Fats are commonly found in both animal-based and plant-based foods. They are formed by esterifying one glycerol molecule with three fatty acid molecules. The specific composition, properties, and functions of fats in foods are primarily determined by their constituent fatty acids. Over 40 types of fatty acids exist in nature, leading to significant variations in fat characteristics across different food sources.
Fats Category | Source | Primary Fats |
---|---|---|
Animal-derived Fats | dairy | short-chain fatty acids and cholesterol |
meat | saturated fatty acids | |
fish | ω-3 polyunsaturated fatty acids | |
Plant-derived Fats | oilseed | unsaturated fatty acids |
nut | vitamin E and polyunsaturated fatty acids | |
coconut oil and palm oil | saturated fatty acids | |
Fats in Processed Foods | hydrogenated vegetable oils | trans fatty acids |
fried and baked foods | oxidized fats |
Aprofood provides customized testing solutions for different food matrices, analyzing the full range of lipid components, including total fat, saturated fat, polyunsaturated fat, monounsaturated fat, and trans fat. Our service portfolio includes the following key testing items:
We mainly measure the total amount of all lipids, including triglycerides, phospholipids, sterols, etc. We can also accurately measure the solid fat content of fat-based foods such as chocolate, butter, cream, ice cream, etc., using differential scanning calorimetry (DSC).
Through systematic detection using GC-MS and LC-MS methodologies, we precisely determine the quantitative composition of saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and trans fatty acids in food products.
We conduct a comprehensive analysis of beta-glucan, including beta-glucan total content determination, molecular weight distribution analysis, solubility analysis, and structure-function characterization. The analytical techniques we employ include High-Performance Liquid Chromatography (HPLC), High-Performance Gel Permeation Chromatography (HPGPC), and Scanning Electron Microscopy (SEM).
