Effect of seasonality on physico-chemical and microbiological properties of nicastrese milk and artisanal cheese
2021
ABSTRACT Nicastrese is an indigenous Italian goat breed reared in the Calabria region under semi-extensive practices. From January to June, the milk yield of 400 multiparous Nicastrese goats was evaluated. In addition, tank milk and ripened cheese samples were subjected to physico-chemical and microbiological analyses with the aim to assess the effect of the seasonality on quality parameters. The volatile organic compounds profile of the ripened Nicastrese cheese samples was evaluated. Results showed that the seasonality had a significant effect on milk fat, lactose, urea, citric acid contents and acidity. Microbiological analysis of tank milk samples revealed variability among the differen…
Is It Possible to Produce Certified Hazelnut Plant Material in Sicily? Identification and Recovery of Nebrodi Genetic Resources, in vitro Establishme…
2021
Eight Sicilian cultivars of hazelnut (Corylus avellanaL.), namely-Curcia, Nociara Collica, Panottara Collica, Panottara Galati Grande, Parrinara, Panottara Baratta Piccola, Enzo, and Rossa Galvagno, registered into the Italian Cultivar Register of fruit tree species in 2017 were selected from Nebrodi area and establishedin vitro. The aim of the work was to carry out the sanitation of the cultivars and get virus-free plants from the most important viral pathogen threat, theapple mosaic virus. Virus-free plant material is essential for the production of certified plants from Sicilian hazelnut cultivars, complying the CE (cat. CAC) quality and the technical standards established in 2017 for vo…
In Vitro Regeneration of
2019
Three caper (Capparis spinosa L.) biotypes grown on the Sicilian island of Salina (38°33′49″ N) were micropropagated to evaluate two different in vitro culture systems: one using the traditional solid medium, and the other based on liquid culture in a PlantForm bioreactor. PlantForm is a temporary immersion system (TIS), a new propagation method in which the shoots undergo temporary immersion in a liquid medium in order to avoid the accumulation of gas through forced ventilation. This study proposes a protocol to improve the efficiency of in vitro propagation of caper plants, while also reducing production costs, because of the elimination of the gelling agent, and manual labor, requiring l…
Le varianti A1 e A2 della ?-caseina non hanno un effetto significativo sul microbiota del latteThe A1 and A2 ?-casein variants have not impact on mil…
2020
Objective: Milk is composed by a complex microbiota which can be influenced by numerous factors such as the season, the diet, the type of litter, the facility. As well, the animal's genotype can affect the composition of the milk microbiota. In milk, ?-casein is characterized by a high-level of polymorphism. The aim of this study was to verify if A1 and A2 ?-casein variants could in- fluence the milk microbioma. Materials and methods: Thirty Holstein cows were genotyped for ?-casein locus and divided into three groups. In two different sea- sons, milk samples (individual and bulk tank for each experi- mental group) and mozzarella cheese were collected separately from each group. Bacterial D…
Discrimination of almonds (Prunus dulcis) geographical origin by minerals and fatty acids profiling
2016
Twenty-one almond samples from three different geographical origins (Sicily, Spain and California) were investigated by determining minerals and fatty acids compositions. Data were used to discriminate by chemometry almond origin by linear discriminant analysis. With respect to previous PCA profiling studies, this work provides a simpler analytical protocol for the identification of almonds geographical origin. Classification by using mineral contents data only was correct in 77% of the samples, while, by using fatty acid profiles, the percentages of samples correctly classified reached 82%. The coupling of mineral contents and fatty acid profiles lead to an increased efficiency of the clas…
Understanding Consumers’ Convenience Orientation. An Exploratory Study of Fresh-Cut Fruit in Italy
2021
In Western society, the fresh-cut fruit market is experiencing significant growth, especially in Italy, where, in 2019, the fresh-cut fruit sales volume increased by 35% compared with the previous year. This study aims to understand Italian consumers&rsquo
Brain Opioid Activity and Oxidative Injury: Different Molecular Scenarios Connecting Celiac Disease and Autistic Spectrum Disorder
2020
Celiac Disease (CD) is an immune-mediated disease triggered by the ingestion of wheat gliadin and related prolamins from other cereals, such as barley and rye. Immunity against these cereal-derived proteins is mediated by pro-inflammatory cytokines produced by both innate and adaptive system response in individuals unable to adequately digest them. Peptides generated in this condition are absorbed across the gut barrier, which in these patients is characterized by the deregulation of its permeability. Here, we discuss a possible correlation between CD and Autistic Spectrum Disorder (ASD) pathogenesis. ASD can be induced by an excessive and inappropriate brain opioid activity during the neon…
Identification et caractérisation de candidats d’origine naturelle à action herbicide pour contrôler les adventices
2016
EASPEIPMGESTADAGROSUPINRA; The use of herbicides to control weeds is very common. However, some herbicides are both environmentally detrimental and human unhealthy. The use of microorganisms acting as natural herbicide could be an alternative control method. Symptomatic weeds will be collected in field. Microorganisms will be isolated from symptomatic weeds, purified, identified and inoculated on weeds to confirm Koch’s postulates. The identified pathogenic microorganisms will be tested against a selection of weeds and crops to characterize the host range and the specificity of these microorganisms. In parallel, the diversity of endophytic microorganisms of symptomatic weeds will be charact…
Characters with multiple usages- phenotypic variability analysis at Echinacea purpurea (L.) Moench species
2010
Merging aesthetics with utility, some medicinal plants can benefit both of a high production and decoration potential. This calls for diversification of improvement directions of the species. Through this article we suggest one of these species, Echinacea purpurea (L.) Moench. This is considered to be important at this time, acquisition of new biological forms - varieties in this species, which show multiple attributes utility based on key biological characteristics, agronomic, physiological, biochemical and agrochemical (medicinal, decorative, culinary etc.). To achieve this goal, studies were undertaken, given in this article, which is the starting point for selecting characters represent…
