Soxhlet extraction - Study guides, Study notes & Summaries

FOOD ANALYSIS EXAM 2 2024 WITH 100% ACCURATE SOLUTIONS Itemize the procedures that may be required to prepare a food sample for accurate fat determination by a solvent extraction method (e.g., Soxhlet method). Explain why each of these procedures may be necessary. (3) - correct answer Predrying sample - Fats cannot be efficiently extracted from moist foods with ethyl ether; ether saturated with water is inefficient for fat extractions; dried samples are easier to grind. Particle size r...

1. What are some important considerations in selecting solvents to be used in continuous, noncontinuous solvent extractions? – -High solvent power - low solvent power - evaporates easily - low bpt - inexpensive - nontoxic 2. To extract fat, use ethyl ether or petroleum ether as solvent and either Soxhlet or Goldfish what combo choose? - Petroleum Ether - more selective for hydrophobic lipids -less hydroscopic -cheaper Soxhlet - no channel -soaks sample -no heating sam...
