What Consumers Like about Fresh-Market Blackberries

At the University of Arkansas System (UA System) Division of Agriculture, 80 consumers looked at and tasted fresh-market blackberries to help us determine attributes they liked. The consumers looked at individual blackberries and preferred oblong, large blackberries as opposed to round or small (see the figure below).

Consumers also looked at blackberries in clamshells and preferred to purchase clamshells containing larger blackberries or clamshells without blackberries with red drupelet reversion (see the Figure below).

Percent of consumers (n=81) that ranked clamshells of blackberries as most preferred for different size berries (A)z and different amounts of red drupelet reversion (B)y.
z Clamshell ‘735’ had about 22 10-g to 12-g berries, and ‘916’ had about 50 4-g to 5-g berries.
y Clamshell ‘942’ had 0% of the blackberries with red drupelet reversion, ‘516’ had about 25%, and ‘378’ had 65%.

Consumers then tasted six UA system cultivars (Caddo, Natchez, Osage, Ouachita, Ponca, and Prime-Ark®Traveler) and liked Ponca, Osage, Caddo, and Natchez the most. Ponca (10% soluble solids and 0.8% titratable acidity) was highly rated for sweetness, overall flavor, and overall impression. Understanding what consumers like about fresh-market blackberries provides blackberry breeders and blackberry growers with information to advance retail sale. — By Renee Threlfall, Research Scientist, Dept of Food Science, University of Arkansas
