Acetone, ethanol, and Petroleum ether are commonly used in the extraction of carotenoids from tomato paste because they are organic solvents that are effective in dissolving and extracting lipophilic compounds like carotenoids. Each of these solvents has specific properties that make them suitable for different stages of the extraction process:
1. Acetone is often used as an initial solvent for extraction because it has a high affinity for carotenoids and can effectively break down cell walls and extract the pigments from the tomato paste.
2. Ethanol is commonly used as a solvent for extracting carotenoids because it has good solubility for these compounds and is relatively less toxic compared to other organic solvents. It can also help in removing impurities and other unwanted compounds during the extraction process.
3. Petroleum ether is often used as a final solvent for the purification of carotenoids extracted from tomato paste. It has a low boiling point and high volatility, which makes it easy to remove from the extract through evaporation. Additionally, Petroleum ether is non-polar and can effectively separate carotenoids from other polar compounds present in the extract.
Overall, using a combination of these solvents in the extraction process helps to achieve a high yield of pure carotenoids from tomato paste.
