The invention discloses a vegetable protein fermentation production process, belongs to the field of vegetable protein deep processing, and aims to solve the problems of low protein hydrolysis degree, low small molecule peptide content, low survival number of probiotics and poor product stability of a traditional vegetable protein fermentation process. The process comprises the following steps: raw material pretreatment: performing ultrasonic-assisted crushing to prepare a suspension and adjusting the pH value; ultrasonic-assisted enzymolysis: adding a compound enzyme preparation and carrying out ultrasonic treatment; enzyme deactivation; fermentation strain preparation: culturing aspergillus oryzae, lactobacillus plantarum and streptococcus thermophilus composite strains; performing segmented temperature-controlled fermentation: performing fermentation at 28-30 DEG C for 12-16 hours, and then performing fermentation at 33-35 DEG C for 8-12 hours; and post-processing. Through the synergistic effect of ultrasonic-assisted crushing, ultrasonic-assisted enzymolysis and segmented temperature-controlled fermentation, the protein hydrolysis degree is larger than or equal to 45%, the proportion of small molecule peptide is higher than 25%, the survival number of probiotics is larger than or equal to 1 * 10 < 6 > CFU / g, the nutritive value and fermentation efficiency of the product are remarkably improved, and the process is stable and easy to industrialize.

The invention relates to the technical field of compound fertilizers, and provides a high-temperature-resistant bacteria-containing compound fertilizer and a preparation method thereof.The preparation method comprises the following steps that nanoscale freeze-dried bacterial powder is prepared from bacillus, bacillus stearothermophilus and rhodopseudomonas palustris; mixing the nano TiO2 modified SiO2 composite aerogel, diatomite, the modified charcoal, sepiolite and pullulan to prepare a microbial inoculum protection composite carrier; and mixing the freeze-dried bacterial powder with a carrier, and drying to obtain the micron-sized capsule bacterial agent. Uniformly mixing a reinforcing agent, a plasticizer and a stabilizer to prepare a performance regulator; the preparation method comprises the following steps: melting choline chloride-containing urea and monoammonium phosphate to prepare molten slurry; mixing the molten slurry with a compound fertilizer to form uniform slurry; and mixing the slurry with a micron-sized capsule microbial inoculum and a performance regulator, and granulating to obtain the high-temperature-resistant bacterium-containing compound fertilizer. By optimizing the adaptability of a microbial agent embedding carrier and a melting system, the technical bottleneck of conflict between high-temperature inactivation of the microbial agent and physical properties of a product is solved.
