“…This is probably a consequence of the ethanol pre-treatment as well as the initial relatively low glucosinolate level in the industrial rapeseed meal used in the study (12.69 µmol g -1 ), as previously evaluated by Ivanova et al (2016). Since this industrial rapeseed meal is composed of mixed cultivars, it is difficult to relate the low glucosinolate concentration to a specific variety.…”

“…According to Wanasundara (2011), the fiber fraction and alcohol soluble components (sugars, glucosinolates and some phenolics) may account for a significant amount of rapeseed derived protein products. The content of total phenols in the rapeseed meal used (1.13 ± 0.04%), previously established by Ivanova et al (2016), was 4-fold reduced to 0.25 ± 0.02% (Table 1) by a simple 4-step ethanol treatment of the raw material. While in low quantities phenols are considered beneficial because of their antioxidant capacity, in higher amounts they reduce nutritional and functional properties of proteins (Aider and Barbana, 2011).…”

“…In 2018, worldwide production of RSM and SFM was estimated at 39.2 Mt and 21.0 Mt respectively (http://www.indexmundi.com/agriculture/). They are mostly dedicated to animal feed because of their high protein content with about 38 g/100 g dry matter (DM) and 28 g/100 g DM for RSM and SFM respectively (González-Pérez and Vereijken, 2007;Ivanova et al, 2016;Ugolini et al, 2015). In addition, studies have shown that these raw materials can also serve as a source of protein isolates with bioactive properties, such as Angiotensin-I Converting Enzyme (ACE) inhibitory activities, antioxidant or antithrombotic activities, and bile acid-binding capacities (Aider and Barbana, 2011;Campbell et al, 2016;Ugolini et al, 2015).…”

Sunflower and rapeseed meals are agro-industrial coproducts that contain high amount of phenolics (1-4 % dry matter), mostly as esters of caffeic acid (CA) and sinapic acid (SA), respectively. The enzymatic hydrolysis of the ester bonds enables to recover the corresponding free phenolic acids that are bioactive compounds and platform molecules for various applications in green chemistry. Here we aimed to find the best route for producing free CA and SA by applying various fungal carboxylic ester hydrolases from recombinant Aspergillus niger strains either directly on crude meal or on their phenolic extracts obtained by methanolic extraction. Two types of meals were studied: (i) industrial (commercial) meals (I-meals), produced by a process that includes cooking at 95-100°C and steam desolventizing at 105-107°C, and (ii) non-industrial meals (NI-meals) obtained at pilot-scale with much milder heat treatment, that offer a higher total phenolic content. CA release through hydrolysis of sunflower meal (SFM) was successfully achieved with A. niger type-B feruloyl esterase (AnFaeB) and chlorogenic acid esterase (ChlE). Maximal amount of free CA released was of 54.0 ± 1.1 to 59.8 ± 2.1 µmol/g defatted dry matter (DDM) from I-SFM (94-100% hydrolysis yield) against 42.0 ± 1.1 to 52.3 ± 0.2 µmol/g DDM (59-73% hydrolysis yield) from NI-SFM in which CA release was hampered by a phenolic oxidation side-reaction, seemingly due to meal endogenous polyphenol oxidase activities. AnFaeB and ChlE hydrolysis of phenolic extracts from NI-SFM increased the CA amount obtained to 55.0-68.1 µmol/g DDM (77-95% hydrolysis yield). In all cases, AnFaeB showed broader specificity towards SFM caffeoyl quinic acid isomers than ChlE. In particular, ChlE did not hydrolyze 3-O-caffeoylquinic acid. The maximal amount of free SA released by AnFaeA hydrolysis was 41.3 ± 0.3 µmol/g DDM from NI-SFM (50% hydrolysis yield) and 32.3 ± 0.4 µmol/g DDM from the phenolic extract (64% hydrolysis yield), with AnFaeA also having sinapine transesterification activity that led to the synthesis of 1,2-di-Osinapoyl-β-D-glucose. Finally, of all the substrates tested for enzymatic hydrolysis in our conditions, I-RSM and NI-SFM extract showed the best compromise between initial total phenolic content, hydrolysis yields and amounts of CA/SA released.

“…Though limiting in lysine, CM is an excellent source of sulfur-containing AA (Woyengo et al, 2010;Li et al, 2015;Ivanova et al, 2016). Canola meal has a rather high concentration of methionine, cysteine, and threonine, but low levels of lysine and tryptophan when compared to soybean meal (Newkirk, 2009;Khajali and Slominski, 2012).…”

The objectives of this research were to determine the effects of high inclusion of canola meal (CM) in gestation and lactation diets on lactation performance, milk composition, energy and nutrient digestibility, and gut health in sows and suckling piglet performance. Standardized ileal digestibility (SID) of CP and AA and standardized total tract digestibility (STTD) of P in CM fed to gestating and lactating sows with or without a multi-enzyme complex (MC) was also determined. In Study 1, results showed no differences in sow and litter performance when soybean meal was replaced with increasing levels of CM in lactation diets. However, energy and nutrient digestibilities were reduced with increasing dietary CM inclusion, probably due to increased fiber content. Results indicated that inclusion of up to 30% CM in lactation diet could support satisfactory sow and suckling piglet performance. Results from Study 2 indicated that up to 30% CM could be included in sow diets as a sole protein source from early gestation until weaning without affecting sow and suckling piglet performance, energy and nutrient digestibility, along with an increase in the abundance of beneficial bacteria in the gut. Furthermore, enzyme supplementation improved P digestibility post-farrowing in sows fed CM-containing diets. From
