Proteolysis of prato type cheese produced using ultrafiltration

Abstract: The application of milk ultrafiltration technology for cheese manufacture presents several advantages. However, it also influences proteolysis and, consequently, cheese ripening. The effects of five different processing methods for Prato cheese were evaluated with respect to the time evolution of the extent and depth of proteolysis indexes (EPI and DPI). The following treatments (T) for cheese production were studied: T1 -without ultrafiltration (standard); T2, T3, T4 and T5 -using milk concentrated by ultrafi… Show more

“…To evaluate proteolysis in the cheeses, the protein fractions were determined by the Kjeldahl method, evaluating the contents of total nitrogen (TN) (%), noncasein nitrogen (NCN) (%) and nonprotein nitrogen (NPN) (%) (Bynum and Barbano 1985;AOAC 2005). The primary proteolysis index was determined from the NCN/TN ratio, and the secondary from the NPN/TN ratio (Spadoti et al 2005;Vianna et al 2010;Gasparini et al 2020).…”

“…Los valores para los índices de maduración (ARE y RD) en el queso tradicional son similares a los encontrados por Spadoti et al (2005) al seguir la maduración de queso Prato. Estos investigadores obtuvieron, a los 25 días de maduración, valores del índice ARE del 15-20 % y del 6-8 % para el índice RD, similares a su vez a los recogidos por Van der Berg et al (1993) en su revisión tecnológica del proceso de maduración, trabajando con queso Gouda.…”

“…Η αύξηση του συντελεστή ωρίµανσης έχει αναφερθεί σε πολλές εργασίες (Kebary et al, 1997b;Agboola and Radovanovic-Tesic, 2002;Gobbetti et al, 2002;Öner et al, 2006;Tarakci and Kucukoner, 2006). Έχει βρεθεί επίσης ότι οι χαµηλότερες τιµές pH αυξάνουν τη δραστικότητα της χυµοσίνης η οποία είναι ένζυµο, υπεύθυνο για την πρωτεόλυση, µε αποτέλεσµα την παράλληλη αύξηση του συντελεστή ωρίµανσης (Spadoti et al, 2005).…”
