| Animal Feed | Additive | Added to animal feed to enhance nutritional value and promote animal growth and development |
Manufacturing Quality Control of Linoleic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | The sample is derivatized into fatty acid methyl esters (FAME), then separated and quantified for linoleic acid content using gas chromatography, offering high resolution and accuracy. |
| High-Performance Liquid Chromatography (HPLC) | Suitable for non-volatile or thermally unstable fatty acids; can be coupled with UV or mass spectrometry detectors for qualitative and quantitative analysis. | |
| Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the structural identification power of MS, enabling accurate identification and quantification of linoleic acid, especially in complex matrices. | |
| Purity Analysis | Nuclear Magnetic Resonance Spectroscopy (NMR) | Uses ¹³C or ¹H NMR to analyze the molecular structure of linoleic acid, assessing purity and detecting impurities or isomers. |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Based on the characteristic absorption of conjugated double bonds near 234 nm, useful for preliminary assessment of oxidation level or conjugated linoleic acid content. | |
| Fatty Acid Composition Analysis | Gas Chromatography (GC) | Widely used for simultaneous analysis of multiple fatty acids in animal/plant oils or formulations; identifies and quantifies the proportion of linoleic acid by comparing retention times with standards. |
| Peroxide Value | Iodometric Method | Measures peroxide content in oils, indirectly reflecting the initial oxidation degree of unsaturated fatty acids such as linoleic acid. |
| Acid Value/Acidity | Acid-Base Titration | Titrates free fatty acids with a standard alkaline solution to evaluate the amount of newly formed free acids (including linoleic acid), indicating the extent of hydrolysis. |
| Iodine Value | Wijs Method | Determines the degree of unsaturation in oils; higher iodine values indicate higher levels of unsaturated fatty acids such as linoleic acid. |
| Isomer Detection | Reversed-Phase HPLC (RP-HPLC) or Silver Ion Chromatography (Ag⁺-HPLC) | Separates cis/trans isomers or positional isomers of double bonds, used to detect trans-linoleic acid potentially formed during hydrogenation. |
