一种柿子清秘果粒的制备方法,步骤如下:
⑴清洗:将柿子果皮清洗(去掉多余的果肉、杂质);
⑵脱涩:喷淋65-75%的乙醇、3-5%的乙酸、0.8%的谷氨酸钠水溶液,脱涩2天;
⑶熏蒸:沸水蒸汽熏蒸⑶中所述柿子20-30s,迅速蒸发柿子表面残留乙醇;
⑷发酵:加入0.05-0.15%酵母压实,密封条件下厌氧发酵,温度20-35℃,时间3-5天;
⑸干燥:60-70℃脱水,含水量控制在30-40%;
⑹破碎:破碎后平均粒径80-150目,获得皮渣粉末;
⑺皮渣调配:皮渣粉末80-95份、VC0.05-0.5份、柠檬酸0.05-0.5份、盐0.1-0.6份,按照上述原料配比将原料均匀混合,制成匀浆备用;
⑻果胶、琼脂复水预溶:将果胶、琼脂复水,保温备用;
⑼清秘果粒调配:将⑺中所述原浆调配液加入⑻中制备的果胶与琼脂的混合胶浆中,其中果胶与琼脂加入比例为果粒原浆的0.1-2.5%,搅拌0.5-3min;
⑽浇模、干燥:将⑼中所述清秘果粒调配液趁热浇入木制淀粉模盘中,浇模后立即于表面覆盖淀粉,于干燥室内抽湿定型,温度设定25-40℃,干燥20-30h,获得清秘果粒。
而且,在步骤⑺皮渣调配中还加入:白砂糖5-20份、葡萄糖浆2-8份。
而且,在步骤⑺皮渣调配中还加入:木糖醇0.1-0.6份。
而且,所述果胶、琼脂复水预溶的步骤为:在夹层锅中加入一定量的85℃热水,打开蒸汽加热煮沸慢慢搅拌下缓缓加入事先混匀的一定量的果胶,煮至沸腾使果胶完全复水备用,琼脂的预溶是先加25倍冷水浸泡使其膨润1h,以下步骤同上,并且保温备用。
而且,所述柿子果皮的来源如下:
⑴挑选:柿子的成熟度为5~10分熟;
⑵清洗:将⑴中所述柿子用清水清洗除去表面杂质及灰尘;
⑶脱涩:将⑵中所述柿子经传送带均匀通过盛满含有65-75%的乙醇,3-5%的乙酸,0.8%的谷氨酸钠水溶液的清洗槽,于密闭环境,脱涩2天;
⑷挤压分离:将⑶中所述柿子挤压破碎分离果蒂、果皮与果肉,剔除果蒂,经40目滤布过滤,取皮渣。
而且,所述柿子果皮的来源于柿子果汁、果酒、柿子饼、原浆或罐头加工产生过程产生的柿子果皮。
而且,所述清秘果粒的后处理过程如下:
⑾筛选果粒:将⑽中所述干燥成型的清秘果粒用筛选机分离清秘果粒与多余淀粉;
⑿吹粉:将⑾中所述筛选好的清秘果粒置吹粉机中,通过压缩空气将果粒表面残余淀粉彻底吹净;
⒀成品包装:对⑿中所述柿子清秘果粒进行枕式充氮包装。
一种柿子清秘果粒,由上述的方法制备获得。
本发明的优点和积极效果如下:
1、本发明以柿子加工类食品(如柿饼、原味沙司等)的皮渣为原料,皮渣纤维具有对肠道的“清洗”作用,经脱涩去除鞣酸,与白砂糖及葡萄糖浆良好融合后,加以食品级果胶、琼脂利于成型,成型后的果粒适用于各类人群,尤其是便秘人群,同时柿子清秘果粒没有相关产品问世。
2、本果粒制备过程中不经过熬煮,很好的保留了新鲜柿子所具有的风味、组织及营养,制备过程均采用经济、节能、简易的操作,提高了柿子的利用率。
3、本果粒制备过程中柿子进行脱涩,然后在脱涩又加入经过反涩程序,保证了柿子皮渣的口味。
4、本果粒制备过程中的皮渣经胶体磨研磨,使皮渣的颗粒变小,适合消化,提高口感。
具体实施案例
下面结合实施例,对本发明进一步说明,下述实施例是说明性的,不是限定性的,不能以下述实施例来限定本发明的保护范围。
实施例1
一种柿子清秘果粒的制备方法,步骤如下:
⑴挑选:柿子的成熟度为5~10分熟,其中最佳值为8分熟;
⑵清洗:将⑴中所述柿子用清水清洗除去表面杂质及灰尘;
⑶脱涩:比如,将⑵中所述柿子经传送带均匀通过盛满含有65%的乙醇,3%的乙酸,0.8%的谷氨酸钠水溶液的清洗槽,并平码于带孔隙的塑料筐内,层层叠放,并迅速用塑料大帐包裹码放好的柿子,形成密闭环境,脱涩2天;
⑷挤压分离:将⑶中所述柿子挤压破碎分离果蒂、果皮与果肉,剔除果蒂,经40目滤布过滤,取皮渣(皮渣中含果肉20%-30%);

⒀成品包装:对⑿中所述柿子清秘果粒进行枕式充氮包装,每包125g,并放小包干燥剂,防止果粒回潮。
实施例2
一种柿子清秘果粒的制备方法,
⑴清洗:将柿子果皮清洗(去掉多余的果肉、杂质)
⑵脱涩:喷淋65-75%的乙醇、3-5%的乙酸、0.8%的谷氨酸钠水溶液,脱涩2天;重复脱涩后,彻底清除柿子皮的涩味;
⑶熏蒸:沸水蒸汽熏蒸⑶中所述柿子20-30s,迅速蒸发柿子表面残留乙醇;
⑷发酵:加入0.05-0.15%酵母(安琪酵母)压实,密封条件下厌氧发酵,温度20-35℃,时间3-5天;经过发酵后长纤维变成短纤维,有效改善柿子皮的口感。
⑸干燥:60-70℃脱水,含水量控制在30-40%;
⑹破碎:破碎后平均粒径80-150目,获得皮渣粉末;
⑺皮渣调配:皮渣粉末80-95份、VC0.05-0.5份、柠檬酸0.05-0.5份、盐0.1-0.6份、白砂糖10份、葡萄糖浆8份,按照上述原料配比将原料均匀混合,制成匀浆备用;
⑻果胶、琼脂复水预溶:在夹层锅中加入一定量的85℃热水,打开蒸汽加热煮沸慢慢搅拌下缓缓加入事先混匀的一定量的果胶,煮至沸腾使果胶完全复水备用,琼脂的预溶是先加25倍冷水浸泡使其膨润1h,以下步骤同上,并且保温备用;
⑼清秘果粒调配:将⑺中所述原浆调配液加入⑻中制备的果胶与琼脂的混合胶浆中,其中果胶与琼脂加入比例为果粒原浆的0.1-2.5%,强力搅拌0.5-3min;果胶:琼脂=1:1;
⑽浇模、干燥:将⑼中清秘果粒调配液趁热浇入木制淀粉模盘中,浇模后立即于表面覆盖淀粉,于干燥室内抽湿定型,温度设定25-40℃,其中最佳值为35℃,干燥20-30h,使果粒获得较适中的软硬度与弹性,并保证不粘牙;
⑾筛选果粒:将⑽中所述干燥成型的清秘果粒用筛选机分离清秘果粒与多余淀粉;
⑿吹粉:将⑾中所述筛选好的清秘果粒置吹粉机中,通过压缩空气将果粒表面残余淀粉彻底吹净;
⒀成品包装:对⑿中所述柿子清秘果粒进行枕式充氮包装,每包125g,并放小包干燥剂,防止果粒回潮。
本实施例加糖后有效改善口感,增加糖度。
实施例3
其余步骤与实施例1相同,在步骤⑺中加入木糖醇0.6份,该成分中含有木糖醇,特别适合糖尿病人实用。
