Abstract
Description
で表される化合物(以下、「化合物(I)」ともいう)を1種又は2種以上含有し、該化合物の濃度の合計が1ppm以上である飲食品を提供する。本発明の飲食品は化合物(I)を1ppm以上含有するため、乳酸菌及び/又はフラットサワー菌に対して抗菌活性を示し、乳酸菌及び/又はフラットサワー菌の混入による飲食品の品質低下を抑制することができる。
で表される化合物を1ppm以上含有する。
(抽出エキスの調製)
市販の食用植物(表1及び2に記載)の葉、茎又は根を粉砕したものに、粉砕物と等量の滅菌水を加えボルテクスにて撹拌混合し、室温で1時間静置した。この混合物に滅菌水の3倍量のエタノールを添加し、インキュベーターで50℃、120rpm(往復振盪)の条件で3時間抽出し、75%エタノール抽出液を得た。この抽出液を3000rpmで10分間遠心処理し、各抽出エキスを得た。
(しょうゆの調製)
市販減塩しょうゆ(キッコーマン社製)を滅菌水で2倍希釈し、水酸化ナトリウムでpH4.8に調整し、加熱殺菌を行って、試験用減塩しょうゆを調製した。
(抗菌作用の評価)
試験管に試験用減塩しょうゆ11.3mL、各抽出エキス0.7mL及び乳酸菌(Lactobacillus rennini及びLactobacillus acidipiscis)を終濃度105cfu/mL程度となるように添加し、シリコ栓をし、30℃で静置して嫌気培養を行った。乳酸菌が増殖すると菌体の沈殿が生じることから、経時的に試験管の底に生じる沈殿を観察し、コントロール(抽出物の代わりに75%エタノール水溶液を加えたもの)と各抽出エキスを添加した試験との沈殿が生じるまでの日数を比較し、抗菌作用の評価を実施した。結果を表1及び2に示す。
試験例1において抗菌作用(増殖までの日数がコントロールと比較して7日以上の差)が認められた抽出エキス19種の香りと味の観点から素材として適しているかについて、訓練されたパネル1名により以下の評価基準で官能評価を実施した。結果を表3に示す。なお、表中において使用部位については、1は種子(種皮)又は果実(果皮)、2は葉、茎、花又は幹、3は根をそれぞれ示す。
