Inevitably, the freezing process and the frozen storage have negative impacts on food quality. The main physical changes that occur during frozen storage are moisture migration and ice recrystallization (Van Buggenhout et al., 2006). Both phenomena are related to the stability of products (frozen water) which affects the vegetable texture and loss of nutrients and weight if thawing drip loss takes place (Pukszta and Palich, 2007). Moreover, chemical changes in frozen vegetables are related with onset of off-odor and off-flavors (especially if vegetables were not blanched) Nielsen et al., 2003), pigment and color degradation (Lisiewska et al., 2004) and chemical oxidation e.g. of vitamin C
