About winterization
Base product processing
During production of our high DHA algal oil from biomass of the Schizochytrium algae strain, mechanically extracted biomass is dewaxed, degummed and winterized. This results in a crude algal oil, which is later refined into the final product.

Winterization
All standard oils from Progress Biotech are winterized, referred to as type-S. The winterization process removes a part of the saturated fatty acids from the oil. When producing special winterized oil, an extra winterization step is introduced, referred to as type-W. This step is also known as known as second or double winterization. The objective of this extra winterization is to remove components that crystallize at lower temperatures. Although this process is reversible, precipitations are not desired in high end applications. The second winterization results in a completely clear oil with a very low crystallization point. Progress Biotech designates this type of product as winterized oil (type-W). 

When to use type-S or type-W oil
It is advised to test oils for the specific application and determine the suitability of both types for the intended application. The winterization process brings extra costs to the process and results in a more exclusive ultra-pure oil. The standard oils (type-S) are perfect for incorporation in powders and food applications, as well in softgels and capsules that are not transparent. The double winterized oils (type-W) are the premium product designed for clear capsules that will remain transparent even when stored in the refrigerator (4ºC).

What’s the difference between Natural TG, TG, EE, and rTG?
​Natural Triglycerides (TG)
For Progress Biotech, Natural TG means a chemically unchanged form of TG. This is the natural form of DHA in algae as found in nature, with no compromises made on quality or purity. All 40% and 50% oils by Progress Biotech are natural TG. 

What are triglycerides (TG)?
Triglycerides are composed of 3 fatty acids bound to a glycerol backbone molecule. TG is the most common form of fatty acid found in nature. 

​Ethyl esters (EE)
​To increase the content of DHA, it is possible to concentrate the oil. This is done via ethylation and trans-esterification. During ethylation, the glycerol backbone of the TG is removed, resulting in free fatty acid forms of DHA. Then, during the trans-esterification, the free fatty acid forms of DHA are esterified with ethanol to form ethyl esters, resulting in an increased DHA content.

​Re-esterified Triglycerides (rTG)
​The production of a high-content DHA oil bound to TG is possible through a process called re-esterification. First, TG DHA fatty acids are esterified to Ethyl Ester (EE) and concentrated to increase the content of DHA. Then the EE molecules are broken down and re-esterified to a glycerol backbone. This enables production of concentrated forms of rTG oil. rTG is therefore a reconstituted form of the natural occurring TG.
 
Origin

Origin
For the production of this high quality algal oil a special type of micro alga has been carefully selected from nature. The strain was discovered in a mangrove forest, its natural habitat. This type of alga, named Schizochytrium Sp, is the main species that is approved for the production of DHA for human consumption. All natural origin and fish free.
