Streszczenia
The studies concern the effect of the addition of acid whey in combination with sodium ascorbate on selected parameters related to proteolysis in uncured dry-fermented sausages. Four sausage samples (with different additives: curing mixture (C); sea salt (S); sea salt and liquid acid whey (SAW); sea salt, liquid acid whey and sodium ascorbate (SAWA)) were taken at day 0, 7, 14 and 21 of ripening to assess basic physicochemical properties, thiobarbituric acid-reactive substances (TBARS), peptides content, antioxidant properties and biogenic amines content. It was indicated that the addition the acid whey caused greater acidification of fermented sausages during processing and significantly lower level of biogenic amines and lipid oxidation. At 21 days, the pH and water activity of sausages ranged from 4.74 ± 0.01 to 5.04 ± 0.04 and from 0.868 ± 0.002 to 0.875 ± 0.003, respectively. The synergistic effect of whey and sodium ascorbate was particularly noticeable in the reduction of lipid oxidation products and antioxidant activity of peptides. The results showed a beneficial effect of the addition of acid whey in combination with sodium ascorbate on the quality features of fermented sausage.
