Video and lesson investigations on the topic of taste. Key concepts include:
- The choice of food may be affected by its color.
- People may have different preferences of color for certain types of food. Most foods have natural color.
- The color of food can be changed artificially with food coloring.
- In this sort of test, the results may not be the same every time.
- Taste buds are the receptors which determine our sense of taste.
- These are nerve endings (about 10,000 of them) found on the tip, sides and back of the upper surface of the tongue.
- Most experts use 4 taste receptors: sweet, sour, salty and bitter.
- Each kind of taste bud is grouped in a specific location on the tongue.
- For example, our ‘sweet’ taste buds are on the tip of our tongue, ‘salty’ on the side, ‘sour’ further back on the side, and ‘bitter’ right at the back of our tongue.
