Extending Shelf Life of Fresh-Cut Persimmon by Honey Solution DipsJournal of Food Processing and Preservation, Volume 34 Issue 1, Pages 2 - 14
Ripe persimmon fruit (Diospyros kaki L) cv. "Hachiya" were diced, then treated with 10–20% w/v diluted honey solution or water as the control, followed by cold storage at 4C until loss of acceptable quality. The persimmon cubes were subject to assessments during the storage of organoleptic and visual quality, softness and exuding juice, soluble solids content (SSC), and absorbance at 436, 440, 675 and 760 nm, respectively.
Honey treatments prevented off-aroma development and delayed jelling. Softness and exuding juice of the fresh-cut persimmon cubes increased with time, with the increase in both parameters being significantly suppressed by honey solution dips. Changes in SSC, pH and the absorbance at 436, 440, 675 and 760 nm, respectively, during storage were minor and there was little effect of the honey treatments on these parameters.
Overall, the shelf life of fresh-cut persimmon cubes was extended by honey solution dips, which delayed off-aroma development, firmness loss and jelling.
PRACTICAL APPLICATIONS
New products and changing trends make today's food marketplace alive, and fresh-cut fruits and vegetables seem to be on top of list of these products. Although fresh-cut produce has been on the market for a long time, preserving their quality attributes has not been completely successful especially in the case of fruit. This study focuses on a new alternative fresh-cut produce, fresh-cut persimmon, with adapting a potentially safe organic method, use of honey dips.
The present study demonstrated that honey solution dip treatments could preserve the fresh-like quality of typical flavor or aroma of persimmon fruit by causing no changes in aroma and taste attributes and extending shelf life. Therefore, honey dip treatment may be used, depending on commodity, to preserve and extend shelf life of fresh-cut produce in fresh-cut processing industry.
