This invention belongs to the field of food processing technology, specifically relating to a fermented frozen dough food composition and its application, as well as fermented frozen dough. This invention utilizes flour with a wet gluten content of 20-24 wt% and an extensibility of 140-160 mm at 45 minutes, while controlling the pre-proofing process to ensure the volume after proofing is 1.4-1.6 times the volume before proofing. This improves the quality of fermented frozen dough foods without the use of quality improvers, solving problems such as shrinkage, collapse, wrinkling, stickiness, and lack of softness in traditional Chinese fermented frozen dough foods that require thawing and proofing. The resulting frozen dough products can be directly heated without thawing and proofing, exhibiting no shrinkage or collapse after heating, a smooth surface, and high scores in appearance and taste. This technology, which eliminates the need for improvers, is safer and has higher market acceptance. It is suitable for producing frozen steamed buns, dumplings, twisted rolls, and leavened pancakes, among other traditional Chinese fermented dough foods, and has a wide range of applications and high market value.

This invention discloses a negative carbon lightweight aggregate based on CO2 mineralization of coal-based solid waste and its preparation method, belonging to the technical field of solid waste resource utilization and low-carbon building materials. The method uses coal-based solid waste such as fly ash and coal slag as main raw materials, introducing uniform micropores through spray granulation with a trace amount of hydrogen peroxide solution. After pre-curing and drying, it is then mineralized and solidified using a low-concentration CO2 atmosphere. This method eliminates the need for cement or other cementing materials, resulting in low cost and no indirect carbon emissions. Furthermore, by synergistically controlling the hydrogen peroxide foaming and CO2 mineralization enhancement processes, the bulk density of the aggregate is significantly reduced; the resulting aggregate has a low bulk density (630~860 kg / m³). 3 With a compressive strength of 4.1~6.0MPa and a water absorption rate of 14~20%, it can meet the requirements of super high-rise buildings, large-span structures, prefabricated components, and the reinforcement and renovation of old buildings, significantly increasing the applicability and economy of coal-based solid waste lightweight building aggregate.

This invention provides a chitosan-based edible film with a nano-network structure, its preparation method, and its application. The preparation method includes the following steps: 1) Adding zein to water, adjusting the pH, and then adding a phosphorylation reagent to obtain a mixed solution. After dialysis, centrifugation is performed, and the supernatant is freeze-dried to obtain phosphorylated zein nanoparticles; 2) Adding microcrystalline cellulose to FeCl3·6H2O solution, heating in a water bath, vacuum filtering, washing the precipitate until white, and freeze-drying the obtained precipitate to obtain cellulose nanocrystals; 3) Preparing a coating solution: Adding the phosphorylated zein nanoparticles and cellulose nanocrystals to a chitosan hydrochloride solution to obtain a coating solution; 4) Adding a plasticizer to the coating solution, ultrasonically degassing, and then pouring the mixture onto an acrylic plate to naturally form a film, thus obtaining an edible film. The chitosan-based edible film prepared by this invention can be used to reduce cherry cracking when exposed to rain. It is safe and non-toxic and has high market value.

This invention discloses a clear, stable, and low-irritant plant-based compound beverage, its preparation method, and its application. The beverage is formed by the in-situ self-assembly of polyphenol-containing plant extracts and small-molecule food-derived oligopeptides in an aqueous solution, creating nano-complex particles with an average particle size of 80–200 nm, a Zeta potential of -25 to -40 mV, and a PDI ≤ 0.3. It contains no added exogenous stabilizers, thickeners, flavoring agents, fragrances, or colorings. After 30 days of accelerated clarification at 37°C, no precipitation occurs, with a turbidity ≤ 5 NTU and a light transmittance ≥ 90%, effectively masking bitter and spicy irritations. The plant extracts are a compound of kudzu root, Japanese raisin tree fruit, chrysanthemum, poria cocos, monk fruit, ginger, and yam, with a polyphenol to oligopeptide mass ratio of 3:4. The product can relieve dry mouth and throat discomfort caused by alcohol consumption, staying up late, and smoking. The process is simple and suitable for industrial production.

This invention discloses a highly accurate Chinese spelling checking method, system, and medium. The method includes the following steps: acquiring a corpus to be used, configuring a replacement table to be used, and generating near-phonetic error samples and near-shape error samples to be used based on the corpus; training a decision model to be used based on the corpus, and training a checking model to be used based on the near-phonetic and near-shape error samples; and performing text checking and error correction operations on the acquired text to be checked based on the replacement table, the trained decision model, and the checking model. This invention can efficiently generate high-quality and highly realistic training samples, and can detect errors in Chinese text by independently setting the trained error detection model and post-processing decision model, and perform high-quality error correction judgment after error detection, further reducing the model's error correction rate and improving the correction quality, thus opening up a new method for Chinese spelling error detection.
