Summary: Avocado seed powder is a rich source of vitamins, antioxidants and minerals, which could be incorporated in cheese processing. Hence, the aim of the present work was to incorporate it in processed cheese processing where total phenolic compounds (TPC), antioxidant activity and phenolic compounds profile were determined. Moreover, chemical, physical, rheological and organoleptic characteristics of the resulted cheese were investigated. Results showed that avocado seed powder incorporation in processed cheese increased TPC (17–33 g·kg-1, expressed as gallic acid equivalents), antioxidant activity (by 32–42 %), proteins content (by 8–9 %), ash (by 5.9–6.8 %), fibre (0.2–0.3 %), fatty acids (butyric, caprylic, capric, lauric, myristic, myristoleic), minerals (Ca, Zn, Fe, Cu, Mn, P, Mg) and vitamins (A, C, E, B complex). Acidity, melting index and oil separation decreased as avocado seed powder level increased. Thus, avocado seed powder as a functional ingredient could be used in the production of novel spread-type processed cheese with good chemical, rheological and nutritional characteristics, without defects in organoleptic attributes during storage.
