The potential of pineapple (Ananas comosus L.) as export commodity both for fresh consumption and for the fruit processing industry has continue to increase. However, fresh pineapple can only be stored for 2-3 days at room temperature after ripening. On the other hand, the export process requires at least 35 days for delivering and retailing period. Long duration and distance is needed for fruit transportation thus it is required a special storage treatment to extend the shelf life. Modified atmosphere packaging has been proven to modify the air around the product to extend shelf life, especially fresh fruit and vegetable. In this study, modified atmosphere packaging technique was applied to whole pineapple using LDPE plastic. The amount of O2 and CO2 at various composition was tested and then the samples were storage at temperature of 7°C, 10°C and 28°C room temperature. The quality of the fruit was determined by the parameter of weight loss (%), hardness (mm/5s) and color. Control, pine apple was package without MAP, showed a significant quality deprived. Based on research, the best atmospheric composition to extend the shelf life of fresh pineapple was 1-3 % O2 and 5-10 % CO2 at 10 °C storage temperature. This condition gave a slow decrease in quality such as the weight loss was about 0.0296 %, the hardness value was 0.0393 mm/second and the organoleptic test was still under consumer’s acceptance.

“…The green pigment is one of the main factors affecting the quality of broccoli ascribable to chlorophyll degradation, which is the first apparent sign of senescence, leads to customer rejection, and lowers the market price [47]. The chlorophyll contents of broccoli in the different treatments showed an overall downward trend according to Table 4 and Figure 4a, which was confirmed by Torales et al [48], where the results involved degradation of chlorophyll caused by enzymatic reactions that occur mainly within the chloroplasts and vacuoles, which includes the interrelated expression of genes coding proteins involved in chlorophyll degradation [49]. After 5 days of storage, vacuum and ice-cooled samples significantly retarded the degradation of chlorophyll in broccoli [50].…”

Poor and inconsistent quality is a major barrier to increasing produce consumption, and the lack of shelf-life after purchase is the quality issue at retail displays of produce. This research aimed to investigate and identify cooling techniques, namely vacuum cooling and package icing used in supply chains, and any resulting extension of broccoli shelf-life, maintenance of physicochemical quality, and delay in microbial growth at retail stores. Broccoli (Brassica oleracea var. italica cv. Montop) sustainably grown in the highlands of northern Thailand, Chiang Mai Province, under the Royal Project Foundation was experimented on vacuum cooling and package icing were selected to precool broccoli to 4 ± 1 °C. The effects of vacuum cooling using a final pressure of 0.6 kPa for 30 min and package icing using liner Styrofoam boxes (the best ratio of broccoli to crushed ice was 1:1 w/w) on physicochemical qualities, microbial growth, and shelf-life in simulated refrigerated retail displays were examined. The results illustrated that the shelf-life and quality of broccoli could be extended using both vacuum cooling and package icing. Both precooling techniques inhibited the yellowing of florets, provided high sensory scores, delayed microbial growth, and could be able to extend the shelf-life of broccoli. However, package icing offered greater potential for maintaining quality, especially retaining bioactive compounds, and extending shelf-life, thereby increasing the produce market window from 5 to 12 days at 8 ± 1 °C with 85% RH. Therefore, package icing was recommended in the supply chain for fresh broccoli cv. Montop grown in northern Thailand.

“…1,2 During the storage and retail distribution of garlic scapes, CO 2 can easily accumulate because of the environment of high CO 2 in the modified atmosphere packaging and from self-respiration. [3][4][5] Excessive CO 2 causes high levels of damage, leading to anaerobic fermentation reactions and accelerating deterioration. 6 Studies have reported that when the concentration of CO 2 is higher than 20%, all types of fruits and vegetables will be damaged.…”

A pH‐sensitive indicator film based on CO2 change was prepared by mixing a water‐soluble indicator (bromocresol green and chlorophenol red sodium) with a film‐forming carrier (methyl cellulose (MC), polyvinyl alcohol (PVA) and glycerin). The innovation is not only to analyse the response characteristics of the colorimetric indicator to CO2, but also to optimise the preparation parameters of the film. The response experiment showed that CO2 dissolved rapidly in water and the pH value remained unchanged after reaching equilibrium, with a one‐to‐one relationship between pH and CO2 concentration. As the CO2 concentration rose from 18% to 20%, the colour of the indicator film changed from blue–purple to yellow–green in a different colour space, allowing the change to be easily distinguished by the naked eye. The optimum parameters (13 g‧L−1 MC, 5 g‧L−1 PVA, 10 g‧L−1 glycerin, 15 ml‧L−1 indicator and a casting amount of 0.2 ml‧cm−2) for preparing the intelligent film were optimised based on puncture strength (PS), water vapour permeability (WVP), water solubility (WS), casting time (CT) and colour performance. Evaluating this application using garlic scapes stored at 15°C revealed that the total colour difference was 34.23 as the CO2 concentration increased from 18.7% to 20.4%, and the colour of the indicator film changed from blue–purple to yellow–green. Therefore, the intelligent packaging film was able to effectively provide a warning when garlic scapes were exposed to damage from a short‐term high CO2 level.
