Abstract


During the last decade, consumers began to pay more attention on the 100% natural, pure and Not From Concentrate (NFC) fruit juice. However, 100% natural fruit juice has shorter shelf life than the concentrated juice, due to the development of yeast and mould. Therefore, present research aimed to study the effects of propolis and black seed oil on the shelf life of freshly squeezed pomegranate juice. According to the results obtained, both propolis and black seed oil have delaying effect on the development of yeast and mould. Moreover, it was also found that combination of these treatments with freezing, increases the efficiency of tested natural treatments, as well as the shelf life.
