    Notes: Objective quality of ultrafiltered (UF) apple juice compared favorably to apple juice filtered by conventional plate and frame filtration (PF). Agtron red and green values were higher for the UF juice, indicating a lighter colored product. Agtron green values were lower after 4 months of storage and compared well to juice from conventional methods over the remaining 8 months of storage. Green color of the UF juice remained steady at storage temperatures of either 1° or 21°C and was equal to the color values of the conventional juice stored at 1°, 21° or 32°. Clarity of the UF juice was excellent and remained stable over the entire storage period at either 1 or 21° with only a slight drop in clarity at 32°. UF juice was rated significantly lower in sensory flavor than PF juice. Sensory color of the UF juice was not rated as high as the PF juice at the start of the study, but as time in storage progressed sensory color improved. Initial panel reaction to UF apple juice was that the UF juice was too light in color and watery in flavor.

    Notes: The storage quality of‘Delicious’ apples individually packaged in rigid film containers was investigated. Objective quality attributes (internal and external color, firmness, soluble solids and titratable acidity) were measured as a function of storage time with and without packaging in a rigid container. Overall firmness, acidity and soluble solids content decreased over a 70-day storage period. Significant effects of rigid film packaging and storage included: superior skin color, decreased weight loss, slight decrease in soluble solids content and increased firmness loss during ripening when compared to control fruit. Upon examination of the atmosphere surrounding individual fruit in these containers, increased levels of carbon dioxide and ethylene were found. Conversely, packaged fruit contained significantly less internal carbon dioxide than control samples. It was concluded that the atmosphere modified by the rigid film container hastened ripening of‘Delicious’ apples, thus deteriorating eating quality. An adequately ventilated packaged would probably alleviate this condition.

    Notes: Quarantine regulations require domestic cherries exported to Japan be treated to control for codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae). The current procedure, methyl bromide fumigation, uses a restricted chemical, reduces fruit quality, and involves health, safety and environmental concerns. Single and double hot water dips were evaluated using fresh ‘Bing’ and ‘Sweetheart’ sweet cherries from Washington state as a potential replacement. The double dip procedure had a pretreatment bath at 40C for 5 min. For both procedures, submersions in heated water from 48 to 55C for 2–14 min were examined for treatment efficacy against third-instar codling moth and fruit quality. Although a 100% mortality response was found for each temperature and procedure, the submersion durations significantly damaged fruit and stem parameters for both cultivars. Thus, hot water dips are not feasible for Pacific Northwest cherries at this time.

    Notes: Abstract Response of white-fleshed peaches (‘Sugar Lady’, ‘Snow Giant’, ‘White Lady’and ‘Snow King’) and nectarines (‘Arctic Queen’and ‘Arctic Rose’) to controlled-atmosphere (CA) storage is cultivar dependent. Samples of fruit of these six cultivars were collected just prior to commercial harvest and held in either regular-atmosphere (RA) storage at 1C or controlled-atmosphere (CA) storage at 2% O2 and 6, 12 or 18% CO2, all at 1C. Four of the six cultivars (‘Snow Giant’, ‘White Lady’, ‘Snow King’and ‘Arctic Queen’) displayed excessive internal browning and poor flesh color after only 30 days of storage and should not be considered for long storage (+30 days). While ‘Sugar Lady’and ‘Arctic Rose’performed better and are possible candidates for CA storage, they should not be stored more than 45 days after harvest. The value of CA storage to extend the marketing of white-fleshed peaches and nectarines is questionable at best. If CA storage is to be used for storage-life extension of white-fleshed peaches and nectarines, O2 level should be maintained at 2% or less and CO2 level maintained at 12% or higher.

    Notes: ‘Bosc’pears (Pyrus communis L.) were placed in a purge-type controlled–atmosphere (CA) storage immediately after harvest (〉24 h) and held for 180 days at 1C. Oxygen in all atmospheres was 1.5% and CO2 was 1%, 3% or 5%. Pears were evaluated immediately after removal from CA storage and after ripening for an additional 7 days at 21 C. Pears stored in 3% CO2 were firmer, had a superior finish, with significantly reduced decay and internal breakdown than pears stored in 1% CO2. In 3% CO2, pears retained the ability to ripen after long-term storage. A 10 day delay in atmosphere establishment had little or no influence on the long-term keeping quality or ripening ability of ‘Bosc’pears. Firmness, soluble solids content and starch either alone or together were good indices of maturity for ‘Bosc’ pears.

    IRRADIATION AS AN ALTERNATIVE TO METHYL BROMIDE FOR QUARANTINE TREATMENT OF STONE FRUITS (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food quality 21 (1998), S. 0

    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Irradiation can be used with cherries, apricots, or peaches as a quarantine treatment at 300gy's or less with little quality loss. Either irradiation or methyl bromide (MeBr) can be used as a quarantine treatment for ‘Bing’‘and ‘Rainier’ sweet cherries with acceptable results and similar fruit quality. Difference in stem condition and bruising were more evident for irradiated ‘Rainier’ cherries than for MeBr treated ‘Rainier’ cherries, but these differences were small. Use of irradiation results in some firmness loss, for ‘Bing’ cherries when compared with MeBr, but irradiation treatment of cherries does not result in a loss of fruit and stem color, where the use of MeBr doses result in both fruit and stem color loss. Apricots (‘Perfection’ and ‘Rival’) and peaches (‘Regina’) are tolerant to irradiation at 300 gy with little quality loss. Loss of firmness, color changes and increased internal breakdown are evident in both apricots and peaches at irradiation dose above 600 gy. If irradiation dose above 600 gy is required to meet quarantine requirements unacceptable qualidy loss will occur in cherries, apricots and peaches.

    Notes: Controlled atmosphere (CA) storage for 45 or 90 days following harvest reduced quality losses for both ‘Gala’apples and ‘Bartlett’pears compared with fruit from regular atmosphere (RA) storage. Fruit stored in CA were firmer, had higher acidity and less color change than fruit from RA storage. Apples and pears stored together in CA maintained good quality and compared favorably with apples or pears stored separately. There was no difference in fruit quality between fruit stored at 1% O2 and 1% CO2 compared with fruit stored in 2% O2 and 3% CO2. Fruit harvested at a more advanced stage of maturity deteriorated more quickly in storage than earlier harvested fruit. A combination of 45 days in CA followed by 30 days RA resulted in apples that were superior in quality to apples stored for 75 days in RA alone.

    Notes: Packed pears (Pyrus communis‘d’‘Anjou’) were stored under four individual controlled atmosphere (CA) storage conditions (#1: CA of 1.5% O2 and 〈 1% CO2 at −1.5C; #2: CA of 1.5% O2 and 〈 1% CO2 at + 1.5C; #3: CA of 1.5% O2 and 3.0% CO2 at −1.5C; #4: CA of 1.5% O2 and 3.0% CO2 at + 1.5C). Loose pears in bins were stored under three CA storage conditions (#1: CA of 1.5% O2 and 〈1% CO2 at −1.5C; #2: CA of 1.5% O2 and 3.0% CO2 at −1.5C; #3: CA of 1.5% O2 and 3.0% CO2 at +1.5C). For packed pears, increased CO2 in the storage atmosphere resulted in retention of peel color, reduced firmness loss and enhanced subjective scores, particularly for finish and stem condition. Pears stored loose in bins, prior to packing in late January in an atmosphere containing 3.0% CO2 aided firmness retention, reduced scald and greatly enhanced subjective quality scores for appearance, finish and scuffing. Storing ‘Anjou’pears in a 3.0% CO2 atmosphere allows for storing pears loose in bin and packing in late January with little or no quality losses compared with using the standard 1.0% CO2 in the storage atmosphere.

    PREDICTION OF APPLE FIRMNESS FROM MASS LOSS AND SHRINKAGE (2004)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food quality 27 (2004), S. 0 
    Details
    ISSN: 1745-4557
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Prediction of firmness from mass loss and shrinkage was investigated in apples (Malus x domestica Borkh.) under regular atmosphere (RA) storage conditions. Apples (‘Delicious’ and ‘Fuji’) were repeatedly weighed to determine mass loss. Shrinkage was measured with a strain gauge sensor. ‘Delicious’ apples lost firmness (73 to 58 N) while ‘Fuji’ apples maintained firmness at 69 N over 57 days in storage. Apples lost mass at a constant rate with ‘Delicious’ losing mass slower (0.6 % per month) than ‘Fuji’ (1.1% per month). ‘Delicious’ apple shrank less (0.28 mm) than the ‘Fuji’ (0.70 mm) over 57 days. The relationship between firmness and mass loss, or shrinkage was dependent on apple cultivar. Firmness was significantly and linearly related to mass loss and to shrinkage in ‘Delicious’ apples. It is possible to predict firmness of ‘Delicious’ apples under RA storage conditions by tracking mass loss or shrinkage.

    Notes: The effect of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), infestation on the quality of sweet cherry, Prunus avium (L.) L., fruit was studied. Each cherry was infested with one first instar codling moth and held at 3.3C for 0 (control), 1, 2, 4, 7, 10, or 14 days. After cold storage, fruits were maintained at 25C and observed periodically for damage using a visual scale from 0 as no damage, to 9 as complete destruction. Two groups of ‘Bing’ cherries were examined, one from an organically grown orchard and the other from a commercial orchard with conventional chemical control. Uninfested fruits maintained quality for one month at 25C whereas infested fruits had a damage rating of 2 by the fifth day. Infested organic fruits deteriorated faster than the conventional cherries. Larvae were often not detected because of fruit deterioration and fungal contamination. Fruit quality deterioration due to codling moth infestation is an important component of the Systems Approach for quarantine security for cherries exported to Japan. Infested fruit would rapidly deteriorate as the result of decay and be culled at time of packing.
