Long-keep cream without preservatives

A method for producing oil-in-water emulsions having an average particle size of less than 3 μm, comprising the following steps:

• (a) subjecting an oil-in-water emulsion to a first high-pressure homogenization at a temperature in the range from about 50° C. to about 100° C.,
• (b) heating the product obtained in step a) to about 135° C. up to about 150° C.,
• (c) cooling the product obtained in step b) to a temperature below 100° C.,
• (d) subjecting the product obtained in step c) to a second high-pressure homogenization at a temperature in the range from about 50° C. to about 80° C. and a pressure in the range from about 60 to about 100 bar,
• (e) cooling the product obtained in step d) to a temperature from about 0° C. to about 10° C., wherein the cooling temperature is reached in a time interval from 1 to 10 seconds, and
• (f) packaging the product obtained in step e).
