Final answer:
An example of vitamin fortification is thiamin added to noodles, while niacin added to flour, vitamin C added to fruit drinks, and riboflavin added to white rice are examples of vitamin enrichment.
Step-by-step explanation:
An example of vitamin fortification rather than enrichment is thiamin added to noodles. Vitamin fortification refers to the addition of specific vitamins to a food product that may not naturally contain those vitamins. In this case, thiamin is added to noodles to enhance their nutritional value. On the other hand, vitamin enrichment refers to the addition of essential nutrients that were lost during processing.
An example of vitamin enrichment is niacin added to flour. Niacin is added to flour to replace the nutrients lost during the refining process. Similarly, vitamin C added to fruit drinks and riboflavin added to white rice are also examples of vitamin enrichment. An example of enrichment would be adding riboflavin to white rice, which restores the nutrient lost during the polishing process.
