The appearance of the yuba is bright and lustrous, and it is light yellow; the taste is pure, sweet and fragrant, no smell, good toughness, chewy, non-sticky after water swelling, especially in the same kind of products. The protein content is as high as 48.8%, the fat content is 25.1%, and cholesterol and saturated fat are very low. It also contains trace elements such as sugar, iron, calcium, phosphorus, and thiamine, riboflavin, and niacin. Because it contains phytonutrients, it is called "the most vegetarian".

[Geography of the landmarks] Yunantuodong is located at the southern margin of the Tropic of Cancer. It has a low latitude and is a subtropical humid monsoon climate. It is short in summer and long in winter, and is 7 months in summer. It has sufficient sunshine and an average annual temperature of 21.5 °C. It is only affected by the winter cold wave. The frosty day occurs; the average annual rainfall is 1610 mm, and the rainfall is abundant; the soil is dominated by red soil, and the fertile soil is deep and rich in organic matter. According to research, the climatic characteristics of low latitude, high temperature, good rain, good sunshine and rich soil organic matter are conducive to the production of high quality soybeans. High-quality soybeans provide good raw materials for the production of tong yuba, and sufficient sunshine also facilitates the drying of the yuba. Located in the vicinity of Dayunwu Mountain, Fulin, Tuodong and other places are the most rainy areas in Yun'an County, with abundant rainfall. Yun'an County is a national greening model county and a forestry ecological county in Guangdong Province. The natural mountain spring water in the first peak of the county is especially clear and pure, and the water quality is superior. According to the inspection by the local quality inspection department, the water used for the production of yuba yuba--the pH value of Dayunwushan Mountain Spring is 6.99, which is very close to neutral water; the total hardness is 34.2mg/L, which is far below the national standard limit of 450 mg/ L. It is the unique water quality of the large cloud mountain spring water, which has created the unique taste and good quality of the yuba. [Cultural background] Legend has it that one day in ancient times, the god of food gods passed through Yunqing Village (now Yunxing Village, Tuodong, Yun'an County), and found that the locally made tofu is particularly delicious and delicious, so the body of a tofu master named He Shi in Yunxing Village On the body, I am full of food. The next morning, He Shigang boiled the soy milk to prepare tofu, and suddenly heard the neighbor yelling "Fire Wish" (fire), and quickly put down his hands to run to fight the fire. When the rescue came back, more than ten barrels of soymilk had already been frozen, and a thick layer of soymilk was condensed on the surface. When he saw it, he picked up the bean film with chopsticks, dried it on the bamboo pole for drying clothes, and re-cooked the soy milk to make tofu. In the evening, He Shi found that the soymilk film on the clothespin had dried up, the color was thin and translucent, and it was cooked as a dish. I can't think of the soymilk film, which is tough and crisp, and the fragrance is very fragrant. The bean scent retains the teeth and can't help but scream for the best. It is amazing to hold it with the neighbors. When someone asks what to do about this, even the god of food attached to He Shi is speechless, because this is a mischievous and new creation of food, and even heaven does not have this thing. The god of food suddenly has a chance to move: "The bean curd film and conjunctiva, with the clothes drying and drying it, can be called 'attached bamboo', but only called 'attachment bamboo', it can not show its tofu pulp nature... 'attachment' and 'rotation' The same sound, it is called 'Yuzhu'!" [Cultural Accumulation] In 1999, won the bronze medal of the first youth "three high" agricultural fair in Guangdong Province, and participated in the China International Agricultural Expo held in Beijing; in 2001, was named The first batch of agricultural famous brand products in Yunfu City won the Guangdong Provincial Recommended Agricultural Products Award from the China International Agricultural Expo; on September 26, 2006, it was recommended to participate in the Guangdong Province Mountainous Agricultural Information Production and Marketing Conference; in 2010 and 2011 for two consecutive years It is recommended to participate in the Guangdong-Hong Kong Famous Brands Fair held in Macau. With the increasingly loud and sturdy brand of Tofu yuba, the yuba produced by farmers in Yun'an County is willing to sell under the name of succulent yuba. The yuba is more popular in Hong Kong, Macao and all over the country. [Brand Building] In January 2009, “Hong Kong God of Cookery” Liang Wenzhao specially went to Yunan to taste the Tofu yuba, and introduced it to Hong Kong Jade TV Station. Through the establishment of industrial brands, the monitoring of product quality is implemented in all production and operation and circulation links to ensure the quality characteristics of products, for other manufacturers to learn from, so that GI products can be innovatively developed in protection.
