潜水简介:
- Upside Foods has developed ananimal-component-free cell growth feed，它用来帮助其细胞生长成肉。多年来，该公司一直在朝着这一目标努力。
- Upside Foods产品和调节高级副总裁Eric Schulze表示，细胞生长培养基与传统的动物生长饲料基本相同的成分 - 氨基酸，脂质，糖，维生素，矿物质，水和其他营养素，以帮助细胞蓬勃发展。他说，无动物的生长培养基与使用从动物中获取的蛋白质的前身一样有效地工作，并没有导致生长过程或时间变化很大。
- 生长培养基是栽培肉的价格较高的成分之一。Schulze不会对无动物生长媒介的成本发表评论，但表示，Upside的耕种鸡肉目前的成本与优质动物衍生的鸡肉相当，并且比某些常规的家禽削减的市场价格便宜。
潜水见解：
为了成为肉类市场的真正参与者，基于细胞的空间需要完成一些事情。最重要的之一是，其价格与动物衍生的肉类相似，甚至比动物衍生的肉类相似甚至少。增长媒介的成本大大增加了这个价格。第一个基于细胞的汉堡包是由在昂贵的动物衍生胎牛血清中生长的牛肉细胞制成的 -cost roughly $325,000.
Schulze said Upside Foods has been working on the animal-component-free serum for years with a team of in-house experts. According to a release from Upside Foods, some of these team members are former leaders from leading biotech and pharmaceutical companies. They started the process by removing fetal bovine serum from the growth medium and then replacing some of it with animal-derived proteins and other components, Schulze said. Those components have been replaced in the current iteration.
所有使用技术根据药品到医疗设备再到食品的细胞生产产品的公司都在努力从其生长媒体中删除动物组件。舒尔兹说，开发合适的产品可能需要数十年的时间，他为2015年以孟菲斯肉类成立的上升食品而感到自豪，能够在很短的时间内做到这一点。
Schulze said he thinks this development will be "encouraging our industry and other industries to, again, move and question and refine their medium as well, to produce animal-component-free media."
Other companies working on cultivated meat have developed less costly, plant-based growth media options. Mosa Meat, the Dutch company that arose out of the 2013 cell-based hamburger,removed all fetal bovine serumfrom its growth medium in 2020, which led to an 88-time reduction of its cost. Mosa Meat announced in May it alsoremoved all animal components从培养基中，它用于种植基于细胞的脂肪，使3月的血清成本仅为其2019年9月价格的1.52％。
以色列的未来肉类技术也有无动物的生长培养基that was developed in partnership with Archer Daniels Midland. Future Meat's robotic analytical system scanned through different plant proteins, finding ones that could provide vital nutrients to growing cells. The company's bioreactors also have a cleaning mechanism, meaning that growth medium can be reused. In February, Future Meat said this had lowered the price to make a cell-cultured chicken breast to $7.50.
其他公司正在努力实现这一目标。2020年1月，动物营养公司Nutreco与Mosa Meat和BlueNalu帮助开发无动物的生长培养基。就在本周，Aleph Farms宣布与德国化学制造商Wacker的合作伙伴关系to produce proteins needed to make animal-free growth media. The proteins Wacker develops will also be available on the open market to other companies in the space.
舒尔兹说，上升食品的无动物生长媒介将受到美国农业部和FDA的联邦法规，这是该部门对公司最终产品的全面关注的一部分。首先，据新闻稿称，上升食品利用这种生长媒介来制作鸡肉热狗和掘金，但舒尔茨表示，该公司最终将在整个产品组合中使用它。
