MeaTech以色列食品技术公司（Israeli Food Technology）宣布了最新的里程碑，以寻求使用3D生物打印技术开发可持续的培养肉类产品。
Using its own in-house process, the company has successfully 3D bioprinted a 3.67 oz (104 gram) cultivated steak at its lab in Ness Ziona, Israel. The steak is composed entirely of real fat and muscle cells, meaning it doesn’t rely on any meat-free alternatives like soy or pea protein. According to MeaTech, the project was the result of over a year of R&D for the company’s cellular biology, high-throughput tissue engineering, and precision bioprinting processes.
该公司认为，其最近的工作是有史以来最大的培养牛排，这是朝着该公司3D生物打印耕种肉类产品的主要飞跃。
Meatech的首席执行官兼首席技术官Sharon Fima说：“通过生物打印3.67盎司的牛排，由活组织组成，我们相信我们既验证了我们的核心技术，又将自己置于种族的最前沿，以发展高端，真实的细胞 -基于耕种的优质肉类产品。”
MeaTech: disrupting mother nature
Meatech的使命是基于3D Bioprint Lab的培养肉，它是传统牛排的“真正替代品”，以各种方式模仿真实的东西。该公司开发了一个3D生物生产商，该生物生产商可与真实的，活的肌肉和脂肪细胞一起使用，而不是基于植物的替代品。生物生产商的技术最初在2020年11月成功测试，当时该公司首次制造了可食用的培养牛肉脂肪结构。
除了消除动物的屠杀外，该方法还有望为生产者，减少温室气体和潜在的健康优势提供大量供应链利益。
February 2021 saw肉技术获得肉的安宁, a Belgian developer of cultured fat products, for a total of $17.7 million split between cash and equity. The company has since利用肉类以禽为中心的技术的平静to expand its current capabilities, which were previously predominantly bovine meat-oriented.
在肉类交易的平静之后，据报道，肉科的最新里程碑之一是在9月份进行的，当时它设法耕种了700克纯鸡肉脂肪据信是同类的第一个生物量3D打印演示。在批准之前，Meatech打算在明年的一家试点工厂生产脂肪，在该工厂将作为增强味道成分销售。
The company has also recently begun research into the best way of缩放猪肉细胞的3D生物打印, and if this can be achieved successfully, it believes this could significantly expand its addressable markets.
“We intend to continue leveraging our 3D bioprinting technologies, which we believe to be the optimal technology to create structured meat tissues, such as steaks, under lab conditions,” adds Fima. “We believe that developing additional cultured meat product lines has the potential to generate additional revenue potential.”
The 3.67 oz cultivated steak
为了创建牛排，Meatech采用了其专有组织工程工艺的使用。
该技术是通过首先将牛干细胞从组织样品中分离出来的，并将其繁殖直至达到足够的细胞质量。一旦进入这个质量，该公司就将干细胞制定成生物墨水，以与Meatech自己的内部挤出基于基于的3D生物生物生物机一起使用。使用牛排结构的数字模型，该公司可以制造牛排并将其放入孵化器中以成熟 - 这是干细胞分化为最终脂肪和肌肉细胞的地方。
Meatech表示，计划继续开发其种植和生物打印技术，直到能够生产与农场饲养的牛排几乎没有区别的肉。
