Plant Protein丨How to extract high-quality protein from oil crops such as soybeans?
Gently utilize soybeans, rapeseeds, and lupins
Soybean protein and lupin protein have truly become substitutes for animal protein in the food industry. They are used as raw materials for plant-based foods to replace meat and dairy products, and the increasingly popular isolated proteins are usually by-products of extracting oil from oil crops.
Powerful functionality
The protein extraction process requires the use of a horizontal decanter centrifuge, such as for the extraction of lupin protein and soybean protein, Flottweg can ensure the high purity and high functionality of its products. Our customers can extract all available materials from raw materials to improve economic and ecological sustainability.
Fully automated production line
SENZ solutions provide wet separation, which is the core method for extracting protein from oil crops. Our range of production solutions for extracting soy protein, rapeseed protein, or lupin protein is extensive, from manually controlled single devices to fully automated production lines.
High-quality protein as a by-product
Soybeans, rapeseeds, sweet lupine seeds, sunflower seeds, or flaxseeds are commonly used raw materials for producing high-quality oils. The residual filter cakes still contain high-quality proteins, such as soybean protein or lupine protein. More and more oil mills are starting to process these filter cakes. In addition to plant proteins, the remaining fibers, namely soybean dregs, can also be dried and processed..
Our decanter centrifuge is used to extract protein from oil crops with a production capacity of 200 kilograms (441 pounds) per hour.
Principles Of Extracting Plant Protein From Soybeans, Rapeseeds, Or Lupins
Before extracting protein, the fat or oil contained in oil plants has been separated. The first step is extraction, which is a multi-stage process to extract oilseed plant protein from filter cakes or rapeseed, lupin, or soybean powders. The next step is coagulation, where the protein settles and separates in the solution. Depending on different requirements, additional washing steps can increase the precipitated protein content, allowing for the production of concentrated protein, or even high-purity isolated proteins, such as pea isolated protein.
The produced protein has the highest purity and excellent functionality, and can be directly sent to the spray drying process. To achieve the best protein yield, additional non-functional proteins can be recovered through heat precipitation methods. When necessary, residual fibers are washed, then mechanically dehydrated using SENZ belt press, and finally dried.

Prolupin GmbH uses SENZ centrifuges to extract lupin protein
Lupin processing places high demands on both people and machines. After cooperating with SENZ, Prolupin GmbH is able to use lupin protein as a food ingredient. First, ground and deoiled lupin flakes are mixed, then the fiber and protein are separated using the SENZ horizontal decanter centrifuge. Another horizontal decanter centrifuge separates the coagulated lupin protein from the insoluble fiber. The remaining plant-based lupin protein undergoes cleaning and processing in a SENZ horizontal decanter centrifuge.
