Description

一种低糖火龙果皮果脯加工方法
技术领域
本发明属于食品加工技术领域,尤其涉及一种低糖火龙果皮果脯加工方法。
背景技术
火龙果(Pitaya)又称为红龙果,为仙人掌科(Cactaceae)量天尺属植物。果皮颜色为紫红色,艳丽迷人,而果肉颜色有白、黄、红等几个不同品种。火龙果在我国台湾栽培较多,已有十多年的历史,目前已在海南、广西、广东、福建等省区兴起,是热带、亚热带的名优水果之一,火龙果具有非常高的营养价值,含有丰富的花青苷、植物白蛋白、VC及膳食纤维,已经成为优良的绿色保健食品。
作为水果食用时,火龙果的皮经常当做废物被抛弃掉,但果皮中含有大量的膳食纤维、花青素、黄酮、可溶性还原糖等成分。现在水果加工厂加工火龙果只使用果肉部分,而火龙果的外皮则作为废弃物处置,因而将火龙果果皮加工成果脯,可以提高副产物的利用率。但是现在加工火龙果皮普遍采用糖液煮制经过硬化的火龙果皮,通过在糖液中加酸加热的方式提高还原糖含量,防止果脯返砂,由于火龙果皮中的花青素、黄酮等都不耐高温,糖液煮制的方法会严重破坏这些营养成分,降低了产品的营养价值。
发明内容
本发明针对以上技术问题,提供了一种低糖火龙果皮果脯加工方法。
具体是通过以下技术方案来实现的:
一种低糖火龙果皮果脯加工方法,包括以下制备步骤:
1)清洗:火龙果皮上清洗,削除鳞片,切成条备用;
2)消毒:将步骤1)得到的果皮条浸泡消毒液中,消毒;
3)浸糖:将步骤2)消毒后的果皮浸泡于复合糖液中;
4)干燥:将浸糖后的果皮干燥,封装,既得。
进一步,所述的消毒液,是质量浓度为100-200mg/L的二氧化氯溶液。
进一步,所述的消毒,是将果皮浸泡于消毒液中30-90s。
进一步,所述的复合糖液,含有65%高麦芽糖浆、其质量分数为10-20%,食用甘油,其质量分数为0.5-0.8%,苹果酸、质量分数为0.2-0.4%,糖度为25-35°BX。
进一步,所述的复合糖液,含有65%高麦芽糖浆、其质量分数为10%,食用甘油,其质量分数为0.8%,苹果酸、质量分数为0.4%,糖度为30°BX。
进一步,所述的浸糖,是在复合糖液中浸泡20-27h。
进一步,所述的干燥,是在30-40℃、真空干燥8-16h。
有益效果,本发明制备的火龙果皮果脯,通过采用一定的复合糖液浸糖,真空干燥,保证了产品的水分含量在25%左右,产品具有较好的外型和口感,使得制备的果脯甜味稳定,干燥受热时不易发生美拉德反应,对延长产品的货架期效果明显,同时抑制火龙果皮中单宁异性增生,达到护色、保鲜、增重效果,延长保质期。制备的火龙果皮果脯,色泽紫红,均匀一致,明有光泽,饱满度好,不粘手,无破裂,透甜酸度适中,无异味,软硬适中,有嚼劲。
综上所述,本发明制备的火龙果皮果脯,与现有技术相比,具有以下有点:
1)制备步骤简单,没有进行硬化护色、蒸煮或糖液煮制的工序,通过低温短时浸糖处理,最大限度的减少火龙果皮中营养物质的破坏损失,保留火龙果皮的营养及色泽。
2)制备的成品中,低糖火龙果皮果脯水分23.9%;总糖43.2%;还原糖29%;总酸0.31%,保证了火龙果皮果脯口感较优。
