Combined Thermomechanical–Biological Treatment for Corn By-Product Valorization into Added-Value Food (Feed) Material
The aim of this study was to apply the combined thermomechanical–biological treatment for corn processing by-product (CPBP) valorization to added-value food and feed material. The mechanical–thermal pre-treatment was performed by applying the extrusion technique. Extruded CPBPs (14, 16, and 18% mois...

| description | The aim of this study was to apply the combined thermomechanical–biological treatment for corn processing by-product (CPBP) valorization to added-value food and feed material. The mechanical–thermal pre-treatment was performed by applying the extrusion technique. Extruded CPBPs (14, 16, and 18% moisture) were further biodegraded with <i>Lactiplantibacillus plantarum-LUHS122</i> (Lpl), <i>Liquorilactobacillus uvarum-LUHS245</i> (Lu), <i>Lacticaseibacillus casei-LUHS210</i> (Lc), and <i>Lacticaseibacillus paracasei-LUHS244</i> (Lpa). Acidity parameters, microbial characteristics, sugars concentration, amino and fatty acids profile, biogenic amines (BA), and antibacterial and antifungal properties of CPBP were analyzed. Fermented CPBP had a reduced count of mould/yeast. A significantly lower (<i>p</i> ≤ 0.05) count of total enterobacteria was found in most of the extruded–fermented CPBP. Fermentation of extruded CPBP (moisture of 16 and 18%) increased valine and methionine content. Cadaverine and spermidine were not found after treatment of CPBP, and the lowest content of BA was found in the extruded–fermented (Lpa, moisture 18%) CPBP. Applied treatment had a significant effect on most of the fatty acids. CPBP fermented with Lpl, Lu, and Lpa displayed inhibition properties against 3 of the 10 tested pathogenic/opportunistic bacterial strains. Extruded–fermented (Lu, Lc, and Lpa moisture of 14 and 18%) CPBP showed antifungal activity against <i>Rhizopus.</i> Extruded–fermented (14% moisture, Lpl) CPBP inhibited <i>Rhizopus</i> and <i>Aspergillus fumigatus</i>. In conclusion, combined treatment can improve certain parameters and properties of CPBP in order to produce safer and more nutritious ingredients for food and feed industries. |
