Abstract
A process for encapsulating an aroma or flavour for a beverage. An oil-in-water emulsion is formed from a hydrolyzed vegetable oil, an aqueous medium, and a water-soluble, carbohydrate-based, film forming agent. A sufficient amount of the film forming agent is added so that the aqueous phase of the emulsion contains at least 50% by weight of the film forming agent. The oil-in-water emulsion is sprayed onto a soluble beverage powder whereupon the aqueous layer of each droplet rapidly desiccates to form the capsules; the moisture content of soluble beverage powder after spraying being less than 5% by weight. In use, the soluble beverage powder is dissolved in hot water to release the aroma or flavour.
Claims21
A process for encapsulating a sensory agent, the process comprising:
- forming an oil-in-water emulsion from a hydrolyzed vegetable oil, an aqueous medium, and water-soluble, carbohydrate-based, film forming agent, the aqueous phase of the emulsion containing at least 50% by weight of the film forming agent and the emulsion containing the sensory agent, and
- spraying the oil-in-water emulsion onto soluble beverage powder;
- the moisture content of the soluble beverage powder after spraying being less than 5% by weight.
A process for encapsulating coffee aroma, the process comprising:
- forming an oil-in-water emulsion from (i) a hydrolyzed coffee oil which comprises about 60% to about 85% free fatty acids and about 40% to about 15% mono-, di- and/or triglycerides, (ii) water, and (iii) water-soluble coffee solids, the oil-in-water emulsion containing the coffee aroma and about 5 to 20% by weight of the hydrolyzed coffee oil and the aqueous phase of the oil-in-water emulsion containing about 50 to 75% by weight of the water-soluble coffee solids;
- and
- spraying the oil-in-water emulsion in droplets of size in the range of about 0.4 to about 1 mm onto soluble coffee powder;
- the moisture content of the soluble coffee powder after spraying being less than 4% by weight.
A soluble beverage powder comprising particles of soluble beverage having a moisture content of less than 5% by weight and to which are attached capsules;
- each capsule comprising an encapsulating layer of a water-soluble, carbohydrate-based, film forming agent about a core of hydrolyzed vegetable oil containing a sensory agent.
