Research & Development Technical Services

Every product is unique and requires an assessment, having our team at the beginning of the process is critical. Whether it is product conception or product development, our team’s approach is meticulous and is handled on a case-by-case basis.

For new product concepts, we review processing of all materials, claim accuracy, and overall product assessment.

For products being considered for development, we provide specifications, descriptions, critical attributes, and controls to identify the unique requirement of the product.

Our technical services team collaborates with our research and development team along with our clients to compile all necessary documents required for the product. Certifications of Halal, organic, Non-GMO, allergen and other relevant documents are requested and reviewed to ensure all materials are appropriate for the product.
