Storage of apricots in modified atmospheres.

Results are given from experiments carried out during 1996-97 in New Zealand investigating the storage of apricots in modified atmospheres (MA). In trials in 1997, fruits of cultivars Sundrop, Valleygold and CluthaGold were stored in air or in sealed standard 30 micron LDPE plastic, perforated or mineral coated (activated earth) plastic bags for 3 or 5 weeks (Valleygold) or 4 or 6 weeks (Sundrop and CluthaGold) at 1-2 deg C. After storage fruits were placed at 20 deg for 5 days before being assessed their external and internal appearance, mealiness, flavour, firmness, soluble solids, postharvest rots and percentage weight loss. After 5 weeks in storage, fruits stored in MA showed changes in skin colour, developed a dull finish and lost the glowing colour and skin sheen seen on the controls. Fruit skin was pocked and fruits had more postharvest rots than controls. The flesh of stored fruits was darker and more translucent than that of controls, with a firm, rubbery texture, low soluble solids and

 unacceptable flavour. Weight loss after 5 weeks in storage was significantly lower in MA than in air. It is concluded that storage in air is satisfactory for 3-4 weeks, but neither MA bags nor air storage produced acceptable fruits after 5 weeks.
