Description
技术领域
本发明属于食品领域，具体涉及一种营养全面、低敏性的婴幼儿营养米粉的生产方法。
背景技术
婴幼儿营养米粉是一种常见的婴幼儿辅食。目前市场上的婴幼儿米粉并不少见，大部分添加有乳粉、蛋粉或大豆粉等作为蛋白质补充剂。但婴幼儿极易过敏，有报道表明与早期接触牛奶、鸡蛋、花生和其他主要致敏食物有关。24月龄以内婴儿以IgE介导的食物过敏发病率约为6%～8%，远高于成人食物过敏发病率1%～2%。
发明内容
本发明的目的在于提供一种易消化的营养全面、低敏性的婴幼儿营养米粉的生产方法。
为了实现上述的目的，本发明采用了如下技术方案：
一种营养全面、低敏性的婴幼儿营养米粉，其特征在于，首先采用碱提法提取大米蛋白粉；然后以梗米、黑米、核桃仁、燕麦和玉米为原料，经清洗、浸泡、胶体磨磨浆，得到浆料；最后将浆料酶解，复配，均质，喷雾干燥，干混，包装，得到一种营养全面、低敏性的婴幼儿营养米粉。
所述的营养全面、低敏性的婴幼儿营养米粉，其特征在于，其由如下步骤制备而成：
（1）将籼米、糯米和梗米以1：0.2-0.25：0.35-0.4的质量比混合，粉碎后过80-100目筛；将其加入到8-10倍重量份的氢氧化钠水溶液中，35-40℃恒温浸提2-3次，每次浸提2-3h，合并滤液；将滤液的pH值调节至4.2-4.6，静置，离心分离，得到蛋白凝胶；将蛋白凝胶加入到5-6倍重量份的去离子水中，调节体系pH至中性，蒸汽灭菌，闪蒸脱水，喷雾干燥，得到大米蛋白粉；
（2）将梗米、黑米、核桃仁、燕麦和玉米混合后，通过洗米机洗米，将水和杂粮混合，经过高压旋流离心，将大米中混合的稻壳、杂草、泥沙、小石子等杂质，各自分流排除，得到干净的大米；
（3）将清洗过的杂粮以1：2-2.2的料液比加水混合，通过物料输送泵输送到浸泡罐内进行浸泡，浸泡水温22-25℃，搅拌速率25-35r/min，浸泡时间1.5-2h，采用胶体磨进行磨浆，得到浆料；
（4）向浆料中加入加0.0002-0.0003倍重量份的α-淀粉酶，酶解温度为55-60℃，酶解时间为20-25min，得酶解浆料；
（5）向酶解浆料中加入低聚果糖、鱼粉、胡萝卜粉、青菜粉和营养强化剂，混匀，然后进行高压均质，均质压力控制在140-150MPa，均质时间20-25min，得到均质浆料；将均质浆料喷雾干燥，干燥温度为140-150℃，干燥时间15-20s，得到米粉半成品；
（6）将米粉半成品、大米蛋白粉和双歧杆菌益生菌粉以1：0.05-0.06：0.02-0.03的质量比混合，包装，得到营养全面、低敏性的婴幼儿营养米粉。
所述的营养全面、低敏性的婴幼儿营养米粉的生产方法，其特征在于，步骤（1）中氢氧化钠水溶液的浓度为0.04-0.05mol/L。
所述的营养全面、低敏性的婴幼儿营养米粉的生产方法，其特征在于，步骤（2）中梗米、黑米、核桃仁、燕麦和玉米的质量比为1：0.18-0.22：0.1-0.12：0.12-0.15：0.15-0.18。
所述的营养全面、低敏性的婴幼儿营养米粉的生产方法，其特征在于，步骤（5）中酶解浆料、低聚果糖、鱼粉、胡萝卜粉、青菜粉和营养强化剂的质量比为1：0.06-0.08：0.05-0.06：0.08-0.1：0.06-0.08：0.04-0.05。
所述的营养全面、低敏性的婴幼儿营养米粉的生产方法，其特征在于，步骤（5）中营养强化剂由维生素B120-25份、维生素B225-30份、叶酸4-5份、铁0.4-0.5份、锌0.2-0.3份、钙0.3-0.4份、硒0.1-0.2份组成。
本发明的有益效果为：
本发明通过碱提法提取大米蛋白，以大米蛋白作为蛋白质补充剂，相比与乳粉、蛋粉或大豆粉等蛋白质补充剂，大米蛋白是公认的低致敏性蛋白，更加适合婴幼儿食用，绿色安全。本发明采用α-淀粉酶水解大米淀粉，将部分大米淀粉降解为麦芽糖、低聚糖、糊精等可溶性物质，改善口感，提高营养米粉在肠道内的消化率，改善营养米粉品质。本发明添加了双歧杆菌益生菌粉，可以激活人体自身免疫系统产生免疫物质，防止细菌病毒感染，对于经常感冒发烧等免疫力低下的婴幼儿，食用之后，其免疫系统能更好的发育，抵抗力越来越强。本发明的婴幼儿营养米粉，细腻，冲调性好，营养全面，低敏性，更适合婴幼儿食用，更易消化吸收。
具体实施方式
本实施例的营养全面、低敏性的婴幼儿营养米粉，其由如下步骤制备而成：
（1）将籼米、糯米和梗米以1：0.25：0.4的质量比混合，粉碎后过80目筛；将其加入到10倍重量份的氢氧化钠水溶液中，40℃恒温浸提3次，每次浸提2-3h，合并滤液；将滤液的pH值调节至4.5，静置，离心分离，得到蛋白凝胶；将蛋白凝胶加入到6倍重量份的去离子水中，调节体系pH至中性，蒸汽灭菌，闪蒸脱水，喷雾干燥，得到大米蛋白粉；
（2）将梗米、黑米、核桃仁、燕麦和玉米混合后，通过洗米机洗米，将水和杂粮混合，经过高压旋流离心，将大米中混合的稻壳、杂草、泥沙、小石子等杂质，各自分流排除，得到干净的大米；
