Protéines d'origine unicellulaire de champignons/fungi

What it is. Single-cell protein produced by fermentation of Aspergillus oryzae, Paecilomyces varioti or Trichoderma viride on substrates mainly of plant origin (molasses, sugar syrup, alcohol, distillery residues, cereals and starchy products, fruit juice, whey, lactic acid, sugar, hydrolysed plant fibres) with fermentation nutrients such as ammonia or mineral salts. The product is characterised by its crude protein and crude ash content.

What it is for. This type of ingredient is generally used as a protein source in compound feed, supplying crude protein of microbial origin. It would typically be considered for various species and physiological stages, as an alternative or complementary protein source depending on formulation needs. Use is adjusted according to the protein and ash levels declared for the specific batch.

Points to watch. Crude protein, crude ash and propionic acid (if above 0.5%) must be declared. Composition can vary depending on the fermentation substrate and strain used, which should be checked batch by batch; no maximum inclusion level is specified in the official description.
