Description
技术领域
本发明涉及一种食品天然防腐剂,特别是涉及一种含有纳他霉素的天然保鲜防腐剂,属于食品添加剂领域。
背景技术
为了使食品能够长久保存,防止食品的腐败变质,同时为了保证食品的品质和口感,目前在各类食品的贮藏存放时或制作加工过程中往往需加添加食品保鲜剂防腐剂。目前市场上较为常见的保鲜剂有山梨酸钾、乳酸链球菌素和乳酸钠三大主要种类,这些保鲜剂有的在初始菌数量较大时更加容易变质,有的只能延长保存期3-5天,有的成本高,增加产品费用,综合效果都不够理想。常见的防腐剂为苯甲酸、山梨酸及其盐类、对羟基苯甲酸酯,价格较低,但添加后会对食品的口感及人们的身体健康产生不良影响,而且实际防腐效果还受到其他因素的影响。目前,食品添加剂正在向天然、营养的趋势发展,我国的植物资源又十分丰富从植物中寻找和提取天然食品添加剂成为当前食品添加剂研究开发的主流。因此,开发高效、广谱、安全稳定且便宜的天然保鲜防腐剂具有非常重要的意义。
针对现有防腐剂、保鲜剂所存在的若干缺陷,不少单位和个人提出了一些新的改进方案。如卢锦荣曾于2008年12月12日就提出过一件名为“一种用于水果的天然食品保鲜剂及其制备方法”的发明专利申请,公布了一种用于水果的天然食品保鲜剂,其技术方案主要包含有芦荟和连翘叶提取液,质量比为:30-50∶7-13。该技术方案的特点是将该保鲜剂用于水果类的保鲜实验,具有显著的保鲜效果,可实现对水果类的长期保存。而且该保鲜剂为纯天然植物提取制备,保鲜后的水果安全无残毒、品质好、保鲜期长,有利于水果类运输、销售、保藏成本的降低。与此同时,黄驰波也于2008年12月12日提出过名为“以芦荟为原料的天然食品防腐剂及其制备方法”的发明专利申请(专利申请号为200810219942.3),其公布了一种以芦荟为原料的天然食品防腐剂及其制备方法,由芦荟提取物、葡萄糖和食盐为原料混合而成,所述原料的重量比为:芦荟提取物:5-15、葡萄糖:1-2、食盐:1-2。所述的芦荟提取物是芦荟提取液通过干燥制成的粉剂。该技术方案所制得的天然食品防腐剂具有广谱抑菌的功效,对各类细菌、酵母菌、霉菌有较强的抑菌效果,其抑菌效果明显优于化学食品防腐剂。
诸如此类的现有技术还有许多,但总体来看,这些技术方案不是偏重于延长保存时间就是过于强调口感保鲜,综合效果均不够理想。特别是各类研究表明,自然界天然植物中存在许多生理活性物质,如果对这些天然植物进行综合提取并配制成组合,制作天然防腐保鲜剂,既天然又安全。纳他霉素,是一种重要的多烯类抗菌素,其作为一种天然的食品防腐剂已被批准应用于某些乳制品、肉类、水果、饮料等许多食品工业中,如能将其与相关植物源防腐剂相结合,则应有非常好的应用前景。
发明内容
本发明要解决的技术问题是克服现有天然防腐剂难以有效保持鲜度和现有天然保鲜剂难以有效延长保存时间的限制,通过添加纳他霉素和其他植物的有效配伍组合提供一种既能大幅延长食品保存时间又可以大幅提升食品保存鲜度的天然食品添加剂。
本发明解决上述技术问题所采取的技术方案是:一种含有纳他霉素的天然保鲜防腐剂,由以下重量配比的原料制作而成:纳他霉素10~20份、黄芩提取液10~20份、连翘叶提取液3~5份、大蒜素2~3份。
本发明的优选方案是:纳他霉素12份、黄芩提取液12份、连翘叶提取液3份、大蒜素2份。
本发明的优选方案是:纳他霉素12份、黄芩提取液12份、连翘叶提取液3份、大蒜素2份、乳酸链球菌素1~2份。
本发明的制备方法是:将连翘叶提取液洗净、切碎后置入多功能提取罐中,加入4倍于连翘叶提取液质量的水,调节提取罐压力为1.5MPa、温度为30~33℃,提取3次,每次1.5小时,获得混合提取液,再将提取液静置沉淀24小时,取上层清液依次通过孔径为100目、200目和400目的丝网进行三重过滤,接着再向滤液中加入规定重量的纳他霉素、黄芩提取液、大蒜素、乳酸链球菌素,然后再置入真空浓缩罐中,在0℃下进行浓缩得浸膏,最后将浸膏通过干燥塔进行干燥,干燥后通过万能粉碎机进行粉碎到100目即可。
本发明的优点在于:(1)本发明的主要原料如连翘叶提取液以及大蒜素均来自天然植物,所选用的纳他霉素安全无毒,符合目前国家倡导的食品安全性;(2)采用连翘叶提取液以及大蒜素提取制备保鲜防腐剂,既充分运用了现在植物资源,而且所制得防腐保鲜剂成本较低,相对于同等功效的普通保鲜剂和防腐剂,本发明的综合成本可减少60%以上,便于大范围推广;(3)保鲜效果较好,纳他霉素是白色、无气味、无味道的粉状物,故对产品的口感物性无任何影响,而且纳他霉素对真菌极为敏感,微量使用即可起作用,作为防腐剂的用量仅为山梨酸钾的1/50—1/100,少许使用即可使食品保鲜期延长1倍以上;(4)防腐效果较佳,连翘叶提取液则能抑制和消灭病原体的发育繁殖,大蒜素作为本发明的增效剂,与纳他霉素和连翘叶提取液相互补充,可使本发明具有明显的防腐效果。
具体实施方式
下面结合实施例对本发明的原理及优点作进一步阐述。
实施例1:按规定比例称取0.3KG连翘叶提取液洗净、切碎后置入多功能提取罐中,加入4倍于连翘叶提取液质量的去离子水,调节提取罐压力为1.5MPa、温度为30℃,提取3次,每次1.5小时,获得连翘叶提取液提取液,再将提取液静置沉淀24小时,取上层清液依次通过孔径为100目、200目和400目的丝网进行三次过滤,接着再向滤液中加入1KG纳他霉素、1KG黄芩提取液、0.2KG大蒜素,然后再置入真空浓缩罐中,在0℃下进行浓缩得浸膏,最后将浸膏通过干燥塔进行干燥,干燥后通过万能粉碎机进行粉碎到100目即可。
实施例2:按规定比例称取0.5KG连翘叶提取液洗净、切碎后置入多功能提取罐中,加入4倍于连翘叶提取液质量的去离子水,调节提取罐压力为1.5MPa、温度为33℃,提取3次,每次1.5小时,获得连翘叶提取液提取液,再将提取液静置沉淀24小时,取上层清液依次通过孔径为100目、200目和400目的丝网进行三次过滤,接着再向滤液中加入2KG纳他霉素、2KG黄芩提取液、0.3KG大蒜素、0.2KG乳酸链球菌素,然后再置入真空浓缩罐中,在0℃下进行浓缩得浸膏,最后将浸膏通过干燥塔进行干燥,干燥后通过万能粉碎机进行粉碎到100目即可。
实施例3:实施例2:按规定比例称取0.3KG连翘叶提取液洗净、切碎后置入多功能提取罐中,加入4倍于连翘叶提取液质量的去离子水,调节提取罐压力为1.5MPa、温度为35℃,提取3次,每次1.5小时,获得连翘叶提取液,再将提取液静置沉淀18小时,取上层清液依次通过孔径为100目、200目和400目的丝网进行三次过滤,接着再向滤液中加入1.2KG纳他霉素、1.2KG黄芩提取液、0.2KG大蒜素、0.2KG乳酸链球菌素,然后再置入真空浓缩罐中,在0℃下进行浓缩得浸膏,最后将浸膏通过干燥塔进行干燥,干燥后通过万能粉碎机进行粉碎到100目即可。经综合比较,在同等浓度条件,本实施例3所制得的天然保鲜防腐剂3的保鲜防腐效果更好。
