What was done
This narrative review synthesized literature on microencapsulation strategies for sulforaphane and related isothiocyanates, evaluating encapsulation efficiency, degradation rates across different delivery systems, and the impact of post-encapsulation drying conditions for food matrix integration.
What was found
The abstract reports no numerical data. Qualitatively, ionic gelation and complex coacervation appeared most suitable for stabilizing sulforaphane, though both remain underexplored. Drying conditions were identified as a critical determinant of stability due to thermal degradation, and existing literature was determined to be insufficient to define optimal processing conditions.
Why it matters
Sulforaphane is highly unstable in ambient conditions, posing a major barrier to its use in functional foods. Understanding formulation methods is a necessary technical step toward developing stable oral or food-based delivery systems.
Limits
No quantitative findings or sample sizes (number of papers included) are reported in the abstract. The paper is a non-systematic review of food chemistry and processing techniques with no in vivo, pharmacokinetic, or human clinical outcome data.
