New Method of DNA Isolation from Two Food Additives Suitable for Authentication in Polymerase Chain Reaction Assays

2005

Locust bean gum and guar gum are galactomannans used as additives (E 410 and E 412, respectively) in the food industry as stabilizing agents. Analytical discrimination between the two additives in gums and foods is now feasible by molecular techniques. However, only complex and time-consuming DNA isolation protocols are available to date. We have developed simple improved protocols to obtain enough DNA suitable for PCR amplification from a few milligrams of commercial E 410 and E 412 additives (containing more than 75% polysaccharides). The suspension of additives in water or 10 mM Tris-HCl, pH 8.5, efficiently recovers DNA suitable for authentication in PCR assays. However, the Tris method…

Alternative feed resources and their effects on the quality of meat and milk from small ruminants

2008

The present paper reviews the quality of meat and milk from sheep and goats offered alternative feeds as a replacement for concentrates. Legume seeds and pods, shrubs, local agro-industrial by-products or novel pasture species are cheap and widely available in Mediterranean countries and are suitable for sheep and goat nutrition. Many of these alternative feed resources (AFR) contain secondary compounds, such as tannins. Tannin-containing feeds result in meat of a lighter colour and tend to increase milk yield and protein content, probably because they protect dietary proteins from ruminal degradation. Conjugated linoleic acid (CLA) content in kid meat can be increased by feeding animals ch…

Vicia brulloi (Fabaceae), a new species from Sicily

2019

Vicia brulloi, a new species from Peloritani range in NE Sicily, is described and illustrated. It is a perennial climbing liane linked to riparian woods, showing close relationship mainly with V. pisiformis, having a scattered European distribution. In particular, V. brulloi is a very rare and extremely localized species morphologically well distinct from V. pisiformis in several remarkable features, such as the dense indumentum covering the vegetative structures and calyces, the shape and size of flower pieces, pods, seeds, as well as seed testa micromorphology. Another relevant peculiarity of V. brulloi is the lower tooth of the calyx replaced by a green leafy appendix, character infreque…

Determination of pigments in vegetables

2004

Plant pigments are responsible for the shining color of plant tissues. They are also found in animal tissues and, eventually in transformed food products as additives. These pigments have an important impact on the commercial value of products, because the colors establish the first contact with the consumer. In addition plant pigments may have an influence on the health of the consumers. Pigments are labile: they can be easily altered, and even destroyed. Analytical processes have been developed to determine pigment composition. The aim of this paper is to provide a brief overview of these methods.

The management of crop-livestock systems at a territory level: the example of grain legume crops and of monogastric livestock in Burgundy, France

2012

Although cereals and oil seed crops are very developed in Burgundy, the area of grain legumes cultivation is small. Concerning monogastric livestock, the region is characterised by a medium size poultry production focussed on markets under quality and origin signs (SIQO) and a relatively small pig production. Although a tendency of co-location of these productions can be observed (at territory and farm scales) and some animals consume locally-produced proteins, there is no strong functional link between these crops and animal activities. This situation is confirmed by the fact that a significant proportion of produced grain legumes are exported by Burgundy, while large quantities of soybean…

L'accumulation des protéines dans les graines de légumineuses

2017

The agroecological benefits of legumes and the renewed interest in the consumption of vegetable proteins stimulate researches on cognitive and applied aspects of seed biology aiming at optimizing protein composition of legume seeds. This article presents the state of knowledge on the genetic and environmental control of the accumulation of major proteins found in legume seeds, with a view to developing varieties with improved nutritional seed quality. It also shows how high-throughput genomics and post-genomics data, along with translational research aiming at transferring knowledge between model and crop species, can accelerate the identification of genes controlling the accumulation of st…

Policy mixes for more vital legume value chains: Evaluation across competing policy frames

2021

Legumes receive increasing attention in sustainability transition research as they can contribute to more sustainable food systems. Previous research has established the need for policies relating to both production and consumption to tackle the marginalisation of legumes in European cropping systems and diets. In this paper, we apply the policy mix framework to food system transition and develop it further into an interpretive policy mix framework to evaluate policy mixes for more vital legume value chains. The interpretive policy mix framework facilitates a better understanding of competing policy frames in designing more consistent, coherent, and comprehensive policy mixes for transition…

2000-2009 Publication metrics reveal world trends of grain legume research

2012

Identifiant ProdInra 271566 BAP SAR CICAP GEAPSI pas de classement CT scientifiqueIdentifiant ProdInra 271566BAPSAR CICAPGEAPSIpas de classement CT scientifique; Grain legumes grown in Europe produce protein-rich seeds of good nutritional value. They can partially replace imported soybean amounting to about 35 Mt in 2010. Legumes also fix N2 naturally with the help of rhizobiaceae bacteria, resulting in fossil energy saving and reduction of glasshouse gas emissions risks. Strength and weaknesses of grain legume research in Europe and other nations are not well known. Therefore we studied 2000-2009 worldwide publications on grain legumes using the CAB database. We built a world corpus of 161…

Breeding annual legumes for sustainable agricultures must target for new and more complex variety ideotypes

2013

International audience; Although yield and total biomass produced by annual legumes remain major objectives for breeders, environment-friendly, resource use efficient including symbiotic performance, resilient production in the context of climate change, adaptation to sustainable cropping systems (reducing leaching and glasshouse gas emissions), adaptation to diverse uses (seeds for feeds foods, non-food, forage or green manures), and finally new ecological services such as pollinator protection, imply the development of innovative genotypes, definition of new ideotypes and acceptance of their commercialisation. Taken as a whole, this means more complex and integrated objectives for breeder…
