Description
技术领域
本发明涉及一种食品防腐剂及其制备方法，尤其是一种天然食品防腐剂及其制备方法。
背景技术
食品防腐剂可以有效地解决食品在加工、储存过程中因微生物“侵袭”而变质的问题，使食品在一般的自然环境中具有一定的保存期；由毒性较高向毒性更低、更安全方向发展。人类进步的核心是健康、和谐。随着人们对健康要求的提高，食品的安全标准也越来越严，由化学合成食品防腐剂向天然食品防腐剂方向发展。鉴于化学合成食品防腐剂的安全性和其他缺陷，人类正在探索更安全、更方便使用的天然食品防腐剂。如微生物源的乳酸链球菌素、那他霉素、红曲米素等；动物源的溶菌酶、壳聚糖、鱼精蛋白、蜂胶等；植物源的琼指低聚糖、杜仲素、辛香料、丁香、乌梅提取物等，微生物、动物和植物复合源的R-多糖等。
发明内容
本发明的目的在于提供一种天然食品防腐剂及其制备方法；
本发明的技术方案在是：
这种天然食品防腐剂，由如下重量份原料配方混合构成：
黄芩提取物3～7、壳聚糖1～2、食盐1～2。
这种天然食品防腐剂的制备方法，由如下步骤构成：
①称取一定量的新鲜或干燥的黄芩5份，洗净、切碎；
②将切碎后的黄芩置入多功能提取罐中，加入5倍于黄芩质量的乙酸乙酯，调节提取罐压力为1.5MPa，温度为30～40℃，提取2次，每次2h，合并提取液；
③将提取液静置沉淀24h，取上层收清液依次通过孔径次为通过为60目、100目、200目和400目的多层丝网过滤；
④将过滤液置入真空浓缩罐中，在4℃下进行浓缩，得浸膏；
⑤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剑150目，即得黄芩提取物；
⑥称取原料黄芩提取物、壳聚糖、食盐充分混合，即得以黄芩为原料的天然食品防腐。
本发明的有益效果：
该发明一种天然食品防腐剂及其制备方法；本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，其抑菌的效果明显优于化学食品防腐剂。
本品的优点在于：①从天然药食两用植物黄芩进行提取制备的保鲜剂，安全无毒、符合目前国家倡导的食品安全性；②采用药食两用植物黄芩进行提取，对开发我国的植物资源是极大的促进；③本品的防腐剂与化学合成类防腐剂如苯甲酸、山梨酸在同等浓度条件下，其抑菌效果更明显；④将本品用于食品生产加工，不仅成本低，且防腐保鲜效果好。
具体实施方式
实施例：
制作方法
(1)称取一定量的新鲜或干燥的黄芩5份，洗净、切碎。
(2)将切碎后的黄芩置入多功能提取罐中，加入5倍于黄芩质量的乙酸乙酯，调节提取罐压力为15MPa，温度为30～40℃，提取2次，每次2h，合并提取液。
