In the study, the effect of 1-methylcyclopropene (1-MCP), normal (NA) and modified atmosphere (MA) storage treatments were investigated on postharvest quality properties of freesia (Freesia sp.). Freesias harvested in the experiment were divided into two groups: the first group of samples was treated with 675 ppb 1-MCP, the other group was not treated with 1-MCP. Cover materials in different characteristics were used in MA. All of the samples were stored 14 days at 4 +/- 1 degrees C temperature and 80 +/- 5% relative humidity and some quality analysis was done in the samples taken from 0, 7 and 14 days. When the quality parameters used in the study were examined, 1-MCP delayed the opening of flowers in general, in NA and MA groups, and showed a mitigating effect on flower dumps. In the end of the study, the best results in terms of postharvest quality characteristics were obtained from 1-MCP and 50 mu PE combined treatment.
Effect of low-dose gamma irradiation on the quality of sweet cherry during storage
(Codon Publication, 2008) Akbudak, Bulent; Tezcan, Himmet; Eris, Atilla; Uludağ Üniversitesi/Ziraat Fakültesi/Bitki Koruma Bölümü.; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 56253171700; 7003481568; 6602612385
The efficacy of postharvest gamma irradiation treatment on sweet cherry cv. "0900 Ziraat" was tested under controlled atmosphere. Cherries were stored at six different atmosphere combinations for up to 60 days after being exposed to gamma irradiation. Weight loss values were higher in cherries stored under normal atmosphere compared to controlled atmosphere. Initial firmness was 14.21 and 15.97 N in non-irradiated and irradiated fruits, respectively. While the final values were 2.94 N in normal atmosphere and 5.49 N in normal atmosphere+gamma irradiation. The highest acidity and ascorbic acid values were recorded in the fruit stored under controlled atmosphere (20:5, 25:5)+gamma irradiation. Irradiation reduced spoilage from 25.06 to 5.00%. The fungi most frequently isolated from sweet cherries were Botrytis cinerea, Penicillium expansum, Monilinia fructicola, Alternaria alternata and Rhizopus stolonifer. Better fruit quality was obtained when controlled atmosphere was combined with gamma irradiation compared with either normal atmosphere or controlled atmosphere. Sweet cherry cv. "0900 Ziraat" can be stored successfully for more than 60 days under controlled atmosphere (20:5)+gamma irradiation and partially controlled atmosphere (25:5)+gamma irradiation conditions.
Effect of polypropylene and polyvinyl chloride plastic film packaging materials on the quality of 'Yalova Charleston' pepper (Capsicum annuum L.) during storage
(Japanese Soc Food Sci & Technology, 2008-01) Akbudak, Bulent; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 56253171700
The long pepper (Capsicum annuum L. cv. 'Yalova Charleston') was stored in plastic film with various oxygen (O-2) and carbon dioxide (CO2) permeabilities consisting of 7 +/- 1 degrees C temperature and 90 +/- 5% relative humidity (RH). Physico-chemical changes were recorded on 0, 10, 20 and 30 days of storage. Weight loss was higher in pepper stored under normal atmosphere (NA) compared to modified atmosphere packaging (MAP). Initial total soluble solids of 4.20% increased to 5.27% in NA. The acidity and ascorbic acid contents of peppers decreased during storage. The highest values were recorded at the end of storage from the fruit stored under PP (polypropylene). Changes in fruit color at the end of storage proceeded more slowly in the treated fruit. Total chlorophyll values exhibited significant decline in the fruits subjected to NA. However, the chlorophyll content in the fruits subjected to PP was low. The color values obtained from fruits supported the chlorophyll findings. At the end of the study, 35 mu PP packaging material gave the best result at the end of 30 day-storage with respect to the parameters evaluated in the study. Therefore, especially 35 mu PP treatment was effective with regard to delaying the maturity along the storage and fruit quality in peppers.
