Free fatty acid content
The level of free fatty acids indicates the degree of hydrolysis and can affect the oil's flavor and stability.
Peroxide value
Peroxide value measures the initial products of oxidation, which can lead to rancidity and off-flavors.
Color
The color of the oil can indicate the degree of refining and the presence of impurities, affecting its suitability for certain applications.
Flavor and odor
The presence of off-flavors or odors, such as fishy or paint-like notes, can indicate oxidation or contamination.

Common Defects

Recorded defects for flaxseed oil include Rancidity, Cloudiness or sediment, and High free fatty acid content.

Rancidity
Oxidation leads to the development of off-flavors and odors, often described as fishy or paint-like, indicating the oil is rancid.
Cloudiness or sediment
Exposure to light or heat can cause the oil to become cloudy or develop sediment, affecting its appearance and quality.
High free fatty acid content
The presence of free fatty acids indicates hydrolytic rancidity, which can result from poor handling or storage conditions.
