Inspections of accredited workshops: Some Italian experiences
Among the activities established by the Directive 128/09 and by NAP (National Action Plan), a periodical inspection by authorities is addressed to official workshops in charge of sprayer inspections.In this paper we describe activities carried out by two Italian regions (Umbria and Campania) that have recently started a regular activity for the inspection of workshops. An inspection procedure according to technical national guidelines (ENAMA documents) was prepared in collaboration with regional authorities and CRA-ING, that is in charge of technical aspects of inspections. The approach, the key elements and some results of inspections are reported in the paper
Italian traditional tomato varieties: a focus on the Campania region
[EN] The long tradition of tomato cultivation in Italy has allowed the
evolution of a wide diversity of traditional varieties or landraces that have
been cultivated for centuries and many of them are still common in the local
markets. Adaptation to peculiar climatic and edaphic conditions, the
geographical isolation of several growing areas, the specific agro-technique,
the local gardners’ selection, also based on consumers’s sensory preferences,
have resulted in groups of landraces distributed not only by region but also
by sub-regional areas. In most cases, the cultivation of these Italian
landraces covers very limited areas being carried out in family gardens for
personal consumption and/or in small-size farms that, therefore, play a key
role in the on farm maintenance of this precious germplasm, which in many
cases is risking extinction. The Campania region has been, and still is, an
important area for tomato production with a long tradition in the selection,
cultivation and processing of the crop, resulting in a rich reservoir of
valuable tomato landraces. So far, only three Italian tomato landraces have
been granted a Protected Geographical Status under European Union law,
the PGI “Pomodoro di Pachino” form Sicily, and the two PDOs “Pomodoro
S. Marzano dell'Agro Sarnese-Nocerino” and the “Pomodorino del Piennolo
del Vesuvio” from Campania. This short review will address some of the
most popular landraces of the Campania region, with a particular focus on
the two PDOs.[ES] La larga tradición del cultivo del tomate en Italia ha permitido la evolución de una amplia diversidad de variedades tradicionales o variedades autóctonas que han sido cultivadas durante siglos, muchas de las cuales siguen siendo comunes en los mercados locales. La adaptación a las peculiares condiciones climáticas y edáficas, el aislamiento geográfico de varias zonas de cultivo, las técnicas de cultivo específicas, la selección de los agricultores locales, también basada en las preferencias sensoriales de los consumidores, han dado como resultado grupos de variedades locales distribuidas no sólo por regiones, sino por áreas sub-regionales. En la mayoría de los casos, el cultivo de estas variedades autóctonas italianas cubre áreas muy limitadas y se están llevando a cabo en huertos familiares para consumo personal y / o en fincas pequeñas que, por lo tanto, desempeñan un papel clave en el mantenimiento de este valioso germoplasma, que en muchos casos está en peligro de extinción. La región de Campania ha sido, y sigue siendo, un área importante para la producción de tomate con una larga tradición en la selección, cultivo y procesamiento de este cultivo, resultando en un rico reservorio de variedades autóctonas de tomate valiosas. Hasta el momento, sólo tres variedades autóctonas de tomate italiano han obtenido el estatus de protección geográfica conforme a la legislación de la Unión Europea, la IGP “Pomodoro di Pachino” de Sicilia y las dos DOP “Pomodoro S. Marzano dell'Agro Sarnese-Nocerino” y “Pomodorino Del Piennolo del Vesuvio" de Campania. Esta breve revisión abordará algunas de las razas tradicionales más populares de la región de Campania, con especial atención a las dos DOP.This work was supported by the European Commission Horizon 2020 program (TRADITOM grant 634561 to S.G. and P.S.).Sacco, A.; Cammareri, M.; Vitiello, A.; Palombieri, S.; Riccardi, R.; Spigno, P.; Grandillo, S.

Identification of Flavescence dorée-related phytoplasma infecting grapevines on the isle of Ischia (southern Italy)
Among the grapevine diseases, Flavescence dorée (FD) is considered to be one of the greatest threats for grapevine cultivation throughout Europe. In Italy, where several major outbreaks of FD have occurred in the past, the disease is still mainly restricted to the northern regions and is under mandatory regulation. In 2011 the disease was recorded for the first time in southern Italy, in several vineyards located on the isle of Ischia (Campania). In order to determine the FD-related phytoplasma infecting these grapevines, molecular investigations were carried out on grapevine samples collected from several FD infected vineyards. The 16S rDNA/spacer region and the FD9 non-ribosomal fragment (secY gene) were investigated using a PCR/RFLP based method; a nucleotide sequence analysis of the FD9 amplified fragments was also carried out. The RFLP profiles obtained from all the analyzed samples showed the presence of FD-D phytoplasma type, on both 16S and secY genomic regions. Sequencing of the FD9 fragments showed a 99 % nucleotide sequence identity among the tested isolates and the various FD-D strains retrieved from the NCBI database.
Biocompounds recovery from Spirulina by conventional and ohmic heating methodologies: chemical and biological properties
Extracting the totality of bio-compounds with industrial interest from Cyanobacterium is often prevented by
the intrinsic rigidity of its cell wall. In this sense, the present study focuses on evaluating the influence thermal
batch extraction (conventional extraction technologies) and ohmic heating (OH) assisted extraction
(considered a greener alternative technology) in blue green microalgae Arthrospira platensis (Spirulina) cell
disruption for bioactive fractions recovery.
The proximal composition of Spirulina was initially determined. The maximum protein content (i.e., CPhycocyanin),
total carbohydrates (TC) and total phenolic compounds (TPC) extracted in water at different
times (30-120 min) and temperatures (30-51 ºC) was quantified after the conventional and OH- assisted
extraction. The freeze-thawing process was used as control. The antioxidant activity (i.e., FRAP and DPPH
assays) of the obtained extracts was assessed.
Results showed that with the freeze-thawing process, traditionally used for the recovery of bio- compounds
from Spirulina, the concentration of C-phycocyanin was approx. 42 mg/g of Spirulina, 26 mgGlcE/g Spirulina
of TC and 9 mgGAE/g Spirulina of TPC. Using OH-assisted extraction, the maximum of C-Phycocyanin
content obtained was 45 mg/g of Spirulina (obtained at 37 ºC, 30 min), the maximum carbohydrates content
was 40 mgGlcE/g Spirulina and the maximum TPC was 10 mgGAE/g Spirulina. On the other hand, using
conventional thermal treatment it can be observed that, under the same conditions, the bioactive compounds
recovery decreased to 35 mg/g, 20 mgGlcE/g Spirulina for C-phycocyanin concentration and TC (p<0.05),
respectively. The concentration in phenolic compounds is not so affected, but even so the ohmic heating
potentiates the extraction of these secondary metabolites.
The antioxidant activity of the extracts there was not different between conventional treatments andOH.
Thus, the results indicated that OH is a good alternative to conventional methods aiming at the extraction of
intracellular components with a decrease in processing time and energy costs associated with the extraction
process, which together with an easy upscale make OH an interesting methodology for use in the industrial
production of microalgae colorants and bioactive supplements.info:eu-repo/semantics/publishedVersio
The effect of novel biodegradable films on agronomic performance of zucchini squash grown under open-field and greenhouse conditions
The soil mulching is an important agricultural practice for increasing crop productivity and earliness. Mulching can be made with natural or synthetic materials. The common films being used these days are usually made of low density polyethylene (LDPE), but its disposal can represent a serious environmental and economic problem. The biodegradable mulching can overcome these problems. Two experiments were carried out comparing the effects of biodegradable and LDPE mulching films on yield and quality of zucchini (Cucurbita pepo L.) grown in two environments (open-field vs. greenhouse). In both the environments a randomized complete block design was adopted. The treatments composed of no-mulched crop (control), soil covered by 15 microns black biodegradable film (MB15) and soil covered by 50 microns black LDPE film. The results showed that MB15 was able to maintain discrete technical proprieties until the end of cycle, especially in greenhouse, assuring a sufficient heating of soil, similar to LDPE. The soil heating promoted crop development. Furthermore, earliness was increased (84 in greenhouse vs. 99 days in open air) in greenhouse. The early production of zucchini grown on MB15 was similar to the one in LDPE production in greenhouse. The total marketable yield of plants grown on both films was not different but it was lower in open air. The biodegradable film significantly improved fruits quality, with higher values of firmness and total soluble solid than fruits grown on LDPE
Identification of the Red-Necked Longhorn Beetle Aromia bungii (Faldermann, 1835) (Coleoptera: Cerambycidae) with real-Time PCR on frass
Aromia bungii (Faldermann, 1835) (Coleoptera: Cerambycidae), the red-necked longhorn beetle is native to eastern Asia, where it is an important wood-borer of fruit and ornamental species of the genus Prunus. A. bungii is a quarantine pest in the European Union, following its accidental introduction and establishment in Germany and Italy, and is currently included in the list of priority pests. To confirm its infestations in outbreak areas, adult or larval specimens are needed to perform morphological or molecular analyses. The presence of A. bungii larvae inside the attacked trees makes the collection of specimens particularly difficult. Thus, we present two diagnostic protocols based on frass analysis with real-time PCR (probe and SYBR Green). The results obtained show that a non-invasive approach for detecting the presence of this harmful invasive pest can be a reliable and accurate alternative diagnostic tool in phytosanitary surveys, as well as to outline a sustainable pest management strategy
Incorporation of waste orange peels extracts into PLA films
An important and hot-topic field in food packaging is the development of innovative active packaging, based on the incorporation of specific components, such as antioxidant and/or antimicrobial agents, able to modify the internal atmosphere or to be absorbed directly by the food, in order to prolong the product shelf-life. However, due to the increasing concerns of consumers about the plastics and the presence of synthetic chemical compounds in consumer goods, as well as, the importance of increasing environmental sustainability of the materials, has encouraged novel developments. This study is focused on the development of innovative, biodegradable and sustainable PLA-based active packaging solutions with the incorporation of natural antioxidant compounds recovered from agri-food wastes. An antioxidant extract was recovered through hydro-alcoholic extraction from waste orange peels, purified by resin absorption process and formulated as freeze-dried extract or spray-dried with pectin or cyclodextrins as carrier material. These three different formulations were incorporated into PLA films at different concentrations to investigate the influence of extract addition on polymer thermal stability and on colour and mechanical properties of films under accelerated light storage conditions
Sorption Enhanced Water Gas Shift for H2 production using sour gases as feedstock
Even though hydrogen is considered the future of energy carrier, it is still produced from fossil fuels therefore with no benefits for the CO2 emission reduction. This paper discusses an innovative concept for hydrogen production which combines the Acid Gas to Syngas (AG2S (TM)) concept and the Sorption Enhanced Water Gas Shift (SEWGS) process. The AG2S (TM) process produces H-2 and elemental Sulfur from H2S and CO2, then H-2 purification is performed through amine scrubbing. The SEWGS technology is a Pressure Swing Adsorption process where the CO2 and H2S are adsorbed on hydrotalcite-based material. With respect to amine scrubbing, SEWGS takes advantage of a higher operating temperature of 350 degrees C -400 degrees C which reduces temperature swing losses, lower regeneration energy and the possibility to recycle the H2S while capturing the CO2. This study aims at exploring the potential of the SEWGS technology by means of the evaluation of detailed mass and energy balances, showing the potentialities of the AG2S (TM)+SEWGS technologies which more than double the H-2 production efficiency (25.0%) with respect to the amine scrubbing configuration (10.7%). Including the steam production, the overall process efficiency can be higher than 90% which is again more than twice the value of the AG2S (TM) reference case. (C) 2019 The Author(s).

Sensory traits and consumer’s perceived quality of traditional and modern fresh market tomato varieties: A study in three European countries
Consumer dissatisfaction with the flavor quality of many modern fresh market tomato varieties has fostered breeders’ interest in sensory quality improvement, and the demand for traditional varieties, which are generally associated with better flavor. To achieve further knowledge on the factors influencing the sensory quality and consumers’ preferences and perception, European traditional and modern fresh market tomato varieties were grown and evaluated in France, Italy, and Spain. Different growing conditions were tested in France (soilless vs. soil) and in Spain (open field vs. greenhouse), while in Italy fruits were evaluated at two ripening stages. Fruit quality was assessed by integrating physicochemical analyses, sensory profiles, and consumer tests. In all three countries, overall modern varieties were perceived as having more intense “tomato flavor” and “overall flavor” than traditional ones. In France and Spain, consumers’ preferences were more oriented towards modern varieties than traditional ones. Significant growing condition effects were found on sensory and physicochemical traits, while the effect on consumers’ overall liking was not significant, largely depending on the genotype. A fair agreement between product configurations from descriptive analysis by trained assessors and Check-All-That-Apply (CATA) questions by consumers was observed. Penalty-lift analysis based on CATA allowed identifying positive and negative drivers of liking.Postprint (published version
