Soya Peptone

Features

Our soya peptone can be divided into industrial and pharmaceutical grade. The main difference is that those products with higher specifications are different in the amount of total nitrogen and the solution clarity after varied production processes. The high-standard products are suitable for genetic engineering, and the other products are suitable for general usage in industrial fermentation.

Our raw materials (byproducts of soy beans) come solely from Northeast China and do not contain any GMO soybeans.

Application

Rich in carbohydrates and vitamins, soya peptone is suitable for the bacterial growth which has more stringent nutritional requirements and is widely used in antibiotics, vitamins, organic acids, enzymes and other fermentation industries.
