    摘要： Disclosed is a method for manufacturing an iron catalyst, the method including: a mixing stage where a mixture solution is manufactured by mixing iron nitrate (Fe(NO3)3) solution and copper nitrate (Cu(NO3)2) solution; a precipitation slurry-forming stage where a precipitation slurry is formed by adding at least one of sodium carbonate (Na2CO3) or sodium hydroxide (Na2CO3) solutions to the mixture solution; a washing stage where the precipitation slurry is filtered and washed with distilled water; a silica adding stage where fumed silica powder and potassium carbonate (K2CO3) solution are added to the precipitation slurry and then agitated; a drying stage where the precipitation slurry is passed through a sieve having a size of 30 μm to 100 μm and dried by a spry drying method to manufacture a powdered iron catalyst; and a heat treatment stage where the iron catalyst is dried at a temperature of 50° to 150° C., and then heat-treated at a temperature of 300° C. to 500° C.

    摘要翻译： 本发明公开了一种铁催化剂的制造方法，其特征在于，包括：将硝酸铁（Fe（NO 3）3）溶液与硝酸铜（Cu（NO 3）2）溶液混合，制成混合溶液的混合阶段; 沉淀浆液形成阶段，其中通过向混合物溶液中加入至少一种碳酸钠（Na 2 CO 3）或氢氧化钠（Na 2 CO 3）溶液形成沉淀浆料; 洗涤阶段，其中沉淀浆液被过滤并用蒸馏水洗涤; 二氧化硅添加阶段，将沉淀二氧化硅粉末和碳酸钾（K 2 CO 3）溶液加入沉淀浆料中，然后搅拌; 将沉淀浆料通过尺寸为30μm至100μm的筛子的干燥阶段，并通过干燥法干燥以制造粉末状铁催化剂; 以及铁催化剂在50℃〜150℃的温度下干燥，然后在300℃〜500℃的温度下进行热处理的热处理阶段。

    摘要： The present invention disclose a method for preventing discoloration of walnut during cooking by adding caustic soda, a cooking process of walnut porridge of which discoloration is inhibited, and walnut porridge prepared by the same. The addition of the caustic soda neutralizes tannic acid contained in the inner shell of the walnut causing discoloration of walnuts during cooking. The inventive walnut porridge retains the walnut's intrinsic color, having experienced the least discoloration into dark greyish color during cooking, and exhibits enhanced sensory attributes without losing its natural taste.

    摘要翻译： 本发明公开了一种通过添加苛性钠，烹饪过程中防止变色的核桃粥的烹饪过程以及由其制备的核桃粥来防止核桃在烹调过程中变色的方法。 加入苛性钠可以中和核桃核壳中所含的单宁酸，导致核桃在烹饪过程中变色。 本发明的核桃粥保留了核桃的内在色彩，在烹饪过程中经历了最少变色为深灰色，并且表现出增强的感官属性，而不失去其天然味道。
