Physiochemical Changes of European Pear cv. Conference and Asian Pear cv. Yali during Cold Storage

نویسندگان

چکیده

This study evaluated the physiochemical changes of one commercial European pear variety ‘Conference’ and Asian ‘Yali’ during 60 days storage at 1 °C. Content organic acids, ethylene formation CO2 were determined using HPLC/UV-VIS GC/FID TCD detectors, respectively. presents an evaluation influence above-mentioned factors long-term on quality parameters, including antioxidant capacity important cultivar. There was a significant effect temperature respiration rate in both varieties. Development intensity had similar course pears. The high values production beginning for (14.08 mg·kg−1·h−1) (23.37 followed by sharp decline 80% 83% later stages °C, Ethylene fruit increased with time highest after cold storage, especially (7.14 µL·kg−1·h−1). results show relation between ripening-related parameters. showed negligible soluble solids content flesh firmness ranging from 0.35 to 0.60 MPa. most represented sugar enzymatically fructose malic acid dominant fruit. Antioxidant activity FRAP DPPH methods did not change significantly storage.

Influence of 1-methylcyclopropene on ripening, storage life, and volatile production by d'Anjou cv. pear fruit.

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...

Changes in Isoperoxidases during Cold Treatment of Dormant Pear Embryo.

The number of isoperoxidases and the intensity of certain isozymes increased with increasing periods of stratification of pear (Pyrus communis cv. Bartlett) embryos. The presence of GA(3) or kinetin during stratification enhanced the activity of certain isoperoxidases, and these enhancements were blocked in the presence of ABA which by itself had an inhibitory effect. Enhancement in isoperoxida...

Kinetic Studies With Crude wild pear Lipoxygenase at during ripening and after storage

Crude wild pear lipoxygenase (LOX) from ripe Kurdistan wild pears was used in this study. Extracted crude LOX was assayed spectrophotometrically for raw, ripe wild pear lipoxygenase and after 7-day storage. The effects of different buffers and pHs, substrate preparations, temperature, inhibitors and metal ions on LOX activity were evaluated at three conditions. The enzyme was most active with H...

Ascorbic acid concentration in Cv. conference pears during fruit development and postharvest storage.

L-ascorbic acid (L-AA) concentration changes during the development of cv. Conference pears and the influence of postharvest handlings (gas condition, cooling rate, cooling duration) on L-AA breakdown were studied. L-AA concentration fluctuates in young fruits, remains stable during fruit maturation, and starts to decline 1 week before commercial harvest. The most rapid decrease in L-AA concent...

Effect of nitric oxide on biochemical and antioxidant properties of pomegranate fruit cv. Shishe-kab during cold storage

Pomegranate is a subtropical fruit that is widely consumed as fresh fruit and juice, however, its postharvest life is limited mainly due to storage disorders. The aim of this study was to determine the effect of nitric oxide (NO) on antioxidant activity and quality attributes of pomegranate fruit. The fruits were dipped for two minutes into different NO concentrations (0, 30, 100, 300 or 1000 µ...
