Soybean and casein hydrolysates induce grapevine immune responses and resistance against Plasmopara viticola
2014
International audience; Plasmopara viticola, the causal agent of grapevine downy mildew, is one of the most devastating grape pathogen in Europe and North America. Although phytochemicals are used to control pathogen infections, the appearance of resistant strains and the concern for possible adverse effects on environment and human health are increasing the search for alternative strategies. In the present investigation, we successfully tested two protein hydrolysates from soybean (soy) and casein (cas) to trigger grapevine resistance against P. viticola. On Vitis vinifera cv. Marselan plants, the application of soy and cas reduced the infected leaf surface by 76 and 63%, as compared to th…
Marine organisms as source of bioactive molecules applied in restoration projects
2015
Abstract In recent decades research in the conservation and restoration field has provided sustainable alternatives to traditional procedures for cleaning or controlling the microbial colonization of works of art. In the present study, for the first time novel bioactive molecules extracted from marine invertebrate organisms (Anthozoa) were tested instead of chemical compounds for removing protein layers or as a biocide for controlling fungal or bacterial colonization. In particular, Bioactive Molecules with Protease activity (BMP), acting in a temperature range of 4- 30°C, were tested for the hydrolysis of protein layers on laboratory specimens. The cleaning protocol provides a selective pr…
"Pour moi, le goût du soja n'est pas une barrière à la consommation. Et pour vous ?" : Effet de la culture sur les croyances, attitudes et préférence…
2010
Understanding consumers' beliefs, attitudes and sensory preference is the key to a successful development and introduction of a new food. This thesis carried out a series of cross-cultural studies, France vs. Vietnam, on consumers' representation of soy foods and on sensory perception and preference of soy yogurts, a soy derived product recently developed for French market which does not exist on the Vietnamese market. Despite a favourable image of soy in terms of nutrition and health benefices, French participants reported that the barrier to its consumption was the taste of soy. This finding was confirmed by a consumer test in which French participants gave very low hedonic evaluations to…
Sojas pupiņu un smiltsērkšķu ekstraktu saturoša matu kopšanas līdzekļa izstrāde un efektivitātes noteikšana
2018
Sojas pupiņu un smiltsērkšķa ekstraktu saturoša matu kopšanas līdzekļa izstrāde un efektivitātes noteikšana. Ostrovska G., zinātniskā vadītāja vadošā pētniece Dr. chem. Orola L. Maģistra darbs, 51 lappuses, 16 attēli, 6 tabulas, 59 literatūras avoti, 3 pielikumi. Latviešu valodā. Darbā veikta matu kopšanas līdzekļa- matu maskas bāzes izstrāde, kura papildināta ar sojas un smiltsērkšķa ekstraktiem. Sojas ekstrakts ekstrahēts no sojas pupiņam un ar AEŠH/MS metodi, noteikts ekstraktā esošo aminoskābju saturs. Novērtēta matu maskas bāzes un matu masku efektivitāte uz matu virsmas morfoloģiskajām izmaiņām, matu mehāniskajām un mitruma sorbcijas īpašībām.
Direct determination of oleic acid in soybean oil by capacitively coupled contactless conductivity detection capillary electrophoresis in an oil-misc…
2014
Este trabalho teve por objetivo desenvolver um método analítico direto e rápido para a determinação de ácido oleico em óleo de soja por eletroforese capilar com detecção condutométrica sem contato. O eletrólito de corrida empregado foi uma mistura metanol/1-propanol (1:6 v/v) contendo 4 × 10-2 mol L-1 de KOH e 10% (v/v) em etileno glicol. As amostras foram preparadas pela solubilização de 50 g L-1 de óleo de soja e 1,33 × 10-3 de ácido salicílico (padrão interno) no eletrólito de corrida. Os ensaios quantitativos foram realizados adicionando ácido oleico puro às amostras, na faixa entre 0,53 e 2,13 × 10-3 mol L-1. Sob polaridade negativa, os solutos aniônicos deslocaram-se mais rapidamente …
Efecto del consumo de soja en la longevidad de ratones OF1 machos
2013
Encontrar buenos modelos de envejecimiento es un objetivo importante de la Gerontología. La diferencia de género en la longevidad, es decir, el hecho de que las hembras viven alrededor del 10% más que los machos en muchas especies, incluida la especie humana, ofrece una oportunidad única para estudiar los aspectos fundamentales del envejecimiento. En el contexto de la teoría mitocondrial de radicales libres en el envejecimiento, estudios realizados por nuestro grupo de investigación han encontrado que la producción de especies reactivas de oxígeno es aproximadamente el doble en los machos en comparación con las hembras (Borras et al., 2003). Así, dichas diferencias de longevidad entre macho…
Makro- un mikroelementu plūsmas pētījumi tauriņziežu – gumiņbaktēriju simbiotiskajā sistēmā
2020
Darbā tiek veikta sojas un pupu paraugu sagatavošana un analīze. Makro un mikroelementu koncentrācijas noteikšana tika veikta, izmantojot induktīvi saistītas plazmas masspektrometru. Paraugu sagatavošanai izmantoja slapjo mikroviļņu mineralizāciju.
