A recently granted patent (Publication Number: US11864577B2) outlines a method for producing microencapsulated oil-and-fat, involving the microencapsulation of the oil-and-fat in an embedding wall material. The process includes subjecting both the oil-and-fat and the embedding wall material to carbon dioxide treatment, which entails introducing carbon dioxide, refrigerating the materials for 1-8 hours, and subsequently removing the carbon dioxide. The carbon dioxide treatment is conducted with specific parameters, such as introducing 1000-5000 ppm of carbon dioxide and refrigerating at a temperature of 1-5°C for 4-6 hours.
Furthermore, the method involves various steps in the microencapsulation process, including compounding, refining, emulsifying, homogenizing, and spray drying. The oil-and-fat used can be sourced from vegetable oils like soybean oil, rapeseed oil, corn oil, and sunflower oil, as well as animal oil-and-fats such as fish oil, whale oil, lard, mutton tallow, beef tallow, and cream. The microencapsulated oil-and-fat composition comprises a dry matter with specific mass percentages of oil-and-fat and embedding wall material. Additionally, the dry matter may contain emulsifiers, antioxidants, and anti-caking agents in specified mass percentages, with options like phospholipids, vitamin C, tricalcium phosphate, and more. The carbon dioxide treatment can be fine-tuned with different parameters, such as introducing 1000 to 3000 ppm of carbon dioxide and refrigerating at 1-5°C for 4-6 hours, showcasing the versatility and precision of the method.
