Innovative and Sustainable Food Business Models
2019
Companies are called upon to solve the great challenges of the new millennium. The food sector, from this point of view, plays a strategic role. Poverty, malnutrition, hunger, climate change, and social inequalities are just some of the trends which the agri-food sector has to cope with. The digital transformation that companies will need to embrace to survive requires new ways of creating, thinking, and working with technology-driven tools to provide value for their businesses and customers. Digitization, whether it pertains to new technologies, the analysis of big data or the development of on-line and spatial applications, can contribute to achieving systemic food production transformati…
Linking scientific and practical knowledge in innovation systems
2011
New research indicates that firms combining the science-based STI (Science, Technology, Innovation) and the experience-based DUI (Doing, Using, Interacting) modes of innovation are more efficient when it comes to improving innovation capacity and competitiveness. With regard to innovation policy, the STI mode calls for a supply driven policy, typically aimed to commercialise research results. The DUI mode suggests a demand driven policy approach, such as supporting the development of new products or services to specific markets. This paper analyses how the two types of innovation policy and the two innovation modes can be combined in regional innovation systems. The analysis builds on studi…
QUALITY AND PRICES OF INTRA-EUROPEAN TRADE OF FOOD-INDUSTRY PRODUCTS
2000
The completion of the European Single Market should bring out an exploitation of comparative advantages in production and trade. It is usually assumed that, given the predominance of intraeuropean trade flows in the global import figures of the European Union, efficiency gains from trade creation could be potentially important. However, the analysis of the effects of the Single Market on trade specialisation with a greater degree of accuracy requires trade quality indicators to be available. This paper uses the theory of index numbers to establish the relative quality levels of the food industry shipments to the European Internal Market from European Union member countries. It is found a po…
Ascorbic Acid determination using linear sweep voltammetry on flexible electrode modified with gold nanoparticles and reduced graphene oxide
2020
Indium tin oxide (ITO) coated on flexible polyethylene terephthalate (PET) substrate electrode was modified with reduced graphene oxide and gold nanoparticles by simple co-electrodeposition performed at -0.8 V vs SCE for 200 s. All samples were characterized by electron scan microscopy. The as prepared electrode was used as electrochemical sensor to selective detection of ascorbic acid using linear sweep voltammetry. Excellent results were obtained in a linear range from 20 to 150 µM of ascorbic acid with a limit of detection of about 3.1 µM (S/N=3.3). The sensors have a reproducibility of about 5.5% and also show high selectivity towards different interferents such as chlorine, calcium, ma…
Combined Innovation Policy: Linking Scientific and Practical Knowledge in Innovation Systems

Study and characterization of polyphenol oxidase from eggplant (Solanum melongena L.)
2011
ABSTRACT: In this study the catecholase and cresolase activities of eggplant polyphenol oxidase (PPO) were investigated. Enzyme activity was determined by measuring the increase in absorbance using catechol as substrate and 3-methyl-2- benzothiazolinone hydrazone (MBTH) as coupled reagent. The effects of substrate specificity, heat inactivation, temperature, pH, and inhibitors were investigated to understand the enzymatic alteration of ready-to-eat preparations. Browning of vegetables was determined through a colorimeter. Decrease of lightness (L*) and increase of color difference values (ΔE*) were correlated with tissue browning. Antibrowning agents were tested on PPO under the same condit…
Sicilian potential biogas production
2013
This study is aimed at predicting the Sicilian potential biogas production, using the Organic Fraction of Municipal Solid Waste (OFMSW), animal manure and food industry by-products, in a region where only one biogas plant using MSW and one co-digestion plant are nowadays available. The statistical data about OFMSW, the number of animals bred in medium and large farms and the amounts of by-products of food processing industries were evaluated, in order to compute the Sicilian potential biogas and energy production. The OFMSW produced in Sicily, that is 0.8 million tons ca. per year (37% of MSW), could be used in a bio-reactor, together with other raw materials, for Anaerobic Digestion (AD) p…
Water Reuse in the Food Industry: Quality of Original Wastewater Before Treatments
2017
This chapter introduces one of the most important emergencies in the world of food and non-food industries: the availability of clean and drinking water. Water use has more than tripled globally since 1950: water quality and its scarcity are increasingly recognised as one of the most important environmental threats to humankind. In addition, the food and beverage processing industry requires copious amounts of water. For these reasons, direct and indirect water reuse systems are becoming more and more interesting and promising technologies. Different reuse guidelines have been recently issued as the result of risk assessment and management approaches linked to health-based targets. Chemical…
Fishery-induced selection for slow somatic growth in European eel
2012
International audience; Both theoretical and experimental studies have shown that fishing mortality can induce adaptive responses in body growth rates of fishes in the opposite direction of natural selection. We compared body growth rates in European eel (Anguilla anguilla) from three Mediterranean stocks subject to different fishing pressure. Results are consistent with the hypotheses that i) fast-growing individuals are more likely to survive until sexual maturity than slow-growing ones under natural conditions (no fishing) and ii) fishing can select for slow-growing individuals by removing fast-growing ones. Although the possibility of human-induced evolution seems remote for a panmictic…
