AbstractTomato fruit cv. ’Faustine’ F1were harvested at mature green and full-red stages and treated with 1 or 2 µl·l−1of 1-methylcyclopropene (1-MCP) at 20 °C and 85-90% RH, for 21 hours to investigate the ability to delay ripening. Treated and control fruit were stored at 12.5 and 20 °C and 85-90% RH. Ethylene production, rate of respiration, weight loss, market value and storage life were determined after 4-week storage. Exposure of tomato fruit to 1-MCP reduced ethylene production and respiration rate of the fruit harvested at mature-green and full-red stages of maturity. Storage life and market value of tomato fruit depended on the treatment with 1-MCP, stage of maturity and storage temperature. Untreated fruits were characterized by the shortest storage life in comparison with the fruit treated with 1-MCP. The lowest market value was observed for tomato fruit harvested as a mature green, untreated with 1-MCP and stored at 20 °C. Treatment of tomato fruit with 1-MCP resulted in the reduction of natural weight loss during storage. These results suggest that 1-MCP treatment can be used in a commercial storage and trading system for tomatoes due to its ability to delay fruit ripening.

The influence of short anoxia treatment on physical, chemical and sensory attributes of mature green and pink red tomatoes during storage was investigated. Matured green and pink red fruits were kept for 24 hrs under humidified pure N2, while the control was not treated. Subsequently, the fruits were stored at 12?C and 20?C for 14 days. Quality parameters including weight loss, firmness, total soluble solids, colour, sensory and decay were analyzed. Generally, weight loss increased after 14 days of storage and depending on anoxia treatment, maturity and storage temperature. Tomato fruit treated with anoxia and kept at 12?C showed a minimal deterioration of the quality attributes and could be stored for longer periods compared to those stored at 20?C. Results for TSS were higher in tomato fruit treated with anoxia. However, pink red fruit stored at 20?C showed lower TSS than untreated fruit. Untreated and anoxia-pretreated mature green tomatoes showed higher sourness and off-flavour scores than those stored at 20?C. However, mature green and pink red tomatoes kept at 20?C showed higher acceptance (%) than those stored at 12?C. Therefore, combined effect of anoxia and low temperature could have delayed the ripening of the tomatoes.

The effects of growing and storage locations and storage temperature on soft scald incidence of `Honeycrisp' apples were examined. In 1999 and 2000, fruits were produced at five different locations, harvested at two different times, and stored at two or five different storage locations. In 1999, fruits were stored at 0 or 2 °C. Soft scald was only observed in fruits from one growing location and primarily at 0 °C. More soft scald was observed from the second harvest than from the first. Scalded fruits were preclimacteric as determined by ethylene production rate, whereas fruits from the other locations were postclimacteric. In 2000, fruits from four of the growing locations developed soft scald, and soft scald incidence was not related to ethylene production rate. Scalded fruits had higher concentrations of phosphorus, boron, and magnesium, and lower concentrations of manganese than unaffected fruit. Development of soft scald was not related to fruit ethylene production rates, was dependent on growing location, increased with later harvest, and may be related to fruit elemental content.

Storage Temperatures

The effect of storage temperature on the shelf life, weight loss, respiration rate and ethylene production of Hass avocado (Persea americana Mill) was studied. Two batches of green mature avocado fruits, classified as ‘‘super extra’’ were stored at 10 and 20 C (first batch) and at 7 and 25 C (second batch). The avocado shelf lives were 22, 8, 32 and 6 days at 10, 20, 7 and 25 C, respectively. Based on the data of the first assay Q10 was calculated as 2.75, with this value the predicted shelf life at 7 and 25 C were 29.8 and 4.8 days, respectively. That meant shelf life was underestimated 7 and 20% at 7 and 25 C, respectively. Weight loss was linear at both the storage temperatures, it was 4.3% in fruits at 20 C for 8 days and 3.0% at 10 C for 22 days. The maximum CO2 production at 20 C was reached during the second day of storage, while at 10 C it was reached at the 17th day (176.17 15.98 and 74.73 7.32 mL/kg h, respectively). The maximum ethylene production at 20 C was reached the second day of storage, and at 10 C the 6th day (239.06 54.55 and 28.00 8.12 mL/kg h, respectively).

Mangifera Odorata or locally called Kuini, is a mango species with attractive striking orange flesh and have strong and unique smell, make it special in local market. Research is being carried out in MARDI from seed production to marketing to expose M. odorata to local and export market. Postharvest handling technology is one of importance aspect that has been develop to cater the market needs for commercialization. Proper postharvest handling will reduce postharvest losses, maintain freshness and to prolong storage life to make sure consumer get the premium quality of fruit. In postharvest handling, one of most important factors to maintain quality during handling, distribution and display is storage at the optimum temperature. Effect of different storage temperature on quality and storage life of M. odorata var. Tembaga were carried out. M. odorata at 11 to 12 weeks after fruit set were harvest at MARDI Sintok, Kedah and transported to packinghouse MARDI Serdang for storage study. On arrival at MARDI Serdang, fruit were sorted, washed, drain, packed and stored at different storage temperature (8, 10, 13, 15 and 250C). Visual quality assessment (appearance, disease quality changes), physical (texture, colour (Lightness, hue, chroma)) and chemical (pH, total titratable acidity (TTA), ascorbic acid, soluble solid content (SSC)) analysis were carried out weekly. Results of this study showed that storage duration and different storage duration significantly affected SSC. pH, TTA, chroma of M. odorata. The highest TSS, pH and chroma of M. odorata at 100C and the lowest at 250C. The highest TTA of M. odorata at storage temperature 80C and 130C, and the lowest TTA at 250C. Ascorbic acid content not significantly affected by different storage temperature from 8 to 150C, but significant different compare to ascorbic acid content at ambient storage temperature. Ascorbic acid content of M. odorata significantly lower at 250C compare to storage at 8 C - 150C. Lightness and texture of M. odorata slightly decrease during storage but not significant (P>0.05). Lightness of M. Odorata was not significantly affected by different storage temperature. Hue of M. Odorata significantly affected by storage duration and but not affected by different storage temperature. Hue of M. odorata significantly increased in the first weeks of storage, followed by significant decreased at week 2, maintain until week 4 and significantly decreased at week 5. Quality observed visually showed that freshness of M. Odorata maintain 5 weeks at 80C, 4 weeks at 100C, 2 weeks at 10 – 150C and 1 week at 250C.

The storage life of blackberry fruit is generally `2 to 3 days when stored at 1C. This study was done to determine the maximum storage life among erect blackberry cultivars, and to determine storage temperature effects on storage life. Shiny black fruit from `Navaho', `Arapaho', and `Shawnee' cultivars were stored at 2C, 5C, or 10C for 20, 14, and 7 days, respectively. At any temperature. only 10-20% of `Navaho' fruit had decay, while 30-50% of `Arapaho' and 40-70% of `Shawnee' fruit had decay. Weight loss was 3-5% depending on temperature and was not different among cultivars. Soluble solids concentration did not change during storage but titratable acidity decreased in all cultivars for fruit held at all temperatures. Anthocyanin content increased during storage in `Shawnee' and `Navaho' but not in `Arapaho' fruit. Results indicate that `Navaho' fruit have a longer shelflife than other blackberry cultivars.

Okra pods are highly perishable due to a high respiration rate and chilling sensitivity. The purpose of this experiment was to evaluate okra cultivar response to package and storage temperature. Freshly harvested `Annie Oakley', `Blondy', `Burgundy', `Clemson Spineless' and `Emerald' okra pods were placed in plastic boxes and shrink-wrap bags. Pods were evaluated for weight loss, chilling injury and electrolyte leakage during 8 days of storage at 12.5 and 3°C. Weight loss was similar for all cultivars at both temperatures, but it was much less when pods were stored in bags compared to boxes. Percent electrolyte leakage was similar for all cultivars before storage. `Blondy' displayed the most severe chilling injury after 8 days of storage at 3C while `Emerald' had few symptoms of chilling injury. After 8 days of storage, all cultivars except `Emerald' had increased electrolyte leakage. These results indicate that okra pods have increased membrane permeability with chilling injury, and the degree of chilling injury may differ with cultivar.

To study ripening-related chilling injury in pepper (Capsicum annuum L.), chilling-tolerant ‘Buchon’ and chilling-sensitive ‘Nockgwang’ fruit were harvested at mature green (MG), breaker (BR), and red-ripe (RR) stages and stored at 1, 5, and 10 °C for 21 d. ‘Buchon’ did not show surface pitting (SP) regardless of ripeness stage and storage temperature, whereas ‘Nockgwang’ at MG and BR exhibited SP at 1 and 5 °C. After 14 days of storage at 1 °C, chilling-sensitive ‘Nockgwang’ did not show SP when fruit were at the RR stage. Compared with ‘Buchon’, ‘Nockgwang’ at MG and BR had more electrolyte leakage increase during storage at 1 and 5 °C. ‘Buchon’ at all ripeness stages showed significantly higher ethylene production during storage regardless of storage temperatures. Contents of β-carotene and lycopene increased in both cultivars as ripening progressed. The contents of β-carotene and lycopene were similar between the two cultivars regardless of storage temperatures and ripeness stages. Susceptibility of pepper fruit to chilling appeared to be related to superoxide dismutase (SOD) and catalase (CAT). Activities of SOD and CAT were much higher in ‘Buchon’ than ‘Nockgwang’, more apparently at MG and BR. The results suggest that chilling-tolerant ‘Buchon’ and fruit at RR could have been equipped with a more efficient antioxidizing system, even if it was not clear whether oxidative stress is a cause or an effect of the CI in pepper.
