We analyzed and compared the difference in sinapine concentration in rapeseed meal between the filamentous fungus, Trametes sp 48424, and the yeast, Saccharomyces cerevisiae, in both liquid and solid-state fermentation. During liquid and solid-state fermentation by Trametes sp 48424, the sinapine
Six groups of 10 growing rats each were fed ad libitum for 15 days one of six diets: diet A, rapeseed (3.80 g of sinapine/kg DM); diet B, ethanol/water-extracted rapeseed (0.48 g of sinapine); diet C, control diet; diet G, control diet + 3.74 g of extracted sinapine; diet H, control diet + 3.72 g of
Sinapine is the main secondary metabolite present in rapeseed pomace (RSP) with its concentration being dependent on rapeseed processing, growing conditions, extraction parameters and the country of origin. Here we report, the concentration of sinapine from an extract of defatted RSP harvested in
We developed two mutant populations of oilseed rape (Brassica napus L.) using EMS (ethylmethanesulfonate) as a mutagen. The populations were derived from the spring type line YN01-429 and the winter type cultivar Express 617 encompassing 5,361 and 3,488 M(2) plants, respectively. A high-throughput
Choline and its metabolites have diverse and important functions in many physiological processes, especially for anabolic metabolism in growth and reproduction. Besides endogenous biosynthesis and direct choline supplement, choline esters in the diet are another source of choline in the body.
For the more efficient detoxification of phenolic compounds, a promising avenue would be to develop a multi-enzyme biocatalyst comprising peroxidase, laccase and other oxidases. However, the development of this multi-enzyme biocatalyst is limited by the vulnerability of fungal laccases and
Rapeseeds were treated with microwaves under 800 W for 0, 1, 2, 3, 4, 5, 6, 7, and 8 min at a frequency of 2450 MHz, and oil was extracted with a press to investigate the influence on phenolic compounds, including sinapine, the main free phenolic acids, and canolol content in the rapeseeds and oil
The intake by growing pigs of a diet containing British rapeseed meal (Brsm) extracted once with water was greater than that of a similar diet containing untreated Brsm, and a diet containing Brsm extracted twice with water was eaten more readily than one containing Brsm extracted once with water.
In this study, rapeseed was pretreated by steam explosion pretreatment technology and subsequently pressed to prepare rapeseed oil. GC, UPLC, and HPLC techniques were employed to analyze the quality characteristics of the rapeseed oil, including the canolol content and other quality characteristics.
The feasibility of using untreated rapeseed meal as a nitrogen source for iturin A production by Bacillus subtilis 3-10 in submerged fermentation was first evaluated by comparison with two different commercial nitrogen sources of peptone and ammonium nitrate. A significant promoting effect of
Cold-pressed rapeseed meal with high protein content (38.76% protein dry weight basis) was used to prepare rapeseed protein isolates (RPIs) by alkaline extraction (pH 8.0, 9.0, 10.0, 11.0, 12.0 and 13.0) and acid precipitation (pH 3.0, 3.5, 4.0, 4.5, 5.0 and 5.5). The protein with an intact
A feeding trial with brown laying hens was carried out in order to examine the effects of chemical and hydrothermal treatment of rapeseeds on the performance and thyroid parameters of birds during a long-term experiment. Untreated and treated rapeseeds were included in layer diets at a level of 7.5,
A cation-exchange column packed with CM-Sephadex C25 matrix was evaluated for its efficiency, capacity, elution volume, and reproducibility in purifying crude extracts of rapeseed or meal for the determination of sinapine content. Combined with a single extraction and ion-exchange column
