In this invention, the purpose is to provide a shelf-stable spray-dried powder embodying a desired organic oil, such as a flavorant, for example. First, hydroxylated lecithin is subject to a high-energy power input, such as by vigorous stirring or microfluidization or sonication. To make a uniform mix, the resultant product is mixed with a poloxamer surfactant, water, and the desired organic oil, whether it be a flavoring, insect repellent, paint base or other organic oil. This is then subjected to energization input again, such as by microfluidization or sonication. Following this, bulking agents are added and the mixture is spray-dried. This invention shows the novel improvement of spray-dried material of the oil, lecithin, and surfactant to produce an extended shelf-life with little escape of organic oil ingredient.
