RETARDING DETERIORATION OF TABLE GRAPES WITH IN-PACKAGE SULFUR DIOXIDE GENERATORS WITH AND WITHOUT REFRIGERATION

An active packaging film (APF1) with releasing low concentration sulfur dioxide (SO2) was tested on quality of ‘vitis labruscana kyoho’ table grape. All samples were stored at 5°C and during the storage period the main quality parameters, weight loss, berries shatter, decay, firmness, total soluble solids content (TSS), total acid (TA, using the PH of grape juice instead of the TA ), Vitamin c (Vc) content were monitored and compared with the control sample unpacked in any film. Results demonstrated that APF1 could reduce water loss of table grapes, prevent it from pathogens infection. The results also showed that APF1 could greatly guarantee a long shelf life for grape. After storage 56 days (storage at 0~5°C), the water loss, berry firmness, TA and Vc content in grapes packaged in APF1 were slowly reduced, TSS was slight increased, percentage of shatter and decayed berries of grapes were 22% and 27%, respectively. The percentage of berries decay of grapes packaged in APF1 was reduced to 5% from 21% for control batches on 11th days. All unpackaged table grapes (control batches) were decayed after 28 days. APF1 would help to preserve quality and extend shelf life of table grapes.

Table grapes cvs. Flame Seedless, Black Monukka and Canadice were fumigated with 2 levels of Deccodione smoke tablets for 30 minutes. Grapes were packed in TKV lugs with Botrytis inoculum planted among the clusters and stored at 0° C for up to 9 weeks. Size of smoke particles was determined. Fruit was evaluated at weekly intervals for decay and quality parameters. Deccodione residues on fruit were determined and found to be within acceptable limits set for this chemical. It was possible to store the grapes for up to 4 weeks at 0° C in good condition. Beyond this period effect of fumigation was lost. There was no bleaching of pigments around the capstem as is seen with sulfur dioxide fumigation. Storage for prolonged periods will necessitate increasing the dose of Deccodione tables and/or repeating the fumigation.

And Control

Fruit of Vitis vinifera cvs. Flame Seedless, Thompson Seedless and Black Monukka were fumigated with 4, 6 and 8 Deccodione Smoke Tables (DST) for 30 minutes. Fruit was stored at 32 F and high relative humidity. Decay control index, freshness of stems and bleaching around the capstem were recorded at 4, 8, 12 and 16 weeks of storage. Size of the aerosol particles was determined using an electrical aerosol analyzer. Fruit was analysed for Deccodione residues. Lower rates of the fungicide gave unsatisfactory decay control. Eight DSTs successfully controlled decay upto a period of 14 weeks. There was no bleaching of pigments commonly associated with sulfur dioxide fumigation. Majority of the aerosol particles were between 0.18 and 0.32 micrometers. Deccodione residues on the fruit were within the acceptable limits established for Deccodione. There was no perceptible difference in taste between treated and control fruit. This method of decay control could provide a viable alternative to sulfur dioxide fumigation.

A postharvest storage trial was undertaken to test the efficacy of 3 brands of dual-release sulfur dioxide (SO2) generating pads against Botrytis cinerea in stored table grapes (Vitis vinifera cv. Calmeria) and to determine if there were any detrimental effects (bleaching, SO2 residues) of the pads on table grape quality. The UVAGAS and UVAS Quality Grape Guard pads slowed decay development and the spread of botrytis rot, prevented naturally occurring infections, and retained stem freshness better than the SYS pad which is commonly used in the Swan Hill area. A properly working SO2 pad placed in the top of a 10-kg box was sufficient to control botrytis rot in table grapes even when moderate levels of initial inoculum were present. The results indicate that increased SO2 residues in fruit and bleaching of berries over time are more likely with increasing damage caused by B. cinerea. After 10 weeks, both inoculated and non-inoculated grapes stored with UVAGAS or UVAS pads were in sound and commercially acceptable condition. In contrast, SYS SO2 pads did not provide acceptable control of B. cinerea in Calmeria grapes.
