Gullon is the largest biscuit manufacturer in Spain, with a market share of about 30%. Spanish biscuit products are famous all over the world, with an annual output of up to 100 million tons, exported to many countries around the world, and Guyou is the largest Spanish biscuit brand in export business, becoming the representative of Spanish biscuits.
 
Guyou has played an integral role in the Spanish biscuit market, creating the first graham biscuit in the Spanish market in 1979 and the first biscuit made with vegetable oil in 1986, which contributed to the formation of the Spanish healthy biscuit market. Today, Guyou has three large-scale biscuit production plants in Europe, and its second factory, which opened in 2003, is currently the largest biscuit production plant in Europe.
 
Guyou biscuits have a rich product line, including Maria series, cookie series, sandwich biscuits and digestive biscuit series. Most of Guyou biscuits are coarse grain biscuits such as oatmeal cakes, mainly whole wheat flour, with a high dietary fiber content, the content reaches 11g/100g, the wheat fragrance is natural, the sugar content is slightly reduced, and the sweetness is relatively natural, but the oil content is almost the same as that of ordinary crispy biscuits. In addition, 30% oatmeal is added, which is full of grains and has a crispy texture. Its fruit flavor contains grapes, apples, kiwi and other fruits, the fruit is sweet, fresh and natural, and has a strong sense of satiety, and is often used as a breakfast cake.
 
Although whole grain biscuits often claim to be richer in dietary fiber, they do not mean they are healthier. In order to achieve the crispy effect of biscuits, a lot of fat is usually added, even if the dietary fiber content is high, its benefits may not be the best to be used, and it is generally necessary to have a low oil and sugar content.
 
Guyou's Maria biscuits are also one of its most popular and representative products, in addition to being eaten daily as snacks and refreshments, Maria biscuits are often used as raw materials to make wood bran cup desserts. When making, the Maria biscuits are crushed, whipped with whipped cream and condensed milk, spread on the biscuit crumbs, overlapped layer by layer, and can be made into a wooden bran cup after 2 hours of quick freezing. This chaff cup dessert melts in the mouth and has a sweet taste, which is loved by dessert lovers and bakers alike. In terms of price, the unit price of Guyou biscuits is mostly around 20 yuan, which is relatively affordable.
