Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces

2021

Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…

Genetic variation of an Italian long shelf-life tomato (Solanum lycopersicon L.) collection by using SSR and morphological fruit traits

2014

The recovery of ancient germplasm in tomato (Solanum lycopersicon L.) has become necessary to limit the wide genetic erosion caused by the employment of modern cultivars. Among germplasm collections, long shelf-life landraces could represent an important source of biodiversity. The present study provides a first set of molecular and phenotypic data on long shelf-life (so called "da serbo" in southern Italy) tomato collection, mainly originated from Sicily together with some landraces from Campania and Apulia. The analysis of fruit traits showed a low intra-varietal variation, while exhibiting a quite higher inter-varietal variability. Overall, the cultivars have been classified in six fruit…

Spaghetti Enriched with Inulin: Effect of Polymerization Degree on Quality Traits and α-Amylase Inhibition.

2022

Inulin is considered a dietary fiber and represents a noteworthy ingredient for food biofortification due to its health effects and its neutral taste. The aim of the work was the evaluation of the quality of pasta produced using whole-meal flours of two ancient Sicilian landraces (Senatore Cappelli-CAP and Timilia—TIM) fortified with two types of inulin (long-chain topinambur inulin IT and low-chain chicory inulin IC), at two different levels of substitution (2 and 4%) to evaluate its possible effect on α-amylase inhibition. The color indices L* and a* were mainly influenced by cultivars, while IT improved the sensory attributes, mainly the elasticity sensation, and influenced l…

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…

In situ preservation of local landraces of faba bean (Vicia faba L.) and utilisation of their food products in central regions of Serbia

2012

International audience; Today, faba bean (Vicia faba L.) in Serbia is almost completely replaced with Phaseolus beans and has become a neglected crop with no official data. A recently launched action of the Institute of Field and Vegetable Crops and the Faculty of Agriculture in Novi Sad is aimed at the identification of the regions in Serbia where faba bean, known in Serbian as bob, could still be found. This was essentially enhanced by the multilateral project ECO-NET 18817 Search for new genetic variability in pea (Pisum sativum) and faba bean (Vicia faba L.) to support the development of sustainable agricultures, with duration in 2008 and 2009 and involving partners from France, Bulgari…

Economical Issues Regarding the Implementation and Functioning of the Common Catalogue of Varieties of Agricultural Plant Species

2013

Abstract Economical constraints regarding the full implementation and functioning of the common catalogue on plant genetic resources for food and agriculture (PGEFA) are discussed in this paper based on the assessment of the current European Union regulatory framework. Based on this article's results new financial mechanisms should be developed at the national level for further responding to the European requirements including measures regarding the conservation varieties. This assessment is further supporting the need for developing and implementing new financial mechanisms in the support of the poor rural populations as well as for small farmers in harmony with commercial agriculture.

Trophic relationships between the cultivated plant and arbuscular mycorrhizal fungi. Importance of arbuscular mycorrhizal fungi on plant production (…

2018

French : Dans son environnement, la plante interagit sans cesse avec des microorganismes. Elle est confrontée à une variété de microorganismes bénéfiques, neutres ou pathogènes, qui sont fortement dépendants des ressources carbonées que la plante libère dans le sol, leur conférant ainsi un apport de nutriments et d’énergie nécessaire à leur développement. La mycorhize à arbuscules est une symbiose mutualiste formée par 80% des plantes terrestres datant de l’Ordovicien, i.e. environ 450 millions d’années avant notre ère. L’ensemble des travaux de recherche présenté au sein de ce manuscrit, s’inscrit dans le cadre de deux objectifs généraux : (i) acquérir une meilleure compréhension des mécan…

MORPHOLOGICAL AND GENETIC CHARACTERIZATION OF A LARGE COLLECTION OF ITALIAN TOMATO LANDRACES

2016

Increased interest towards traditional tomato varieties is fuelled by the need to rescue desirable organoleptic traits and to improve the quality of fresh and processed tomatoes in the market. In addition, the phenotypic and genetic variation preserved in tomato landraces represents a means to understand the genetic basis of traits related to health and organoleptic aspects and to breed them in modern varieties. In the frame of Horizon 2020, the TRADITOM project "Traditional tomato varieties and cultural practices: a case for agricultural diversification with impact on food security and health of European population" (http://traditom.eu/) aims to the collection, characterization and valoris…

Valutazione produttive e qualitative di Timilie - Produttive and qualitative evaluation of timilie

2009

Riassunto: Gli autori riportano i primi risultati produttivi e qualitativi relativi a 4 popolazioni di timilie raccolte in diversi ambienti pedoclimatici della Sicilia occidentale. Attraverso uno schema sperimentale non ripetuto sono state valutate 720 accessioni ed è emersa una elevata variabilità tra e intra popolazioni. Dalle analisi qualitative delle accessioni collezionate sono emerse peculiari caratteristiche qualitative della granella che ne fanno intravedere l’uso sia per la produzione di prodotti tipici sia per il trasferimento in varietà ampiamente diffuse e coltivate. Abstract: Productive and qualitative results on four “timilia” population from different West Sicilian pedoclimat…
