Karamać M. author Amarowicz R. author Kostyra H. author text journal article 2002 Two pea protein isolates, Pisane and Propulse, were hydrolysed by trypsin. The degree of hydrolysis (DH) was computed using a pH-stat method. Enzymatic treatment of the pea protein isolates was conducted at four different temperatures, namely 35, 40, 45 and 50°C. The relationship between DH and E/S ratio was studied at 50°C and at four different E/S ratios; these were 5, 15, 25, 35 mAU/g (AU - Anson unit). For Pisane the highest value of the final DH (10.4%) was obtained at 45°C, whereas for Propulse the optimal temperature was 50°C and a DH value of 13.2% was attained. In the case of Pisane, the highest DH (11.5%) was recorded if the enzyme/substrate ratio was 35 mAU/g whereas for Propulse, the highest DH (13.2%) was observed at an E/S ratio of 15 mAU / g. pea; protein isolates; enzymatic hydrolysis; enzyme/substrate ratio; temperature; trypsin 10.17221/3502-CJFS https://cjfs.agriculturejournals.cz/artkey/cjf-200201-0001.php https://cjfs.agriculturejournals.cz/artkey/cjf-200201-0001.php continuing 20 1 1 6 2002 12121800 periodical academic journal
