Glucose syrup is commonly made from:

The correct answer is Maize because it serves as the primary commercial source raw material for industrial glucose extraction through starch hydrolysis.

• Maize: This is the correct choice. In commercial production, starch is extracted from corn (maize) kernels and treated with acids or food-grade enzymes to break down the complex polysaccharides into simple sugars, resulting in what is globally known as corn syrup or liquid glucose.
• Incorrect Options:
  • Sugar Cane / Beetroot: These are incorrect. While these agricultural plants are the world's primary sources of sucrose (standard table sugar), they are not the typical baseline materials processed to manufacture industrial glucose syrup.
