Comparison of Methods for the Preparation of Fatty Acid Methyl Esters for the Analysis of Omega‐3 Rich Oils by Gas Chromatography

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Fatty acid analysis is required in a wide range of industries, and conversion to fatty acid methyl esters followed by gas chromatography is by far the most common method of analysis. However, despite widespread use, there is no consensus on which derivatization method should be used or how the methods compare.

A Direct and Practical Approach to Assessing the Impact of Emulsion Composition on Vitamin A Stability

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Vitamin A is an essential micronutrient involved in vision, immunity, and growth. Despite its widespread use in food, cosmetic, and pharmaceutical products, vitamin A is highly prone to oxidation due to its conjugated double bonds, leading to reduced biological activity and efficacy.

Methyl Substituted Long Chain 1,4‐O‐Bridged‐1,3‐Dienes—Novel Suitable Internal Standards for the GC/MS Analysis of Furan Fatty Acids in Fish Oil

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Furan fatty acids (FuFAs) are excellent antioxidants but rather unexplored because of their high instability and low contributions to the total lipids of food and biota samples. Therefore, the use of internal standards (IS) is essential for the correct determination of FuFAs in food.

Change of fatty-acid composition in plants during adaptation to hypothermia [PDF]

Journal of Stress Physiology & Biochemistry, 2010
The study of inter-species variability of fatty acid composition in leaf tissues of three species of medicinal plants growing in Predbaikal’ye showed that this composition has a species-specific character. In the composition of unsaturated fatty acids of

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

Animal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market
