Microwave Extraction of Plant-Based Food in Multiwave 5000 for the Determination of Fat Content according to Weibull-Stoldt
Microwave irradiation employing Rotor 20SVT50 allows for a simple one-pot procedure for hydrolysis and subsequent extraction of food samples to determine their fat content.
Determination of fat content of foodstuff is an important analytical task for the classification of the goods. The standard procedure is the method according to Weibull-Stoldt, comprising acid hydrolysis of the sample and subsequent extraction of the hydrolysate in a Soxhlet apparatus.
Especially the latter is a time consuming process and requires substantial amount of organic solvents.
With the rising interest in in healthy food and especially vegan diets, thorough investigation and sound knowledge of the nutrition facts of plant-based alternative products is required.
Herein we use various plant-based food samples to elaborate and highlight a one-pot procedure for the fat determination according to Weibull-Stoldt. The microwave-mediated parallel approach allows for increased throughput in the sample preparation for food analysis.
