Effects of Carbon Dioxide (CO ₂ ) Laser Perforation as Skin Pretreatment to Improve Sugar Infusion Process of Frozen Blueberries

Abstract

CO(2) laser perforation as a novel skin pretreatment for sugar infusion of individually quick frozen (IQF) blueberries is presented. The technique markedly improves the product yield and quality. Although further investigation is needed, the method may potentially be used for other waxy skin fruits such as cranberries and cherries.
