“…It is well known that the glucosinolates and phenolic acids like sinapic acid are soluble in organic solvents such as ethanol, methanol and acetone (Dabrowski et al, 1984;Mawson et al, 1995). In order to reduce the antinutritional ingredients the oil free meal was ethanolic extract in accordance to the method described in Section 3.1.…”

-The main problem of the aquaculture sector is the provision of suitable and sufficient fish feed, because the most important protein source in aquaculture, the fish meal, is a limited resource. Due to their high nutritional value the rapeseed proteins have great potential as an alternative protein source for the fish nutrition. Therefore, the aim of this work is to develop a manufacturing process of high quality rapeseed protein concentrates, which can replace the limited marine resource. For this purpose, small pilot scale processing procedures were performed to produce a rapeseed protein concentrate (RPC). The meal for protein extraction was prepared by gentle meal processing. Rapeseed protein fractions were prepared by an aqueous extraction procedure. The obtained protein solution is further purified and then dried. The investigated rapeseed protein extraction process provides RPC with high nutritional value and low levels of antinutritional factors. From the nutritional point of view the produced RPC can be compared with the fishmeal. Its amino acid profile reflects the amino acid demands of fish. The obtained RPC was utilized for experimental setups of fish meal replacement in diets for rainbow trout, turbot, common carp and wels catfish. Experimental results from the conducted feeding trials demonstrate an enormous potential of RPC as protein source in aquafeeds. The highest fishmeal replacement level (up to 100%) was observed in the feeding trials with rainbow trout. Therefore, especially in the nutrition of rainbow trout, RPC was identified as an excellent fishmeal alternative.

“…Jensen and others (1995) have reported similar findings that glucosinolates were destroyed by high temperature, thus improving the canola meal flavor and palatability. Application of organic solvents, such as ethanol, methanol, and acetone, is another efficient way to remove glucosinolates from canola meal (Mawson and others 1995). Jensen and others (1990) also reported the use of enzymes, such as pectinase, protease, and hemicellulase, in reducing the glucosinolates content.…”

Canola protein isolate has been suggested as an alternative to other proteins for human food use due to a balanced amino acid profile and potential functional properties such as emulsifying, foaming, and gelling abilities. This is, therefore, a review of the studies on the utilization of canola protein in human food, comprising the extraction processes for protein isolates and fractions, the molecular character of the extracted proteins, as well as their food functional properties. A majority of studies were based on proteins extracted from the meal using alkaline solution, presumably due to its high nitrogen yield, followed by those utilizing salt extraction combined with ultrafiltration. Characteristics of canola and its predecessor rapeseed protein fractions such as nitrogen yield, molecular weight profile, isoelectric point, solubility, and thermal properties have been reported and were found to be largely related to the extraction methods. However, very little research has been carried out on the hydrophobicity and structure profiles of the protein extracts that are highly relevant to a proper understanding of food functional properties. Alkaline extracts were generally not very suitable as functional ingredients and contradictory results about many of the measured properties of canola proteins, especially their emulsification tendencies, have also been documented. Further research into improved extraction methods is recommended, as is a more systematic approach to the measurement of desired food functional properties for valid comparison between studies.

“…Dehulling of seeds and application of high temperatures and organic solvents (e.g. hexane) during oil extraction as well as sieving of meal decrease the content of glucosinolates, phytate, fibre, cellulose, hemicellulose, sinapin and tannins (Fenwick et al 1986;Anderson-Hafermann et al 1993;Mawson et al 1995;Tripathi et al 2000). Extraction processes from meals with methanolammonia or ethanol will increase protein level and effectively remove glucosinolates, phenolic compounds and soluble sugars, such as sucrose and some oligosaccharides (Naczk and Shahidi 1990;Chabanon et al 2007).…”

The potential of rapeseed protein concentrate as fish meal alternative in diets for rainbow trout (initial average weight 37.8 ± 1.4 g) was evaluated. Nine experimental tanks of a freshwater flow-through system were stocked with 12 fish each. Triplicate groups of fish received isonitrogenous (47.9 ± 0.5% CP) and isoenergetic (22.4 ± 0.2 kJ g -1 ) experimental diets with 0, 66 and 100% of fish meal substituted with rapeseed protein concentrate (71.2% CP), thereby providing 0, 29 and 43% of dietary protein. As the amino acid profile of rapeseed protein concentrate was comparable to fish meal, there was no need to supplement experimental diets with synthetic amino acids. At the end of the 84 days of feeding period, fish growth performance, feed intake and feed efficiencies were not compromised, when 100% of fish meal in the control diet was replaced with rapeseed protein concentrate, revealing a SGR of 1.19 or 1.10, a FCR of 1.09 or 1.18 and a feed intake of 78.5 or 74.7 g in fish fed on the control diet or fed the diet devoid of fish meal, respectively. Intestinal morphology did not reveal any histological abnormalities in all dietary groups. Blood parameters including haematocrit and haemoglobin as well as glucose, triglycerides and total protein in the plasma were not different between treatment groups. Thus, the rapeseed protein concentrate tested here has great potential as an alternative to fish meal in rainbow trout diets.
