I'm currently sourcing kosher powdered beef gelatin for a potential product line we're developing for Whole Foods Market. It's essential that the gelatin meets high standards for quality and complies with kosher certification. We're particularly interested in any information regarding the sourcing of your beef, processing methods, and any certifications that assure the product's kosher status. Additionally, could you provide details on the available packaging options, minimum order quantities, and lead times for delivery? Understanding your pricing structure and any flexibility for larger orders would also be beneficial. Looking forward to your prompt response as we aim to finalize our suppliers soon.
