Aloe-Based Edible Coating to Maintain Quality of Fresh-Cut Italian Pears (Pyrus communis L.) during Cold Storage

2021

Pear fruits are known for their antioxidant and nutritional characteristics. However, they are very susceptible to rapid decay. Edible coating (EC) represents a good strategy to maintain postharvest quality. The effects of two EC in slowing down the senescence processes in fresh-cut ‘Coscia’ pears were investigated: EC1 (A. vera gel, hydroxypropyl-methylcellulose and pomegranate seeds oil (PSO), EC2 (A. vera gel and hydroxypropyl-methylcellulose). Weight loss, firmness and colour decrease more slowly in both EC-treated than in untreated (CTR) slices; soluble solid content increases faster in CTR, indicating a faster ripening process. The specific investigation of undesired microorganisms di…

No. of bitstreams: 0 Previous issue date: 2013-02-07 Background: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. Th…

SICILY AS THEORETICAL MODEL TO STUDY THE POTENTIAL IMPACT OF GENETICALLY MODIFIED PLANTS IN A HOTSPOTS OF BIODIVERSITY

2015

In Europe, especially in Italy, different considerations are necessary when potential GMPs are to be grown. In particular high biodiversity areas such as Sicily should have a more detail plans of potential benefits and risks assuring the conservation of biodiversity and endemic species. Sicily is one of the most relevant biodiversity hotspots in the Mediterranean area, with a vascular flora of 3252 species and 321 endemic taxa. Considering the latest IUCN categories and criteria, 401 taxa (12.4% of Sicilian flora) are under threat (categories “CR”, “EN”, “VU”), and 220 more taxa (6.8%) are “Near Threatened”. Sicily is also known to have a rich butterfly and coleopteran fauna including endem…

Modifications over time of volatile compounds in coriander (Coriandrum sativum L.)

2007

Coriander (Coriandrum sativum L.) is an annual strongly-smelling herb belonging to the family Apiaceae, which is cultivated all over the world for its aromatic fruits (“seeds”) and, in many Asiatic and South American countries, for its green leaves. The aromatic features of leaves and fruits are sharply different, and the strong smell coming from leaves (many times referred to as a “bug” scent) is not always pleasant to many consumers from western countries. In our work, one Coriander small-seeded biotype has been grown in plastic covered greenhouses, and at given time intervals samples of leaves, flowers and fruits have been analyzed by means of HS-SPME and GC-MS to study the evolution ove…

Functional food characteristics in organic food products—the perspectives of Italian consumers on organic eggs enriched with omega-3 polyunsaturated …

2022

Abstract Innovation in organic food products plays an important role in further developing its competitiveness in the market and meeting the emerging consumers’ needs. However, few studies have analysed consumers’ points of view of innovations on organic food, limited to the change in the natural food composition or the enrichment of the nutritional contents of the product. This study, using experimental auctions, aims to overcome this gap by enriching the knowledge on organic consumers’ preference for organic food with functional characteristics. Specifically, this study analyses the willingness to pay (WTP) of 110 Italian consumers for organic eggs enriched with omega-3 polyunsaturated fa…

The conservation of the Italian Crop Wild Relatives in the RIBES seed-banks: first data to establish national inventories and conservation priorities.

2016

The authors present the updated results of such census in the Italian Seed Bank Network for native species conservation (RIBES) with an analysis of the contribution to the conservation of the Italian FAO priority CWR. Finally, a national priority list for conservation of CWRs was drawn up and proposed here.

The conservation of the endemic Crop Wild Relatives in the RIBES seed-banks: towards a national priority list for the Italian CWRs

2016

Data of 620 crop wild relatives of species of food and fodder interest listed in the Annex I of the FAO Treaty (FAO, 2001) were collected within the census carried out by ISPRA, the Italian National Institute for Environmental Protection and Research, in 2014-2015 in order to quantify the extent of CWR representation in the Italian ex situ collections. According to such census, the RIBES network preserve 37% of the Italian CWRs listed in the FAO Treaty: in 14 out of 16 seed-banks are preserved 6,029 accessions of 229 CWR taxa, belonging to 11 families and 57 genera.

Microwave effects on germination and growth of radish (Raphanus sativus L.) seedlings

2002

Germination of radish seeds was delayed and reduced by low-power microwave exposure at 10.5 and 12.5 GHz. Irradiation decreased also hypocotyl growth rate. These effects were increased by rising of the microwave power and by the vertically polarised electromagnetic field. When the irradiation was suspended the seedling growth recovered.
