Q1. ________ is increasing the level of nutrients present to make the food a ‘richer’ source.

1. Enrichment
2. B. Restoration
3. Fortification
4. All of the above

ANSWER: A. Enrichment

• Explanation – Enrichment, restoration, and other related concepts are used in fortification. Enrichment refers to increasing the number of nutrients in food to make it a “richer” source. As a broad phrase, it has been frequently interchanged with restoration and fortification. Although there may not be a lot of distinction, they are defined for common understanding. Vanaspati, for example, is high in vitamin A. In this case, the concentration of a certain nutrient is increased to the required amount, and these enrichment programs are usually governed by government laws.

Q2. In case of radiation freeze-drying, the source of heating is _________ with the speed of vapor movement 1 m/s.

1. Infrared radiation
2. Ultraviolet radiation
3. Convective hot air
4. Metallic conduction

ANSWER: A. Infrared radiation

• Explanation – Infrared radiation from radiant heaters is utilized to heat shallow layers of food on flat trays, with an air movement of 1 m/s to ensure consistent drying. The infrared region of the electromagnetic spectrum is between visible light and microwaves, with wavelengths ranging from 0.5 to 100 meters. Near-IR (NIR), mid-IR (MIR), and far-IR radiation (FIR) are the three types of infrared rays.

Q3. Flour fortification with iron and folic acid, and salt iodization is an example of ________.

1. Mass fortification
2. Targeted fortification
3. Market-drove fortification
4. Bio-fortification

ANSWER: A. Mass fortification

• Explanation: The addition of one or more micronutrients to staple foods consumed by a population with an unacceptable public health risk of micronutrient deficiency is known as a mass fortification. Iron and folic acid fortification of flour and salt iodization are two examples. Governments normally lead them, but they can be voluntary or mandated, and they cover all sections of the community, including the most vulnerable.

Q4.  __________ is the increase of a level of a particular nutrient or group of nutrients, particularly micronutrients in food material to tackle some nutrition-related issues.

1. Fortification
2. Enhancement
3. Encapsulation
4. Incorporation

ANSWER: A. Fortification

• Explanation: The addition of one or more vital nutrients to a diet, whether or not they are ordinarily present in the food, to avoid or repair a documented shortage of one or more nutrients in the general population or specific demographic groups. To address some nutrition-related difficulties, fortification is the increase of a specific nutrient or collection of nutrients, notably micronutrients, in food material.

Q5. ________ is the process of increasing the density of vitamins and minerals in a crop through conventional plant breeding, using transgenic techniques, or agronomic practices.

1. Mass fortification
2. Bio-fortification
3. Targeted fortification
4. Food to food fortification

ANSWER:  B.  Bio-fortification

• Explanation – The process of enhancing the density of vitamins and minerals in a crop through conventional plant breeding, transgenic technology, or agronomic approaches is known as bio-fortification. Plants transport minerals from the earth to the crop’s edible section. Or, at the start of the value chain, synthesize the vitamins in the seeds before harvest. Researchers are attempting to boost the iron content of paddy using a genetic engineering strategy.
