The team of Professor Chongjiang Cao of China Pharmaceutical University constructed a multifunctional composite fresh-keeping material and verified its effectiveness in the preservation of harvested vegetables.

Recently, Professor Cao Chongjiang from the School of Engineering of China Pharmaceutical University and the National Research and Development Center of Chinese Medicinal Materials Processing Technology has made progress in the multi-functional preservation of harvested vegetables.

Key points

The natural water-locking factor, ceramide is encapsulated in the pre-synthesized mesoporous HKUST-1 (Cer@MHKUST-1);

Cer@MHKUST-1 has multiple functions such as adsorption of ethylene, water lock, antibacterial, etc.

Cer@MHKUST-1 composite packaging can effectively slow down food decay;

Cer@MHKUST-1 composite packaging has broad application prospects in the field of post-harvest food preservation

Background introduction:

According to incomplete statistics, hunger and chronic malnutrition affect more than 800 million people around the world.

Metal-Organic Frameworks (MOFs) are a type of porous crystalline material composed of inorganic nodes (metal ions/clusters) and organic ligands through self-assembly.

In addition, the water loss of harvested vegetables can interfere with their normal physiological metabolism, damage cell tissues, reduce enzyme activity, and cause product quality to decline

In this project, HKUST-1 was selected as the carrier.
