Effects of Rapid Refrigeration and Modified Atmosphere Packaging on Litchi (Litchi chinensis Sonn.) Fruit Quality Traits

2017

Litchi (Litchi chinensis Sonn.) is a tropical fruit characterized by a rapid pericarp browning and dehydration during postharvest, resulting in an accelerated shelf life and in a loss of consumer appreciation and consequently of its market value. The aim of our study was to assess litchi fruit chemical-physical and sensory quality changes during postharvest and shelf life using rapid refrigeration (RR) and active modified atmosphere packaging (MAP). Litchi fruits were picked at commercial harvest and were divided in 4 groups: not treated fruit (CTR); rapid refrigerated fruit (RRF); modified atmosphere packed fruit (MAP); hydrogen peroxide treated and modified atmosphere packed fruit (MAP+).…

A New Calibration Equation for Diviner2000 Capacitance Probe Accounting for Soil Shrinkage Characteristic Curve and Estimation of Parameters on the B…

2014

Real-time measurements of soil water status are quite often used for irrigation scheduling and particularly in precision irrigation, in order to identify the exact timing and amount to supply to crops according to their water requirements. Diviner2000 capacitance probes, measuring the apparent soil dielectric permittivity, have been extensively used in the last decade. Several studies have shown that, for different soils, there is a relationship between the volumetric soil water content (SWC) and the scaled frequency (SF) measured by the sensor. However, for swelling/shrinking clay soils, for which bulk density changes with soil water content, there is a lack of knowledge on how these varia…

Indirect estimation of calibration equation parameters for Sentek Diviner 2000 capacitance probe by means of soil physical properties

2014

Measurements of soil water content (SWC) are often used for irrigation scheduling. Accurate monitoring of SWC is necessary, for example, to identify the exact irrigation timing and the amount of water volume to supply according to the crop requirement. The use of capacitance probes, measuring the apparent soil dielectric permittivity, indirectly related to soil water status, have been increasing during the last decade, as proved by the numerous researches carried out to determine, for different soil types, site-specific calibration relationships between SWC and the scaled frequency (SF) measured by the sensor. However, for swelling/shrinking clay soils, there is a lack of knowledge on how t…

Color and sensory changes in fresh cut pear during storage comparing ‘Coscia’ and ‘Butirra’, cultivated in southern Italy

2023

Pear (Pyrus communis L.) cultivars ‘Coscia’ and ‘Butirra’, cultivated in southern Italy are characterized very excellent by aroma and texture. Visual appearance is the primary descriptor that determines the acceptance of fresh-cut pears. Softening is another important quality parameter which considerably influences the acceptance of fresh-cut pears. The aim of this work was to study the effect of genotype on shelf life and quality of fresh-cut pear fruit harvested at commercial maturity stage. After cutting, pear fruit samples were stored under passive atmosphere at 5±1°C for 3, 5, 7 and 12 days. Fruit color (L*, a*, b*, ΔE), consistence, solid soluble, titratable acidity, CO2 and O2 packag…

Growth and yields of 'Arbequina' high-density planting systems in three different olive growing areas in Italy

2014

The sustainability of the traditional olive-growing sector in EU countries characterised by high production costs and a low selling price for the oil was mainly determined by EU subsidies available for the sector. With the opening of the free trade area by the Barcellona Declaration of 1995 and a cut in EU subsidies in 2014, crucial changes in the sector are now needed. In order to increase the competitiveness of EU olive production, attention should be given to new high-yielding and mechanized cultivation systems. In the 1990s, Spain introduced new high-density planting systems (1,200-2,000 trees/ha) using three low-vigour and early-fruiting cultivars ( Arbequina , Arbosana and Koroneiki )…

Evaluation of quality attributes and consumer preference of fresh or imported mangoes in Italy

2018

Mango is a climacteric fruit with a very short shelf-life due to its rapid ripeness after harvest. Generally, fruit from tropical countries and directed to longer transportation (EU markets), are in general harvested firm, before complete ripening (mature-green stage). This harvest practice usefully for mango fruit storability and transportability, generally causes fruits quality and taste decrease. The present study was conducted to evaluate quality attributes and consumer preference of fresh or imported mangoes in Italy. Mango fruit imported from abroad (cv Keitt, Kent and Osteen) were collected from 2 different large-scale organized distribution markets (LD). Mango fruits (cv Keitt, Kent…

Effetti della tecnologia Modified Atmosphere Packaging a base di argon sulla qualità degli arilli di melograno (Punica granatum L. cv. Wonderful)

2021

La coltivazione del melograno è aumentata globalmente nell’ultimo decennio grazie ai rinomati benefici del frutto per la salute. Il consumo del melograno come frutto fresco, però, incontra delle resistenze da parte dei consumatori a causa della scomodità di estrazione degli arilli dal frutto e della presenza di metaboliti fenolici che possono macchiare le mani. Oggi si sta diffondendo sempre più il consumo di arilli pronti al consumo, pratici e veloci in confezionamento protettivo per cui occorre mantenere inalterate le caratteristiche qualitative del frutto fresco. Il confezionamento in atmosfera modificata (MAP) è stato utilizzato negli ultimi anni per mantenere la qualità della frutta di…
