Ultrasonic Humidifier

Dates are subjected to postharvest losses in quality and quantity caused by water loss, fermentation, insect infestation, and microbial spoilage during storage. Cold storage is the main element in the postharvest quality management used for fruit preservation. Although cold storage is used for dates, precision control of the relative humidity (RH) using ultrasonic applications is not used thus far, or it is applied to other fruits on a small scale. Therefore, we designed and constructed an ultrasonic humidifier (DUH) for RH control in the cold storage room (CSR) of dates. The optimum air velocity of 3 m s−1 at the outlets of the DUH ducts produced a mist amount of 6.8 kg h-1 with an average droplet diameter of 4.26 ± 1.43 µm at the applied voltage of 48 V and frequency of 2600 kHz of the transducers. The experimental validation was carried out by comparing a CSR controlled with the DUH with two conventional CSRs. The three tested CSRs were similar in dimensions, cooling system, and amount of stored dates. The time required for cooling 800 kg of dates in the controlled CSR from 25 °C to the target temperature of 5 °C was approximately 48 h. The DUH precisely controlled the RH at the maximum RH set point of 80% in the tested CSR at 5 °C. The controlled RH at 80% has a positive impact on the physicochemical characteristics of the stored dates. It significantly reduced the weight loss of the fruits and preserved fruit mass, moisture content, water activity, firmness, and color parameters. However, no significant effect was observed on fruit dimensions, sphericity, and aspect ratio. The microbial loads of mesophilic aerobic bacteria, molds, and yeasts fell within the acceptable limits in all tested CSRs. Both stored date fruits and artificially infested dates showed no signs of insect activity in the controlled CSR at the temperature of 5 °C and RH of 80%. The DUH proved to be a promising technology for postharvest quality management for dates during cold storage.

Third Instar Larvae

AbstractAll codling moth larvae, Laspeyresia pomonella (L.), in 100,000 infested apples were killed by fumigation with 32 g/m3 methyl bromide for 2 h at about 17 °C followed by 31–35 days of storage at −0.5 °C. The apples were harvested into bins, fumigated, and placed in a standard cold storage room of a grower’s packinghouse as would be done under commercial conditions. Standard cold storage killed all first and second, and some third, instar larvae in nonfumigated fruit. Cursory sampling indicated that fumigation alone, without subsequent cold storage, could kill all stages. The fumigation and storage treatment did not injure Red Delicious, Golden Delicious, Spartan, Jonathan, or Newtown apples.

Ethylene Level

Ozone at the concentration of 0.04 mL L–1 appears to have potential for extending the storage life of broccoli and seedless cucumbers stored at 3°C. Response to ozone was minimal for mushrooms stored at 4°C and cucumbers stored at 10°C. Ozone generators producing 0.04 mL L–1 ozone reduced the ethylene level in vegetable storage rooms from 1.5–2 mL L–1 (as produced by apples placed in the room) to a non-detectable level. At concentrations of 0.4 mL L–1, ozone was effective in removing ethylene from the atmosphere in an apple and pear storage room. The ozonized and non-ozonized apples and pears showed no difference in fruit quality. This study explored a potential use of ozone application in wholesale storage rooms where ethylene-producing and ethylene-sensitive fruits and vegetables may be stored together.

In studies with a small scale cold storage room of ordinary type a relation was obtained between coil area and temperature of brine for a constant room temperature and given outside conditions. The dehydrating effect in the room was found to decrease as the cooling coil area was increased. As the evaporating area of stored material was increased the dehydration per unit area was found to decrease slightly, and at different temperature levels the dehydration for a constant temperature difference between inside and outside air was found to correspond closely to the capacity of air for holding moisture at the respective temperature levels.

Effect of PE materials on environmental temperature, frost accumulation and electricity consumption of mini store-room prepared with the new type foamed polyethylene was investigated. The application of portable mini cold storage room made of this material on the quality of “Fuji” apples was also studied. The fruits of apples had good quality after 150 days storage. Our findings reveal that soft foamed PE insulation material has a good potential to prepare mini store-room for the preservation of fruits.
