Question:
Vegetable lecithin is obtained mainly from________
Vegetable lecithin is obtained mainly from________
Show Hint
Whenever "lecithin" is mentioned in a food label without a source, it almost always refers to Soy Lecithin. It is the gold-standard emulsifier for chocolate to control viscosity.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question asks for the primary botanical source of commercial vegetable lecithin used in the food industry. Lecithin is a mixture of phospholipids, primarily phosphatidylcholine.
Step 2: Detailed Explanation:
• Nature of Lecithin: Chemically, lecithin is a complex mixture of polar lipids (phospholipids and glycolipids) and triglycerides. It is widely used as an emulsifier, stabilizer, and wetting agent in chocolate, margarine, and baked goods.
• Industrial Source: While lecithin occurs in many plants and animals (like egg yolks), the vast majority of commercial vegetable lecithin is a byproduct of the refining of soybean oil.
• Processing: During the degumming stage of soybean oil refining, water is added to the crude oil, which causes the phospholipids to hydrate and precipitate. This "gum" is then dried to produce soy lecithin.
• Other Sources: Although sunflower and rapeseed (canola) lecithin are becoming popular as non-GMO alternatives, soybean remains the dominant global source due to its high phospholipid content and established processing infrastructure.
Step 3: Final Answer:
Soybean is the principal source of vegetable lecithin. Hence, option (B) is correct.
