Fresh date processing (picking, storage or conditioning) may lead to date losses. Such by-products from fresh dates (Medjoul variety) can be processed to prepare date paste. Chemical composition, physicochemical and technological properties of this date paste were determined regarding its potential application as an ingredient in the elaboration of meat products. The date paste had a high content of sugars (53.00g/100g) especially reducing sugars (fructose and glucose), total and insoluble dietary fiber (7.00g/100g and 4.04g/100g, respectively) and natural antioxidants (polyphenol content; 225mg GAE/100g). Its emulsion capacity was 57.00mL/100mL and it showed also a high emulsion stability (98.59mL/100mL). The addition of up to 15% date paste in the formulation of bologna-type products leads to the enhancement of the nutritional (lower fat content and higher fiber content than control) and technological quality (redder-colored and less hard, chewy and cohesive product than the control) together with a satisfactory sensory quality.
