Se-Enriched defatted rapeseed (Se-DRS), a by-product of rapeseed oil production, is high in Se. This study aimed to detect possible changes in Se-metabolism after Se-DRS consumption and to assess its suitability as a Se supplement in monogaster feed. In this experiment, rats were fed three types of diets differing in Se-form: soybean meal, Se-salt and Se-DRS. Potential differences in Se-metabolism were evaluated based on the total Se concentrations along with non-protein Se speciation patterns in the urine and blood serum of the rats...

Plant-associated fungi are infected by viruses at the incidence rates from a few % to over 90%. Multiple viruses often coinfect fungal hosts, and occasionally alter their phenotypes, but most of the infections are asymptomatic. Phenotypic alterations are grouped into two types: harmful or beneficial to the host fungi. Harmful interactions between viruses and hosts include hypovirulence and/or debilitation that are documented in a number of phytopathogenic fungi, exemplified by the chestnut blight, white root rot, and rapeseed rot fungi...

One of the methods for curing obesity is the inclusion of some substances with the antilipase activity in the diet and thus reducing the uptake of fat components from food. The aim of this research is to provide a stabilized form of lipase inhibitor by immobilization of enzyme on the biopolymers from Agaricus bisporus cell walls. The phenolic compounds extracted from the rapeseed were considered as the lipase inhibitor. The activity of the inhibitor was considerably reduced in the gastric juice, as well as at temperatures above 37 °C and during its storage, which determined the suitability of the inhibitor for stabilization on the matrix...

In this study, solid-state fermentation (SSF) was proposed as an alternative approach to obtain optically pure forms of one of the most common aroma compounds, whisky lactone. Filamentous fungi were used for enantioselective hydrolysis of a racemate of trans and cis whisky lactones, utilizing rapeseed cake as a growth medium. Among the tested fungi, Fusarium oxysporum AM13 and Papularia rosea AM17 were chosen for further studies. Various process parameters, including temperature, moisture content of solid media, and substrate concentration were optimized to maximize the efficiency of the kinetic resolution process...

Rapeseed (RS) is an abundant and inexpensive source of energy and AA in diets for monogastrics and a sustainable alternative to soybean meal. It also contains diverse bioactive phytochemicals that could have antinutritional effects at high dose. When the RS-derived feed ingredients (RSF) are used in swine diets, the uptake of these nutrients and phytochemicals is expected to affect the metabolic system. In this study, two groups of young pigs (17.8 ± 2.7 kg initial BW) were equally fed a soybean meal-based control diet and a RSF-based diet, respectively, for 3 wk...

HYPOTHESIS: This study examined the emulsifying properties of mixed surfactant systems of Quillaja saponins and food-grade co-surfactants (Na-caseinate, pea protein, rapeseed lecithin, and egg lecithin). We hypothesized to these mixtures may build mixed adsorption layers and thus enhance emulsion stabilization. EXPERIMENTS: Oil-in-water emulsions (10%, pH 7) were prepared with different concentrations of co-surfactants (0.1-5.0%) alone or mixed with Quillaja saponins (0...

Increasing demand for natural fragrance ingredients and products has led to their global market growth. 2-Phenylethanol (2-PE) is a volatile substance widely used in food and cosmetics manufacturing. It is generally known that yeast can metabolize L-phenylalanine (L-Phe) to produce 2-PE. However, because the product exhibits an inhibitory effect on yeast cells, simple batch cultivation is uneconomic. The aim of this study was to enhance 2-PE productivity using in situ product removal. Here we present a new method of 2-PE production by yeast in a biphasic system with rapeseed oil as the second phase...

The apetalous trait of rapeseed ( Brassica napus , AACC, 2 n = 38) is important for breeding an ideal high-yield rapeseed with superior klendusity to Sclerotinia sclerotiorum . Currently, the molecular mechanism underlying the apetalous trait of rapeseed is unclear. In this study, 14 petal regulators genes were chosen as target genes (TGs), and the expression patterns of the 14 TGs in the AH population, containing 189 recombinant inbred lines derived from a cross between apetalous "APL01" and normal "Holly," were analyzed in two environments using qRT-PCR...

Preventive measures against soil-borne diseases need to be implemented before cultivation because very few countermeasures are available after the development of diseases. Some soils suppress soil-borne diseases despite the presence of a high population density of pathogens. If the suppressiveness of soil against soil-borne diseases may be predicted and diagnosed for crop fields, it may be possible to reduce the labor and cost associated with excessive disinfection practices. We herein evaluated the suppressiveness of soils in fields with the long-term application of organic amendments by examining the growth of pathogenic Fusarium oxysporum co-cultivated with indigenous soil microorganisms on agar plates...

Background: Obesity progressively leads to cardiac failure. Omega-3 polyunsaturated fatty acids (PUFA) have been shown to have cardio-protective effects in numerous pathological situations. It is not known whether rapeseed oil, which contains α-linolenic acid (ALA), has a similar protective effect. Omega-3 PUFAs are sensitive to attack by reactive oxygen species (ROS), and lipid peroxidation products could damage cardiac cells. We thus tested whether dietary refined rapeseed oil (RSO) associated with or without different antioxidants (vitamin E, coenzyme Q10 and canolol) is cardio-protective in a situation of abdominal obesity...

Rapeseed protein isolate (RPI) and dextran conjugates were prepared by traditional and ultrasonic assisted wet-heating. The effects on the grafting degree (GD), structure, functionality, and digestibility of conjugates were studied. Ultrasonic frequency, temperature, and time all significantly affected the GD. Under the optimum conditions (temperature of 90 °C and time of 60 min), compared to traditional wet-heating, ultrasonic treatment at 28 kHz significantly increased the GD by 2.12 times. Compared to RPI, surface hydrophobicities of conjugates were significantly decreased by graft and ultrasonic treatments...
