Understanding Two Types of Preservatives: The "Freshness Game" and Synergy Between Chemical and Biological Preservatives

Among preservatives, chemical preservatives and biological preservatives represent the two main categories: the former dominates the market with its high efficiency and convenience, while the latter has emerged as a new consumption trend thanks to its natural and safe properties. Today, let’s break down the advantages and disadvantages of common preservatives, and see how these two types of "guardians" perform their respective duties, complement each other, and coexist harmoniously.

Two Natural Food Preservatives: Nisin vs. Lysozyme and Their Synergy

In the field of food preservation and biological freshness maintenance, nisin and lysozyme are two widely used natural biological preservatives. Though both act as safe and highly effective "green guardians", they differ significantly in origin, mechanism of action, and application scenarios. At the same time, they form a clever synergy that builds a double line of defense for food safety.

Preservative Partners in Food: The Ins and Outs of Nisin Blending

There are many types of preservatives and fresh-keeping agents in food, but each has its own "area of expertise". For example, some only work on specific bacteria. That’s why food manufacturers often "team up" two or more preservatives to achieve better anti-corrosion effects.

Lysozyme: Nature's "Antibacterial Guard"

Lysozyme is an alkaline protease widely found in nature, with an excellent ability to destroy bacterial cell walls. This seemingly tiny substance is actually an important member of the biological defense system, and it can be found in many substances from egg white to human saliva.

Unveiling the Secrets of Nisin: The Superhero of Food Preservation

Have you ever wondered how your favorite packaged snacks stay fresh for so long? Enter Nisin, a natural preservative that’s like a tiny superhero protecting our food from spoilage. But even superheroes have their weaknesses, and using Nisin the wrong way can turn it from a protector into a “pretender.” Let’s dive into the common mistakes and smart fixes when using this fascinating ingredient.

Locking freshness by coating

Food preservation technology has been constantly developing over the years. Among the new technology, edible coatings have attracted much attention due to their environmental friendliness and effectiveness. Recently, a study by Chinese scholars has verified the great potential of new edible coatings in the preservation of blueberries. This study has not only brought new ideas to the food industry but also provided inspiration for the preservation of a wider range of fruits and vegetables.

A Highly Effective Natural Food Preservative Derived from Plants Discovered

The scientists of Nanyang Technological University, Singapore (NTU Singapore) have discovered a plant-based food preservative which is more effective than artificial preservatives.
