Effect of different packaging materials on table grape quality preservation during cold storage

Abstract

During cold storage, grapes undergo changes that affect their visual, mechanical, and organoleptic properties, potentially impacting quality and negatively influencing consumer acceptance. Key parameters include uniform color, crunchiness, and flesh consistency. We evaluated the influence of two distinct packaging methods on the chromatic characteristics, hardness, and pedicel detachment resistance of fourteen new seedless white and red grape varieties during cold storage. These factors are crucial for maintaining the quality of the product and extending its shelf-life. The novel grape varieties were obtained through a breeding program at CREA-VE of Turi, Southern Italy. The harvested bunches were divided into carton boxes and plastic clamshells without SO2 generating pads. They were then stored at 2°C with 95% relative humidity. The CIELab coordinates, hardness value, and pedicel detachment force of the berries were measured at harvest and after 14 and 21 days of cold storage. The differences between the groups were assessed using an ANOVA, followed by Fisher’s LSD post-hoc test. In the case of carton packaging, cold storage did not affect the hardness of seven varieties, the chromatic coordinates of three varieties, and the pedicel detachment force of ten varieties. However, for plastic-packed varieties, two groups of six different varieties each showed stable values of hardness and detachment, while four varieties maintained the colour parameters. When it comes to Barese cv. packed in both carton boxes and plastic clamshells, there was no significant difference in any of the parameters evaluated, indicating a good cold storage ability.

Copper reduction strategy for sangiovese in organic viticulture

Organic viticulture requires copper based treatments for bunch protection even though an intensive employment is no longer admitted because of its low leaching and phytotoxicity in the soil. UE Reg. 1981/2018 set copper employment to 4 kg/ha for year or 28 during 7 years with an absolute level allowed of 6 Kg/ha although those limits were decreased frequently.

Preplant fumigation only temporarily reduces Northern root-knot nematode

Management of plant-parasitic nematodes is typically focused on preplant fumigation, especially in a vineyard replant scenario. While the data are clear that this practice reduces nematodes immediately after application, which is useful in annually-cropped systems, does it have staying power in perennial cropping systems? The northern root-knot nematode Meloidogyne hapla reduces the overall lifespan and productivity of vineyards, but it does so over a long time period (slow, chronic decline). In two different commercial own-rooted V. vinifera vineyards, both undergoing vineyard replanting, we explored whether preplant fumigation reduced M. hapla densities in soils immediately after application. At one of these locations, we have explored the long-term effect of fumigation by monitoring the site for seven years post fumigation.

Environmental and yearly influences on four Sicilian grape clones under climate change challenges

By the end of this century, up to 90% of traditional viticulture regions in the Mediterranean, including Sicily, are projected to face extinction due to escalating climate challenges such as severe droughts, heatwaves, and unseasonal rains.

Regionality in Australian Pinot Noir wines: A study using NMR and ICP-MS with commercial wines

Aim: Wine quality and character are defined in part by the terroir in which the grapes are grown. Metabolomic techniques, such as nuclear magnetic resonance (NMR) spectroscopy and inductively coupled plasma mass spectrometry (ICP-MS), are used to characterise wines and to detect wine fraud in other countries but have not been extensively trialled in Australia. This study aimed to investigate the use of ICP-MS and NMR to characterise a selection of Pinot noir wines.
