Precision, Purity, and Innovation at Umbria Olii International S.P.A.

At Umbria Olii International S.P.A., the refining of vegetable oils is not just an industrial process—it is a true expression of technical mastery and quality assurance. With decades of experience and a deep commitment to innovation, we have perfected two complementary refining methods: physical refining and chemical refining using our patented technology.

Each method serves a specific purpose, tailored to different types of crude oils and desired final characteristics, allowing us to offer a wide range of high-quality, sustainable products to the global market.

Physical Refining: Efficiency and Purity through Natural Processes

The physical refining process is widely recognized as a more natural and environmentally friendly method. It is especially suited for oils that are already relatively low in free fatty acids (FFA). The process includes three essential stages:

1. Degumming – Removal of phospholipids and mucilaginous substances.

2. Bleaching – Use of natural clays to remove pigments, trace metals, and oxidation products.

3. Deacidification and Deodorization – A vacuum steam distillation process that eliminates free fatty acids and volatile compounds, improving taste, odor, and shelf life.
   
   

At Umbria Olii International, our physical refining line operates with a daily production capacity of 180–200 metric tons. This process is highly energy-efficient and produces minimal effluents, making it a responsible choice for customers who value sustainability without compromising on quality.

Chemical Refining: Advanced Purification with Patented Technology

The chemical refining process, enhanced by our exclusive patented technology, is designed to treat oils with higher free fatty acid content or more complex impurities. This method is ideal for refining crude oils that cannot be processed using the physical method alone.

The main steps include:

1. Neutralization – Free fatty acids are removed using a controlled alkali treatment (usually sodium hydroxide), forming soapstock.

2. Washing and Drying – The oil is washed to remove residual soap and then dried.

3. Bleaching – Similar to the physical process, this step removes pigments and contaminants.

4. Deodorization – A high-vacuum steam process eliminates unwanted odors and flavors, ensuring a neutral and stable final product.

With a production capacity ranging from 100 to 200 metric tons per day, our chemical refining line guarantees maximum versatility and reliability. The proprietary innovations behind our patented process allow for superior yield, enhanced safety, and reduced environmental impact compared to conventional chemical refining systems.

Continuous Quality Monitoring and Environmental Responsibility

Both refining methods are conducted in fully automated, state-of-the-art facilities, operating 24 hours a day, 365 days a year. Our dedicated Quality Analysis Team carries out continuous checks in our in-house laboratory, ensuring that every step—from crude oil intake to final output—is meticulously controlled.

We are deeply committed to sustainable industrial practices, minimizing waste, optimizing energy consumption, and maintaining full compliance with international food safety and environmental regulations.
