Peony pollen products need to be shown to be free from genotoxic risk, and Aprofood's toxicology team provides the data to demonstrate it. Our genetic toxicity studies cover raw pollen, wall-broken pollen, extracts and finished products, and return reliable mutagenicity and clastogenicity results with a clear interpretation. Product developers can rely on these findings for new ingredient development, registration and market entry.
Genetic Toxicity
Genetic toxicity describes the capacity of a substance to damage genetic material, either through gene mutations (mutagenicity) or through structural or numerical chromosome damage (clastogenicity and aneugenicity). Because such damage can lead to serious long-term health effects, genetic toxicity testing is a core element in the safety evaluation of every food ingredient. A standard battery of in vitro and in vivo assays is applied, since no single test detects every type of damage. It covers gene mutation in bacteria, chromosome damage in mammalian cells and chromosome damage in living animals. Peony pollen has long been used as a food and traditional health material, yet wall-broken pollen, extracts and concentrated products differ in composition and contain higher levels of active compounds. Regulators therefore still ask for documented genotoxicity data on these products, because history of use alone cannot establish their safety, and a standardized battery is needed to rule out genotoxic risk for consumers.
Our Service
Aprofood's scientists bring extensive experience in toxicological safety evaluation to meet industry standards and regulatory requirements. Every study follows internationally recognized guidelines, including the OECD test guidelines and national food safety standards, and is tailored to the test material, its intended use and the target market. The following approaches are available for evaluating the genetic toxicity of peony pollen products.

Our Applications of Genetic Toxicity Testing
Genetic toxicity data play a role at several stages of peony pollen product development and market entry. Aprofood designs each study to match the purpose behind it, as shown in the applications below.
| Application |
Description |
| Pollen Genotoxicity Evaluation |
Raw and wall-broken pollen can be assessed for potential genotoxic effects, helping confirm the safety profile of pollen materials with a history of food use. |
| Extract Assessment |
Extracts and concentrated pollen ingredients may require separate evaluation when processing alters their composition or changes the levels of active compounds. |
| Novel Food Registration |
Genotoxicity data can form part of a novel food safety dossier, alongside acute, teratogenicity, and 90-day subchronic studies planned for the target market. |
| Finished Product Verification |
Marketed forms such as tablets, capsules, powders, and beverages can be tested using sample preparation procedures suited to each assay system. |
| Formulation Screening |
Different batches, processing methods, or formulations can be compared for genotoxic potential to support selection of the most suitable option before further development. |
Our Workflow of Genetic Toxicity Testing
01
Study Design
We review the test material, intended use, target market, and study objectives, then develop a study protocol and quotation for confirmation. The protocol specifies dose levels, animal numbers, study duration, and applicable guidelines.
02
Sample Preparation
The test material is characterized and prepared into a suitable dosing formulation. Homogeneity and stability are assessed to ensure consistent and representative dosing throughout the study.
03
Animal Acclimation
Healthy animals are acclimated under controlled laboratory conditions before dosing. Temperature, humidity, lighting, diet, housing, and general health are monitored throughout the acclimation period.
04
Dosing & Observation
Animals receive the test material by oral gavage at the specified dose levels and are monitored throughout the study period. Clinical signs, behavior, food intake, body weight, and other relevant observations are recorded at scheduled intervals.
05
Necropsy & Data Analysis
Gross necropsy is performed at study completion, with histopathological evaluation conducted when required. Study data are analyzed to identify treatment-related findings and assess overall toxicity.
06
Final Reporting
A comprehensive report summarizes study procedures, observations, toxicity findings, and conclusions. Raw data and recommendations for further safety or toxicological studies are provided where applicable.

Frequently Asked Questions (FAQs)
Q1: Can you work with the specific form of my peony pollen product?
A1: Yes, raw pollen, wall-broken pollen, extracts, powders, tablets and capsules are all accepted for testing. Each material is dissolved or suspended in a vehicle chosen for its solubility and physical properties. If your product has an unusual form, send us the details and we will advise on the preparation the assays require.
Q2: Do I need the full battery or only some of the assays?
A2: Most food ingredient dossiers start with a bacterial reverse mutation test and a mammalian cell test for chromosome damage, and add an in vivo micronucleus test when regulators ask for it. The right selection depends on your product and the market you are targeting. Our team can recommend a battery that fits your regulatory pathway.
Q3: How much material should I prepare before sending samples?
A3: The quantity is driven by the number of assays, the dose levels, dose range finding and retained samples. In vivo tests generally consume more material than in vitro tests. The exact amount is fixed in the study protocol before work begins, so you have time to prepare enough.
Q4: When can I expect the final report?
A4: Each in vitro assay usually takes a few weeks, while an in vivo micronucleus test needs longer for animal acclimation, dosing and sample analysis. Report preparation then adds further time. A full schedule is confirmed together with the quotation.
Q5: Does one positive result mean my product is genotoxic?
A5: Not necessarily, because in vitro tests can give findings that are not relevant in vivo. The report explains how to interpret each result, and follow-up tests can be designed to clarify any positive outcome. Our team is available to discuss the findings and next steps with you in detail.
Q6: Can the genetic toxicity battery be combined with other safety studies?
A6: Yes, acute oral toxicity, teratogenicity and reproductive toxicity, and 90-day subchronic oral toxicity studies can all be planned alongside it. A shared test material and consistent documentation save time and keep the data comparable. The full safety evaluation can be designed around your regulatory pathway.
