Cyano Compounds and Goitrin in Rapeseed Meal

Canadian Journal of Physiology and Pharmacology, 1972
Raw rapeseed meals of Brassica campestris and cultivar Bronowski were analyzed for cyano compounds and goitrin following autolysis at 37 °C. Urine excreted from 4 to 36 h by rats dosed with the raw or heated meals (dry heat for 15 min at 110 °C) was also examined for these compounds. Unsaturated nitrile level in raw B.

Rapeseed and rapeseed meal as components in diets of laying hens

Archiv für Tierernaehrung, 1996
In an experiment with 405 Hisex white hens rations with 5-20% low glucosinolate rapeseed (RS) or rapeseed meal (RSM) of 00 quality were used. Feed intake, egg production, individual egg weight and live weight gain were reduced in hens fed 5-20% RS and 10-20% RSM.

Rapeseed meal upgrading—pilot scale preparation of rapeseed meal materials with high or low glucosinolate contents

Animal Feed Science and Technology, 1995
Abstract Because of its antinutritional factors, (high glucosinolate) rapeseed meal cannot yet be used extensively as a protein source in animal feed. The purpose of this work was to prepare, from a dehulled rapeseed meal containing 50.6 micromol g−1 of glucosinolates (GSL), different materials for animal feed experiments.

On Rapeseed Meals. Part XXVI. Some Remarks on the Biological Value of Rapeseed Meal Proteins after Silage

Food / Nahrung, 1978
AbstractThe influence of propionic bacteria on the biological value of potato‐rapeseed meal protein ensilage was investigated. The inoculation of the ensilage with Propionibacterium Petersoni T 112 led to the reduction of the content of goitrogenous compounds (isothiocyanates and oxazolidinethiones) and to an increase of the nutritive value (NPU, PER ...

Ultrafiltration of Rapeseed Meal Extracts

1989
Almost all rapeseed grown in the UK is the winter rape variety, which is low in erucic acid but high in glucosinolates. The residue remaining after oil extraction is called rapeseed meal and contains about 40% protein (dwb). Extraction and ultrafiltration were investigated with the aim of producing protein concentrates with desirable functional ...

Production of Low‐Glucosinolate Rapeseed Meals

Fette, Seifen, Anstrichmittel, 1976
AbstractDefatted meals were prepared from conventional rapeseed, B. napus, Diamant, and from two new varieties of rapeseed, B. napus, Erglu and Lesira by the following processes: 1) Successive extraction or countercurrent extraction of myrosinase‐deactivated ground rapeseed with 70% aqueous acetone for the removal of glucosinolates followed by ...

Rapeseed meal tannins and egg taint

Animal Feed Science and Technology, 1981
Abstract The effect of fractions of a high-glucosinolate rapeseed meal (from B. napus) on trimethylamine (TMA) oxidation in laying hens was investigated in vivo and in vitro. When a tannin-rich fraction containing no glucosinolates was given for 14 days, the hens' ability to oxidise a standard dose of 14C-TMA was reduced by 32%.

The tannin content of rapeseed meals

British Poultry Science, 1976
1. The presence of varying amounts of sinapine, a hydroxylated cinnamic acid derivative, in rapeseed meals has been shown to interfere with the usual methods of tannin estimation. 2. When correction was made for such sinapine contribution the corrected tannin levels were from 18 to 45% lower than those previously reported.

Nutritional Value of Processed Rapeseed Meal

1991
Supplementation of iodine at the level of 3.5 ppm reduced weight gain of the rats fed rapeseed oil meal (ROM) diets. Treatment of ROM with ammonia at the level of 2 or 4% tended to increase metabolizable energy value and availability of dry matter, crude protein and crude ash of ROM in the chicken.

Evaluation of protein concentrates prepared from rapeseed meal

Journal of the Science of Food and Agriculture, 1971
AbstractProtein concentrates have been prepared from rapeseed meals by extraction with sodium chloride solution, followed by removal of the seed coat by screen filtration. This method yielded up to 75% of the original meal N in the form of products containing 61–64% protein (Nx 6·25). The products showed a considerably greater content of ash, and lower
