Stripping solvent of a meal is called ..........
Stripping solvent of a meal is called ..........
Show Hint
Desolventizer-Toaster (DT) is the most critical machine in an oil mill for meal quality. No Toasting = Toxic Hexane residues in the meal!

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
In solvent extraction of oilseeds (like soybean), after the oil is removed, the remaining solid "meal" is saturated with the solvent (usually hexane). This question asks for the technical term for removing this solvent.
Step 2: Detailed Explanation:
• The Equipment: The process is carried out in a "Desolventizer-Toaster" (DT).
• Process: The solvent-laden meal is heated with steam. This vaporizes the solvent (stripping), which is then recovered and reused.
• Technical Term: This combined process of solvent removal and heat treatment is called Toasting.
• Secondary Benefit: Toasting also serves an important nutritional role: it inactivates anti-nutritional factors (like trypsin inhibitors in soy) via heat, making the meal safe for animal feed.
• Other Options: Buttering and Jamming are culinary terms; Milling is the initial crushing, not the solvent removal.
Step 3: Final Answer:
Stripping the solvent from the extracted meal is professionally referred to as toasting.
