Noodles prepared with caustic soda (sodium hydroxide, NaOH) tend to be stickier and not as firm as those made with kansui reagents (a mixture of sodium and potassium carbonates in different ratios). It has a detrimental effect on gluten development as well as causing premature starch gelatinization and increased noodle stickiness. The composition of the alkaline solution (kansui) added to the flour can have a significant effect on the brightness (L*) and yellowness (b*) of the alkaline noodle (see Table 7.5). 37 Flour used to prepare alkaline noodles has been found to contain lower amounts of non-starch lipid, most noticeably the neutral/polar lipids, as compared to those used for the production of salted noodles. 38 Alkaline noodle flours tend to have larger particles than salted noodle flours. 39 7.4.2 Processing Aside from Korea and Japan the majority of noodle processors are small familyoperated businesses catering to local or neighborhood clients. Usually these small operations have only a few bags of flour dropped off on a daily basis. Many mills provide technical expertise for these small operations identifying which of their flour products are best suited to their clients’ needs. In these small operations flour specifications are not usually discussed although a client will immediately contact his supplier if the final product is unacceptable for any reason. Larger noodle processors generally have one or two flour silos on site which are filled continuously on a regular basis. A large plant can process over 240 tonnes per 24 hours. It is not uncommon for the flour companies to build
