Freshness is most important but often neglected attribute

Lack of freshness in fruit-flavored or fruit food and beverages due to heat processing impairs the palatability of both full sugar and sugar-reduced products.

Aftertaste like bitter, tart, astringent & artificial off-notes, especially in sugar-reduced products using sweeteners, also gives an impact on the attractiveness of the products.

  • Refreshing mouthfeel

  • Pre-stored memory of experience

The top two freshness perception killers

  • Ambiguous or unrecognizable aroma

FRESHNESS
Aroma
Mouthfeel

The aroma (smell) is the first sensory attribute contributing to freshness, assessed by the perceived closeness of the smell to the perception of the original, unprocessed fruit.

Freshness also results from a mouthfeel that is described as mouth-watering.           

Freshness is the consequence of a flavor perception (processed sensory attributes) if all sensory signals point in a balanced, coordinated, and unambiguous way to the same stored image in our brain associated with freshness.                  

Why beverages lack freshness

Mismatch of aroma and taste, delaying the brain from rapid recognition of flavor

                               

Frequently beverages lack freshness due to a mismatch of aroma and taste. Any mismatch creates ambiguity and prevents an early and clear flavor recognition which is important for freshness perception

 

Even subtle mismatches cause ambiguity and delay in recognition but are much more difficult to improve.
