Suitability for freezing — Rubus idaeus L. x Rubus subg. Eubatus Focke

An anatomical feature of the loganberry is that the receptacle remains inside the fruit upon harvesting, which distinguishes the hybrid from raspberry, where the fruit remains hollow. This affects the physical characteristics of the berry during storage at low temperatures.

The flesh texture of the hybrids is characterized as moderately firm and juicy. When overripe, the fruits are prone to losing their shape and softening, so the final quality of the frozen product directly depends on the degree of maturity of the berries at the time of harvest, which requires special care during preparation for freezing.
