pomace, could be a potential source for nutraceuticals development andnatural antioxidant extraction. Therefore, blueberry pomace could bedried as an antioxidant ingredient for a wide variety of food applicationsto enhance health-beneficial properties of food products.4. ConclusionsThe present work studied the effect of commercial cellulytic andpectinolytic enzymes on the selected physico-chemical and antioxidantproperties of extracted blueberry juice. In general, enzyme treatment ofthe fruit macerate before juice extraction had a positive impact on mostof the properties studied. For example, juice yield and total anthocyaninsimproved by 4.94–9.87% and 14.64–33.13%, respectively. Amongthree enzymes used, Pectinex showed the better results, especially, withhigher juice yield and higher anthocyanins extracted. Regardless of theenzymes treatment, as compared to the blueberry juice, pomace wasshown to possess a significantly higher content of total anthocyanins,total phenolics, and antioxidant activity, which was, on average, 9.84,6.40, and 3.51 folds higher, respectively. Thus, blueberry pomace couldbe dried into a shelf-stable ingredient for application in a variety of foodproducts to provided added health benefits. Blueberry juice offers ahealthy dietary choice for the consumers, and the juice processingwaste could be a potential source for natural food colorants, nutraceuticalapplications, and natural antioxidants. Further, blueberryjuice could also be processed into∼65 °Brix concentrate, which besidessignificantly increasing its shelf life, will offer expanded uses in differentfood applications.AcknowledgmentsAcknowledgment is made to the Project GREEEN at Michigan StateUniversity for partial support of this research.
