What was done
This narrative review summarizes biochemical mechanisms and food processing strategies affecting the stability and formation of sulforaphane from glucoraphanin in brassica vegetables. It evaluates factors including plant myrosinase preservation, epithiospecifier protein activity, thermal and non-thermal processing methods, and gut microbial hydrolysis.
What was found
The abstract reports no numerical or quantitative findings. Qualitatively, it highlights that sulforaphane and plant myrosinase are thermal-labile, epithiospecifier protein directs glucoraphanin hydrolysis toward sulforaphane nitrile instead of sulforaphane, and bacterial myrosinase has low hydrolytic efficiency. It identifies the need for novel cooking/blanching methods, thermostable enzymes, and high-producing microbial approaches.
Why it matters
Identifying the factors that limit glucoraphanin-to-sulforaphane conversion is critical for designing food processing and preparation strategies that maximize dietary intake of bioactive sulforaphane.
Limits
This is a narrative review with no systematic search protocol, quality appraisal, or primary human trial data reported in the abstract. No quantitative effect sizes or specific intervention outcomes are provided.
