Rice noodles

Rice noodles are noodles made with rice flour and water as the principal ingredients. Sometimes ingredients such as tapioca or corn starch are added in order to improve the transparency or increase the gelatinous and chewy texture of the noodles. Rice noodles are most common in the cuisines of China, India and Southeast Asia. They are available fresh, frozen, or dried, in various shapes, thicknesses and textures. Fresh noodles are also highly perishable; their shelf life may be just several days.

The origin of rice noodles dates back to China during the Qin dynasty when people from northern China invaded the south. Due to climatic conditions, the northern Chinese have traditionally preferred wheat and millet which grew in cold weather while the southern Chinese preferred rice which grew in hot weather. Noodles are traditionally made out of wheat and eaten throughout northern China so to adapt, northern cooks tried to prepare "noodles" using rice, thus inventing rice noodles. Over time rice noodles and their processing methods have been introduced around the world, becoming especially popular in Southeast Asia. In India, idi-appam, strings of cooked rice, was known in ancient Tamil country around 1st century AD, as per references in the Sangam literature, according to food historian K. T. Achaya.

The shelf life may be extended by drying and removing its moisture content. Studies of drying rice noodles were conducted by the International Food Research Journal.

Pasta made from brown rice flour is also available (in health food stores in Western nations) as an alternative to wheat flour-based noodles for individuals who react poorly to gluten.
