Grain and edible oil
The country is based on the people, and food is the most important thing for the people. Food is based on food, and food safety comes first. Grain is an important food raw material and strategic material, and the quality and safety of food are directly related to the physical health and life safety of the people. However, in recent years, with the acceleration of industrialization and urbanization in China, environmental pollution has become increasingly severe, and the increase of Jiduan climate, hidden dangers of food quality and safety have become increasingly prominent. In China's food quality inspection reports, common food problems include pesticide pollution, fungal toxin pollution, heavy metal pollution, and other problems.
The quality and safety issues of edible oil mainly come from various stages of oil crop cultivation, harvesting, storage, processing, and use. Including huangqumei toxins introduced during planting and storage processes; Oil undergoes oxidation and rancidity, leading to an increase in acid value and peroxide value. Various low-quality problem oils that exist in daily life, such as repeatedly used frying oils.

Rapid detection technology for pesticide residues

Developed * pesticide rapid testing card, accumulated and innovated continuously for more than 20 years, has won multiple inventions, and related technological achievements have won awards such as the second prize of National Science and Technology Progress Award and the second prize of China Shennong Science and Technology Award. The product is fast, stable, and convenient; It can be widely used for rapid detection of pesticide residues such as organophosphorus, carbamate, pyrethroid, organochlorine, and neonicotinoid in edible agricultural products such as vegetables, fruits, grains, tea, mulberry leaves, and tobacco leaves.

Rapid detection technology for heavy metals
Guangdong Dayuan Oasis Food Safety Technology Co., Ltd., in cooperation with Sun Yat sen University, Guangdong Provincial Center for Disease Control and Prevention, and other units, has jointly broken through key technologies and solved the problems of complex maintenance, interference, and accuracy of traditional electrochemical detection instrument sensors. It is easy to operate, highly sensitive, and portable, suitable for rapid quantitative detection of heavy metal pollutants such as lead and cadmium in grain.

Rapid detection technology for fungal toxins
By combining chromatographic chromatography technology, polymer nanomaterials technology, and immunological principles technology, multiple rapid detection reagents and instruments have been developed, which have the characteristics of high detection accuracy, strong stability, and fast detection speed. They are suitable for rapid qualitative or quantitative detection of fungal toxins such as huangqumei toxin B1 and zearalenone in grains and edible oils.
