Genetics and Consequences of Crop Domestication

14-06-2013 | Sherry A. Flint-Garcia, Journal of Agricultural and Food Chemistry, 2013

Phenotypic variation has been manipulated by humans during crop domestication, which occurred primarily between 3000 and 10000 years ago in the various centers of origin around the world. The process of domestication has profound consequences on crops, where the domesticate has moderately ...

Enhanced Dispersibility and Bioactivity of Curcumin by Encapsulation in Casein Nanocapsules

14-06-2013 | Kang Pan; Qixin Zhong; Seung Joon Baek, Journal of Agricultural and Food Chemistry, 2013

In this work, a novel encapsulation method was studied by spray-drying a warm aqueous ethanol solution with codissolved sodium caseinate (NaCas) and lipophilic food components, using curcumin as a model compound. The encapsulation caused the loss of crystallinity of curcumin. After hydration ...

Phenolic Profiles of Vitis davidii and Vitis quinquangularis Species Native to China

14-06-2013 | Na-Na Liang; Qiu-Hong Pan; Fei He; Jun Wang; Malcolm J. Reeves; Chang-Qing Duan, Journal of Agricultural and Food Chemistry, 2013

The accumulation of phenolics in the skins of two Vitis davidii cultivars (‘Ziqiu’ and ‘Xiangzhenzhu’) and one Vitis quinquangularis cultivar (‘Xiangshan No. 4’) native to China was followed during ripening. It was found that the anthocyanin composition of all three grapes was dominated by ...

Influence of Phenols Mass Fraction in Olive (Olea europaea L.) Paste on Volatile Compounds in Buža Cultivar Virgin Olive Oil

13-06-2013 | Valerija Majetić Germek; Olivera Koprivnjak; Bojan Butinar; Lorena Pizzale; Milena Bučar-Miklavčič; Lanfranco S. Conte, Journal of Agricultural and Food Chemistry, 2013

The influence of the phenolic content in olive paste of cv. Buža increased by the addition of an aqueous solution of phenolic extract of freeze-dried olive pulp (cv. Istarska bjelica) on the final products of the lipoxygenase pathway in oil was studied. Increases by 12, 38, and 56% for ripe ...

Evaluation of the Impact of Dietary Petroselinic Acid on the Growth Performance, Fatty Acid Composition, and Efficacy of Long Chain-Polyunsaturated Fatty Acid Biosynthesis of Farmed Nile Tilapia

13-06-2013 | Chaiw-Yee Teoh; Wing-Keong Ng, Journal of Agricultural and Food Chemistry, 2013

The present study aimed to investigate the potential role of dietary petroselinic acid (PSA) in enhancing the n-3 long-chain polyunsaturated fatty acid (LC-PUFA) content in fish tissues. Three isolipidic casein-based diets were formulated to comprise graded levels of PSA (0, 10, or 20% of ...

Cyclic Acyloxonium Ions as Diagnostic Aids in the Characterization of Chloropropanol Esters under Electron Impact (EI), Electrospray Ionization (ESI), and Atmospheric Pressure Chemical Ionization (APCI) Conditions

13-06-2013 | Anja K. K. Rahn; Varoujan A. Yaylayan, Journal of Agricultural and Food Chemistry, 2013

During mass spectrometric analysis of various lipids and lipid derivatives such as the chlorinated counterparts of triacylglycerols, the detailed structure of the characteristic and common ions formed under electron impact (EI), electrospray ionization (ESI), and atmospheric pressure chemical ...

Development and Validation of Methods for the Extraction of Phenolic Acids from Plasma, Urine, and Liver and Analysis by UPLC-MS

13-06-2013 | Daniela M. de Oliveira; Carolina B. Pinto; Geni R. Sampaio; Lina Yonekura; Rodrigo R. Catharino; Deborah H. M. Bastos, Journal of Agricultural and Food Chemistry, 2013

This study developed and validated a method for the extraction and determination of 11 phenolic acids in rat plasma, urine, and liver by ultraperformance liquid chromatography–mass spectrometry (UPLC-MS). A system suitability test (instrumental linearity, area, and retention time precision) ...

Stilbenes and Anthocyanins Reduce Stress Signaling in BV-2 Mouse Microglia

13-06-2013 | Amanda N. Carey; Derek R. Fisher; Agnes M. Rimando; Stacey M. Gomes; Donna F. Bielinski; Barbara Shukitt-Hale, Journal of Agricultural and Food Chemistry, 2013

Blueberries contain an array of phytochemicals that may decrease both inflammatory and oxidative stress. This study determined if pterostilbene, resveratrol, and two anthocyanins commonly found in blueberries, delphinidin-3-O-glucoside and malvidin-3-O-glucoside, would be efficacious in ...

Monascin and AITC Attenuate Methylglyoxal-Induced PPARγ Phosphorylation and Degradation through Inhibition of the Oxidative Stress/PKC Pathway Depending on Nrf2 Activation

13-06-2013 | Wei-Hsuan Hsu; Bao-Hong Lee; Chih-Heng Li; Ya-Wen Hsu; Tzu-Ming Pan, Journal of Agricultural and Food Chemistry, 2013

Abnormal cellular accumulation of the dicarbonyl metabolite methylglyoxal (MG) results in cell damage, inflammation, and oxidative stress. It is also associated with increased protein linkage to form advanced glycation end products (AGEs) or induce DNA strand breaks. The association between ...
