Oil body treated by cross-linking agent with increased stability

The present invention relates to an oil body treated by a cross-linking agent with increased stability. The oil can be an artificial oil body recombined using the major ingredients of natural oil body, triglyceride, phospholipids, and oil body proteins, or a natural oil body. The cross-linking agent can be genipin, reuterin or called 3-hydroxypropinoaldehyde, or glutaraldehyde. The oil body with increased stability according to the present invention has a wider range of applications. In particular, the use of a natural cross-linking agent with extremely low toxicity, such as genipin and reuterin, further enables the oil body to be used in the fields of food industry, drug delivery, and biomedical materials.
