Kapsyra™ Microencapsulation

Microencapsulation embeds or surrounds an active within a food-grade matrix or coating. The objective is protection and handling — not release modification.

The distinction that decides everything

Microencapsulation and modified release are different technologies with different evidence requirements, and conflating them is the single most common technical error in ingredient marketing. A matrix that protects an active from oxygen does not thereby delay its release. Describing it as “controlled release” asserts a functional property that has not been demonstrated and usually does not exist.

The entire NexaGens microencapsulated range is immediate / non-modified release. We state that on every product page and on the collection page, and we do not use the phrase “controlled release” anywhere except to explain why it is wrong.

What the matrix is asked to do

Function	Mechanism	Typical actives
Oxidation protection	Physical oxygen barrier, optionally with an antioxidant system in the matrix	Carotenoids, CoQ10, marine and algal oils
Light protection	Opaque or light-scattering matrix	Astaxanthin, lycopene, lutein
Moisture protection	Low-permeability matrix	Hygroscopic salts
Taste and odour masking	Barrier resistant in saliva, soluble in gastric fluid	Caffeine, iron salts
Oil-to-powder conversion	Emulsification followed by drying into a solid matrix	Fish oil, algal DHA, essential oils
Interaction protection	Physical separation of reactive species within a blend	Iron
Dispersibility	A carrier that wets and disperses more readily than the active	CoQ10, carotenoids

Quality control parameters

Parameter	Why it is specified
Active assay	Label claim and dose calculation
Surface active or surface oil	The most predictive parameter in the whole specification. Unprotected material on the particle surface oxidises first and dominates both sensory and early stability behaviour
Encapsulation efficiency	Proportion of active genuinely held within the matrix
Particle size distribution	Powder handling, blend uniformity, mouthfeel
Moisture and water activity	Water activity, not total water, drives degradation
Dispersibility	The functional outcome, measured rather than asserted
Peroxide, anisidine and TOTOX values	For oil powders, measured over time rather than at release only
Payload leakage	Whether the matrix holds under storage and compression

Current maturity

All twelve products are at Qualified status: manufactured, released against a confirmed specification and held in stock. Each production batch is supplied with a batch-specific Certificate of Analysis. Documentation available per ingredient includes the TDS, product specification, COA, SDS, allergen, GMO, irradiation and BSE-TSE statements, stability documentation, composition, storage and handling, and the microbiological specification. Where a product page states a functional benefit, we will provide the supporting data on request; where it has not been generated, the page says so.
