Quality determinants of avocado fruit consumption in italy. Implications for small farms

2018

In recent years there has been an increasing consumer interest towards tropical fruits due to the desire of consumers for healthy eating while experiencing new and exotic flavours. Within this consumer trend, avocado fruit presents great potential in order to meet the requirements desired by consumers due to its high nutritional value and particular quality characteristics. The aim of the present study is to understand which quality determinants influence consumers’ decision making to consume avocado fruit in Italy. In the literature, avocado is a fruit few investigate from a consumers’ quality perception perspective. Therefore, understanding consumer preference for avocado fruit may be con…

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…

“Local Production”: What Do Consumers Think?

2022

Since the mid-1990s, there has been a growing interest among consumers and producers in downscaling to a local level the length of the agri-food chains as a solution for fairer and more sustainable food production systems. From the point of view of consumption, the attribute “local” is assuming an important role in defining food purchasing preferences, both in terms of expectations of product quality and in terms of its perceived relevance in determining the supply chain sustainability. This research aims to define how individuals’ perception of local production influences the definition of “local” among consumers based on a survey submitted to a sample of 500 consumers in North-Western Ita…

Single sensillum responses in Trissolcus basalis females to companion plant volatiles

2016

In food resources location and selection, parasitoid females spend considerable time examining the substrate with their antennae, where chemosensory, mechanosensory and thermo-hygroreceptive sensilla exist. Olfaction and perception of plant volatiles play a basic role in recognition of nutritional resources. For Trissolcus basalis, an egg parasitoid of the green stink bug Nezara viridula, previous electroantennography and behavioural experiments tested the parasitoid’s response to extracted headspace volatiles and a synthetic blend of buckwheat volatiles indicated that T. basalis females have sensitive and selective olfactory responses some major buckwheat, Fagopyrum esculentum, flower vola…

An assessment of regulation, education practices and socio-economic perceptions of non-native aquatic species in the Balkans

2021

Alongside climate change, the introduction of non- native species (NNS) is widely recognized as one of the main threats to aquatic biodiversity and human wellbeing. Non-native species and biodiversity are generally low priority issues on the political agendas of many countries, particularly in European countries outside the European Union (EU). The objectives and tasks of this study were to address the policy regulation, education level, education practices, and socioeconomic perceptions of NNS in the Balkans. A questionnaire based survey was conducted in Albania, Bosnia and Herzegovina, Montenegro, North Macedonia and Turkey (Balkan EU candidate and potential candidate members), in Croatia…

Human Visual Perception and Retinal Diseases

2010

Retinal diseases are causing alterations of the visual perception leading sometimes to blindness. For this reason, early detection and diagnosis of retinal pathologies is very important. Using digital image processing techniques, retinal images may be analyzed quickly and computer-assisted diagnosis systems may be developed in order to help the ophthalmologists to make a diagnosis. In this paper we described shortly two computer-assisted systems for the detection of retinal landmarks (optic disc and vasculature) together with a brief introduction to the human visual system and to some alterations of the visual perception caused by retinal diseases.

Indoor lighting quality: Effects of different wall colours

2016

This paper reports the results of measurements performed in a test room to investigate the impact of using different wall colours and light scenes on indoor lighting quality. Eye level spectral irradiances were measured for a user located inside the room and seated at a desk. These measurements allow the use of the Irradiance Toolbox, which makes it possible to calculate equivalent illuminances for the photopigments in the human eye. Moreover, the CIECAM02 colour appearance model was used to investigate the variations in hue and chroma values of the different wall colours when changing the light scene. The results demonstrate that there are significant variations in eye level spectral irra…
