Plum and Fresh Prune
2015Co-Authors: Carlos H. Crisosto, Adel A. KaderAbstract:Scientific Name and Introduction: Plums (Prunus salicina) are mainly marketed for fresh consumption and not for drying. They are also used for canning, freezing, and jam and jelly making. The Japanese plum is native to China, but was domesticated in Japan 400 years ago. It was first brought to California from Japan in 1870 by John Kelsey. In 1885, Luther Burbank imported about 12 seeds from Japan, and used them to breed many cultivars. The plum industry has increased throughout California (mainly in the centra

postharvest handling of plums Prunus salicina lindl at 10 c to save energy and preserve fruit quality using an innovative application system of 1 mcp
Postharvest Biology and Technology, 2013Co-Authors: Gayle M Crisosto, Ioannis S Minas, Deirdre M Holcroft, Miltiadis Vasilakakis, Carlos H. CrisostoAbstract:Abstract 1-Methylcyclopropene (1-MCP) inhibits softening in plums, making it a candidate for a postharvest strategy of storing fruit at higher than normal storage temperatures to avoid chilling injury (CI) while providing energy and cost savings. This hypothesis was tested by exposing different Japanese plum ( Prunus salicina Lindel.) cultivars to 0.5 μL L −1 1-MCP at 0 °C for 24 h. Following 1-MCP treatment, fruit were stored at 0 or 10 °C for 10, 20, or 30 d, respectively. A new application technology was tested by applying 1-MCP during forced-air cooling (FAC), reducing the application duration from 24 to 6 h without affecting treatment performance. This new 1-MCP application system is compatible with current postharvest handling, rendering it easily adopted by the tree fruit industry. 1-MCP had no detrimental effect on consumer acceptance of low-acid plums ripened properly prior to consumption, but it reduced the acceptance of high acidity plums. Thus, 1-MCP use on plums should avoid cultivars with high acidity and/or plums picked early when fruit have titratable acidity of 0.9% or more. 1-MCP–FAC treatment followed by storage at 10 °C is a promising new methodology to avoid chilling temperatures and provide considerable energy savings without reducing postharvest life and consumer quality of low-acid plums. Our results encourage testing this new technology at commercial scale to accurately quantify energy savings and consumer reactions for specific operations and markets.

evaluation of the effect of different modified atmosphere packaging box liners on the quality and shelf life of friar plums
Horttechnology, 2008Co-Authors: Celia M Cantin, Carlos H. Crisosto, K R DayAbstract:ADDITIONAL INDEX WORDS. MAP, storage, internal breakdown, gel breakdown, firmness, translucency, Prunus salicina SUMMARY. The influence of modified atmosphere packaging (MAP) on quality attributes and shelf life performance of ‘Friar’ plums (Prunus salicina) was studied. Plums were stored at 0 � C and 85% relative humidity for a 60-day period in five different box liners (LifeSpan L316, FF-602, FF-504, 2.0% vented area perforated, and Hefty liner) and untreated (control). Flesh firmness, soluble solids concentration, titratable acidity, and pH were unaffected by the box liners. Fruit skin color changes were repressed on plums packed in box liners that modified gas levels and weight loss was reduced by the use of any of the box liners. Plums packed without box liners (bulk-packed) had 6% weight loss. High carbon dioxide (CO2) and low oxygen (O2) levels were measured in boxes with MAP box liners (LifeSpan L316, FF-602, and FF-504). Percentage of healthy fruit was unaffected by any of the treatments during the ripening period (shelf life) after 45 days of cold storage. However, after 60 days of cold storage, fruit from the MAP box liners with higher CO2 and lower O2 levels had a higher incidence of chilling injury (CI) symptoms, evident as flesh translucency, gel breakdown, and ‘‘off flavor’’ than fruit from the other treatments. Overall, results indicate that the use of MAP box liners is recommended to improve market life of ‘Friar’ plums up to 45 days cold storage. However, the use of box liners without gas control capability may lead to CI symptoms in fruit cold-stored for longer periods.

novel 1 methylcyclopropene immersion formulation extends shelf life of advanced maturity joanna red plums Prunus salicina lindell
Postharvest Biology and Technology, 2008Co-Authors: George A Manganaris, Carlos H. Crisosto, V Bremer, D HolcroftAbstract:Abstract A postharvest application, by immersion, of a new 1-methylcyclopropene (1-MCP) formulation delayed ripening changes and extended the shelf life period of plum fruit (Prunus salicina Lindell cv. Joanna Red) harvested at an advanced maturity stage when ripened immediately after harvest or after cold storage. Fruit were either immersed in a water solution (control) or in an aqueous solution of a formulation containing 10, 100, 1000 and 10,000 ng kg−1 of 1-MCP. The fruit were allowed to ripen at 23 °C after 5-m immersion or after immersion and subsequent cold storage (5 °C, RH 90%) for 10 d, prior to being evaluated for quality attributes. 1-MCP immersion treatments reduced firmness loss, skin color changes, fruit weight loss and respiration rate. Furthermore, a pronounced suppression of ethylene production in fruit treated with 1000 and 10,000 ng kg−1 1-MCP was detected. All fruit ripened normally and did not show any chilling injury (CI) symptoms when ripe fruit were evaluated after cold storage. Overall, 1-MCP concentration of 1000 ng kg−1 was the most effective in controlling fruit ripening changes and extending the shelf life of this advanced maturity (tree ripened), low CI susceptible plum. This is the first study, to the best of our knowledge, reporting the successful application of 1-MCP by immersion on the postharvest performance of fleshy fruit.

effect of dips in a 1 methylcyclopropene generating solution on harrow sun plums stored under different temperature regimes
Journal of Agricultural and Food Chemistry, 2007Co-Authors: George A Manganaris, Carlos H. Crisosto, Ariel Roberto Vicente, John M LabavitchAbstract:The effect of postharvest dips in a 1-methylcyclopropene-generating solution of the formulation AFxRD038 (Rohm & Haas) on plum fruit (Prunus salicina Lindell cv. ‘Harrow Sun’) quality and ripening during storage was determined. Fruit weight loss, tissue firmness, soluble solids content (SSC), titratable acidity (TA), ethylene production, respiration, and the activities of the cell wall modifying enzymes polygalacturonase (PG), 1,4-‚-D-glucanase/glucosidase (EGase), ‚-galactosidase (‚-gal), and pectin methylesterase (PME) were measured. Fruit reddening, anthocyanin content, and phenylalanine ammonia-lyase (PAL) activity were also analyzed. The 1-MCP-treated fruit showed reduced ethylene production and respiration rate and delayed softening, which was associated with the reduction in the activity of PG, EGase, and ‚-gal. The immersion in 1-MCP-generating solutions also decreased weight and acidity loss without modifying the fruit SSC. The immersion treatment was particularly effective in the fruit stored at 5 °C, keeping higher overall quality, maintaining lower levels of anthocyanins and PAL activity, and preventing flesh reddening. The present data show that beneficial effects in delaying plum fruit ripening and controlling chilling injury can be obtained by dipping the fruits in a solution of this novel 1-MCP-generating formulation.

Japanese plums (Prunus salicina Lindl.)and phytochemicals – breeding, horticultural practice, postharvest storage, processing and bioactivity
'Wiley', 2014Co-Authors: Fanning, Kent J., Topp Bruce, Russell Dougal, Stanley Roger, Netzel MichaelAbstract:Previous reviews of plum phytochemical content and health benefits have concentrated on the European plum, Prunus domestica L. However, the potential bioactivity of red- and dark red-fleshed Japanese plums, Prunus salicina Lindl., so-called blood plums, appears to warrant a significant increase in exposure, as indicated in a recent review of the whole Prunus genus. Furthermore, Japanese plums are the predominant plum produced on an international basis. In this review the nutrient and phytochemical content, breeding, horticultural practice, postharvest treatment and processing as well as bioactivity (emphasising in vivo studies) of Japanese plum are considered, with a focus on the anthocyanin content that distinguishes the blood plums

combined effects of aqueous chlorine dioxide and ultrasonic treatments on postharvest storage quality of plum fruit Prunus salicina l
Postharvest Biology and Technology, 2011Co-Authors: Zhao ChenAbstract:Abstract The individual and combined effects of aqueous chlorine dioxide (40 mg L −1 ClO 2 for 10 min) and ultrasonic (100 W ultrasound for 10 min) treatments on postharvest storage quality of plum fruit ( Prunus salicina L.) were investigated. Two combination modes of these two treatments, treatment with ClO 2 solution accompanied by simultaneous ultrasonic waves (one-step mode) and applying them sequentially (two-step mode) were adopted. The effect of combined treatments on maintaining contents of total flavonoids, ascorbic acid, reducing sugars, and titratable acids were similar but were more beneficial than the individual treatments and the untreated control. The one-step mode was more effective in reducing the initial microflora and retaining sensory qualities of plum fruit than the two-step mode, and fruit shelf-life could be extended to 60 d compared to 35 d for the control. Moreover, there were no detectable chemical residues in the treated samples with the one-step mode. These results demonstrated that the combined treatments of ClO 2 and ultrasound could be a promising approach to maintain postharvest storage quality of plum fruit without significant risks to consumers.
