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…

RESPONSE OF MELON GENOTYPES TO POLYETHYLENE AND BIODEGRADABLE STARCH-BASED MULCHING FILMS USED FOR FRUIT PRODUCTION IN THE WESTERN COAST OF SICILY

Influence of grain quality, semolinas and baker’s yeast on bread made from old landraces and modern genotypes of Sicilian durum wheat

2021

Abstract Several studies showed that products made with ancient wheat genotypes have beneficial health properties compared to those obtained with modern wheat varieties, even though the mechanisms responsible for the positive effects are not clear. Ancient durum wheat genotypes are being currently used for the production of pasta, bread and other typical bakery products but the consumption is strictly local. In this work 15 genotypes of Triticum turgidum subsp. durum, including 10 ancient and 5 modern, were characterized for their technological traits through the determination of different parameters: protein content, dry gluten, gluten index, yellow index, ash, P/L, W and G. In addition, t…

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…

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…

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…

Epoche d'impianto e sistemi di allevamento per il fagiolo "Badda"

2010

The bean landrace"Badda" has been cultivated since long ago in the Madonie mountains in the northern side of Sicily.It is characterized by a bush indeterminate habit and comprises two ecoty termed 'Badda bianca ' and 'Badda nera' according to the seed colour. This paper describes the results of a study on the effects of four sowing dates (June 15 and 30, July 15 and 30) and two vertical training sustems 8a frame of Arundo donax dry canes or a trellis consisting of several strands of wire) on productivity of the phaseolus landrace 'Badda bianca'. Marketable yields obtained from 15 june sowing were significantly higher than those from June 30 and July 15 sowing dates which in turn were signif…

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…

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…
