Sensorial and Nutritional Properties of a Collagen-Fortified Snack Bar Designed for the Elderly.

Background: This study aimed to develop a highly consumable collagen-containing bar that contributes to enriching the diets of elderly individuals, in terms of energy and nutrients.

Method: For this purpose, five different bar samples (C, P1, P2, D1, D2) containing different amounts of collagen, date puree, and pumpkin puree were developed and subsequently evaluated in terms of their sensory and nutritional properties by a panel of 30 adult trained sensorial analysists.

Results: The bars with the highest flavor score were those with high levels of collagen and pumpkin puree (P2) and date puree (D2).
