Fermentation technology of low-salt fermented bean curd
The invention provides a fermentation technology of low-salt fermented bean curd. The fermentation technology comprises the following steps: base preparing, inoculating and cultivating, spraying, pre-fermenting, hair-rubbing and pickling, and soup-filling. According to the technology, the bases are prepared by steam-boiling of soybean slurry; a mixed spore suspension of hair mould and Rhizopus oryzae is utilized in grafting; table salt is used for hair-rubbing and curing of the bean-curd white bases, wherein the weight of the table salt is 10-14% that of the bean-curd white bases; and alcohol with the alcoholicity being 16-20% is used for soup-filling. The fermented bean curd is prepared under multi-aspect coordinated actions, so that the prepared final products are small in individual difference and batch difference. The prepared low-salt fermented bean curd is good in appearance and taste and is not prone to deterioration.

The fertilizer contains various elements for plant growth, and can effectively promote growth, improve physical and chemical properties of soil and promote absorption and utilization of various elements by plants. The fertilizer contains humic acid, can improve the problems of soil salinization and hardening, and can be prevented from being dissolved when being mixed with a chemical fertilizer due to the effect of a seaweed fertilizer coating. The product contains a large amount of beneficial bacteria and fructo-oligosaccharide, and the fructo-oligosaccharide can provide nutrients for microorganisms and prevent the microorganisms from being inactivated in the product storage process. The beneficial bacteria are high in activity and high in fertility, and the soil quality can be improved.

The invention provides a preparation method of a metal protective agent. The method comprises successively mixing evenly water, silane coupling agents, water-soluble silicate, a silica filler and water-soluble film-forming resin. The invention also provides the metal protective agent prepared according to the preparation method and a use thereof in preparation of metal materials. The invention further provides a hot-dip plated metal material which comprises a hot-dip plated metal substrate and a coating layer adhering onto the hot-dip plated metal substrate, wherein the coating layer is a cured product of the metal protective agent. A protective film formed by the metal protective agent provided by the invention is quite excellent in corrosion resistance. In addition, the metal protective agent provided by the invention is quite excellent in storage resistance, and can be stored for 180 days at room temperature after completion of preparation but does not generate obvious character changes and performance reduction.
