Is It Possible To Use Plastic Containers for Fermentation?

The organisms responsible for the process of fermentation can live in a plastic container like any other material. For several reasons, plastic is not preferred for fermentation.

Difficulty of Cleaning

Generally speaking, it is easier to clean and sterilize smooth, nonporous materials like glass.

Prone to Staining

Plastic may retain odors after it has been fermented.

Unwanted Bacteria

It is important to cultivate the bacteria you want and to prevent the bacteria you don’t want.

The quality of your ferments may be affected by the small scratches and scuffs on the plastic that can trap and hold unwanted bacteria.

Unwanted Chemicals

Depending on the type of plastic it is, it may contain chemicals that aren’t good for you.

When liquids are very acidic, warm, or stored for a long period, these chemicals may degrade and enter your ferments.

If You Must Use Plastic

If you want to ferment in a plastic container, here are some important things to consider.

Choose Food-Grade Plastic

Avoid plastic mixed with BPA or BHA. You need to choose HDPE, LDPE, polypropylene, or polycarbonate.

Clean Gently

If you want to avoid scratching the surface of the plastic containers, you should clean them with gentle, nonabrasive cleaners.

There are small dents and scratches on the surface of plastic containers that can facilitate the colonization of bacteria.

Sterilize Between Uses

It is important to remember that cleaning and sterilizing are not the same thing. It’s a good idea to avoid soaking plastic containers in a solution that degrades the plastic.

If you want to spray plastic containers with a 70% isopropyl alcohol solution, soak them in a 3% hydrogen peroxide solution for 15 minutes.

You can ferment foods in high-quality plastic if you clean and sterilize them correctly.
