A novel method for detection of lipid oxidation in edible oil
The objective of this study was to develop a simple method for detecting lipid oxidation through the color change of a composite film. Schiff's reagent which can form color compound with lipid oxidation products—aldehydes was incorporated into polyvinyl alcohol (PVA) to form the composite film. The effects of PVA molecular weight (Mw), Schiff's reagent/PVA ratio and glycerol content on the response of the composite film to aldehyde were investigated. Sunflower seed oil with various extent of oxidation was used to evaluate the effectiveness of the composite film for lipid oxidation detection. The results showed that the c...

Quality of muffins enriched with upcycled defatted sunflower seed flour
Publication date: Available online 30 November 2019Source: LWTAuthor(s): Simona Grasso, Shuyi Liu, Lisa MethvenAbstractThere is an increased interest and need to valorise food industry by-products by reincorporating them into the food chain. Defatted sunflower seed flour (DSSF), obtained from a by-product of the sunflower industry, has an attractive nutritional profile. The aim of this study was to evaluate the effects of incorporating DSSF at 15% and 30% in muffins as replacement for wheat flour. Proximate composition, physical analyses and sensory quality through Quantitative Descriptive Analysis (QDA) were explored and ...

Identification of rancidity markers in roasted sunflower seeds produced from raw materials stored for different periods of time
Publication date: Available online 8 October 2019Source: LWTAuthor(s): Meng Fu, Xu Shen, Hui Peng, Qiang Zhou, Jing Yun, Yue Sun, Chi-Tang Ho, Huimei Cai, Ruyan HouAbstractRoasted sunflower seeds contain high levels of unsaturated fatty acids, which are susceptible to oxidative rancidity when they are stored under inappropriate conditions. This lipid oxidation affects the quality of roasted sunflower seeds. Rancidity components (mainly including 11 aldehydes, 1 alcohol, 2 ketones, 1 acid and 1 furan) were identified in roasted sunflower seeds using HS-GC-MS-O (headspace-gas chromatography-mass spectrometry-olfactometry).

Tamoxifen induction of Cre recombinase does not cause long-lasting or sexually divergent responses in the CNS epigenome or transcriptome: implications for the design of aging studies
AbstractThe systemic delivery of tamoxifen (Tam) to activate inducible CreERT2-loxP transgenic mouse systems is now widely used in neuroscience studies. This critical technological advancement allows temporal control of DNA-cre recombination, avoidance of embryonically lethal phenotypes, and minimization of residual cell labeling encountered in constitutively active drivers. Despite its advantages, the use of Tam has the potential to cause long-lasting, uncharacterized side effects on the transcriptome and epigenome in the CNS, given its mixed estrogen receptor (ER) agonist/antagonist actions. With the welcome focus on inc...

Docosahexaenoic acid varies in rat skeletal muscle membranes according to fibre type and provision of dietary fish oil
ConclusionThe exquisite responsiveness of all skeletal muscles to as little fish oil as the equivalent of 1-2 fish meals per week in a human diet and the selective relationship to fatigable muscle fibre-types supports an integral role for DHA in muscle physiology, and particularly in fatigue resistance of fast-twitch muscles.SummarySkeletal muscle fibres vary according to structural, metabolic and neurological characteristics and ultimately influences contractile function. This study sort to determine if the composition of phospholipid polyunsaturated fatty acids (PUFA), incorporated in their membranes, might also differ a...

Chlorogenic acid attenuates cadmium-induced intestinal injury in Sprague-Dawley rats.
Abstract
Chronic exposure to cadmium (Cd) causes remarkable damage to the liver and gastrointestinal tract. Previous studies have revealed that chlorogenic acid (CGA) could improve the intestinal barrier integrity for weaned rats. Hence, this study sought to investigate the protective effects of CGA from pure reagent and sunflower seed extract (SSE) on growth performance, antioxidant indicators, inflammatory biomarkers and intestinal barrier function in Cd treated rats. A total of 32 Sprague-Dawley female rats with similar weights were randomly allotted to four treatments: control, CdCl2 (6 mg/kg BW), co...

Publication date: Available online 18 July 2019Source: Current Opinion in Food ScienceAuthor(s): Dimitris Karefyllakis, Atze Jan van der Goot, Constantinos V. NikiforidisThe increasing demand for new ingredients with high functionality can be compensated to some extent by an improved utilization of plant derived materials, like proteins. Abundant amounts of proteins exist in plants, however, the current biorefinery strategies are not suitable for their sturdy matrix and complex composition. Milder and simpler processes should be developed in order to avoid chemicals and conditions that either disregard useful ingredients o...
