Services

We follow a clearly structured process that begins with a detailed briefing, continues through creation and prototyping in the lab, includes application testing, and concludes with final approval and handover to production. Our focus is on efficient, transparent, and reproducible steps, and we consider the involvement of our customers in the development process a key success factor.

Our laboratory in Hamburg is the central hub for quality and safety. Every step, from raw material testing to batch release, is subject to rigorous controls. Our processes are certified according to international standards (e.g., FSSC 22000) to ensure maximum product safety and compliance for global markets.

Yes. We specialize in the precise modification of existing formulations. This is often necessary for entering new markets with specific legal requirements regarding composition, or for optimizing release kinetics and shelf life. In doing so, we ensure, as far as possible, that the characteristic flavor is fully preserved.

Our specialists test the flavors directly in their respective end applications. This includes evaluating the sensory effects in the final product, as well as conducting tests on heat stability (e.g., shisha), solubility, dosage, and material stability (e.g., nicotine pouches) to guarantee consistent flavor release and a technically flawless end product.

A specialized team focuses on the international and local regulatory frameworks. In collaboration with our clients, we ensure that all developed solutions fully comply with the legal requirements of the respective target markets, guaranteeing global marketability and compliance of the final products.

We develop tailor-made flavor concepts that are precisely adapted, both sensorially and technologically, to the customer's specific application, product, and production processes. Instead of relying on standard profiles, we offer customized solutions that guarantee the highest possible market maturity and differentiation.

Through the close integration of design, laboratory, and application technology. We rely on targeted prototyping and technical fine-tuning in our application laboratory to address and resolve challenges such as color stability, storage under different climatic conditions, or specific filling processes at an early stage.

At Hertz & Selck, we prioritize certified safety and top-notch quality. Our processes are certified according to international standards. Every batch undergoes rigorous testing in our in-house Hamburg laboratory to ensure maximum product safety and compliance for global markets.
Our company is certified according to ISO 9001 for excellent quality management and according to FSSC 22000 for a comprehensive food safety management system. Furthermore, by complying with the EU Organic Regulation (DE-ÖKO-072), we guarantee the highest standards in the development and production of our organic flavorings.

Through documented, standardized production processes and the use of modern analytical technology, we work with the best conditions for consistently high quality and reproducibility of our products – this is the technical basis for scalable flavors with reliable functionality throughout the entire life cycle of the customer's product.
