Abstract
本發明係為含有S-腺苷基-L-甲硫胺酸;與由羧甲基纖維素、羥丙基纖維素、大豆多糖類、酪蛋白鈉及玉米蛋白中選出之至少1種添加物之組成物,且為S-腺苷基-L-甲硫胺酸係由培養具有S-腺苷基-L-甲硫胺酸生產能力之微生物而得之含有S-腺苷基-L-甲硫胺酸之菌體中萃取者,該組成物中之該添加物之含量,相對於該組成物中之S-腺苷基-L-甲硫胺酸之質量比為0.05~15倍量之範圍的組成物、使用該組成物之成型體及該組成物之製造方法。本發明提供高濃度含有有用於作為水溶性生理活性物質之S-腺苷基-L-甲硫胺酸之保存安定性優良、進而生體吸收性優良的組成物、使用該組成物之成型體及該組成物之製造方法。
Description
本發明係關於含有高濃度之有用於作為水溶性生理活性物質的S-腺苷基-L-甲硫胺酸之保存安定性優良的組成物、使用該組成物之成型體及該組成物之製造方法。
S-腺苷基-L-甲硫胺酸(以下表記為SAMe)在生體內係廣泛存在。SAMe係於核酸、神經傳導物質、磷脂質、荷爾蒙、蛋白質等之合成/代謝中,作為各種甲基轉移酶之甲基化反應的甲基供給體而扮演重要角色的水溶性生理活性物質。SAMe幾乎在人體所有細胞均可見,作為各樣之生化反應中的共同因子而作用,且係藉由甲基轉移、硫基轉移、及胺丙基轉移之3個代謝路徑被代謝。例如,係軟骨維持或腦內物質之生合成所不可欠的物質。由近年來之SAMe功能研究,亦被報導對於脂肪肝、高脂血症、動脈硬化症、失眠症、酒精性肝炎、老人性痴呆症等之治療效果。SAMe為如此重要之生理活性物質,於歐美各國作為憂鬱症、肝臟疾病及關節炎等之治療藥、或健康食品而廣為利用。
因此,以便宜價格、簡便地製造供給SAMe,係強力地被期望。以往,作為SAMe之製造方法,已知有使用前驅物之含有L-甲硫胺酸的培養基以發酵生產之方法、使用由微生物單離純化之SAMe合成酵素(甲硫胺酸腺苷基轉
移酶),以腺苷酸5’-三磷酸(ATP)與L-甲硫胺酸為基質,而酵素合成SAMe之方法及以合成法之方法等。
酵素合成法,係使用由微生物單離純化的SAMe合成酵素(甲硫胺酸腺苷基轉移酶),以腺苷酸5’-三磷酸(ATP)與L-甲硫胺酸為基質來酵素合成SAMe之方法。此方法相較於發酵法,係有SAMe之生成量多、不須由菌體進行SAMe萃取操作等之優點。但是,係有酵素之調製繁雜、所得之酵素的活性微弱、有必要去除ATP分解酵素等妨害物質、再者基質之ATP極為高價格等各樣的問題,而不必然為實用的方法。
又,因近年來基因工程之發展,藉由使用經選殖之SAMe合成酵素基因來調製該酵素變得更簡便,酵素調製之問題逐漸得到解決。但是,必須使用高價格的ATP作為基質等其他實用上的問題依然尚未解決。
又,SAMe係有對熱不安定而在常溫亦容易分解的性質,故作為醫藥品、健康食品使用時會成為一大障礙。作為其對策,進行了以提高保存安定性為目的之多數嘗試。通常例如係為將以前述製造方法而得之SAMe的組成物藉由層析法等純化後,藉由成為與硫酸或對甲苯磺酸之鹽,或與丁烷二磺酸之鹽等,而實現SAMe之安定化的方法;或對純化之SAMe進行添加物處理,作為SAMe組成物而實現安定化之方法。但是,需要大量勞力與費用,故以便宜價格製造且提供作為治療藥或健康食品而重要之SAMe,係極為困難。
而近年來,已進行關於使用可更便宜、純化步驟少、且簡便地製造SAMe之具有SAMe生產能力且可經口攝取之微生物的含有SAMe之微生物(例如參照非專利文獻1)、含有SAMe之微生物萃取物的研究(例如參照專利文獻1~4、非專利文獻2)。但是,現狀之含有SAMe之微生物萃取物,相較於經純化之SAMe、SAMe組成物,保存安定性低會成為問題。

製程、使用該組成物之成型體。
本發明之發明者等,為了解決上述課題,關於含有高濃度之SAMe、且可在安定狀態下長期間保存的組成物,進行努力探討的結果,發現含有含有SAMe之酵母菌體與特定之增黏劑之含有SAMe之乾燥酵母組成物,其保存安定性優良,而進行專利申請(參照專利文獻5)。但是,針對含有由含有SAMe之酵母菌體萃取之含有SAMe之萃取物的組成物,則尚無探討。
因而,本發明者等,對利用含有SAMe之萃取物,含有高濃度的SAMe、且可在安定狀態長期間保存之性能優良的組成物;及可經濟地生產該組成物之方法進行努力探討的結果,發現藉由以下所示項目能夠解決,而完成本發明。

以下,詳細說明本發明。
本發明之保存安定性優良且含有高濃度之SAMe的組成物,係含有由培養微生物而得之含有SAMe之微生物菌體中萃取而得之SAMe與特定之添加物。
再者,含有SAMe之組成物中,大量含有5'-核苷酸、遊離胺基酸、具有抗氧化作用且有用於肝功能改善之麩胱甘肽、具有免疫力增進作用或整腸作用之β-聚葡萄糖或食物纖維等之有用成分,作為健康食品等而廣泛被利用。
本發明中所使用之微生物的種類,只要具有SAMe生產能力且能夠經口攝取者即可,可列舉例如屬於酵母菌(Saccharomyces)屬、念珠菌(Candida)屬、畢赤酵母菌(Pichia)屬、毛黴菌(Mucor)屬、根黴菌(Rhizopus)屬、短桿菌(Brevibacterium)屬、棒狀桿菌(Corynebacterium)屬、埃希氏菌(Escherichia)屬、鏈絲菌(Streptomyces)屬等之微生物。此中,較佳為屬於酵母菌屬之微生物、特別以啤酒酵母菌
(Saccharomyces cerevisiae)更適合。
培養微生物時使用的碳源,只要係微生物能夠營養利用者則無特殊限制,可列舉例如葡萄糖、蔗糖、澱粉、廢糖蜜等碳水化物;乙醇等之醇類;或乙酸等有機酸。氮源亦只要是所使用之微生物能夠營養利用者則無特殊限制,可列舉例如含有氨、硝酸、尿素等無機體氮化合物;或微生物萃取物、麥芽萃取物等有機體氮化合物者。又,無機鹽類可使用磷酸、鉀、鈉、鎂、鈣、鐵、鋅、錳、鈷、銅、鉬等之鹽。進一步地,亦可添加與SAMe之骨架構成相關的甲硫胺酸、腺嘌呤、腺苷基核糖核苷來培養。
培養溫度及培養液之pH雖隨所使用之微生物種類而相異,但可列舉培養溫度20~35℃之範圍、培養液之pH為pH4~7之範圍。
又,為了提高菌體內之SAMe含量,較佳為好氣培養。培養槽,只要係可通氣且可依需要攪拌者即可,可利用例如機械攪拌培養槽、氣升(air lift)式培養槽及氣泡塔型培養槽等。
培養基之供給方法,係將碳源、氮源、各種無機鹽類、各種添加劑等一起或個別連續地或間歇地供給。例如,蔗糖、乙醇等之基質可作為與其他培養基成分之混合物對培養槽供給、又亦可與其他培養基成分各自獨立地對培養槽供給。
培養液之pH控制係藉由酸、鹼溶液來進行。鹼較佳為使用作為氮源來使用的氨、尿素;或非氮系鹼、例如苛
性鈉、苛性鉀等來控制pH。酸可使用無機酸、例如磷酸、硫酸、硝酸、或有機酸。再者,亦可使用無機鹽類之磷酸鹽、鉀鹽、鈉鹽、硝酸鹽等來控制pH。
在如此條件下培養,於目標量之SAMe累積於微生物菌體中之階段將培養液抽出,分離微生物菌體。分離方法只要係能夠有效率地進行菌體之分離與洗淨的方法則無特殊限制,但可列舉使用逆流型之酵母分離器或分離膜之超微過濾裝置作為適合的例子。

得到含有SAMe之萃取液的方法,可列舉對於經分離之微生物菌體之分離濃縮物添加蛋白質分解酵素、細胞壁溶解酵素等而萃取之方法;利用微生物中之酵素藉由自我消化而萃取之方法;藉由高壓分散處理等之高壓粉碎而萃取之方法;添加礦酸、有機酸而混合之方法;加熱處理之方法等。
含有SAMe之萃取液,相較於含有SAMe之微生物菌體,固體成分少,容易分散、溶解於水,可容易地添加於食品、調味料等。又,能夠濃縮SAMe成分。
本發明中使用之添加物,係由羧甲基纖維素、羥丙基纖維素、大豆多糖類、酪蛋白鈉及玉米蛋白中選出之至少1種。該等添加物可單獨或組合2種以上來使用。其中更佳為羧甲基纖維素、羥丙基纖維素、大豆多糖類。
大豆多糖類,係以半纖維素為主成分之水溶性多糖類,係有由半乳糖、阿拉伯糖、半乳糖醛酸、木糖、岩藻糖、鼠李糖等之糖所構成的多糖類,具體而言可適合使用Freund產業股份有限公司製之市售品(商品名「Hemilose」)。玉米蛋白係為來自玉米的蛋白質,亦可使用該蛋白質水解物或鈉鹽或鉀鹽等之鹽。本發明中,藉由使用特定之添加物,組成物中之SAMe的保存安定性會提高,進一步地SAMe之生體吸收性會提高。本發明中使用之添加物,係於食品、化粧品、醫藥品用途被廣泛運用,可安全地使用。該等添加物,可使用適當合成者、亦可使用市售品。
添加物之添加量,必須於乾燥前的含有SAMe之萃取液中相對於SAMe之質量比成為0.05~15倍量之範圍、較佳為成為0.1~13.5倍量之範圍、更佳為成為0.15~13.5倍量之範圍。添加物之前述添加量低於0.05倍量時,組成物中之SAMe的保存安定性變得不充分,超過15倍量時僅會浪費、或該組成物中之SAMe的保存安定性會隨用量依存地顯示降低的傾向。
含有SAMe之萃取液與添加物的混合時間較佳為1分鐘~24小時的範圍。低於1分鐘時組成物中之SAMe的保存安定性會變得不充分;超過24小時時僅會浪費、或有該組成物中之SAMe成分減少的可能性。混合中該組成物中之SAMe的保存安定性、進而生體吸收性增加,且後述之該組成物之乾燥步驟中的良率亦提高、且含有SAMe之
組成物獨特的臭氣亦被遮蔽。
添加物之添加混合處理進行後,藉由使液狀之組成物乾燥,使水分蒸發,成為固體之乾燥組成物。乾燥方法、噴霧乾燥器之噴霧乾燥法、冷凍乾燥法等方法。
作為乾燥條件,噴霧乾燥法中,較佳為以入口溫度210℃以下、出口溫度110℃以下來乾燥。冷凍乾燥法中,較佳為以最終棚架溫度30℃以下來乾燥。本發明之乾燥組成物,由保存安定性的觀點來看,希望使其水分含量為5.0質量%以下、較佳為3.0質量%以下、更佳為1.0質量%以下。
組成物中之添加物的含量,相對於組成物中之SAMe的質量比為0.05~15倍量之範圍、較佳為0.1~13.5倍量之範圍、更佳為0.15~13.5倍量之範圍。添加物之前述含量低於0.05倍量時,組成物中之SAMe的保存安定性變得不充分、超過15倍量時該組成物中之SAMe的保存安定性會隨用量依存地顯示降低的傾向。
組成物中之SAMe含量,較佳為相對於組成物之乾燥質量為1質量%以上、更佳為3質量%以上、更佳為8質量%以上。
所得之乾燥組成物為固體,可容易地成型加工。使用此乾燥之含有SAMe之組成物所成型的成型體係使用於各種用途。例如、使乾燥之含有SAMe之組成物破碎而成為粉末狀、或於粉末狀之含有SAMe之組成物中依需要添加其他生理活性成分或賦形劑等添加劑後,壓縮打錠使成為
錠劑狀的組成物,亦可進一步被覆其表面。又,亦可使粉體造粒為顆粒狀、或將粉體或經造粒之顆粒填裝為膠囊化。
以下,以實施例及比較例進一步詳細說明本發明,但本發明不受該等例子限定。
