Chitinase-based Food Preservation Solution

Chitinase-based Food Preservation Solution

Chitinase is a promising candidate enzyme, especially when it comes to preventing fungal contamination in food. These enzymes act on chitin, the basic component of fungal cell wall, and do not cause any damage to food. Aprofood deeply explores the field of enzyme engineering and is committed to providing comprehensive chitinase-based food preservation solutions to customers around the world.

Overview of Chitinase

Overview of Chitinase

Chitinases (EC are glycoside hydrolases that act by stimulating thesplit of the β-1,4 glysosidic bonds between the N-acetyl-d-glucosamine (GlcNAc) chains that make the chitin polymer. Chitin widely exists in the environment and is the main component of insect exoskeleton, fungal cell wall and arthropod shell. Chitinase catalyzes the hydrolysis of glycosidic bonds in chitin, leading to its degradation into low molecular weight products, such as chitosan oligosaccharide (COS) and GlcNAc. The physicochemical properties and sources of chitinase are the main basis for determining its functional properties and hydrolysates. Several chitinases have been studied and characterized, and they are widely used in agriculture, food, environment, medicine and pharmaceutical companies.

Application of Chitinase in Food Preservation

Food can be preserved by several methods, whether chemical or microbial. However, the use of microorganisms and their products has some advantages, such as feasibility, time saving and cost saving. Chitinase producing microorganisms showed good antifungal effects on most post-harvest fungal pathogens for example, chitinase (ChiC) produced by Salinivibrio sp. can be used for food preservation because it shows antifungal activity against fungal pathogens (Rhizoctonia solani and Fusarium oxysporum). Chitinases can be used for food preservation because they destroy fungal cell walls, inhibit spore germination, and thus reduce food spoilage. Therefore, it can be concluded that chitinase can be used as an effective and promising food preservation strategy.

Our Solutions

Combining enzyme engineering technology and expertise in the food industry, Aprofood is committed to providing global customers with comprehensive solutions for food preservation based on chitinase.

  • Formulation Customization of Chitinase
    Based on the antifungal activity of chitinase, we provide customized food preservation formula based on chitinase (which can be compounded with a variety of food preservation ingredients). The application forms that can be developed include: preparation, coating, film, etc.
