Methods for the application of ingredients to the inside of a straw

Abstract

Methods of coating the interior surface of a hollow tubular structure, in particular a drinking device, and more particularly a drinking straw, with an edible composition to impart a desirable modification to a beverage that is drunk through the straw. The edible composition comprises an adhering agent and a powdered ingredient coated to the interior surface. Suitable adhering agents include lipids (e.g., soybean oil, corn oil, canola oil, sunflower oil, rapeseed oil, peanut oil, and mixtures thereof), medium chain triglycerides oils, emulsifiers, and mixtures thereof. Suitable powdered ingredients include edible acids, edible bases, sweeteners, flavorings, vitamins, minerals, colorants, sensate agents, carotenoids, antioxidants, polyphenols, phytonutrients, and mixtures thereof. The adhering agent is applied to the interior surface of the straw by any one of a number of methods followed by incorporating the powdered ingredient into the adhering agent layer. The powdered ingredient adheres or sticks to, and is incorporated into, the adhering agent layer. Once the powdered ingredient layer is added, the coated drinking straw is ready for use with a beverage.
