1 How Do Our Senses Affect Food Choice?

2 Sensory Evaluation  Evaluating foods using each of our five senses:

3 Appearance (Sight)  Color: We have a preconceived idea of how food should look  Would you buy a steak that is brown and discolored?  Presentation: Using variety of colors on a plate and arranging food purposefully.

4 Odor (Smell) One of the main factors in determining whether or not you will even try a new food.

5 Flavor (Taste)  We sense flavor through taste & smell together  Our sense of smell has a huge influence on flavor  Have you ever noticed? When you have a head cold and your nose is all stuffed up, you can barely taste…

6 Flavor cont.  Flavor is sensed by your taste buds  Four Basic Flavors:  Sweet  Salty  Bitter  Sour  New 5 th Flavor:  Umami (Savory)  Where? Fun Fact taste buds renew every 3-10 days

7 Temperature (Taste)  Affects the flavor of food because it is influenced by volatile substances.  Volatile substances- The substance evaporates easily.

8 Temperature cont.  If the food is cold the flavors may not reach the nose. If a food is normally served cold and has been allowed to warm up the taste may be too strong.

9 Mouth Feel (Touch)  How food feels in the mouth  Examples: Crunchy, Creamy, Brittle, Tender Think about the way fat affects mouth feel – the difference between 2% milk and ice cream (10% fat)

10 Mouth Feel cont.  Texture  Graininess, Thickness, or Brittleness  Chewiness  Hard, Tough, Chewy, Tender, Very Tender

11 Sound  This can affect how you feel about the food while you are eating it  If you heard a crunch and shouldn’t have, or vice versa, would you lose your appetite?

12 Influences on Food Preference  Cultural Heritage: How your ancestors prepared food; based on what was/is available  Ex: Thai food uses a lot peanuts, rice, and curry powder – because those foods grow well in Thailand & are available in abundance

13 Influences cont.  Levels of Hunger: If hunger level is high, the human sensory level of food is lessened and there is more focus on the issue of survival  Tip: Never go to the grocery store while hungry!  Media/Advertising: National Brands highly advertised might be popular but are not actually better than the store brand. Our brain may subconsciously identify a well-known brand as better, affecting our perception  Brand Loyalty: Where you buy and what you buy because you know what to expect; you “trust” it

14 What’s your favorite food? Why?  5 foods you like and 5 foods you dislike  for each food you like, give a reason using at least 2 senses  For each food you don’t, give a reason using at least 1 sense  “Likes” Example  I like almonds because they are crunchy (mouth feel & sound), and have a light hint of sweetness (taste)  Taste (Flavor & Temperature),Touch (Mouth Feel), Sight, Sound, Smell
