Rapeseed meal‐glucosinolates and their antinutritional effects Part 1. Rapeseed production and chemistry of glucosinolates

Abstract

This review, which will be presented in seven parts is concerned with the use of rapeseed meal as an animal feeding stuff. The presence of glucosinolates in the meal limits its use due to a number of antinutritional and physiological effects. Whilst not in itself exhaustive, this review updates earlier reviews by reference to recent papers on the above topics. In this first paper the history of the crop and the current production situation are presented and the nature of glucosinolates and methods for their analysis are reviewed in order to facilitate a better appreciation of the problems referred in later sections.

Emerging technologies for the recovery of isothiocyanates, protein and phenolic compounds from rapeseed and rapeseed press-cake: Effect of high voltage electrical discharges

“…In this line, wastes obtained after compression of oils from oilseeds (rapeseed, mustard seed, and canola), are rich in proteins and fibers, thus being a useful product for being used in animal feeding (Mawson, Heaney, Piskula, & Kozlowska, 1993) (Table 1).…”

Rapeseed meal‐glucosinolates and their antinutritional effects Part 4. Goitrogenicity and internal organs abnormalities in animals

“…Glucosinolates and products of their enzymic breakdown are factors which limit the utilization of rapeseed protein [63]. From the review of results of inany works it follows that glucosinolates may deteriorate flavour and palatability of diet [64] as well as growth and performance of animals fed diets with rapeseed inclusion [65].…”

Rapeseed meal‐glucosinolates and their antinutritional effects Part 7. Processing

“…Chemical characteristics of these compounds [33] and complex mechanism of their antinutritional influence on the animal organism were described in the earlier parts of this paper in which the effect of glucosinolates on flavour and palatability [34], animal growth and performance [35], goitrogenicity and internal organs abnormalities in animal [36], animal reproduction [37] and taint in end products [38] were also discussed. The present paper, the last of the series, presents current technological achievements in quality improvement of protein products obtained from rapeseeds especially of low glucosinolate content.…”
