It’s always great to hear from Curd-Nerds who’ve tried the methods we write about and have had success! In some cases, these released molecules can positively contribute to flavor but also negatively via off-flavor production, such as bitterness, if not properly monitored and controlled. Both mold- and bacterial-ripened cheeses are then ripened at 10–15 °C to promote microbial growth and activity, and at a high relative humidity to prevent loss of moisture from the cheese surface. Protease enzymes, in general, are known to extensively degrade milk caseins thereby participating in deacidification, textural cheese modifications, and aroma production as some precursor compounds are liberated (peptides and amino acids) (Sousa et al., 2001; Ardö, 2011). A. Abbas, A.D.W.
