FFA Free Fatty Acids – what is it?
FFA, or Free Fatty Acids refer to the unbound fatty acids present in fats and oils. Unlike the fatty acids that are part of triglycerides in natural oils, free fatty acids are not attached to any other molecules. The level of FFAs in oils and fats is an indicator of the quality and freshness of the product. A higher FFA percentage often signifies degradation or spoilage, particularly in food applications, and can influence the product’s taste, odor, and shelf life.
Most common questions
1. Why is monitoring the FFA level important in the food industry?
FFA levels are directly linked to the quality of oils and fats. Elevated FFA levels can suggest that the oil or fat has undergone degradation, possibly due to factors like exposure to air, light, or heat. This degradation can negatively impact the taste, odor, and shelf life of food products. Therefore, monitoring FFA levels helps ensure product quality and consumer satisfaction.
2. How are FFA levels influenced?
Several factors can influence FFA levels. These include storage conditions, exposure to moisture, temperature fluctuations, and the presence of catalysts or contaminants. Proper storage, handling, and processing practices are essential to maintain low FFA levels in fats and oils.
3. Are FFAs present in all types of fats and oils?
While all fats and oils naturally contain some level of FFAs, the exact amount can vary depending on the source and processing method. Some oils might have inherently higher FFA levels due to their composition, while others might have elevated levels due to poor handling or storage.
4. How do FFAs impact the feed and industrial sectors?
In the feed sector, elevated FFA levels can reduce the nutritional value and palatability of the feed, affecting animal health and growth rates. In the industrial sector, high FFA levels in oils can impact their suitability for certain applications, like biodiesel production, where specific FFA thresholds need to be met.
5. How does Foodcom S.A. ensure the quality of oils and fats in terms of FFA content?
Foodcom S.A. emphasizes the importance of quality and consistency. The company sources its oils and fats from trusted suppliers, and regular quality checks are conducted to monitor FFA levels. Additionally, Foodcom S.A. offers guidance on best storage and handling practices to clients, ensuring that products retain their quality throughout the supply chain.
