Caneberries, which include blackberries and raspberries, must be picked when the berries are ripe or nearly ripe to ensure quality. Their thin fruit skin, high respiration rate, and high ethylene production make these berries extremely susceptible to postharvest losses. Although both raspberries and blackberries are considered “soft” fruits, raspberries are slightly more perishable in nature. The raspberry fruit is susceptible to greater moisture loss and fungal infection because of its lack of an outer protective covering (cuticle) and the fact that the raspberry fruit is left with a cavity in the center when detached from the plant.
