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.

Estimation of plant hydraulics of grapevine in various «terroirs» in the Canton of Vaud (Switzerland)

The study of the physiological behaviour of the grapevine (cv. Chasselas), and of plant hydraulics in particular, was conducted on various « terroirs » in the Canton of Vaud (Switzerland) between 2001 and 2003 by Agroscope Changins-Wädenswil ACW, in collaboration with the firm I. Letessier (SIGALES) in Grenoble and the Federal Polytechnic School of Lausanne (EPFL). An evaluation of the vine plant hydraulics was made by means of physiological indicators (leaf and stem water potentials, transpiration and leaf stomatal conductance, carbon isotope discrimination and a model of transpirable soil water), in relation to estimations of the soil water reservoir and climatic factors.

Possible toxicological risk arising from contamination of grapes and derivatives by emerging mycotoxins: patulin

Following the acquired awareness of the presence of ochratoxin A in grape derivatives, actions were undertaken to contain this contamination, and attempts were made to evaluate the presence of any other molecule belonging to this class.

ASSESSING THE ROLE OF 27 KNOWN BITTER COMPOUNDS IN COMMERCIAL WHITE WINES COMBINING LC-MS QUANTIFICATION AND SENSORY ANALYSIS

The balance between the different flavours of a wine largely determines its perception and appreciation by the consumers. In white wines, sweetness and sourness are usually the two poles balancing the taste properties. The bitter flavour, on the other hand, is frequently associated with a loss of equilibrium and all white wines (dry and sweet, young and aged) are affected.
Several bitter compounds are already well-described in wines.

Impact of mannoproteins structural features on the colloid stability when facing different kinds of wine polyphenols

The aim was to study the impact of structural features in the polysaccharide moiety of mannoproteins on their interaction with polyphenols and the formation of colloidal aggregates.

Evaluation of Furmint clones in the Tokaj Wine Region

The ’Furmint’ is the most important grape variety in the Tokaj Wine Region, constituting around 65% of its vineyard area. Before the phylloxera disease many types were grown, but as selection started in the 20th century, its diversity dramatically narrowed. As a result, the cultivation of Furmint was based mainly on two heavy-cropping clones, T.85 and T.92 at the end of the ’80s. Aims of present clone research take into account that after solely quantity as target, quality emerged in the 1990’s and most recently, typicity appeared as more private estates began their own selection program.
