This may give you more of an idea of the three different lipases used by cheesemakers. It is an edit from this webpage, http://www.au-kbc.org/beta/bioproj2/uses.html
The traditional sources of lipases for cheese flavour enhancement are animal tissues, especially the pre-gastric tissues (tongue roots) of young ruminants(kid,lamb,calf). The latter are more commonly used in cheese making. The commercial pre-gastric lipases are available in the form of liquid extracts, pastes and vacuum or freeze dried powders. Each type of pre-gastric lipase gives rise to its own charecteristic flavour profile : a buttery and slightly peppery flavour(calf) ; a sharp ‘piccante’ flavour (kid); a strong ‘pecerino’ also described as ‘dirty sock’ flavour(lamb).
Here is the text of an email sent to me by Melvyn Smith,the representative of Renco, New Zealands leading mfr of cheesemaking enzymes. The suggestions refer to their product strength of 80 LFU/gram
Dear Kev & Susie,
Thank you for your query. How you use the PGE (lipase) is very much determined by individual taste, the type of cheese and the maturation time for the cheese. Some experimentation will be required. My starting suggestions below.
Use by adding to the milk at the time of starter addition:
3.5g/10L for a strong response
0.5g/10L for a mild response
I hope this is sufficient to get you started and I trust you will enjoy the result.
Regards,
Melvyn
(I have been using a level teaspoon of the dry powder per 20 litres as a starting point).
Hope my first post is of some use to you, I look forward to being part of this forum.
