Fast pyrolysis bio-oils are feasible energy carriers and a potential source of chemicals. Detailed characterization of bio-oils is essential to further develop its potential use. In this study, quantitative 13C nuclear magnetic resonance (13C NMR) combined with comprehensive two-dimensional gas chromatography (GC × GC) was used to characterize fast pyrolysis bio-oils originated from pinewood, w...

TŘINÁCTÝ JIŘÍ, RICHTER MICHAL, KŘÍŽOVÁ LUDMILA. 2016. Comparison of Maize Silagebased Diets for Dairy Cows Containing Extruded Rapeseed Cake or Extruded Full-fat Soybean as Major Protein Sources. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 901–909. The trial was carried out on four Holstein cows with initial milk yield of 27.3 ± 1.7 kg.day−1. Cows were divided...

Rapeseed mustard cake (RMC) can be readily used as a protein supplement in ruminants’ diet due to its availability and being cheaper than common oil cakes. The use of RMC as protein supplement to ruminant diet is constrained due to its higher level of glucosinolates that have variable adverse effect on palatability, intake, nutrient utilization, thyroid hormone status and overall performance of...

Abstract Rapeseed press cake was upcycled as a protein-enriched ingredient through dry fractionation. The fraction contained higher amounts of phytic acid compared to cake, and phytase treatment applied decrease the content from 6.8 0.5%. effect leading release cations also mimicked by extrinsic calcium addition. Both addition significantly improved heat-induced gel properties but had minor on ...

In recent years, questions have been raised on the possible semi-endogenous status of the alleged xenobiotic thyreostatic drug thiouracil; thiouracil has been detected in the urine of various animals (livestock and domesticated) at concentrations between 1 and 10 μg L(-1) and also in human urine. Although several studies suggest Brassicaceae-derived feed as potential origin, no traces of thiour...

OBJECTIVE Despite the great number of substances produced by the skincare industry, very few of them seem to truly have an effect on the skin. Therefore, given the social implications surrounding physical appearance, the search for new bioactive compounds to prevent or attenuate skin ageing and enhance self-image is a priority of current research. In this context, being rich in valuable compoun...

In this study, extraction of soluble proteins from rapeseed cake using different conventional and innovative extraction processes in order to maximize the extraction yield has been investigated. Firstly, various extraction techniques including ultrasound, microwave, and percolation were tested to increase the protein recovery efficiency. Secondly, response surface methodology (RSM) using a cent...
