“…Mustafa and colleagues have studied a simple tail-end dehulling technique in which desolventized meal has its moisture content adjusted to 16%; this meal is then disc-milled and sieved (Mustafa et al, 1996). This method results in a high fibre and a low fibre fraction which account for 60 and 40% respectively of original meal.…”

-The recent success of dehulled sunflower meals on the French market encourages reconsideration of the possibility of applying dehulling techniques to rapeseed. Hulls account for 18−20% of rapeseed mass; they contain mostly fibres (72%, 78% and 99%, respectively of the seeds' NDF, ADF and ADL). Complete removal of these hulls would result in a high (43%) protein meal with enhanced added value. However, the technical feasibility of producing such a meal is impeded by the relatively high oil content of the hull fraction. This article presents a model of mass balance that takes account both of the purity of the "hull" and "kernel" fractions and comparisons of gross margins between conventional processing and dehulling-based processing. The value of dehulled rapeseed meal is assessed against both a range of market scenarios and the composition and price of a selection of alternative feeds. The gross margin differential favours dehulling only in periods where proteins are expensive and oil relatively cheap, as at present. Reducing the oil content of the hulls affects considerably the profitability of dehulling whereas modification of the protein content has only a modest impact. An important unknown is the effect of antinutritional factors on the final price of dehulled meals. Management of the glucosinolates residues through processing might decrease their noxiousness though the information on this is scant. Since this lack of knowledge is an impediment to the implementation of dehulling technology, research and development investments should start by addressing this question. Technical solutions could be developed to recover the oil contained in the hulls. Such solutions include expelling, aqueous extraction or tail-end dehulling after direct extraction of the seeds.Keywords: Rapeseed / dehulling / proteins / oil / processing / high-protein meal / feasibility / gross-margin Résumé -Nouveau regard sur la faisabilité économique et technique du déplliculage des graines de colza dans le contexte actuel. Le succès récent des tourteaux de tournesol décortiqués sur le marché français amène à reconsidérer la possibilité d'appliquer le procédé de dépelliculage aux graines de colza. Les pellicules de colza représentent 18−20 % de la masse des graines et contiennent principalement des fibres (respectivement 72%, 78 % et 99 % des fractions NDF, ADF et ADL des graines). L'élimination complète de ces pellicules pourrait permettre d'obtenir un tourteau à haute teneur en protéines (43 %) présentant une meilleure valeur ajoutée. À l'heure actuelle, la faisabilité technique d'un tel tourteau est compliquée par la présence d'une quantité relativement importante d'huile dans les pellicules. Cet article présente un modèle de bilan matière en tenant compte de la pureté des fractions « pellicules » et « amandes » et aboutissant à des comparaisons de marge brute entre le procédé conventionnel et celui incluant une étape de dépelliculage. La valeur du tourteau de colza dépelliculé est évaluée dans différents contextes de marché en...

“…Tail-end dehulling of canola meal results in two byproducts, each with distinct chemical characteristics and ruminal nutrient degradability (Mustafa et al 1996). The low fiber meal, relative to regular canola meal, was 6.6% high in crude protein (CP) and 9.5 and 30.4% lower in neutral and acid detergent insoluble CP, respectively.…”

“…This resulted in a low and high fiber meal plus the sample of regular canola meal from each replicate. These samples were chemically characterized, with little variation observed in composition among the five replicates of each meal (Mustafa et al 1996). As such, for the purpose of this study the five replicates were composited to obtain a single sample of each meal.…”

. 1997. In situ amino acid disappearance from regular, low and high fiber canola meal. Can. J. Anim. Sci. 77: 533-535. In situ rumen disappearance of low and high fiber canola meal relative to regular canola meal was determined following 12 h of rumen incubation. In situ amino acid disappearance was similar in low and high fiber and regular canola meal except for threonine and glutamate which was lower (P < 0.05) in high fiber canola meal. It was concluded that ruminal disappearance of amino acids was similar across the three meal types.Key words: Tail-end dehulling, canola meal, high fiber canola meal, low fiber canola meal Mustafa, A.

Sci. 77: 533-535. Nous avons déterminé après 12 h d'incubation dans le rumen la digestion apparente in situ de tourteaux de colza canola à haute et à basse teneur en fibres par comparaison à celle d'un tourteau de canola ordinaire. La digestion apparente des acides aminés était la même pour les 3 types de tourteau, sauf celle de la thréonine et du glutamate qui étaient moins fortes (P < 0,05) dans le tourteau riche en fibres. D'une façon générale, la digestion ruminale apparente des acides aminés était donc semblable dans les 3 tourteaux.

BACKGROUND Air classification was used to fractionate canola meal (CM). The effect of combinations of air classification conditions, including rotor speed ranging from 300 to 1200 rpm, air stream rate from 700 to 860 cfpm, and secondary air from 0 to 30%, on particle size and nutritive composition was investigated. Response surface methodology was used to develop response surface equations to estimate these effects. RESULTS Protein concentration increased in almost all the fine fractions. Effects of both secondary air and rotor speed of the air classifier were significant at P ≤ 0.1 and P ≤ 0.01, respectively. Almost all the fine fractions contained more oil. Rotor speed, air stream rate, and their interaction were significant at P ≤ 0.01. Both acid detergent fiber (ADF) and neutral detergent fiber (NDF) were shifted to the coarse fractions during the air classification. The rotor speed was significant for both ADF and NDF at P ≤ 0.01. CONCLUSIONS Protein shifted to the fine fractions. The highest protein concentration in the fine CM fraction was estimated to be 404.2 g kg−1, demonstrating an enhancement of 10.7%. ADF and NDF shifted to the coarse CM fractions and were respectively estimated to be 294.8 and 332 g kg−1, which were increased by 52.7% and 43.7%. Oil shifted to the fine fractions. The highest concentration was predicted to be 59.7 g kg−1, increased by 45.6%. Fine or coarse fraction yields were estimated to be 35–50%, indicating that they are acceptable for an industrial manufacture. © 2019 Society of Chemical Industry
