AN361: Extraction of Total Fat from Food Samples After Acid Hydrolysis Using Accelerated Solvent Extraction with GC-MS Analysis

Instrument Type: Automated Sample Prep

Complex matrices such as food typically require acid hydrolysis or pretreatment prior to solvent extraction. Our newly updated flow-through solvent extraction system allows extraction of matrices which require acidic or alkaline pretreatment. The ability to extract these pretreated matrices significantly expands the capabilities of accelerated solvent extraction technology.This Application Note describes methods used for extraction of total fat from food samples and determination of fat content by FAME (Fatty Acid Methyl Ester) analysis based on AOAC Official Method 996.06 section G.

Simple analysis of preservatives using a Thermo Scientific Hypersil GOLD HPLC column

Instrument Type: HPLC

The preservatives potassium sorbate (E202) and sodium benzoate (E211) were extracted from mayonnaise and separated using a Thermo Scientific Hypersil GOLD HPLC column in less than 10 minutes.
