Study Notes

Physiological Importance of Fragrance and Flavor Substances

Fragrance and flavor substances play crucial roles in influencing human emotions, enhancing food enjoyment, and triggering memory recall.
These substances can also stimulate appetite and digestion through olfactory and gustatory mechanisms.

Use of Fragrance for Humans

Fragrances are used to enhance personal appearance through perfumes, deodorants, and body sprays.
Aromatherapy employs fragrances for psychological and physical wellness, promoting relaxation and mood improvement.

Types of Flavor and Fragrance Products

Natural flavors derived from plant and animal sources.
Artificial flavors created through synthetic processes to mimic natural flavors.
Nature-identical flavors that chemically resemble compounds found in nature but are synthetically produced.

Problems Associated with Using Natural Flavors

Natural flavors may contain allergens that can affect sensitive individuals.
Variability in natural sources can lead to inconsistent flavor profiles and supply issues.

Locations of Receptor Cells for Flavor and Fragrance

Taste receptor cells are primarily located on the taste buds of the tongue.
Olfactory receptor cells are located in the nasal cavity, responsible for detecting airborne fragrance molecules.

Disadvantages of Using Natural Flavors

High production costs and limited availability can make natural flavors less economically viable.
Natural flavors can have shorter shelf lives, leading to potential spoilage.

Disadvantages of Using Imitation Flavors

Imitation flavors may lack the complex taste profiles found in natural flavors.
Regular consumption of artificial flavors may lead to negative health implications over time.

Advantages of Using Imitation Flavors

Cost-effective and reliable supply, often produced in large quantities without fluctuations.
Greater control over flavor consistency and longevity compared to natural counterparts.

Sources of Aromatics in Plants

Aromatic compounds are concentrated in essential oils, found in various plant parts like leaves, flowers, and barks.
Terpenes, phenolics, and other organic compounds contribute to the distinctive fragrances of plants.
