Soy Protein Isolate (SPI) is a highly refined form of protein derived from defatted soybean meal. Through a process involving alkaline extraction and acid precipitation, it achieves a protein content typically exceeding 90% on a dry weight basis, making it one of the purest plant-based protein sources commercially available.
SPI possesses a neutral flavor, excellent nutritional value (containing all essential amino acids), and a range of functional properties including water/oil binding, emulsification, gelation, and foaming. These characteristics make it an indispensable and versatile ingredient in the food, nutrition, and industrial sectors.

This is the primary application area. SPI is extensively used in processed meat products (e.g., sausages, burgers, deli meats) to improve texture, juiciness, bind water and fat, and enhance nutritional profile. It is the key structural ingredient in plant-based meat alternatives (veggie burgers, nuggets), providing the fibrous, meat-like texture and protein content. It also serves as an emulsifier and stabilizer in soups, sauces, dairy alternatives (like soy milk and yogurt), and baked goods.
Due to its high protein quality and digestibility, SPI is a fundamental component in sports nutrition products (protein powders, bars, and shakes), meal replacement supplements, clinical nutrition formulas, and geriatric nutritional products. It helps in muscle synthesis, satiety, and meeting protein requirements.
Standard packing includes 25 kgs bags or jumbo (ton) bags. Custom packing is also available if you have a legally registered patent for specific packaging or special needs (subject to relevant document confirmation, if applicable).
Accepted payment methods include T/T, Western Union, Bitcoin, and Tether (USDT). Please confirm your preferred method with the sales team before placing your order.
For small packages (such as samples or small-quantity orders), we ship via international couriers (DHL, UPS, FedEx, EMS). For bulk shipments, we arrange sea or air freight based on your order volume and delivery timeline.
In-stock products are shipped within 1~2 business days after receiving your advance payment. For custom or non-stock products, the timeline varies by product type and order quantity, which will be clearly detailed in your quotation.
We maintain a low MOQ for small-batch purchases (specific details are provided in your quotation). Additionally, we can provide not less than 1 kg of free samples for quality testing, though customers are expected to cover the shipping costs.
We perform a 100% quality inspection for all products before delivery. If any quality issues arise due to our production or inspection process, we offer free replacements or refunds (subject to issue confirmation via photos or videos).
