NO

STEM END CAVITY occurs at the stem end of the fruit, starting with watery patches in the flesh and discoloured strands. As it progresses, the flesh collapses, forming a distinct cavi ty, often with grey-brown surrounding tissue. Irregular tissue strands may be present within the cavity. External symptoms are visible only in severe cases when the cavity reaches the under-surface of the skin. This disorder may be linked to physiological and nutritional imbalances, possibly from low calcium or high nitrogen, or harvesting over-mature fruit. JELLY SEED is similar to soft nose but occurs when the flesh around the seed ripens faster than the rest of the fruit. There are no visible symptoms on the outside of the fruit, but the flesh often has an ‘off’ odour and flavour. This condition is thought to have similar causes to soft nose, likely linked to factors such as inadequate nutrition or excessive veg etative growth during fruit development.

NO

NO

SOFT NOSE occurs when the flesh near the nose of the fruit ripens more quickly than the rest, becoming over-soft, dark yellow, and watery. In severe cases, the flesh around the seed also becomes overly soft, known as jelly seed. The skin around the nose turns yellow before the rest of the fruit. While the exact cause is unclear, it may be linked to a nutritional imbalance or harvesting over-mature fruit.

NO

FLESH BROWNING is characterised by dark brown discolouration, often starting as small dark spots near the seed. In severe cases, it can cover over 50% of the flesh. This condition is believed to be associated with prolonged storage times or a combination of short stor age with excessive delays (several days) between harvest and the start of cold storage.

NO

FLESH CAVITIES are areas of empty space within the fruit, which can appear anywhere in the flesh. These cavities may have a white border around them. They are typically caused by impact damage, such as when fruit is dropped onto a hard surface, or by exposure to hot water treatment.

NO

WHITE PATCHES in the ripe flesh can appear as small rice-sized spots, streaks, or larger areas. These patches are typically firmer than the surrounding flesh. Ricey spots are often caused by damage during heat treatment for disinfestation, while streaks and larger areas are usually the result of impact damage. In some cases, these areas may also contain cavities due to the impact.
