Determination of Polycyclic Aromatic Hydrocarbons in Olive and Refined Pomace Olive Oils using HPLC/FLD
ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...
متن کاملDetermination of Heterocyclic Aromatic Amines in Heated Meat Samples Using an Efficient Microwave Assisted Extraction and Microextraction Method Followed by HPLC
Background and Objectives: Heterocyclic aromatic amines (HAAs) are carcinogenic and mutagenic substances, which are formed during the heating process of proteinaceous foods such as meat and meat products. The extraction of these compounds from the complex matrix of meat products was carried out by microwave assisted pre-extraction and a precise, rapid and high sensitive microextraction method. ...
متن کاملDetermination of Biologically Active Polyamines in Turkey Breast Meat by HPLC and Derivatization with Dansyl Chloride
BacBackground and Objectives: polyamines (putrecsine, spermidine and spermine) are widespread components, which can be found in most of the foods like meat, fruits, vegetables, cheese and wine. Studies show that reducing the level of polyamines in cells may help to slow down some cancer processes however, dietary polyamines may be required in wound healing, and for growth, maturation and regene...
متن کاملAn Ion-pair Dispersive Liquid-Liquid Microextraction for Simultaneous Determination of Synthetic Dyes in Ice Cream Samples by HPLC
An efficient, sensitive and fast method was developed based on an ultrasound-assisted extraction followed by an ion-pair dispersive liquid-liquid microextraction (USAE-IP-DLLME) for the simultaneous determination of five commonly used synthetic sulfonate dyes (tartarazine, quinoline yellow, sunset yellow, azorubine, and brilliant blue) in ice cream samples using high performance liquid chromato...
متن کاملSimultaneous Determination of Preservatives (Sodium Benzoate and Potassium Sorbate) in Soft Drinks and Herbal Extracts Using High-Performance Liquid Chromatography (HPLC)
Background: Chemical preservation has become an increasingly important practice in modern food technology and herbal medicinal products with the increase in production of processed and convenience products. Objective: In the present study, a reversed-phased HPLC method for simultaneous determination of the preservatives sodium benzoate (SB) and potassium sorbate (PS) is described. Methods: Th...
