The physicochemical properties, fatty acids, sterols, tocols, total phenol content and antioxidant activity of ATO seed were examined and compared. The best extraction yield was from SE (21.97 ± 0.01%), followed by MAE (19.28 ± 0.13%) while that of UAE was the lowest (16.5 ± 0.1%). Analysis of the chemical composition of these oils showed that linoleic acid and β-sitosterol were the main fatty acid and sterol compounds, respectively. A large amount of fatty acids and sterols were not significantly affected by the three extraction methods. Nevertheless, the tocols, the total phenols contents and the antioxidant power showed a variation between these three extracted oils. Based on these results, it was found that this specie has great potential for industrial use.","PeriodicalId":19440,"journal":{"name":"OCL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76568713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vilgis","doi":"10.1051/ocl/2023004","DOIUrl":"https://doi.org/10.1051/ocl/2023004","url":null,"abstract":"Oleosomes have emerged in the last decade as a multipurpose oil-in-water emulsion suitable for engineering new lipids materials. The need to increase alternative and sustainable methods to modulate the rheological properties of emulsions has been the leading research interest in the oleogelation field. Soybean oleosomes are evaluated as building blocks for creating oleogels in combination with sodium alginate or ι-carrageenan as the structuring elements. Polymer bridging provides a route to produce compact soft, malleable gels by exploiting attractive electrostatic interactions between negatively charged polysaccharides and oleosome surfaces. We investigated the viscoelastic properties of concentrated polymer bridged gels by oscillatory rheological measurements. The rheological characteristics are governed predominantly by the type of polysaccharide and by the ratio between polysaccharide and oleosome content. One yielding step at low strains indicates the breaking of polysaccharide bridging bonds and was visible in all samples. A two-step yielding process, where the second step corresponds to the cage-breaking process, was present at polysaccharide/oleosome ratios where optimum bridging occurs for alginate and carrageenan, 0.005 g/g, 0.01 g/g, respectively. Nonetheless, the bumps corresponding to the second yielding point were more prominent in alginate gels than in carrageenan gels due to the greater bridging ability of alginate. Identifying these rheological hallmarks could provide new ideas towards the improved design of plant-based fatty food products, e.g., cream cheeses and vegan sausages surrogates.","PeriodicalId":19440,"journal":{"name":"OCL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76056459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its current purpose is to “bring together specialists in the production, processing and use of oils, fats and derivatives in order to promote the acquisition and extension of knowledge in these branches of industry, to establish and maintain friendly relations between the members of the association”. It also aims to award the Chevreul Medal created in 1963 in memory of the creator of fat chemistry who lived and worked for many years in this magnificent place where we are currently the Verniquet amphitheater ofMuséum national d’Histoire naturelle in Paris. It was also in 2011 that SFEL joined 66 rue La Boétie in Paris in the premises of the Fédération Nationale des Industries des Corps Gras (FNCG). From 2011 to date, the following people have been involved in the life of the association: – As Presidents: Philippe GUESNET since 2021, Frédéric FINE (2019–2020), Michel LINDER (2017–2018), Fabrice TURON (2015–2016), Pierre VILLENEUVE (2012–2014) and Anne LE GUILLOU (2009–2012); – As General Secretary: Claire BERTON-CARABIN currently and since 2019, Claire BOURLIEU-LACANAL (2016–2018), Elmira ARAB-TEHRANY (2017), Michel LINDER (2015–2016), Anne LEGUILLOU (2013–2014), and Jean-Claude ICART (2008–2012); – As Treasurer: Bernadette DELPLANQUE (2019–2023) linchpin of the current Chevreul days with Philippe GUESNET (2017–2018), and Alain RANCUREL (2003–2016) true memory of our association. All in all, a happy collaboration of researchers, academics, teachers, business executives, technical and interprofessional centers in the lipids and fats sector. The highlight of this period 2011–2023 was undoubtedly the 2017 Congress of Nancy “Lipids & Brain, Lipids in Alzheimer disease” organized by the team of Michel LINDER of the University of Lorraine on a theme of great scientific and practical interest, with a public conference given by Stephan CUNNANE Chevreul Medalist 2017 in the sumptuous and prestigious setting of the major salons of the City Hall of Nancy overlooking Place Stanislas.

Fermented Acetes shrimp (called cincalok) is a traditional side dish from Indonesia rich in astaxanthin. This study extracted astaxanthin from cincalok using the glass beads vortex method with virgin coconut oil (VCO) as a green solvent. Several parameters that affect the amount of astaxanthin extracted, such as the ratio between sample and solvent, contact time, and particle size of glass beads, have been tested. The physicochemical characteristics of VCO before and after extraction were also analyzed. The UV-Vis spectrophotometer analysis results showed that the optimum ratio between sample and solvent was 1:10 g/mL, the optimum contact time was 15 minutes, and the optimum particle size of the glass beads was 60–80 mesh. Under these optimum conditions, the amount of astaxanthin extracted was 27.97 μg/g dry weight of cincalok or 2.79 μg/mL VCO. After extraction, the viscosity and density of VCO still meet the Indonesian National Standard with values of 17.98 mm2/s and 917.2 kg/m3, respectively. Before and after extraction, the GC-MS chromatogram shows the main component of fatty acids in VCO is lauric acid, with a percentage of 27.28 and 26.72%, respectively.

A two-year field experiment was conducted at Tehran, Iran, in a split plot design and replicated thrice to examine the effect of the planting density (low, moderate and high) on ten cotton genotypes. In term of lint yield and among the cotton genotypes G8 (1269 kg · ha−1), G4 (1263 kg · ha−1), G1 (1239 kg · ha−1) and G2 (1123 kg · ha−1) were statistically at par with each other but significantly superior to G7 (914 kg · ha−1) and G9 (936 kg · ha−1). Lint yield in high plant density (1386 kg · ha−1) was found to be remarkably superior over medium and low plant density (1029 and 890 kg · ha−1, respectively) by average of 25.7% and 35.7%, respectively. Cotton genotypes at low plant density had higher boll plant−1 (6.46% and 15.3%, respectively), lint percentage (5.8% and 12%, respectively) and lint strength (0.6% and 1.9%, respectively) compared to moderate and high plant densities. The genotypes cultivated at high plant density produced higher seed and lint yield, higher lint elasticity and lower seed oil content, lint length and lint quality index. Based on this experiment, it is concluded that high seed cotton yield can be achieved at high plant density while higher lint quality can be yielded at low plant density.","PeriodicalId":19440,"journal":{"name":"OCL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86903799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic diversity and selection of valuable crossing parents are the key to successful breeding and improvement of this crop. In this regard, genetic variation within the existing germplasm must be explored and characterized. Therefore, the present study was carried out to investigate the genetic diversity among 22 varieties from Morocco as well as other origins, using twenty ISSR primers. The selected primers have generated a total of 319 markers. Polymorphic amplified bands varied from 8 to18, with an average of 13 per primer. The diversity index (PIC value) ranged from 0.295 to 0.509, with a mean value of 0.37 per primer, indicating a good genetic diversity level for the primers used. The average similarity coefficient was 0.31, fluctuating between 0.176 and 0.456, and the pairwise comparison of the studied varieties showed a great discriminating power of primers and a large genetic diversity among accessions. A total of eight ISSR primers could be identified as key to rapeseed varietal determination. Hierarchical classification allowed identifying three groups with some phylogeographic structuring. This is the first report of molecular characterization of rapeseed germplasm in Morocco and Africa. The obtained results have important implications for management of this germplasm to conserve the existing genetic diversity and use it properly in breeding programs in Morocco as well as in other Mediterranean and African countries.","PeriodicalId":19440,"journal":{"name":"OCL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80068645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current research was conducted to identify potential agroecology and rate of NP (nitrogen and phosphorous) fertilizer for the high yield production of camelina crop. Two major agroecological zones, namely highland (moist dega) and midland (moist weyna-dega) agroecologies, were tested. The experiments in both agroecology were conducted in RCBD design with similar treatments. The treatments were (T1 = 0 kg N ha−1, 0 kg P ha−1), (T2 = 30 kg N ha−1, 10 kg P ha−1), (T3 = 60 kg N ha−1, 20 kg P ha−1), (T4 = 90 kg N ha−1, 30 kg P ha−1), (T5 = 120 kg N ha−1, 40 kg P ha−1) and (T6 = 150 kg N ha−1, 50 kg P ha−1). Significant (P < 0.05) differences were observed among the fertilizer treatments. Accordingly, in highland, the highest seed weight (8.37 g plant−1) and grain yield (1814.54 kg ha−1) were recorded from T5, while in midland, the highest seed weight (3.89 g plant−1) and grain yield (843.97 kg ha−1) were recorded from T6. The highest aboveground biomass (32.08, 18.49 g plant−1) and plant height (102.34, 86.33 cm) were recorded from T6 in highland and midland agroecology, respectively. According to the Pearson’s correlation analysis, significant (P < 0.001) positive correlation was observed between the plant height, seed weight, aboveground biomass and grain yield.

A split-plot design, with two varieties as the main plot and four sowing times as the subplot, was carried out over two growing seasons (2017–2019) in Samsun, Turkey. Sequential path analysis revealed that, as first-order predictors, grain yield and oil content displayed the most significant and positive direct effects on oil yield in both summer and winter cultivation. The sequential path analysis of second-order variables over the first-order variable revealed that seed number per pod and pod number explained approximately 90% of the variation of the grain yield in summer cultivation and branch number explained approximately 67% of the variation grain yield in winter cultivation. These results indicated that grain yield, as a main predictor of oil yield, had different pathways to affect oil yield in the summer and winter seasons. A higher magnitude of seed number per pod compared to pod number in this study indicated that selecting for higher grain yield can be done indirectly using plants with lower pod number and higher seed number per pod in the summer season. Moreover, branch number was the only trait that had a direct negative effect on grain yield in the winter season, indicating that plants with lower branch number should be selected for higher grain yield. Different environmental factors, including the seasonal cultivation of camelina in this study, were found to be a key factor in improving oil yield and, hence, should be considered as criteria indices in camelina breeding programs in the future.","PeriodicalId":19440,"journal":{"name":"OCL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89767400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
