Postharvest characteristics and consumer acceptance of non-melting peaches.

In 1997 and 1998, non-melting and melting clones of peach (Prunus persica) from the University of Florida Prunus breeding programme (USA), were compared for postharvest quality characteristics including blush and ground colour, flesh firmness, percent soluble solids, and acidity. Fruits were harvested and stored at 0 deg C for 14 days. After cold storage, fruits were analysed immediately (1998), or held at 20 deg C for 3 days before postharvest quality analyses were conducted (1997). 'UFGold' (a non-melting flesh cultivar) was similar, or slightly superior, to 'Flordaprince' (a melting flesh cultivar) for blush and ground colour, and acidity. Soluble solids were higher for 'UFGold' than for 'Flordaprince' in both years. Non-melting flesh clones had much firmer flesh after storage than melting flesh clones. Consumer acceptance trials for melting (AP93-2 and 'Flordaprince') and non-melting clones (92-10C and 'UFGold') were conducted at a local supermarket during 1997 and 1998. One-hundred (1997) o

r fifty (1998) consumers were surveyed over a 2-day period. The non-melting flesh clones rated higher than the melting flesh clones for most consumer quality assessment characteristics including texture, appearance, and overall quality.
