Texturized vegetable Protein (TVP)


IDAH has developed numerous ready-to-sell textured vegetable protein (TVP), or specifically textured soy protein from soy isolate powder. We have complete know-how from formulation and processing equipment.

Item Texturized Vegetable Protein (TVP)
Characteristic Low moisture extrusion
Moisture in extruder outlet (%wb) 17-23
Moisture in dryer outlet (%wb) 7-9
Texture The expanded, fibrous, spongy texture

Co-rotating extruder for TVP

Raw material

The raw material consists of high protein powdery material

Dry mixing

In this step, trace ingredients such as vitamins and minerals will be added and mixed


During extrusion, the material will undergo high pressure, high temperature, and shearing in the barrel.
This treatment will induce the formation of protein fiber.


Drying in TVP is an optional process, some TVP will be frozen and distributed in wet form.
When dried, wet TVP will enter the dryer and come out as dried TVP with long shelf life.


Cooling utilizes ambient air to cool down the hot product coming out from the dryer.
Thorough cooling is needed to prevent condensation inside the packaging.


Packing gives protection to the products also gives easiness to handle and transport to customer's hand.

Manufacturing Process of TVP

Twin shaft mixer Food safety is the key feature for the IDAH twin shaft mixer. IDAH mixers ensure high accuracy of mixing and hygienic features such as minimized residue and bacteria growth. IDAH mixers used for food applications have been delivered to many countries including Japan, Korea, China, and Taiwan.
Twin-screw extruder IDAH co-rotating twin-screw extruder offers excellent solutions based on years of commercial operations and research works. Innovative human-machine-interface or HMI designs help customers to record all parameters including temperatures on the barrels, speed of shaft rotation, metering of water or other liquid addition, and automatic start-up and turn-down. Control systems make IDAH twin-screw extruder highly flexible in making an unlimited variety of products.
Drying system IDAH carousel dryer has an especially small footprint and height compared to typical vertical counterflow dryers and also uses a lot less electrical power than most other designs, cutting down on capital costs, energy costs, maintenance costs, and noise. A round-shaped carousel dryer generates a very homogeneous air flow stream inside the dryer which allows an extremely uniform treatment of the product. This process of airflow leads simply to the fact that over-drying of the product is not given. Constant tumbling (up to seven times) of the product to be dried leads to best results in uniform water evaporation.

Features and Benefits of IDAH Process Design and Equipment

Since the 1980s’, Taiwan has used soybean and wheat as two base materials to develop textured vegetable protein (TVP) technology. The textured vegetable protein has a meat-like texture and can be made into various healthy vegetarian food products. Based on decades of experience in operating a vegetarian food company, IDAH has complete know-how in converting textured vegetable protein (TVP) into different plant-based meat (vegetarian meat).

The 1990s

IDAH has established a food laboratory since the 1990s, specializing in TSP (Soy Extruded Protein) and IWP (Soy Protein Isolate), and successfully developed plant-based meat (vegetarian meat).

The year 1997

The laboratory was upgraded to a food research factory and began to produce various vegetarian products.

The 2000s

Technical cooperation with the Food Industry Research Development Institute of Taiwan, and the Food Research Institute of Taiwan Ocean University, successfully exported vegetarian meat to the United States.


The food plant of vegetarian meat products was sold to Taiwan Top 5 food company in Taiwan.


IDAH Innovation Center was established to continue to research and develop plant-based meat, becoming the first and only base in Taiwan to provide vegetarian meat equipment, proofing and testing, education and training, and food research and development.
