Classification of Noodles and Development of Gluten‐free Rice Noodle
Noodlesare classified into guksoo (noodle), naengmyeon, dangmyeon, instant fried noodle, pasta, and other noodles in Korean food code. The main ingredients of Asian noodles are wheat, rice, and buckwheat and starches from potato, sweet potato, mung bean and pulses. The people in northeast Asia countries, Korea, China, and Japan have been eaten hand‐elongated and cut noodles, but rice noodles with pregelatinization are most commonly used in the cuisines ofSoutheast Asia. Pasta is made from semolina (durum wheat) by extrusion.For most Japanese and Korean, the preferred textural properties of boiled regular salted noodles are soft and elastic with a smooth surface. Most Chinese, however prefer noodles with firm, elastic, and chewy texture. Rice noodles have not functionality of wheat gluten in forming continuous viscoelastic dough. There are two main methods used for the production of rice noodles: extrusion, which is used to produce vermicelli types; and sheeting of a rice flour batter, which is used to produce sheet and flat noodles. To develop the white salted rice noodle prepared from dry milled rice flour after drying with soaked rice grains, transglutaminase, propylene glycol alginate, adequate water and protein source were added to form gluten‐like network matrix and to entrap starch granules inside of protein matrices. The color and cooking behavior of noodle dough, and texture and sensory test of cooked noodles were investigated. The soy protein, mung bean protein, and silkworm protein helped to form a gluten‐like matrix crosslinked with rice protein. Propylene glycol alginate contributed smooth and elastic texture and reduced the cooking loss, in contrast with gelatinized and extruded rice noodles.
