以色列采购需求：透明质酸钠、透明质酸、玻尿酸、化妆品级透明质酸钠、化妆品级玻尿酸、食品级玻尿酸

I'm currently sourcing high-quality soy protein for the range of protein products I manufacture in Israel. Specifically, I'm interested in a product with a soy protein concentration of around 90%. Before proceeding, I'd like to confirm whether your products come with a kosher certification, as this is essential for my business operations. If your soy protein meets this requirement, I'd be happy to share detailed product specifications via email so we can discuss potential ordering and partnership opportunities. Looking forward to your prompt response!
