Abstract
The invention in particular discloses a method for preparing a single-cell protein feed additive by utilizing ginkgo leaf processing wastes. The method comprises the following steps: processing ginkgo leaf to extract the ginkgo leaf extract (GBE), drying the ginkgo leaf residues, grinding into ultra-fine powder, concentrating the outflow liquid waste subjected to macroporous resin adsorption in the ginkgo leaf extract preparation process into the concentrated solution, mixing at the weight ratio of the ginkgo leaf residue powder to the concentrated solution being (2-3) to 1, adding 15 weight percent of compound microbial fermentation agent for performing fermentation cultivation, carrying out Maillard reaction, drying at low temperature, pressing into granules, and packaging, thereby obtaining the single-cell protein feed additive product. According to the scheme in the invention, the technical gap of the domestic single-cell protein feed additive prepared by utilizing the ginkgo leaf processing wastes is filled, novel methods, process and technical routes are provided for recycling the waste residues and liquid waste in the ginkgo leaf processing waste processing production, and the feasibility is provided for industrialized operation.
