多活性组分共包埋稳态化递送体系的加工方法与应用
技术领域
本发明属于新型健康食品加工技术领域,具体涉及多活性组分共包埋稳态化递送体系的加工方法与应用。
背景技术
近年来,随着大众对高品质生活的向往以及预期寿命的延长,人们对健康食品的要求日益提高。亲水性活性组分和疏水性活性组分在改善人类健康方面发挥重要作用,是健康食品的核心成分。目前,罗氏制药、帝斯曼、巴斯夫等国外主要健康食品生产供应商都开发了疏水性活性组分的脂质体、乳液、微胶囊、凝胶载体产品并形成了规模化的生产销售。而国内食品企业则多数局限于单一活性组分作为初级配料使用。因此,为了进一步拓展活性组分资源的开发利用,本发明旨在开发多活性组分共包埋稳态化递送体系的加工方法。
自然界中大多数活性组分可以从植物或者动物体内提取后,直接加入食品中。然而疏水性活性组分在水中的溶解度低,易受外界环境(温度、光照、氧气)、食品的加工贮存条件、消化道环境(pH值、酶、其他物质)的影响,进而降低其在食品和营养保健品中的生物利用度。因此,最大限度保留亲水性活性组分和疏水性活性组分的活性,改善疏水性活性组分的水溶性,提高活性组分的稳定性和生物利用率,实现活性组分的稳态化可控释放,是亟待克服的技术难题。
发明内容
技术问题:
提供一种操作简单方便、过程安全可控的亲水性活性组分和疏水性活性组分共包埋稳态化递送体系的加工方法,以解决亲水性活性组分与疏水性活性组分共包埋稳态化递送难题。
技术方案:
本发明的第一目的在于提供一种多活性组分共包埋稳态化递送体系的加工方法,依次包括如下步骤:
(1)将环化支链淀粉溶解于pH6.0-7.0的缓冲盐溶液体系得到环化支链淀粉质量浓度5%-40%的均一溶液,继续添加环化支链淀粉质量0.5-10倍的亲水性活性组分混匀,得到环化支链淀粉和亲水性活性组分的混合溶液;
(2)将疏水性活性组分溶解于纯乙醇,得到疏水性活性组分质量浓度为2-10%的溶液;然后将其添加到步骤(1)所得环化支链淀粉和亲水性活性组分的混合溶液中,搅拌混匀并调控混合体系中乙醇质量浓度达到35%以上;
(3)将步骤(2)所得体系置于功率200-500W、0-10℃超声场处理3-20min后,离心、沉淀干燥即得到目标产物——亲水性活性组分与疏水性活性组分共包埋稳态化递送体系。
作为本发明的一种实施方式,在步骤(1)中,将环化支链淀粉溶解于pH6.0-7.0的缓冲盐溶液体系得到环化支链淀粉质量浓度5%-25%的均一溶液。
作为本发明的一种实施方式,在步骤(1)中,环化支链淀粉与亲水性活性组分的质量比为1:(1~6)。
作为本发明的一种实施方式,在步骤(2)中,将疏水性活性组分溶解于纯乙醇,得到疏水性活性组分质量浓度为3-10%的溶液。
作为本发明的一种实施方式,在步骤(2)中,搅拌混匀并调控混合体系中乙醇质量浓度达到40~55%。
作为本发明的一种实施方式,在步骤(3)中,超声功率为200-450W。
作为本发明的一种实施方式,在步骤(3)中,超声处理时间为3-8min。
作为本发明的一种实施方式,所述环化支链淀粉的分子量为(3~100)×104g/mol,表面侧链平均链长DP>20,内部环状结构平均尺寸DP16~100且含α-1,6糖苷键5~10%。
作为本发明的一种实施方式,所述环化支链淀粉的分子量为(6~30)×104g/mol,表面侧链平均链长DP 25~50,环状结构平均尺寸DP20~40且含α-1,6糖苷键5~7%。
作为本发明的一种实施方式,所述环化支链淀粉采用如下步骤制得:将粮谷作物籽粒胚乳分级处理得到支链淀粉,添加来源于嗜热脂肪芽孢杆菌Q酶反应2-12小时后得到环化支链淀粉,其中Q酶转苷酶活力>150U。
作为本发明的一种实施方式,所述粮谷作物包括稻米、玉米和小麦中的至少一种。
作为本发明的一种实施方式,所述亲水性活性组分包括花色苷、蛋白短肽、水溶性维生素、栀子黄色素、抗性糊精、聚葡萄糖和矿物质中的至少一种。
作为本发明的一种实施方式,所述疏水性活性组分包括槲皮素、姜黄素、植物甾醇、β-胡萝卜素、白藜芦醇、叶黄素、番茄红素、辣椒素、亚麻籽油、鱼油和DHA藻油中的至少一种。
本发明的第二目的在于提供前述的方法制得的亲水性活性组分与疏水性活性组分共包埋稳态化递送体系。
本发明的第三目的在于提供前述的亲水性活性组分与疏水性活性组分共包埋稳态化递送体系在制备功能食品、药品或化妆品中的应用。
有益效果:
(1)本发明提供了一种操作简单方便、过程安全可控的亲水性活性组分和疏水性活性组分共包埋稳态化递送体系的加工方法,克服了亲水性活性组分与疏水性活性组分共包埋稳态化递送的技术难题。
(2)本发明利用环化支链淀粉的表面柔性侧链和内部环状结构特性,基于环化支链淀粉互作聚集组装包埋和溶剂共沉淀调控的技术原理,开发了一种多活性组分共包埋稳态化递送体系的加工方法。基于本发明的方法制得的多活性组分共包埋稳态化递送体系固态粒子尺寸为20-75μm;其中亲水性活性组分负载率不低于85%,疏水性活性组分负载率不低于39%,疏水性活性组分相较于游离疏水性活性组分的溶解度提高了74倍以上,对疏水性活性组分具有良好的活性保护和靶向递送效果,可以用于设计制备控释功能食品、药品或化妆品。
(3)本发明方法具有操作简单方便、过程安全可控、可实现连续化和低成本绿色生产等特点,且充分利用淀粉资源设计多活性组分共包埋稳态化递送体系,能够提升食品营养品质,实现个性化和营养精准食品的制造。所得产品不仅适用于个性化精准营养食品的创制开发,还能应用于功能食品、医药、化妆品等多个领域。
