This invention discloses a method for preparing high-transparency tamarind polysaccharide gum through decolorization and deodorization. A combined purification process of enzymatic hydrolysis-sedimentation-chemical degradation-solvent washing-ultrafiltration is employed. Enzymatic hydrolysis degrades large molecules of proteins and fats in the extract into smaller molecules. Sodium hypochlorite is used for chemical degradation, oxidizing aldehydes and ketones in the extract into carboxylic acids. Finally, organic solvent washing and ultrafiltration purification remove impurities generated during enzymatic hydrolysis and chemical degradation, ultimately yielding high-transparency, odorless tamarind polysaccharide gum. The final product is white, with a transmittance of up to 95.4% at a 1% concentration, and is completely odorless, significantly improving product quality. This preparation process is simple, operates under mild conditions, and is suitable for industrial production.

This application relates to the interdisciplinary fields of digital marketing and electronic information technology, and specifically to a method for intelligent demand mining and precision marketing for small and medium-sized enterprises (SMEs) in the electronic information industry. The method includes: generating anonymized simulated customer data for SMEs in the electronic information industry, with the customer data generated based on customer characteristics in the electronic information industry, including customer attribute information and demand expression information; constructing a mapping model between customer attributes and product characteristics based on the customer data; analyzing the customer data based on the mapping model to mine potential customer needs and quantify the intensity of those needs; and generating marketing solutions adapted to the electronic information industry scenario based on these potential needs. This solves the problems of difficulty in demand mining, extensive marketing methods, and lack of digital marketing capabilities among SMEs in the electronic information industry. While ensuring data compliance, it lowers the technical application threshold and achieves accurate demand identification, automatic generation of marketing solutions, and continuous model evolution.

This invention discloses a method for rapidly adjusting the furnace conditions of a lean-burn electric arc furnace, belonging to the field of pyrometallurgical nickel smelting technology. The method includes: measuring the height of the frozen layer inside the lean-burn electric arc furnace; when the frozen layer height is greater than 650 mm, simultaneously implementing coordinated control operations to reduce the slag oxidation depth (making the converter slag magnetic iron content <25%) and increase the reducing agent addition rate of the lean-burn electric arc furnace; after adjustment, measuring again, if the frozen layer height is less than 600 mm, restoring to normal process parameters; otherwise, repeating the adjustment until the target is met. This invention establishes a rapid response and upstream-downstream coordination mechanism based on the frozen layer as a criterion, which can effectively reduce the magnetic iron content in the slag, quickly eliminate excessively thick frozen layers, significantly improve slag fluidity, and ensure the stable and efficient operation of the lean-burn electric arc furnace system.
