Free CFS Food Science Fundamentals Questions and Answers

Question 1

What is the role of carbohydrates in food?

Accepted Answer

To provide energy

Answer

Carbohydrates are the body's primary and most readily available source of energy. When consumed, they are broken down into glucose, which cells use for fuel to power all bodily functions, from basic metabolism to physical activity. This makes them a fundamental macronutrient essential for daily life.

Question 2

What is the difference between essential and non-essential amino acids?

Accepted Answer

Essential amino acids must be obtained from food

Answer

Essential amino acids are those that the human body cannot synthesize on its own and therefore must be acquired through dietary intake. In contrast, non-essential amino acids can be produced by the body from other compounds. Both types are crucial building blocks for proteins, which perform numerous vital functions in the body.

Question 3

Why is water an essential component of food science?

Accepted Answer

It is essential for cooking, digestion, and nutrient transport

Answer

Water is a fundamental solvent and reactant in food science and biology. In food, it's vital for cooking processes and texture, influencing how ingredients interact. Within the body, water facilitates digestion by breaking down food, transports nutrients to cells, and helps remove waste products, making it indispensable for life.

Question 4

What is the role of vitamins in food?

Accepted Answer

To regulate bodily functions

Answer

Vitamins are organic compounds required in small quantities for various metabolic processes and overall health. They act as coenzymes or cofactors, helping enzymes perform their functions, which include regulating growth, immunity, energy production, and nerve function. Unlike macronutrients, they do not provide energy directly but are vital for bodily regulation.

Question 5

What is food fortification?

Accepted Answer

Adding nutrients to improve food's nutritional value

Answer

Food fortification is the practice of deliberately increasing the content of essential micronutrients, such as vitamins and minerals, in a food. This process aims to improve the nutritional quality of the food supply and address specific public health nutritional deficiencies within a population. It helps enhance the overall health benefits of commonly consumed foods.
