After liberation, dozens of private workshops merged and joined Beijing No.1 Food Factory, and "Children's Crisp" became a famous product of this factory. 1963, they successfully developed "red shrimp crisp candy" again, which soon became an export product and sold well in the international market. For decades, the output has been increasing, which still can't meet the needs of merchants. Red Shrimp Crisp was awarded the Silver Medal by the State Council. The characteristics of red shrimp crisp can be summarized as "crisp, crisp, fragrant and sweet". In the production, the essence of traditional craft is concentrated, and the materials are exquisite. All of them are made of high-quality Liuhua sugar, high-concentration glucose syrup and "Erba sesame sauce", which are boiled, pulled and folded for many times. This kind of sugar is thin and crisp, with clear layers of sugar stuffing, sweet and delicious to eat, and does not stick to teeth or greasy mouth, leaving no residue after eating.
