【発明の属する技術分野】
本発明は、高品質の米粉パンの製造法に関し、更に詳しくは、グルテン含有米粉に細胞壁分解酵素類、アミラーゼ類、食品用乳化剤及びイーストの発酵促進剤の1種又は2種以上を適量添加することによって高品質の米粉パンを製造するための米粉パン製法の改良に関するものである。
【0002】
【従来の技術】
従来、米は米飯として、粒食の用途が大部分であり、粉食用途としては団子、米菓、打物等の和菓子に限られ、小麦粉の様な広範囲の加工利用は行われてこなかった。しかしながら、最近、米を多量の損傷デンプンを出すことなく微粉砕する技術が開発され、米粉の飛躍的な需要拡大を目的として米粉パンに関する研究が行われている。
【0003】
しかしながら、これまでの検討は主に米の製粉方法の改善と得られた米粉をパンに利用するための製パン条件の改良について行われてきた。そして具体的な開示例として、前者については、特許文献1、特許文献2、特許文献3、特許文献4が、後者については、特許文献5、特許文献6、特許文献7、特許文献8等が挙げられる。しかしながら、これらの技術によって米粉の製パン性がかなり向上しているが、未だに強力小麦粉のそれには及ばず米粉を用いて十分な品質のパンが製造できていないのが現状である。
