“…The interactive effect of illumination was studied by exposing the plastic containers with each of the atmospheres to light (300 µmol photons m -2 s -1 ) for 48 h, while the controls were maintained in the dark. It has been reported that modified atmospheres delay senescence, extend the life of different crops, and maintain phytochemicals [14]. This is in accordance with our results showing that modified atmospheres resulted in a substantial maintenance of chlorophyll content in the three species under both light and dark conditions (Figs.…”

The consumption of zeaxanthin (Z) through a vegetable-rich diet is recommended to reduce the progression of age-related macular degeneration. Due to Z's intrinsic dynamic character that results from its participation in the photoprotective xanthophyll cycle involving the carotenoids violaxanthin, antheraxanthin and zeaxanthin (VAZ), post-harvest handling practices and storage usually retain low amounts of this bioactive compound (compared to the rest of phytochemicals that are, in general, more stable). Thus, the aim of this work was to investigate in important consumed leafy vegetables the effects of different storage conditions on carotenoids (mainly Z) including i) packaging under three modified atmospheres (MAs), ii) light refrigerated supermarket storage and iii) dark refrigerated domestic storage. The results showed that an MA with low O 2 and high CO 2 enhanced the Z content under light. Moreover, both light and dark refrigerated storage showed dynamic and circadian pigment changes that enhanced the total VAZ pool. These results can contribute to generating practical recommendations for industries, supermarkets, and consumers when high Z content is a nutritional target.

“…Cucumbers were packed in bulk inside the large 100 cm × 50 cm LDPE bags of thickness 37.5 μm. For packaging design, the available permeability of film and the desired permeability of the film were calculated (Singh, 2014) 22 . Based on the difference between the available and desired permeability, the number of perforations to be made was decided.Unpackaged cucumbers in plastic crates (inner dimension: 570 × 365 × 143 mm) and packaged cucumbers were kept under three environmental conditions, namely, ambient (25 ± 8°C; 55 ± 14% RH), cool chambers (10°C and 90 ± 5% RH), and evaporative stores (19 ± 3°C; 82 ± 9% RH) to assess the impact of packaging and storage conditions on quality and shelf life of bulk packaged cucumbers.…”

Storage plays an important role in maintaining the post‐harvest shelf life of fresh fruits and vegetables. Cool storage of perishables is costly due to higher energy input. So, to reduce the operating cost and minimize the postharvest loss, a low‐cost on‐farm storage structure is required, especially in tropical developing nations. In this study, the effectiveness of different cool storage systems was validated by conducting shelf‐life studies on freshly harvested seedless cucumbers with (LDPE bags; 37.5‐μm thickness) and without packaging (open plastic crates) under ambient (25.0 ± 8°C; 55 ± 14% RH), cool storage (10.0°C; 90 ± 5% RH), and evaporative cool storage (ECS) systems (19 ± 3°C; 82.0 ± 9% RH). The shelf life and quality of cucumbers were determined based on weight loss, titratable acidity, total soluble solids, ascorbic acid, firmness, and total colour difference. Analysis of the data revealed that the effect of storage conditions and packaging on shelf life and quality was significant (p ≤ 0.05). It was found that the samples packaged in LDPE films had better firmness and lower weight loss as compared with unpackaged samples. Adoption of the evaporative cooling system helped in achieving temperatures of 8–10°C lower than the ambient depending on the environmental parameters. The relative humidity of the evaporative cooling system ranged from 75% to 90%, which is highly suited for the storage of fruits and vegetables. Although the shelf life of cucumbers was longer under cool storage (24 days), ECS could be used as an alternative for low‐cost on‐farm short‐term storage of fresh fruits and vegetables before marketing.

“…The PLW was analyzed by measuring the individual package at first and on day of perception (every 3rd day in case of samples stored at 10 °C; 2nd day in case of 30 °C temperature) using an electronic balance (FX 400 FCOSET, India) with a least count of 0.001 g. PLW was expressed as percentage of initial weight of packages (Rai, Gandhi, Kumar, Sharma, & Garg, ; Singh, Kumar, & Kaur, ).…”

This investigation elaborates the effect of storage conditions and packaging materials on the shelf life of cherry tomato stored under passive modified atmosphere packaging (PMAP) in heat‐sealed pouches. The fruits were encased with 25 µm thick continuous oriented pectin‐based bionanocomposite (PBNC), polypropylene, and low density poly ethylene packages and tested at 30 ± 2 °C relative humidity (RH = 61.2 ± 3%) and 10 ± 0.5 °C (RH = 90 ± 2%) storage conditions, while the fruits kept without packaging were taken as control. Advancement of storage in PBNC packages indicated significant decrement (p < .05) in the O2 concentration, firmness, and titratable acidity and significant increment (p < .05) in CO2 concentration, physiological loss in weight, total soluble solids, chroma, and total color difference. The lycopene concentration varied erratically as the senescence progressed. The type of packaging material used had no significant effect on the physiological, physico‐chemical, and biochemical properties of cherry tomato. PMAP coupled with low temperature (10 °C) prolonged the shelf life of cherry tomatoes till 24 days of storage. Practical applications The degradation of environment by the use of synthetic polymer based packaging materials has become a burgeoning problem. The need of biodegradable packaging materials with good mechanical and barrier properties is vital for checking sea and land pollution. The pectin‐based bionanocomposite film reinforced with magnesium hydroxide nanoparticles developed in this research will be helpful for the food packaging industry for sustainable packaging of fresh produce. Based on the experimental results, reinforcing of pectin film with magnesium hydroxide nanoparticles improved its physical, thermal, and barrier properties and helped in retention of bioactive compounds during storage of cherry tomato under modified atmosphere storage. These films competed well with low density polyethylene and polypropylene, which are largely used for packaging of fresh produce.
