Influence of modified atmosphere packaging on shelf-life of green chillies (Capsicum annuum L.)

BACKGROUND This study used the isobaric tags for relative and absolute quantitation (iTRAQ) technique to determine the effects of active modified atmosphere packaging (MAP) on the modulation of lettuce (Lactuca sativa L. Grand Rapid) colour and senescence. Lettuces, treated or not treated (control) with MAP, were placed in a refrigerator (4 °C, 90–95% relative humidity) for analysis at 3‐day intervals until the ninth day. RESULTS MAP treatment could suppress weight loss, loss of green colour and brittleness, and browning of lettuce; at the same time, MAP preserved the green colour of lettuce by inhibiting chlorophyll degradation and chloroplast disruption, and delayed lettuce senescence by inhibiting malondialdehyde (MDA) generation and increasing antioxidant enzyme activity. In total, 285 differentially abundant proteins (144 upregulated proteins and 141 downregulated proteins) were identified in MAP‐treated and non‐treated lettuce. Further analysis revealed that MAP regulated the expression of proteins involved in photosynthesis (e.g. pheophorbide a oxygenase, PaO; porphobilinogen deaminase, PBGD), and thus preserved lettuce colour. The iTRAQ analysis also showed that MAP regulated the expression of antioxidant enzymes and reduced the accumulation of reactive oxygen species, and thus delayed lettuce senescence. CONCLUSION MAP can maintain vegetable quality by inhibiting chlorophyll degradation, delaying vegetable senescence. © 2018 Society of Chemical Industry

Three cultivars of green pepper with unique fruit shapes, 'Kkwariput', 'Gilsang', and 'Cheongyang', were investigated for changes in physiology and functional compounds during storage to optimize postharvest management. The results showed that the respiration and ethylene production rates of 'Gilsang' were lower than those of 'Kkwariput' and 'Cheongyang', having the lowest weight loss during storage at both 4℃ and 20℃. The 'Cheongyang' pepper exhibited the highest firmness among the three cultivars, and it remained high until the end of storage. The soluble solids content and the titratable acidity were significantly higher in 'Cheongyang' than in 'Gilsang' and 'Kkwariput'. With regards to fruit color, in all three cultivars the L* values decreased while the a* values increased with storage time. Based on the appearance index, 'Cheongyang' had a longer shelf life at 20℃ than 'Gilsang' or 'Kkwariput'. However, 'Gilsang' showed the lowest seed browning rate at 5 day at 20℃ among the three cultivars after 14 day of cold storage at 4℃. The results of functional compounds analysis showed that capsaicin content increased with storage time, with the highest content found in 'Cheongyang'. Antioxidant capacity, as determined by ABTS and DPPH assays, increased with storage time, and 'Cheongyang' showed higher antioxidant retention capacity than 'Gilsang' and 'Kkwariput'. The highest vitamin C content was also found in 'Cheongyang'. Based on the overall superior results of the 'Cheongyang' cultivar, this study suggests a close correlation between the retention capacity of functional compounds and the shelf life in green peppers.

“…Modified atmosphere packaging (MAP) is well known for storing fresh fruit and vegetables because it preserves the high quality of produce by restricting the transmission of respiratory gases stored in semipermeable polymeric films . Modified atmosphere packaging with low O 2 and high CO 2 is helpful for maintaining the quality of fresh produce by decreasing the physiological activities, preventing microbial growth, and inhibiting oxidation .…”

Modified atmosphere packaging (MAP) storage has become a useful technique for extending the shelf life of fruit and vegetables. However, the success of MAP depends on many factors, including types of fresh products, storage conditions, and the characteristics of the packaging films. To achieve the optimal gas composition in the package headspace and improve the postharvest quality of fresh produce, the packaging film with appropriate barrier properties needs to be selected. This study aimed to predict the film thickness by applying produce respiration rate and package film permeability data measured in given product weight and storage conditions. An available film (eg, 25‐μm‐thick low‐density polyethylene) was used to pack fresh produce, and the respiration rate of fresh produce and in‐package O2 and CO2 concentrations at steady state were measured. Permeability of the film was calculated based on mass balance, and the thickness of the film could be predicted if the recommended target O2 and CO2 concentration was obtained from the literature. To validate the predicted thickness value, an experiment was conducted by packaging fresh table grapes in bags of the predicted thickness. The effect of packaging with different film thicknesses on the quality of the fruit was determined. The results showed good agreement between the predicted and the experimental in‐bag O2 and CO2 concentrations, and the MAP with predicted thickness (90 μm) film was more effective in maintaining postharvest quality of grapes during low‐temperature storage than the thinner films (30 and 60 μm) and the control.
