From curing to smoking, we’ll cover it all. So, let’s dive in!

What Is Fish Preservation?

Di zaman sekarang, fish preservation refers to the process of extending the shelf life of fish by applying a range of techniques. These methods are designed to prevent the growth of bacteria that can lead to spoilage, discoloration, and foul odors. Fish preservation techniques can be applied to fresh fish, as well as to fish that have been processed in some way, such as by filleting or canning.

The Importance of Fish Preservation

Maintaining the quality and safety of fish is crucial for health and economic reasons. Spoiled fish can cause a range of illnesses, from mild stomach upsets to serious infections. Additionally, fish is a valuable commodity, both for personal consumption and for trade. By preserving fish properly, we can ensure that it remains safe to eat and can be enjoyed for longer periods of time.

The Basics of Fish Preservation

Before we dive into the various preservation methods, let’s take a quick look at the basics. There are a few key factors to consider when preserving fish:
