MICROENCAPSULATION BASICS
Microencapsulation Basics: What You Need to Know
What is microencapsulation?
Microencapsulation is the process of surrounding tiny particles or droplets of active ingredients with a protective coating to form microcapsules. These capsules protect the ingredient, control its release, and improve performance in the final product.
Benefits include improved ingredient stability, protection from moisture, light, or oxygen, reduced volatility, controlled or triggered release, masking of unwanted taste or odor, and the ability to transform liquids into free-flowing powders for easier handling.
We work with a wide range of ingredients including fragrances, flavors, vitamins, nutraceuticals, functional actives, essential oils, and specialty chemicals.
Spray drying is a single technique that can be used for microencapsulation, but microencapsulation is a broader category of technologies — including matrix encapsulation, core-shell capsules, and other advanced release systems.
Industries served include fragrance, personal care, home care, textiles, food & beverage, nutraceuticals, pet care, and agriculture.
Technology & Technical Insights
Technical Insights: Microencapsulation Process & Performance
What types of microencapsulation technologies does Spray-Tek offer?
We offer multiple encapsulation methods, including spray drying, matrix encapsulation, and patented release systems such as Envicap™ and Trucap™. Each is selected based on your active ingredient, product format, and performance requirements.
Our technical team evaluates your ingredient’s properties, the desired release profile, environmental considerations, and end-use application to recommend the most effective solution.
Yes. We can design capsules that release upon contact, hydration, pH change, temperature shift, or over a sustained period — tailored to your product’s needs.
We work with a variety of materials including biodegradable and plant-based polymers, modified starches, proteins, and synthetic blends — always selected to align with performance goals and regulatory requirements.
Stability is achieved through careful selection of wall materials, optimized processing conditions, and rigorous testing to ensure capsules remain intact during storage and use.
Yes. Encapsulation protects sensitive actives from degradation, significantly extending shelf life in many applications.
Yes — we offer 100% biodegradable options like Envicap™, as well as other sustainable solutions designed to meet environmental and regulatory standards.
