Increasing the comfort of healthy food has become a global trend this year. Mintel (2019) has said that a new generation of food and drink consumption has come to a close. The consumer preferences nowadays are advancing demand for more natural, nutritious, or customizable products. It can help people who have busy schedules to consume them without worrying about their health or curiosities of the ingredients, flavors or formats.
In beverage industries, they are going to produce healthy beverages, such as juice and fiber based beverages. Both have specific quality parameters, i.e.. high turbidity and cloudy visualization. It challenges the industry because of the two forms of foam on the bottom.
Formulators need to make clouding agents to stabilize the cloudy appearance in the products. The additive is the presence of emulsifying agents in water, so it wants to create a cloudy appearance in beverages.
Besides adding the clouding agents, the turbidity appearance can be done by adding essential oil, such as citrus oil. This oil is known as flavor emulsion because of its functional character as flavor enhancer and maintaining the turbidity. However, adding the clouding agents to the beverages wants to be dispersed into unstable liquids. That is because the microscopic oil droplets in the water are interacting, so they want to be separated from water.
To ensure the quality of the clouding agents based on its stability, it is necessary to use emulsion technology. Making clouding agents usually starts with a breakdown of the oil droplets into small pieces in the water phase. gum and / or modified starch, so the oil droplets will not blend. To maintain stability, the addition of other emulsifiers (co-emulsifiers) in beverages with clouding agents also needs to be done.
