Researchers at Purdue University have developed natural, plant-based, functional, and sustainable wall materials from sweet corn for spray-dry microencapsulation of foods. In the food industry, core materials are embedded in wall materials for prolonged protection and convenient use. None of the wall materials currently used by the industry meet all the criteria of: "natural, plant-based, functional, and sustainable." Not only satisfying these qualities, the wall materials developed by the Purdue researchers are also amphiphilic; they are both hydrophilic and lipophilic, allowing compatibility with a wide range of ingredients. Additionally, the materials are cost-effective.

Technology Validation: The researchers generated sweet corn extracts to prepare spray-dry microencapsulation solids for blueberry syrup, beet juice, paprika oleoresin, orange oil, and lutein oil. For paprika oleoresin, the sweet corn extracts were stronger emulsifiers and more resistant to light and heat treatments than OSA-starch, which is the industry-standard wall material.
