Abstract
Description
これらの飲食品等にビフィズス菌を添加する場合、予め培養したビフィズス菌を加工して添加するが、その加工には多大な労力及び時間を要し、また加工において高い生残率を維持するためには技術的に極めて困難な点があった。
一方、乳酸菌等は古くからヨーグルト・チーズ等多数の乳製品にスターターとして利用されている。また近年、その整腸作用のみならず、免疫調節作用(例えば、非特許文献2参照)や炎症性腸疾患改善作用(例えば、非特許文献4参照)等のプロバイオティクス機能を期待して、種々の食品に添加されている。
しかし従来これらの乳酸菌等は牛乳等で培養することによりその菌体を取得しているが、そのために多くの労力と多大な時間を要し、また、菌体の品質管理等について十分に注意をしなければならないという問題があった。
従って、予め凍結又は凍結乾燥した乳酸菌類の生菌体を用いることにより、乳酸菌類を含有する飲食品、例えばヨーグルトやチーズ等の乳製品が簡単に製造することができる。しかしながら、これらの製品に必要な菌濃度を有する凍結又は凍結乾燥乳酸菌類を調製することは、融解時又は凍結乾燥時において、菌体が被る損傷又は死滅を防止しなければならないため、極めて困難であった。
従来、これらの問題を解決するために多くの凍結保護物質及び凍結乾燥保護物質が開発された。これらの物質には、脱脂乳・グルタミン酸ナトリウム・ゼラチン及びショ糖(例えば、特許文献1参照)・フェニルアラニン・ヒスチジン・クエン酸・コハク酸・酒石酸及び炭酸アルカリ(例えば、特許文献2参照)等が知られており、その他に、乳糖・トレハロース・脱脂粉乳・ソルビトール・アスコルビン酸ソーダ(例えば、非特許文献5参照)等も知られている。
更に、凍結又は凍結乾燥菌体の製造工程においては、菌体分散液を凍結する速度が菌体の損傷又は死滅において甚大な影響を与える。即ち、可及的速やかに液温を低下させることが望ましいが、工業的規模で製造する場合には、急速凍結を実施する上で克服しなければならない問題が多数存在していた。
