食品行業(yè)隨著人們的消費(fèi)水平水漲船高,酵母制品亦出現(xiàn)卓越的發(fā)展,且總體發(fā)展勢頭朝向高檔化、簡便化、多元化、復(fù)合化和營養(yǎng)化?,F(xiàn)已經(jīng)從原來較為簡單的饅頭、面條和酒等發(fā)展成為一個品種眾多的大家族,搖身一變成為廣大吃貨生活中不可替代的美食伴侶。
酵母菌作為核心在其制品中起到了口感和芳香的作用,酵母菌本身都是天然的,為了讓食品的品質(zhì)更好,并且方便批量制作,酵母工廠就從于自然界當(dāng)中的酵種挑選出優(yōu)秀酵母,人工培育后制作可食用酵母添加劑;這其中就涉及到——酵母菌的研磨。
酵母研磨-凈信研磨儀是專業(yè)的能手
酵母菌是一種可食用的豐富的單細(xì)胞微生物,大多數(shù)酵母菌的菌落特征與細(xì)菌相似,但比細(xì)菌菌落大而厚,菌落表面光滑、濕潤、粘稠,容易挑起;酵母菌廣泛分布于整個自然界,在有氧和無氧條件下,都能夠存活,主要生長在偏酸性潮濕的含糖環(huán)境中。
酵母菌是一種天然發(fā)酵劑,酵母能將糖發(fā)酵成乙醇和二氧化碳;人們很早就開始將酵母菌應(yīng)用于食品生產(chǎn)中。在面食和釀造工藝制作中,使面團(tuán)膨脹變得松軟,使酒、醬等制品變得香醇。
Tissuelyser多樣品組織研磨儀,能產(chǎn)生上下震蕩、旋渦震蕩,使樣品高速高效的相互撞擊,組織研磨儀一次可同時處理多個樣品。對于難處理的巖石、金屬、骨骼、牙齒、頑固的細(xì)菌、真菌細(xì)胞壁,甚至孢子體的研磨效率非常高,且整個研磨過程用時短,并同時保留生物分子(DNA、RNA、蛋白質(zhì))和藥物分子的完整性。
上海凈信Tissuelyser多樣品組織研磨儀
研磨實例:
將酵母菌放置在2ml離心管內(nèi),放入1:1的小號玻璃珠,加入專用裂解液
放置在凈信研磨儀上,研磨數(shù)秒(顯微鏡下觀察如下圖所示:)
