Question

The cause of sweet taste in fruits is:
1. Maltose
2. Ribose
3. Lactose
4. Fructose
5. Glucose

Answer 1

Correct Answer - Option 4 : Fructose

The correct answer is Fructose.

• The cause of the sweet taste in fruits is Fructose.
• Fructose is a natural form of sugar, which is why fruits with large amounts of fructose taste sweet.
  • Fructose is an element that causes fruits to sweet in taste is a type of sugar which already present in the human body with glucose. 
  • The sweetness of fruits is influenced by the quantity and composition of sugars.
  • Higher contents of sugar in the fruit increases the sweetness of the fruit.
  • In fruit such as apples, peaches, and plums, the main sugars present are sorbitol, sucrose, fructose, and glucose.
• Hence, option 4 is correct. 

• The acidity of fruits is influenced by the content and composition of organic acids.
• The amount of each type of acid found in each fruit-
  •  For example, the dominant acid in apples, peaches, and plums is malic acid. 
• The balance between the sweetness and acidity of fruit based on the quantity and composition of their sugars and acids.
• It is important for developing a complex and interesting taste that will enhance fruit flavour.
• Maltose :
  • Maltose is a disaccharide formed by two units of glucose with the chemical formula C₁₂H₂₂O₁₁. 
  • In humans, maltose is broken down by maltase enzymes, producing two glucose molecules that can be further treated and can either be broken down to provide energy or can be stored as glycogen.
  • Maltose provides energy for the many bodily functions enabling us to perform our day-to-day tasks.
• Lactose :
  • Lactose is a disaccharide that contains units of galactose and glucose.
  • Lactose monohydrate is mainly present in milk and exists as a naturally occurring disaccharide.
  • It is slightly soluble in ethanol but quite soluble in water, white and odourless crystalline powder.
