The advantages of using sublimation for preserving the antioxidant properties of cranberries

Abstract

Abstract The benefits of using the sublimation method for preserving the antioxidant properties of cranberries have been studied. Cranberries are known for their antioxidant properties, which help combat infections, reduce the risk of heart disease, and improve arterial pressure. This berry is particularly beneficial in prostate cancer. Most of the beneficial compounds in cranberries are found in their skin, which may lose its properties during traditional juice extraction. Drying is an alternative method for preserving antioxidants, but traditional methods can lead to a loss of product quality. Sublimation drying has proven to be the most efficient and innovative method, as it ensures the preservation of cranberry antioxidant properties. After the sublimation cycle, the final moisture content of the material is only 2–5 % of the initial content, guaranteeing the maximum retention of beneficial properties and the production of a high-quality product. This method is promising for maintaining the quality of raw materials during drying and preserving their medicinal properties.
