Can You Taste With a Plugged Nose? How Smell Affects TasteFeatured science projectScience project video

Procedure

1. Ask your volunteer "taster" if they have any food allergies and if they mind being blindfolded. Modify as necessary.

2. Keep all baby food samples hidden from view of the tasters. Loosen the lids prior to beginning, but do not remove the lids until the volunteer has their nose plugged.

3. Blind fold the volunteer with the bandana (or ask them to keep their eyes shut) and place nose plugs on their nose (or have them plug their nose by pinching it with their fingers). Tell the volunteer they need to remain blind folded with their nose plugged while they taste five (5) different types of baby food.

4. With a clean spoon, give the volunteer (blindfolded and with nose plugged) about a half a spoonful of baby food. Ask them what they think it is. Record the response as a yes or no in the table below on the paper:

peas

carrots

peaches

pears

turkey

Taster #1 blindfolded and nose plugged

Taster #1

only blindfolded

Taster #2

blindfolded and nose plugged

Taster #2

only blindfolded

Taster #3

blindfolded and nose plugged

Taster #3

only blindfolded

5. Repeat with all five (5) types of baby food for all three (3) "tasters" with blindfold and nose plugged. Do not record the responses of anyone who sees or knows what kind of baby food there is. Anyone who knows may be able to determine the flavor because of the texture.

6. Remove the nose plug and repeat step #3-#5 with each baby food type while the taster is still blindfolded.

7. Evaluate which types of baby food was the easiest and which type was the most difficult for the tasters to identify.

    Safety concerns:
    Take into consideration food allergies and ask your "tasters" about any food allergies they have. Also, be considerate that some people do not like to be blindfolded. If a volunteer does not want to be blind folded, have them close their eyes. Be sure to use a clean spoon for each sample being tasted.
