Prologue - Book of Abstracts - Foodinnova 2017
No full textAfter Spain, China and Argentina the Foodinnova Conference docks at Cesena, in Italy, hosted by the Alma Mater Studiorum Università di Bologna, which is considered one of the oldest universities in the world. Indeed, the courses of Food Science and Technology and the research groups in food science and engineering, among the best in Italy and Europe, belong to the University Campus of Cesena.
The region where Cesena is situated, Emilia Romagna, is the first in Europe for the number of EU certified typical and traditional foods PDO and PGI. Nevertheless many food industries are working and continuously developing new foods based on fruit, vegetable and meat products with excellence in quality and management (many of them run co-operatively), establishing themselves as leaders in different food chains. Furthermore, Emilia Romagna is also proud of its food machinery industries that combine the best of technological innovation and industrial practice by the use of high precision mechanics and refined ICT.
Consequently, the location chosen for the conference could not have been better. Cesena is a small town in a rural area where the agriculture coexists with highly organized touristic industries, advanced mechanics, high level gastronomic offerings and hospitality, in keeping with the concept of the "wellness valley".
More than 200 participants from all over the world and 20 highly qualified speakers bring the scientific value of the conference to the highest possible level.
Thus, Foodinnova once again brings the paradigm of innovation to improve quality, sustainability and the social and economical role of food production, from traditional foods to the consumer demand for more sustainable, healthier and tastier food products in everyday life.
This edition of Foodinnova introduces topics such as foodomics, packaging, bioe- conomy, hygienic design and rules harmonization and these scientific arguments will go to make up the core of the conference, as food engineering, food safety and quality. This opening approach shall be the keyword for the integration of different disciplines in a multidisciplinary view where the concept of food engineering will be called upon to break borders

Elimination of Salmonella cross-contamination on eggs using antimicrobial coating
No full textGastro-intestinal infections caused by Salmonella strains, together with Campylobacter, are among the most common food-borne diseases in Italy (EFSA journal 2016). Therefore, it is important to avoid the spreading of bacterial colonization on different type of foods. A common vector of Salmonella are eggs, which can be contaminated by the laying hen (vertical or horizontal infection) or by contact with contaminated eggs of food (cross-contamination). At the moment, the Italian prevention practices to control Salmonella spreading are bacterial controls on laying hens and their environment and eggs brushing before packaging. Other countries allow eggs washing, but this process decreases the shelf-life of the product. This study investigates the efficiency of an antimicrobial coating to avoid Salmonella cross-contamination on eggs.
Coating the eggs with a pectin-alginate polymer drastically improves their food safety and reduces the recovery of Salmonella colonies from the egg surface. Therefore, the occurrence of cross-contamination would be highly reduced as well. The positive effect of the coating itself showed to be highly effective even without the addition of antibacterial agents such as LAE. This active packaging could guarantee higher safety for eggs and opens the possibility to test this procedure on other food matrices common carriers of potentially pathogenic bacteria
Health-promoting and anti-inflammatory properties of pomegranate: the latest evidence from the literature
Get PDFIntroduction. Ellagitannin (ET)-rich fruits as pomegranate have demonstrated positive health properties related to oxidative stress and inflammatory effects. Interest in dietary (poly)phenols, including ETs, considerably intensified after the recognition of their potential health benefits. A recently published study has suggested that urolithin A, gut microbiota-derived metabolite of ETs, increased the lifespan of roundworms by a half and improved muscle function in rodents [1].
Materials and Methods. This work provides a brief overview of the evidence from in vivo studies investigating potential anti-inflammatory effects of pomegranate, with an emphasis on fruit-derived juices. This summary was compiled by examining studies identified from databases as PubMed focused on inflammation and/or inflammatory-associated conditions. Inflammation is a complex biological response to tissue injury or infection. Chronic inflammation has been shown to be involved in the onset and development of a range of diseases, as arteriosclerosis, obesity, diabetes, and neurodegenerative diseases.
Results. The number of peer-reviewed journal articles is greatly increased in the last years, and several human clinical trials are in progress (https://clinicaltrials.gov/). To date, research studies on the promising health effects of pomegranate have advanced rapidly. Most of the published works are related to prostate cancer, diabetes, and atherosclerosis; few researches are focused on other pathological conditions. Intervention studies have been carried out using pomegranate juice or whole fruit (poly)phenol extracts.
Conclusions. The present summary of the current science indicates that pomegranate juice shows promising potential for reducing inflammatory-related conditions by the improvement in anti-inflammatory responses. Therefore, consuming pomegranate juice, as part of a healthy balanced diet, should be encouraged.

Valorization of ginger and turmeric peels
No full textThe Zingiberaceae family includes ginger (Zingiber officinale) and turmeric (Curcuma longa) zhizomes which are primarily used in the dried spices or essential oil production and are widely recognized for their health benefits due to their strong anti-inflammatory and antioxidant activities. This work is aimed to investigate the antioxidant potential of ginger and turmeric peels which are usually discarded during post-harvest operations.The total phenolic contents and the antioxidant activities of the extracts obtained from the powdered peels of ginger and turmeric rhizomes resulted in statistically relevant differences (P≤0.0001) depending on the Zingiberaceae species and extraction method. In details, the ethanol extraction compared with infusion and sonication techniques was more effective in increasing their antioxidant activities based on DPPH (4.16, 2.17, 2.17 mg TE/g, respectively) and FRAP (65.07, 18.81, 15.49 mg TE/g, respectively) assays because of higher yields of phenolic substances (78.73, 36.84, 33.08 mg GAE/g, respectively) such as 6-gingerol (12.78, 0.41, 0.58 mg/g, respectively) and curcumin (48.62, 5.42, 1.38 mg/g, respectively) detected by HPLC analysis in ginger and turmeric extracts, respectively. Moreover the ethanolic extracts of turmeric peels showed the better performances than those of ginger peels with higher amounts of phenolic substances (104.88, 52.57 mg GAE/g, respectively) and consequently greater antioxidant activities based on DPPH (4.45, 3.87 mg TE/g, respectively) and FRAP (72.38, 57.77 mg TE/g, respectively) assays. In conclusions, the discarded peels of ginger and turmeric rhizomes can be recovered as a source of natural antioxidants not only in food additives but also cosmetic and medicinal product
Fatty acids profile and Viscosity of Sunflower oil treated with ozone
No full textOzone is an emerging eco-friendly technology. In this work the effect of ozonation at different time periods on the fatty acids profile and viscosity of sunflower oil has been investigated. Results show that ozone treatment did not affect the amount of the unsafe trans fatty acids. Therefore ozonation could be considered a tool to modify the fatty acid chains without the presence of unsafe trans fatty acids. In addition the lower degee of insaturation and the presence of compounds higher in molar mass contribute to increase the viscosity of sunflower oil which may be a suitable ingredient for new formulations
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
