Lipids testing
Introduction
Lipids, often referred to as fats, are a diverse group of organic compounds crucial for both human health and food quality. Understanding their types and testing methods is essential for maintaining a healthy diet and ensuring food safety and quality.
Importance of Lipid Testing in Food
Assessing nutritional value: Measuring total fat content, saturated and unsaturated fat ratios, and essential fatty acids like omega-3 and omega-6.
Ensuring food safety: Detecting rancidity (oxidation) that affects taste and can be harmful.
Quality control: Maintaining consistent texture, shelf life, and flavor in processed foods.
Preventing health risks: Monitoring levels of harmful saturated and trans fats associated with cardiovascular disease.
Lipids are an important component of many food items, and analysing their composition serves various functions:

Lipids market overview
In 2022, the global lipid market reached a valuation of USD 13.63 billion, with a projected compound annual growth rate (CAGR) of 6.9% from 2023 to 2030. This growth is primarily driven by the expanding applications of lipids in various industries, including pharmaceuticals, food & beverages, and nutrition supplements. The surge in demand for lipids, fueled by their crucial role in developing COVID-19 vaccines, is expected to further propel market expansion. Lipids, valued for their high energy and fat-soluble vitamin contents, are recognized as vital ingredients in the formulation of dietary supplements. The heightened awareness of health issues, particularly amidst the COVID-19 pandemic, has led to an increased global demand for dietary supplements. This trend is contributing significantly to the growth of the lipid market.
