 Pain Points Solved 

The "Egg Oil Pain Points" on the market mainly include unstable quality, complicated and time-consuming production processes, and consumer doubts regarding its efficacy. Consumers may face the issue of purchasing products of uneven quality or hold skepticism towards the claimed healing effects of "Egg Yolk Oil." Additionally, the cumbersome process of making egg oil at home limits product popularity and market acceptance .

The professor's exclusive process can optimize egg oil to avoid the generation of large amounts of black carbonized substances (substances causing food safety concerns) found in traditional egg oil production, and the purification efficiency is extremely high.
 

 Technology Introduction 

The use of egg oil has a long history; the "Compendium of Materia Medica" records egg oil as "Chicken Egg Oil" (Ji Zi You), and it was known as "Phoenix Oil" in ancient times. Eggs are the most nutritious and suitable for human absorption among all egg types, and egg oil is a preventive health food purely extracted from egg yolks; it is also a staple skincare product in Japanese households.

This technology uses a lower temperature simmering process throughout to completely remove the harmful substance trimethylamine produced by heating lecithin, and avoids generating excessive melanoidin substances from the Maillard reaction. Egg oil products are tracked using NMR to ensure process stability and reproducibility, achieving precise quality control.
