The free fatty acid (FFA) content of the VCO was measured according to the standard Association of Official Agricultural Chemists (AOAC) method (Horwitz, 2000). About 7.05 g of each VCO sample was mixed with 2 ml phenolphthalein solution and a few drops of 0.1 M NaOH; 50 ml of ethanol was then added to the solution and vigorously shaken until a ...

2015年12月9日 · The quality of virgin coconut oil (VCO), together with its health functionalities, is directly related to its freshness and to the levels of free fatty acids (FFA). Acid-base titration is the reference method for the determination of FFA in oils.

2023年6月1日 · The fatty acid profile of the VCO is highly important due to its functional and nutritional properties and the proportion of the Fatty acids varied significantly, while the highest lauric acid content resulted in VCO of CRISL 2013 (hybrid-based) and …

Free fatty acids (FFA) is a value that indicates the amount of free fatty acids present in fat after the fat is hydrolyzed. Free fatty acids are the result of degradation of triglycerides as a result of oil damage. The results of the test for free fatty acids are presented in Table 1. The FFA value of the VCO produced was very low, only 0.08%,

2020年11月1日 · Of all the samples, VCO showed 1.3% FFA which was higher when compared, that it should be consumed only to a certain limit for cooking. VCO has very low moisture content of 0.11% where the...

2022年1月29日 · One parameter of quality control for oil is free fatty acids (FFA) and acid number. The number of FFA might be increased because of several factors; therefore it delivered bad quality of VCO. One technique to reduce FFA and AN is using activated carbon to adsorb oils. Adsorption is a technical operation widely used in industrial applications.

VCO was meet the standards for specific gravity (0.9149), refractive index (1.4546) and water content (0%). The fatty acid component was tested using GCMS with the highest concentration, was ...

Download scientific diagram | Profil of %FFA content in VCO. from publication: The effect of active carbon adsorbents from some wastes in reducing free fatty acids and acid number to improve...

2008年7月23日 · Total sterols were higher in VCO (0.096%) compared with RCO (0.032%), and the FFA content was 8 times higher in VCO than RCO (0.127% vs 0.015%). FFA determination by (31)P NMR and titration gave comparable results. Principal components analysis shows that the 1,2-DG, 1,3-DG, and FFAs are the most important parameters for differentiating VCO ...

Of all the samples, VCO showed 1.3% FFA which was higher when compared, that it should be consumed only to a certain limit for cooking. VCO has very low moisture content of 0.11% where the shelf life of oil can be naturally preserved.
