RENNET

Rennet is an enzyme which acts on protein and causes it to coagulate. There are two sources of rennet enzyme. Animal rennet is an enzyme which is extracted from the fourth stomach of calves and vegetable based rennet.

Vegetable based rennet contains no animal products and has the same coagulating ability as animal rennet when used in milk that has been ripened (acidified) by a cheese starter bacteria. This rennet is available in tablet and liquid form. Rennet must be diluted with distilled water prior to adding to milk. Rennet must be refrigerated.



Rennet 這種東西，似乎有分素食與葷的。可惜我英文不好，可否有村民大德願意寫信給該網站人員，問清楚Rennet 是不是一定就是葷的呢？
