lautnusantara.comOctopus is a highly nutritious seafood product, particularly known as a source of high-quality animal protein. In frozen form, octopus is widely traded both domestically and internationally. This article discusses the protein content in frozen octopus, its health benefits, and the effects of freezing on its nutritional quality.

Introduction

Octopus (order Octopoda) is a soft-bodied marine animal consumed in many countries for its unique flavor and rich nutritional value. In Indonesia, octopus is increasingly utilized not only in its fresh form but also as a frozen product for export or longer shelf life. Protein content is one of the key indicators of the nutritional quality of frozen octopus.

Protein Content in Frozen Octopus

Octopus contains approximately 15–20 grams of protein per 100 grams of flesh, depending on the species, size, and habitat. Octopus protein is considered complete, as it contains all essential amino acids, such as lysine, leucine, valine, and methionine. In its frozen form, the protein content of octopus generally remains stable when freezing is done properly (quick freezing at −18°C or lower).

Studies show that although freezing can cause some structural changes in proteins (denaturation), the nutritional value of protein in frozen octopus remains largely unaffected. In fact, freezing helps prevent enzymatic and microbial degradation that could otherwise damage protein quality.

Health Benefits of Octopus Protein

1. Supports Growth and Cell Repair
   Essential amino acids in octopus protein are crucial for tissue regeneration and overall growth.

2. Improves Muscle Health
   The high protein content is especially beneficial for individuals with increased protein needs, such as athletes and the elderly.

3. Boosts the Immune System
   Octopus protein contributes to the formation of antibodies and essential enzymes that strengthen immune defenses.

4. Low in Fat and Rich in Nutrients
   In addition to being protein-rich, octopus is low in fat and contains micronutrients such as iron, zinc, and vitamin B12.

Effects of Freezing on Nutritional Quality

If not done properly, freezing can cause moisture loss and a tougher texture upon thawing. However, with rapid freezing techniques such as IQF (Individually Quick Frozen), protein degradation can be minimized. Therefore, maintaining proper temperature and duration during storage is crucial to preserving the nutritional quality of frozen octopus.
