine the fatty acid composition in drying oils like linseed, walnut and poppy seed. The procedure required the enzymatic hydrolysis of the oil triacylglycerol families by the action of Candida rugosa lipase. The fatty acids (FFAs) produced (linolenic, myristic, linoleic, palmitic, ole...

Twenty-two pesticides and metabolites, selected on the basis of regional priority lists, were surveyed in thirty Italian mineral waters springs for three years by a procedure based on solid phase extraction in combination with gas chromatography coupled with mass spectrometry detection. The procedure proved to be simple, sensitive and reliable, the...

Polychlorinated biphenyls are toxic pollutants characterized by persistence in the atmosphere and ability to accumulate in food chains. Like other persistent organic pollutants, polychlorinated biphenyls are still present in the environment despite their almost worldwide prohibition. In this study we propose a simple and a rapid liquid-liquid micro...

Over the years, pathological implications have often been remarked in the free radicals formation in the human body, underlining how a diet rich in antioxi-dant substances can be able to limit oxidative damage. Free radicals are extreme-ly harmful to living organisms to do they attack different constituents cell, which leads to acceleration of the...

A chromatographic method to determine pesticide residues in cereals by high-performance liquid chromatography (HPLC) and ultraviolet (UV) detection has been described.
