HUMAN NUTRITION

Detailed explanation-1: -You can tell if food is still safe to eat by smelling it. FALSE: You can’t tell if a food is contaminated with harmful bacteria by looking at it, smelling it or tasting it.

Detailed explanation-2: -Food spoilage can be defined as a disagreeable change in a food’s normal state. Such changes can be detected by smell, taste, touch, or sight. These changes are due to a number of reasons-air and oxygen, moisture, light, microbial growth, and temperature.

Detailed explanation-3: -Nutrition. Odors are part of the flavor percept during food consumption (retronasal) (McCrickerd and Forde 2016; Small 2012), but more importantly, even before ingestion, odors can alert us to food in our environment and orient our appetite (McCrickerd and Forde 2016; Boesveldt and Graaf 2017).

Detailed explanation-4: -Sight. The human eye has an important role in the perception of colour, and this influences our idea of food flavour. Research shows that we associate specific colour perception of food with certain flavours (although tastes like bitter and sweet are not associated with a particular colour).
