Presence in food

It is found in cocoa beans and chocolate.

Editorial summary

The public source identifies “Procyanidin B5” as chemical compound. This brief keeps that definition visible, then builds a research path around Procyanidin, chemical and compound.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 48-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Procyanidin, chemical and compound providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Procyanidin B5”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 31, 2025. The linked authority identifier is Q7247557. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
