“…According to the extensive review of Grappin et al (1985), R s2 -CN was considered to be totally resistant to the action of chymosin. Very recently, a study on the proteolysis of R s2 -CN by chymosin (McSweeney et al, 1994) indicated that the primary site of chymosin action appears to be Phe 88 -Tyr 89 .…”

“…Talvez este resultado seja reflexo da quebra de gordura com liberação de ácidos graxos livres, como observado por ABDEL BAKY et al [12], e estes apresentaram um poder tampão que não alterou o pH das amostras.…”

“…Na Figura 6 pode-se observar o aumento do índice de maturação com o transcorrer do período, demonstrando que houve uma proteólise das proteínas do leite, sendo que o ensaio A teve resultados semelhantes aos da literatura citada [19] e o ensaio B resultados um pouco abaixo destes valores. Durante o período de maturação ocorreu um aumento do pH dos queijos com conseqüente aumento da atividade das proteases bacterianas e proteases natural do leite [12]. Provavelmente, o ensaio A teve uma proteólise maior que o ensaio B, devido ter apresentado um pH (Figura 1) superior durante a maturação.…”

“…Possible support for the microbial arguments on proteolysis (Fox, 1981) and lipolysis may be obtained by realization that the predominant microflora in Serra cheese are lactic acid bacteria (LAB), coliforms and yeasts, especially Leuconostoc lactis, Lactoccoccus lactis ssp lactis, Lactobacillus paracasei, Hafnia alvei and Sporobolomyces roseus (Macedo et al, 1994b). AIthough LAB show, in general, considerably high proteolytic but relatively low lipolytic activities (Choisy et al, 1987), such psychrotrophic bacteria as pseudomonas and coliforms are known to secrete thermoresistant proteinases (Grappin et al, 1985) and lipases (Anon, 1991). Furthermore, P f1uo-rescens exhibits relatively high rates of production of lipases in cheese which are seriously impaired by decreasing pH (Stead, 1986), a situation which occurs during the first week of ripening in Serra cheese as a result of the action of LAB (Macedo et al, 1994a).…”
