This experiment was carried out during two successive seasons (2008-2009) and (2009-2010) on
Costata persimmon fruits (Disopyros kaki, L) harvested at mature stage. Experimental fruits were divided into
five similar groups; each of three boxes and each box about 2 kg. Fruits of each group were emulsified in one
of the following jojoba oil emulsion concentrations: 0, 25, 50, 75 and 100%. Treated fruits were stored at
13+1oC and 90% RH. Weight loss percentage, decayed fruits, changes in fruit weight loss, fruit firmness, flesh
SSC, total sugars, acid and vitamin C were evaluated at 7 days intervals. Jojoba oil emulsifying reduced weight
loss, decay fruit percentage. This beneficial effect was connected to oil emulsion concentrations; the high oil
concentration recorded the lower weight loss and discarded fruit percentage. Jojoba oil treatments increased
both fruit flesh firmness and acid content, since fruits treated with 100% concentration showed higher flesh
firmness and flesh acid values than the lower tested oil concentrations. Fruits received oil at 75% concentration
showed the lower total sugar content than those of the control. SSC of fruit was not much affected by all jojoba
oil concentrations. All treatments improved shelf live compared with the control. The percentage of natural
infection was increased with increasing storage period. In this concern, jojoba oil emulsion at 100% was the
effective preserving natural compound.
Key words: Cold storage, jojoba oil emulsion, persimmon, shelf life, , ,
