According to the CPLL proteome sheriffs, not all aperitifs are created equal!

2014

Combinatorial peptide ligand libraries (CPLLs) have been adopted for investigating the proteome of a popular aperitif in Northern Italy, called "Amaro Branzi", stated to be an infusion of a secret herbal mixture, of which some ingredients are declared on the label, namely Angelica officinalis, Gentiana lutea and orange peel, sweetened by a final addition of honey. In order to assess the genuineness of this commercial liqueur, we have prepared extracts of the three vegetable ingredients, assessed their proteomes, and compared them to the one found in the aperitif. The amaro's proteome was identified via prior capture with CPLLs at two different pH values (2.2 and 4.8). Via mass spectrometry …

Potential application of yeasts from Ecuadorian chichas in controlled beer and chicha production

2021

The potential of yeasts isolated from traditional chichas as starter cultures, either for controlled production of the native beverage or for industrial beer production, has been investigated. Three S. cerevisiae strains and one T. delbrueckii strain isolated from four different Ecuadorian chichas were compared to ale and lager beer strains with respect to fermentation performance, sugar utilisation, phenolic off-flavour production, flocculation and growth at low temperature. Fermentations were performed in 15 °P all-malt wort and in a model chicha substrate at 12 °C and 20 °C. Tall-tube fermentations (1.5 L) were also performed with both substrates to assess yeast performance and beer qual…

The crime of consumption of alcoholic beverages in the Somali Penal Code

2021

Somalia is a Muslim country whose criminal law has been based on the 1930 Italian penal code to which some changes have been made to try to adapt it to the local context. One of these changes has been to introduce the crime of consumption of alcoholic beverages, a crime that anyway could be committed only by local Somali people due to their religious belief. This chapter analyzes this part of the Somali penal code trying to highlight the issues arising from the text of the law. The analysis is compared to the regime existing in the other Muslim African countries to understand similarities and differences with the Somali regulation. A conclusion is then drawn up also in view of a possible fu…

Date-rape evidence through fast determination of γ-butyrolactone in adulterated beverages.

2021

Abstract An infrared spectroscopy (IR) based methodology has been developed to determine γ-butyrolactone (GBL) in adulterated beverages. The proposed method permits the direct screening of GBL in beverages and involves a minimum sample treatment requiring less than 2 min for quantitative determination of GBL. Sensitivity of IR method was improved by using liquid-liquid extraction (LLE) providing detection limits of 0.023 mg g−1. Accuracy of the proposed methodology was evaluated through the analysis of soft beverages and alcoholic cocktails spiked with GBL at concentration levels ranging from 0.075 to 10 mg g−1 providing recovery values from 91 to 100%. GBL was determined in twelve blind-sp…

Alcoholic beverages, obesity, physical activity and other nutritional factors, and cancer risk: A review of the evidence

2016

International audience; Purpose: Prevention is a priority in the fight against cancers, especially nutritional prevention. To update the levels of evidence of relationships between 10 nutritional factors and cancer risk, the scientific literature published from 2006 to 2014 was reviewed by an expert group.Methods: Data from 133 meta-analyses, pooled analyses or intervention trials were examined. Nearly 150 relationships between nutritional factors and cancer at various sites were evaluated.Results: According to the evidence graded as convincing or probable, these factors were divided in two groups. Factors which increase the risk of cancer are alcoholic beverages, overweight and obesity, re…

Population Structure and Comparative Genome Hybridization of European Flor Yeast Reveal a Unique Group of Saccharomyces cerevisiae Strains with Few G…

2014

Wine biological aging is a wine making process used to produce specific beverages in several countries in Europe, including Spain, Italy, France, and Hungary. This process involves the formation of a velum at the surface of the wine. Here, we present the first large scale comparison of all European flor strains involved in this process. We inferred the population structure of these European flor strains from their microsatellite genotype diversity and analyzed their ploidy. We show that almost all of these flor strains belong to the same cluster and are diploid, except for a few Spanish strains. Comparison of the array hybridization profile of six flor strains originating from these four co…

L'arôme du gin : identification des composés clés et rôle des matières premières

2012

Le texte intégral de cette thèse est confidentiel à durée indéfinie.; Afin d’identifier les composés responsables de l’arôme du gin, une procédure GC-O-MS se basant sur la fréquence de détection a été développée. Elle a permis de déterminer l’intensité odorante des composés volatils. Leur qualité d’odeur a pu être définie par le développement d’une roue des odeurs utilisée pour catégoriser les descripteurs obtenus. Cette approche nous a dans un premier temps permis d’identifier les composés potentiellement importants pour l’arôme du gin. L’origine de ces composés a ensuite été déterminée par l’étude de la fraction volatile de différents « botanicals » appartenant à la recette du gin. Cette …

Alcohol and Nicotine Use among Adolescents: An Observational Study in a Sicilian Cohort of High School Students

2022

In recent years, the mode of alcoholic intake known as binge drinking (BD) has become a common practice, especially among adolescents who, due to socio-environmental motives, tend to reach a rapid state of drunkenness. This drunkeness leads to alterations in brain areas responsible for executive functions and cognitive processes, as well as to the genesis of factors that predispose to lasting addiction. Likewise, nicotine leads to a comparable degree of addiction. On this basis, the aim of this research was to evaluate, on a cohort of 349 high school students (15–17 years old) in the province of Palermo, the following: (I) the drinking model of alcoholic beverages; (II) the use of nic…

Nutrigenetics, nutrigenomics and phenotypic outcomes of dietary low-dose alcohol consumption in the suppression and induction of cancer development: …

2020

It is known that the intake of alcoholic beverages may impair genetic and epigenetic regulatory events with consequent crucial effects on cell phenotypes and that its association with selected genotypes can lead to a different risk of cancer in the population. The aim of this review is to pick up selected studies on this topic and recapitulate some of the biochemical and nutrigenetic/nutrigenomic aspects involved in the impact of dietary low-dose alcohol consumption on the switching-on or -off of tumorigenic pathways. These include i) the existence of predisposing or protective human genotypes and the relationship between dietary compounds and alcohol in the promotion or inhibition of carci…
