CIP Validation Test / Riboflavin Test

Independent Integrity Inspection Limited CIP Validation inspection / Riboflavin test is a test to validate the hygienic design and actual hygienic condition of your equipment.

Within the food, brewing, drink and pharmaceutical industries there is an ever-present risk of product contamination that, if undetected, could result in product recalls, damage to brand names and, in the worst case, serious illness or death to a consumer.

Tests for an examination of cleanability play a major role in sterile process technology.  Riboflavin testing provides a solution to validate the effectiveness of the CIP (Cleaning In Place) procedure.

Advantages include:

Validation of CIP installations in new equipment.

Validating the CIP installation as part of FAT ( Factory Acceptance Test ) or upon final installation allow you to avoid design-related hygienic problems and take corrective actions before the start of production. Saving costs and production downtime.

Validation of modifications.

In case of modifications to your equipment, the CIP validation provides certainty that your equipment is cleanable.

Riboflavin testing also provides solutions of what may be causing contamination as testing is the only proven way to efficiently monitor spray coverage, which is needed for a sanitary clean.

Common Issues affecting CIP cleaning.

The most common issues connected with CIP cleaning:
CIP test / Riboflavin testing, biofilm formation adhesion, FAT testing
