这家公司名为Prime Roots，现在在网上推出了第一款限量产品，是由真菌加工成的培根。Prime Roots公司联合创始人 Le说培根是“供不应求的肉类替代品，市场上有很多牛肉粒，但像培根或鸡胸肉这样带纹理的肉或者更成形的肉类货量不足，而这些正是日本酒曲能够复制的肉类。”

该公司在位于伯克利市的总部用发酵桶培养真菌，和酿造啤酒或日本清酒的过程相同。给酒曲的“种子”加营养素，几天就能长成长长的纤维。Le说：“这些纤维的纹理和外观与鸡胸肉的纤维类似。”他们从培养液中过滤出纤维，然后加入植物脂肪和香料，就做出了成品。

她说：“我们基本上就做出了五花肉，有天然的脂肪和味道。我们其实是把肉放在烟箱里熏，就跟你做培根时熏五花肉一样。熏好以后就入味了，然后用切片机切成片，和培根的做法一样。”
