酵母是食品。酵母是一种微生物。它和蘑菇一样属于真菌,富含蛋白质、维生素、矿物质和膳食纤维等营养成分。酵母通过消化面粉中的糖类物质产生气体和酒精,使面团蓬松、具备香味,从而做成可口的馒头、包子,这是生物体进行生物发酵的结果。

酵母是单细胞微生物。它属于高等微生物的真菌类。有细胞核、细胞膜、细胞壁、线粒体、相同的酶和代谢途经。酵母无害,容易生长,空气中、土壤中、水中、动物体内都存在酵母。有氧气或者无氧气都能生存。

酵母是兼性厌氧生物,未发现专性厌氧的酵母,在缺乏氧气时,发酵型的酵母通过将糖类转化成为二氧化碳和乙醇(俗称酒精)来获取能量。

正因为酵母具有营养丰富的食品属性特点,它还能被制成营养保健品,比如即食酵母粉、酵母蛋白粉等等;还被开发成营养丰富的食品属性的鲜味物质——酵母抽提物,非常受欢迎。酵母还被应用到动物养殖,替代抗生素使用,促进绿色养殖、健康养殖。

酵母对发酵食品的作用

1、利于消化吸收

适宜消化功能弱的人食用经过发酵的面包、馒头有利于消化吸收,这是因为酵母中的酶能促进营养物质的分解。

因此,身体瘦弱的人、儿童和老年人等消化功能较弱的人,更适合吃这类食物。同样,早餐最好吃面包等发酵面食,因为其中的能量会很快释放出来,让人整个上午都干精神百倍。

2、发酵后热量会变低

发酵时微生物分泌的酶能裂解细胞壁,提高营养素的利用程度。肉和奶等动物性食品,在发酵过程中可将原有的蛋白质进行分解,易于消化吸收。

微生物还能合成一些B族维生素,特别是维生素B12,动物和植物自身都无法合成这一维生素,只有微生物能“生产”。发酵食品一般脂肪含量较低,因为发酵过程中要消耗碳水化合物的能量,是减肥人士的首选健康食品。

酵母究竟是不是和牛奶等一样,属于食品呢?其实法律法规早已有说明。在GB2760-2011的附录中,就专门列举了食品及其分类。而牛奶就划归在这一附录中,酵母也一样,它被划归为到这一附录中,同样属于食品类别,其分类号为16.04 。

按照我国生产许可证编号规则,如属于食品,则其QS证号均为QS+12位阿拉伯数字;如果属于食品添加剂,则其QS证号是采用XK+10位阿拉伯数字组成。从国家管理部门颁发给安琪酵母的QS证号来看,恰恰是食品证号,即QS+12位阿拉伯数字,例如安琪宜昌工厂生产的安琪牌高活性干酵母QS证号号码为:QS420528010005。

回答3:

是一种作料,比如做馒头就需要的,用作发酵。

回答4:

酵母是发酵必须加的,是一种真菌,是食品制作中常用的东西,可以食用的

@安琪酵母:《第一财经》对话俞学锋:酵母是安全的食品 食品安全只是安琪的低线。鲜味剂使用酵母抽提物,可以不在括号里面标注食品添加剂。下一步食品行业的竞争焦点就是追求清洁标签。谁的标签友好、清洁,谁就能赢得更多的消费者
