Description

说 明 书 一种营养强化的复合米及其制备方法 技术领域
本发明涉及一种复合米及其制备方法, 特别涉及一种营养强化的复合米及其制备方 法, 属于食品加工领域。 背景技术
占世界人口 2/3以上的亚洲、 中东以及拉丁美洲的居民以谷物作为日常生活的主食, 满足其日常卡路里摄入和营养素的摄入。 然而谷物中含有的维生素等营养素在经过碾磨 后, 仅能保留一小部分, 而大部分的维生素等营养素随着外壳和胚乳在碾磨过程中被一 同被除去。
所以向营养素大量丧失的谷物中添加合理的维生素、 微量元素、 必需氨基酸等营养 素, 综合提高谷物的食用营养价值, 满足以谷物为主食的居民的维生素等营养素的需求, 从而预防疾病保持健康, 已成一个世界性的课题。 然而如何通过低价、 简单且有效的方 法来强化谷物中的营养素含量, 目前仍未有较好的技术方案。
世界各国对营养强化的谷物, 尤其是米的研究很多, 主要有籽粒预混合工艺、 粉末 预混合工艺等较为简单的生产方法, 后来发展的人造强化米工艺、 酸预蒸法工艺、 直接 浸吸法工艺和涂膜法工艺等比较成熟的生产方法, 以及近年来出现的膨化微孔一固化一 浸吸营养剂一复膜的生产方法。
法国专利公开文本 US1530248公开了一种营养强化的人造谷粒。该人造谷粒由粗小 麦粉或面粉的面团及维生素制备,采用挤压机挤压面团成糊状结构,然后切成小块,进行 干燥。然而, 根据该方法制备的谷粒在烹煮过程中稳定性很差, 极易碎裂, 从而使营养素 丧失。 同样的问题也存在于中国专利 200510039229.7中。
美国专利 US620762公开了一种制备富营养的人造米的方。 该方法将米粉、 营养物 以及粘合剂混合, 然后蒸煮混合物使其中的淀粉半胶凝化, 最后制粒得到米粒。然而, 该 方法的蒸煮处理的时间较长和温度较高,会导致敏感的微量营养物性能丧失以及米粒味道 的不良。
美国专利 US5609896公开了一种采用挤出技术来制备富营养的人造米的方法。 该 方法通过加入特定添加剂, 如热稳定剂、粘合剂、交联剂等, 来克服了米粒稳定性较差以 及维生素流失的问题。然而该方法的生产过程较为复杂、实施困难、成品率低并且成本较 高。
PCT国际申请 PCT/EP2004/012710公开了一种制备富营养的复原米的方法。 该方 法将粉碎的米基质、微量营养物、乳化剂和水混合,然后将混合物加热并挤出成型进行切 割, 得到颗粒。该方法在挤压前添加了一个预加热处理步骤, 并同样的使用了粘合剂。然 而该预加热处理过程无法对混合物进行充分均匀的加热,并且制得的产品较软并且容易破 碎。
同样的 PCT 国际申请 PCT/US96/02708、 PCT/US95/00682、 美国专利 US20070054029. US6139898、 US5403606、 US4886675、 US3620762、 英国专利 GB1225070, 加拿大专利 CA2558700、 以及澳大利亚专利 AU1808883中都不同程度的 存在以上所述的问题和缺陷。 发明内容
本发明的一个目的在于提供一种经过营养强化的复合米以及制造该复合米的方法, 以弥补现有技术的不足。
本发明涉及的一种营养强化的复合米的制备方法, 具体包括如下步骤:
以黑米、 粳米、 籼米、 糯米作为原材料和大米一起进行预筛选, 筛去杂质, 然后对 原材料和大米除尘并随后粉碎。 对原材料和大米的除尘进一步包括静电除尘和高压除尘, 对原材料和大米的粉碎采用多级粉碎。分别采用检查筛筛选粉碎后的颗粒,对尺寸不合格 的颗粒分别回收并重新进行多级粉碎处理, 得到原材料粉末和米粉。
将粉碎后的 18〜42重量份原材料粉末与 8〜22重量份水预混合,并加入 1〜2重量 份乳化剂搅拌,加热得到的混合物至 60〜80°C,并向其中添加的 80〜90°C高温水蒸气和
60〜70°C的低温水蒸气, 以调节混合物的温度为 70〜80°C,预混合 0.5〜2.4小时得到预 混合物;
向所得的预混合物中加入 18〜42重量份米粉、 8〜22重量份水, 加热得到的混合 物至 60〜80°C, 并向其中添加的 80〜90°C高温水蒸气和 60〜70°C的低温水蒸气, 以调 节混合物的温度为 70〜80°C。 向混合物中内添加 1〜2重量份纤维素、 1〜2重量份热稳 定剂、 1〜2重量份的营养素以及 1〜2重量份交联剂,在 70〜80Ό的混合温度下混合 1〜 6小时, 得到混合物。
所述的营养素为维生素 、 维生素 Β1、 维生素 Β2、 维生素 Β6、 叶酸、 烟酸、 维生 素 Β12、 维生素 C、 维生素 E、 维生素 K、 微量元素、 核黄素、 VA醋酸脂、 硫胺素、 葡 萄糖酸锌、 葡萄糖酸钙、 乳酸钙中的一种或多种。
将所得的混合物注入挤压机,在 80〜100°C进行挤压热处理 0.5〜5分钟,混合物经 挤压机出口处的模孔挤出, 并被旋转切割刀切割得到粒径为 2〜6mm、 长度为 7〜19mm 的颗粒。 对切割后的颗粒涂敷一层可食用油脂类物质, 然后对步骤 3 中产生的碎料回收 并重新挤压成型。
将所得的颗粒进行高温干燥, 干燥温度为 60〜80°C, 干燥时间 30〜210秒, 干燥 后含水量为 20〜25%。
然后对所得的颗粒进行多级低温干燥,干燥温度依次为 50〜60°C、 40〜50°C、 30〜
40Ό以及 20〜30°C, 干燥时间皆为 30分钟至 10小时, 干燥后的含水量依次为.16〜21 %、 14〜19%、 12〜17%以及 10〜15%。
在所得的颗粒上涂敷一层可食用油脂, 在温度为 15〜25°C、 湿度为 10〜15%的环 境下恒温恒湿冷却 10〜60小时, 得到产品。
对产品进行色选检验, 回收次品并将其返回重新粉碎。
对合格的产品进行打磨并采用可食用色素, 对其表面进行喷涂染色并干燥。
本发明还涉及一种釆用上述方法制备得到的营养强化的复合米。 所述复合米包含 18〜42重量份原材料粉末、 18〜42重量份米粉, 1〜2重量份纤维素、 1〜2重量份热稳 定剂、 1〜2重量份的营养素以及 1〜2重量份交联剂,所述复合米的含水量为 10〜15 %。 所述的营养素为维生素 、维生素 B1、维生素 B2、维生素 B6、叶酸、烟酸、维生素 B12、 维生素 C、 维生素 E、 维生素 K、 微量元素、 核黄素、 VA醋酸脂、 硫胺素、 葡萄糖酸锌、 乳酸钙中的一种或多种。
本发明的营养强化的复合米具有与天然大米相同或相近的外形, 并且具有与天然大 米相同或相近的煮熟时间。
所述的乳化剂的加入便于粉碎后的原材料粉末、 米粉与水的混合, 并避免最后制得 的复合米颗粒表面开裂。
所述的纤维素为混合物提供了一个起到支撑作用的纤维骨架, 从而使得最后制得的 复合米颗粒中含有具有一定支撑力的纤维骨架,以保证复合米颗粒的硬度与天然大米的硬 度相近,并避免复合米由于过于柔软而在其后的干燥等流程中变形或破损,从而减小废品 率。 所述的热稳定剂用于保护其后添加至混合物中的各种营养素, 以避免上述营养素在 制备过程中因温度过高而失活或被破坏, 从而保证了复合米中营养素的含量。
所述的营养素可以根据具体的需要及配方, 自由选取。 上述营养素的范围并不仅限 于权利要求和说明书中所列举的营养素。 , 所述原材料粉末、 米粉和水的混合物在加热条件下逐渐半胶凝化, 加入所述的 联 剂,便于促使淀粉分子间的交联反应, 从而使得制得的复合米具有良好的弹性、内部粘结 力、表面粘结力, 从而避免复合米颗粒破碎、表面开裂。 同时交联剂的加入可以减少为了 促使半胶凝化的加热时间, 避免营养素因加热时间较长而失活或被破坏。
在挤出后切割得到的颗粒外表面涂敷一层可食用油脂类物质的目的在于避免该颗粒 在随后的干燥过程中因水分散失而可能带来的复合米表面开裂。
所述的高温干燥的目的在于使得颗粒的含水量快速降低, 但该干燥时间较短以避免 水分快速散失所导致的复合米表面开裂。
采用所述的多级低温干燥的目的在于,逐级的使复合米颗粒的水分缓慢温和的散失, 避免颗粒外表面水分散失快而内部水分散失慢所带来的干燥不充分以及颗粒外表面开裂 等问题。
在干燥后的颗粒外表面涂敷一层可食用油脂类物质的目的在于进一步避免颗粒破损 及开裂,而其后采用的所述的长时间恒温恒湿处理可以使得复合米的含水量稳定在一定范 围内,并逐渐使得复合米外表面涂敷的物质形成一层保护膜。经过恒温恒湿处理的复合米 的稳定性较好。
可选择地对色选后地复合米颗粒进行进一步地后处理, 即打磨和染色, 以使得复合 米在外形上更加接近与天然大米。
所有制备过程中地废弃物料都能得以回收, 并相应地重新进行处理, 故该制备流程 中地物料损失极低。 附图说明

6、 流程 9中采用的恒温恒湿冷却的温度为 15Ό、 湿度为 10%、 时间为 10小时。 经过上述制备流程得到的营养强化的复合米, 包含 40重量份原材料粉末、 20重 份米粉, 2重量份纤维素、 1重量份热稳定剂、 1重量份的营养素以及 2重量份交联剂, 所述复合米的含水量为 10%。
所述的纤维素、 热稳定剂、 营养素及交联剂的组成如上所述。 本发明中采用了多种添加剂, 其作用如下:
所述的乳化剂的加入便于粉碎后的原材料粉末、 米粉与水的混合, 并避免最后制俨守 的复合米颗粒表面开裂。
所述的纤维素为混合物提供了一个起到支撑作用的纤维骨架, 从而使得最后制得的 复合米颗粒中含有具有一定支撑力的纤维骨架,以保证复合米颗粒的硬度与天然大米的硬 度相近,并避免复合米由于过于柔软而在其后的干燥等流程中变形或破损,从而减小废品 所述的热稳定剂用于保护其后添加至混合物中的各种营养素, 以避免上述 制备过程中因温度过高而失活或被破坏, 从而保证了复合米中营养素的含量。
所述的营养素可以根据具体的需要及配方, 自由选取。 上述营养素的范围并不仅限 于权利要求和说明书中所列举的营养素。 所述原材料粉末、 米粉和水的混合物在加热条件下逐渐半胶凝化, 加入所述的交联 剂,便于促使淀粉分子间的交联反应,从而使得制得的复合米具有良好的弹性、内部粘结 力、表面粘结力, 从而避免复合米颗粒破碎、表面开裂。 同时交联剂的加入可以减少为了 促使半胶凝化的加热时间, 避免营养素因加热时间较长而失活或被破坏。
在挤出后切割得到的颗粒外表面涂敷一层可食用油脂类物质的目的在于避免该颗粒 在随后的干燥过程中因水分散失而可能带来的复合米表面开裂。
所述的高温干燥的目的在于使得颗粒的含水量快速降低, 但该干燥时间较短以避免 水分快速散失所导致的复合米表面开裂。
采用所述的多级低温干燥的目的在于,逐级的使复合米颗粒的水分缓慢温和的散失, 避免颗粒外表面水分散失快而内部水分散失慢所带来的干燥不充分以及颗粒外表面开裂 等问题。
在干燥后的颗粒外表面涂敷一层可食用油脂类物质的目的在于进一步避免颗粒破损 及开裂,而其后采用的所述的长时间恒温恒湿处理可以使得复合米的含水量稳定在一定范 围内,并逐渐使得复合米外表面涂敷的物质形成一层保护膜。经过恒温恒湿处理的复合米 的稳定性较好。
可选择地对色选后地复合米颗粒进行进一步地后处理, 即打磨和染色, 以使得复合 米在外形上更加接近与天然大米。
所有制备过程中地废弃物料都能得以回收, 并相应地重新进行处理, 故该制备流程 中地物料损失极低。
综上, 本发明的技术优势在于制备得到的营养强化的复合米不仅具有与天然大米相 似或相近的外形, 而且具有与天然大米相似或相近的煮熟时间和硬度, 并且不容易破损, 并且本发明的制备方法工艺流程简单, 产率高
