In 2017， we launched the "China Good Grain and Oil" action plan, which requires that edible oil products must not only ensure "safety and hygiene", but also pay attention to "nutrition and health", and advocate the dual balance of fatty acids and nutrients. China's edible oil and processing industry has entered a new stage of "eating well" at the stage of "eating well". Edible oil no longer simply acts as the role of cooking medium and energy source, and has become an important carrier of nutritional balance.
In order to implement the "China Good Grain and Oil" action plan, LS/T 3249-2017 "China Good Grain and Oil Edible Plant Oils" was formulated in 2017. Its highlight is that it requires high requirements for nutrients in vegetable oils.
First, quantify the content of unsaturated fatty acids such as ω-3, ω-6, and ω-9 in major vegetable oils.
