The Soybean Protein Isolate Equipment produces soybean protein isolate, or SPI, a full price protein food additive. The raw material is low temperature desolventizing soybean meal, which keeps the protein in good condition for isolation. The production of soybean protein isolate makes use of the way the solubility of soybean protein changes markedly with the pH value: the protein is dissolved at one pH and precipitated at another, so the isolate can be separated from the other meal components cleanly.

Soybean protein isolate contains about twenty amino acids and includes the essential amino acids that the human body cannot make for itself. Its protein content is over 90 percent and it contains no cholesterol, which makes it one of the very few plant proteins that can be used to replace animal protein in a wide range of foods. The isolate is used as a functional and nutritional ingredient in processed meat, beverages, dairy alternatives and sports nutrition, where its high protein content and clean flavour are valued.

• pH separation: the solubility of soybean protein changes with pH so the isolate separates cleanly.
• Very high protein: the finished isolate contains more than 90 percent protein.
• Complete amino acids: about twenty amino acids, including the essential ones for human health.
• No cholesterol: a cholesterol free plant protein that can replace animal protein.
• Full price protein: a full price protein food additive for many food applications.
• Low temperature meal: uses low temperature desolventizing soybean meal to protect protein quality.

The soybean protein isolate equipment serves food ingredient plants that supply SPI to processed meat, beverage, dairy alternative and sports nutrition producers. Because SPI is cholesterol free, high in protein and complete in amino acids, it is widely used to raise protein content and improve texture in foods, and it is one of the leading plant proteins used to replace animal protein.

The line is shipped as process modules with the extraction, separation, washing and drying equipment protected and braced for sea transport. We provide the process design, P and I diagrams and a commissioning service, together with a twelve month warranty on the extraction vessels, separators and dryer.
