“…The combined fermentation of RM can not only improve the degree of protein hydrolysis in RM, but also enhance the solubility of proteins [31]. Some authors have used combined microbial fermentation with enzymatic hydrolysis to improve microbial growth and enzymatic activity [22]. In our study, lowering the dosage of the enzyme preparation during pre-hydrolysis decreased the number of cells produced by the tested yeasts.…”

Rapeseed Meal Waste Biomass as a Single-Cell Protein Substrate for Nutritionally-Enhanced Feed Components

et al. 2023

Rapeseed meal (RM) is produced in large quantities as a byproduct of oil extraction from rapeseeds. However, the efficient utilization of RM as animal feed is limited by its low metabolizable energy, poor palatability, and high levels of fiber and anti-nutritional components. Here, we investigate the potential of enriching RM with single-cell protein through fermentation with conventional and unconventional yeasts. The process of simultaneous saccharification and fermentation improved the parameters of the waste biomass, especially the protein content, while reducing the amount of crude fiber and enhancing the biotransformation of isoflavone compounds present in the waste. Fermentation yielded the highest protein gain for the Saccharomyces cerevisiae Ethanol Red strain (ΔN = 2.38%) at a biomass load of 12.5 g and for Scheffersomyces stipitis (ΔN = 2.34%) at an enzyme dose of 0.125 mL/10 g DM. The crude fiber content (CF) was reduced by 2.55–7.18%. The simultaneous saccharification and fermentation (SSF) process resulted in the conversion of isoflavones to forms with fewer adverse effects and a lower estrogenic activity. The results show the potential of using RM as a substrate for making a nutritionally improved feed components.

“…However, because of the presence of anti-nutritional factors, RM is currently not fully used as a feed additive. Glucosinolates, phytic acid, tannin, sinapine, cellulose, and lignin are the main antinutritional factors in RM [22]. Biological methods appear to be the most researched strategy for improving RM quality.…”

“…Canola ( Brassica napus L .) is an important oilseed crop, the meal (CM) that remains after oil extraction is not used in human food or animal feed applications because of the presence of toxic compounds such as glucosinolates, phytates, erucic acid and phenolics (Manamperi et al 2007 ; Li et al 2018b ; Alashi et al 2013 ; Tene Tayo et al 2022 ; Yang et al 2022 ). Therefore, CM is an ideal resource for the replacement of synthetic polymers in developing biobased composite materials that can be applied in packaging applications.…”

The canola oil industry generates significant waste as canola meal (CM) which has limited scope and applications. This study demonstrates the possibility of valorization of CM as a sustainable natural filler in a biodegradable polymer composite of Poly(lactic acid) (PLA). Generally, interfacial bonding between natural fibers and the polymer matrix in the composite is weak and non-uniform. One possible solution is to derivatize natural fibre to introduce interfacial bond strength and compatibility with the PLA polymer matrix. Here, CM was succinylated in a reactive extrusion process using succinic anhydride at 30 wt% to get 14% derivatization with 0.02 g of -COOH density per g of CM. The CM or succinylated CM at 5 and 15 wt% was co-extruded with amorphous PLA to get composite fibers. CM-PLA and succinylated CM-PLA biocomposites were foamed using a mild and green microcellular foaming process, with CO2 as an impregnating agent without any addition of organic solvents. The properties of the foams were analyzed using differential scanning calorimetry (DSC), Dynamic mechanical thermal analysis (DMTA), shrinkage, and imaging. The addition of CM or succinylated CM as a natural filler did not significantly change the glass transition temperature, melting point, percent crystallization, stiffness, and thermal stability of PLA foams. This suggests succinylation (modification) of CM is not a mandatory step for improving interphase compatibility with the amorphous PLA. The new PLA-CM foams can be a good alternative in the packaging industry replacing the existing petroleum-based polymer foams. Graphical Abstract

“…However, the utilization efficiency of RSM in animal diets is limited due to the presence of anti-nutritional factors such as glucosinolates, phytic acid, tannins, fiber, etc. [7,8]. Glucosinolates, the major antinutritional factors, are catalyzed by myrosinase enzyme presented in the rapeseed or animal gastrointestinal tract into isothiocyanate, thiocyanate, and nitrile which disrupt thyroid, liver, and kidney function of animals [7,9].…”

Improvement of the Nutritional Quality of Rapeseed Meal through Solid-State Fermentation with B. subtilis, S. cerevisiae, and B. amyloliquefaciens

In this study, the effect of solid-state fermentation with Bacillus subtilis GYB6, Saccharomyces cerevisiae NJ1, and Bacillus amyloliquefaciens Y8 on the anti-nutritional factors, nutritional components, bioactive compounds, antioxidant activity, functional properties, and structure of rapeseed meal (RSM) were investigated. Results showed that the action of three strains in the fermentation of RSM caused a significant decline in glucosinolates, phytic acid, crude fiber, and tannins by 99.18%, 42.41%, 27.21%, and 34.17%, respectively. The amount of crude protein, amino acids, and peptides of RSM increased significantly after fermentation. The SDS-PAGE results showed that 12S globulin and 2S albumin protein were almost entirely degraded. Fermentation considerably increased the concentration of total phenolics and flavonoids, and activated antioxidant activity and functional properties. Furthermore, the structural variation was observed by scanning electron microscopy and FTIR spectroscopy. Thus, these results indicated that the solid-state fermentation process in this study was a promising approach to enhance both the nutritional value and bioactivity of RSM, which could be used as value-added functional animal food ingredients.
