“…The high CO 2 in the internal atmosphere of this package had a fungistatic effect, slowing the marked increase in decay observed in the other packages at a similar storage at 18ЊC. Researchers have reported incidences of fungal spoilage in berries if they were wrapped with plastic films generating high CO 2 atmospheres during storage at low temperatures (Barkay-Golan et al, 1983;Browne et al, 1984;Picón et al, 1993). Aharoni and Barkai-Golan (1987) reported lower fruit decay in 'Aliso' fruits packed in PVC after 10 days storage at 2ЊC plus two days storage at 20ЊC.…”

The quality of strawberries (Fragaria ∞ ananassa Duch. cvs.Oso Grande and Camarosa) non wrapped or packed in cellulose, perforated polypropylene, nonperforated polypropylene (automatically), and polyvinylchloride (manually) during storage at 18ЊC was compared. Nonperforated polypropylene packages of fruit had the highest CO 2 and the lowest O 2 content, and the most desirable quality parameters. However, this type of package had undesirable appearance due to water condensation. Cellulosic films maintained a well balanced internal atmosphere, but were wrinkled. Perforated polypropylene and polyvinylchloride packages exhibited the best appearance, but fruits packed in perforated polypropylene films rapidly deteriorated. Unwrapped fruits had the least desirable quality in both varieties.

“…39,40 The primary cause of off-flavours appears to be related to the accumulation of acetaldehyde, ethyl acetate and ethanol caused by anaerobic respiration. 4 According to Ke et al,3 off-flavour development was correlated strongly with ethanol content and to a lesser extent with ethyl acetate and acetaldehyde accumulation.…”

Equilibrium modified atmosphere packaging of wild strawberries

Wild strawberries (Fragaria vesca L.) are high-added-value fruits but their marketing is complex owing to their short postharvest life. In this work, equilibrium modified atmosphere packaging (EMAP) technology was used to maintain their quality and consequently to extend their life. Fresh strawberries were packaged with two continuous and three microperforated films (with different gas permeabilities) with the purpose of obtaining equilibrium atmospheres of diverse compositions. Weight loss, pH and acidity, solid content, colour, firmness, fungal decay and development of off-flavours were selected to monitor fruit quality during 6 days at 10• C. Among the five packages tested, microperforated films with one and three perforations provided adequate CO 2 and O 2 equilibrium concentrations in view of the evolution of chemical and physical quality parameters. These results were confirmed by sensory analysis.  2007 Society of Chemical Industry Keywords: wild strawberry fruit; MAP; microperforated films; quality parameters INTRODUCTIONThe natural appearance, colour and nutritional value of wild strawberries (Fragaria vesca L.) are characteristics which make these fruits highly appreciated by consumers. However, the postharvest preservation of wild strawberries is very complex owing to a very fast metabolism and the presence of microbial contamination which cannot be reduced by external washing, as in other fresh products, owing to an extremely sensitive surface. At room temperature the shelf life of wild berries is below 48 h. Among other strategies to reduce postharvest losses, combinations of low-temperature, high-humidity storage and the use of carbon dioxide have proved to be effective.1 Several reports have associated their effect on fruits (including cultivated berries) with reductions in dehydration, respiration and ethylene production rates.

Unripe green Conference pears with initial firmness values of 46-55N were sealed in modified atmosphere (MA) low density polyethylene (LDPE, 30 p) pillow packs and in perforated control packs on three dates during [1985][1986]. Changes in pack atmosphere composition, skin chlorophyll content, flesh firmness and sensory quality were monitored during 14-20 days simulated shelf-life at 20°C. In MA packs, equilibrated atmospheres containing 5-9% C02 and <5% 0 2 developed within c. 3 days. Chlorophyll degradation was completely inhibited by MA and resumed when packs were perforated, but MA only partially retarded the rate of flesh softening. Variations in the rate of ripening changes in duplicate MA packs could not be explained simply by differences in pack atmospheres. Furthermore, pears retarded by MA packaging failed to develop the normal sweet, aromatic flavour and succulent, juicy texture of 'eating-ripe' fruit, even when the packs were perforated after 4 days.The differences in the responses of pears and apples to MA packaging, and the limitations of using this technique for the commercial marketing of English pears are discussed.
