Innovation for the Italian agricultural and food industry sector

2020

The food industry is one of the largest energy consumers in the world, with 95 EJ/year. In this context, in Europe the amount of energy needed to cultivate, process, package and bring food to the homes of citizens reached 285 Mtoe in 2015, of which 14 Mtoe due to the Italian agricultural and food system. With the aim of favoring a drastic reduction in energy consumption, the European Commission, and the main international agencies, ie: FAO, OECD, UN over the last decade have aligned on the need to develop policies to support energy efficiency, renewable energies and sustainable technologies in order to minimize the use of fossil fuels and to reduce the final energy consumption, especially i…

Biodiversity and dairy traits of lactic acid bacteria from foliage of aromatic plants before and after dehydration process monitored by a smart senso…

2020

ABSTRACT The main hypothesis of this work was to evaluate the presence of lactic acid bacteria (LAB) intrinsically resistant to plant essential oils in sage (Salvia officinalis L.) and laurel (Laurus nobilis), for future applications in functional cheese production by addition of aromatic herbs. The effect of the drying process on the viability of LAB was evaluated with three biomass densities (3, 4 and 5 kg/m2). The drying densities did not affect weight loss, but influenced the levels of LAB of sage and laurel. A total of 10 different strains of Enterococcus faecium, Enterococcus mundtii, Enterococcus raffinosus and Leuconostoc mesenteroides were identified from laurel, while sage did not…

A decision support system based on multisensor data fusion for sustainable greenhouse management

2018

The sustainable exploitation of natural resources is nowadays an important challenge for governments and institutions, considering the expected increase of the world population. In order to respond to this emergent criticality, the principles of green economy have been introduced in the European policy discussion to achieve a good compromise between the sustainability and the profitability of productions by increasing the efficiency of farming operations. Such approach poses some technical and financial challenges for small-sized enterprises because they generally do not possess adequate internal knowledge, nor they can acquire external expertise due to their budget restrictions. Decision S…

Quality evaluation of grapes for mechanical harvest using vis NIR spectroscopy

2019

Mechanical harvest of grapes is one of the operations that mostly influence the quality of the future wine. The shaking frequency of the harvesting machine is usually adjusted on the basis of the grape berry characteristics in order to limit grape juice production that is a potential cause of uncontrolled fermentations. These evaluations usually require time, personnel and laboratory analyses. The introduction of a vis NIR system to rapidly and reliably evaluate the berry properties in field before mechanical harvest could be a good alternative. The aim of this study was to evaluate the feasibility of applying vis NIR spectroscopy as a non-destructive technique on grapes cv. Syrah and Chard…

STUDY ON THE TUNNEL PASTEURIZER ON TABLE OLIVES PROCESSING

2015

The application of heat treatment is particularly important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. However, heat treatments can be cause of deterioration of many quality parameters of agro-food products, including texture, intended as the consistency of the pulp. In this study 'Nocellara del Belice' table olives produced in 2010 and packaged in glass jars were subjected to pasteurization at industrial scale using a tunnel pasteurizer with a core temperature of 75°C for 8 min. The aim of the study was to mechanically evaluate the pulp texture evolution that contributes …

Optimising the efficiency of olive harvesting considering operator safety

2019

Mechanical-assisted harvesting of olives, which is carried out using hand-held harvesting units that detach the drupes through vibration supplied by electric motor or combustion engines, is a widespread method used in southern Italy. Such machines are able to harvest more than 80% of the overall quantity of olives available per tree in 5–10 min, but their performance is influenced by several factors related to the mechanical characteristics of the device and to the features of the trees. Here the problem of optimising harvesting efficiency whilst minimising the health risks to the operators is investigated, with the aim of demonstrating that it is possible to determine an optimum harvesting…
