Xuchang yuba, known as the "Suizhongzhi". Xuchang Yuba is a traditional Han dish in the Xuchang area of ​​Henan. The color of yuba is golden, the color is bright, the honeycomb is even, and after frying, it is fried, fried, boiled and other processing methods. It tastes delicious and delicious, and is very popular among people. After the soybean is refined, it is condensed and dried. Because it is empty like bamboo, it is called yuba, and because it is mainly produced in Xuchang River and Qingyi River in Xuchang, Henan Province, it is named Xuchang Yuba.

The definition of this layer from yuba is enough to show that Xuchang yuba is deeply rooted in the hearts of the people. In Xuchang and even in Henan, as long as the town of Hechang in Xuchang County is mentioned, the first thing people think of is yuba. For decades, the yuba produced by Hejie has been placed on the dining table of thousands of households. When people taste the delicious flavors of beans mixed with yuba, braised yuba, and fried yuba, they can't help but ask: This is not the yuba of the river street?u0026quot;Therefore, the name of the river street is accompanied by yuba and deep into the hearts of the people, becoming a synonym for the indivisible yuba. u0026quot; The origin of yuba is on the river street. u0026quot;Xuchang Yuba originated in the 50s and 60s of the last century. There is a Linghe River on the river street. The water quality of the Linghe River is clear and sweet, and the name of the river street is named after it. The village near Hejie Street has a tradition of grinding tofu. The tofu is sharp and tender, and has a delicious taste. At that time, in the Dangwangzhai Village of Hejie Township, there was a farmer who cooked the bean curd soymilk because the soy milk cooked for a long time, and the soybean milk had a layer of skin on it. Therefore, the farmer pinched the layer of leather and hung it on a bamboo pole next to the bean curd pot. After the farmer had finished grinding the tofu, he found that the layer of leather he had hung on the bamboo raft had condensed into strips, and the middle of the space was like bamboo, and the appearance was golden yellow and shiny.掰 The next cut into the mouth to chew, taste and very strong. Afterwards, the farmer informed his villagers about the villagers who grind the tofu, and everyone said that they had similar findings. Later, when there was a person in the village who was grinding tofu, he no longer used soda pulp with acid pulp, but deliberately went to cook the soy milk, and then pinched the layer of soybean oil that had been condensed on the bamboo pole to dry it. This new product. Because the shape of this bean product is slender, hollow like bamboo, and it was originally hung on a bamboo pole to dry, the local villagers nicknamed it yuba. The color of yuba is golden, the color is bright, the honeycomb is even, and after frying, it is fried, fried, boiled and other processing methods. It tastes delicious and delicious, and is very popular among people. As a result, villagers in the villages near Hejie followed suit, and they set up pots at home, and improved the use of flat-bottomed woks to cook soy milk and process yuba. In addition, the production of yuba has also driven the development of related industries such as planting, aquaculture, transportation, printing and packaging, and food processing machinery. The slag produced by yuba is a good ingredient for raising pigs. Almost all professional yuba households are professional pig farmers. The township has more than 5,000 large pig farmers and 45,000 annual pigs. It is named as Xuchang pig production base. The production of soy products in the township has also formed an industrial chain of more than 10 brands in five series including bean curd, bean silk, plant meat and tofu.

Xuchang yuba quality technical requirements (a) raw materials. 1. Soybean: Produced in the Xuchang area, north latitude 33 ° 42 ' to 34 ° 24 ' and east longitude 113 ° 03 ' to 114 ° 19 ', soybean water soluble protein (dry basis) ≥ 35%. 2. Processing water: from the Shiliang River and Qingjian River Basin in the protected area, the water quality meets the sanitary standard of drinking water, calcium ion ≤ 40mg / L, magnesium ion ≤ 15mg / L, sulfate ion ≤ 200mg / L. (2) Production requirements. 1. Process: Soybean→Selection→Immersion→Refining→Filtering→Boiled Slurry→Cooling→Gluing→Peeling→Drying→Packaging 2. Technical Requirements: (1)Selection: Select full of particles, yellow color Bright soybeans, which remove impurities and decayed bad beans through sputum, sieve, panning, and sputum. (2) Immersion: Immerse the selected soybeans in water, which is 2 to 2.5 times that of soybeans, 10 to 12 hours in spring and autumn, 6 to 8 hours in summer, and 23 to 25 hours in winter. The water to be soaked is basically sucked dry, and a small amount of water is added to turn the soybeans over again to "wake up". (3) refining and filtration: the soaked soybeans are beaten and filtered, and the mesh number is 120 to 140. Then, water is added to control the amount of soybean milk between 8 and 10 times, and the concentration of soybean milk is controlled at 6.5%. To the range of 7.5%. (4) Cooking, cooling and grouting: The directly heated method is used to heat the filtered soybean milk to 100 ° C for 3 minutes to 5 minutes, then cooled to 80 ° C ± 5 ° C and injected into the forming pot. (5) Lifting: The soymilk in the forming pot is continuously heated, the temperature is controlled at 80 ° C ± 5 ° C, and the peeling is carried out when the thickness of the soy milk conjunctiva is greater than 20 μm. (6) Drying: The yuba is dried at 75 ° C ± 3 ° C for 3 hours to 4 hours, and then dried at 65 ° C ± 3 ° C for 3 hours to 4 hours. (7) Packing: The moisture content of yuba is packaged between 8% and 12%. (3) Quality characteristics. 1. Sensory characteristics: yuba is light yellow, uniform color; thin strips, fine texture, no short strips and fragments, no visible impurities, no mildew and insects; good toughness, long-term cooking, taste It has a unique bean flavor, a sweet taste, a delicious taste and no odor. 2. Physical and chemical indicators: water ≤ 12%, protein ≥ 38%, fat ≥ 16%. 3. Safety requirements: Product safety indicators must meet the relevant regulations of the state for similar products.
