DTRI soft cheese or “kesong puti” is a fresh, unripened soft cheese prepared by concentrating the protein, fat, some vitamins and minerals of milk, usually through enzymatic milk coagulation and natural draining of the resulting curd.
On a per weight basis, soft cheese or DTRI “Kesong Puti” contains 5 times more protein and milk fat than fresh milk.
- 2 liters fresh milk (carabao, cow or goat’s)
- 2 tbsp DTRI coagulant/rennet extract*
- 2-3 tbsp heaping table salt
*Rennet is an extract prepared from a mixture of abomasum, glacial acetic acid, and salt. DTRI coagulant and rennet are available at the Dairy Training Research Institute at UP Los Banos, Laguna.
- kettle (casserole)
- perforated plastic tray
- cheesecloth (“katsa”)
- cheese wrappers (wax paper or banana leaves)
- kitchen thermometer (optional)
- 8 pieces cheese moulds (ex: open-end milk can)
- Carabao’s milk – about 6 blocks (approx. weight of 200 g each)
- Cow’s or goat’s milk – about 4 blocks (approx. weight of 200 g each)
- Dissolve the table salt into the milk.
- Filter the salted milk into a clean kettle.
- Heat the milk to about 72° C for 1-2 minutes (at this temperature, vapor or steam is seem rising from the surface).
- Immediately place the kettle of milk i a basin of cold or tap water and stir the milk until lukewarm (about 40 to 42° C).
- Add the coagulant and stir for one minute. Cover and leave the milk undisturbed for 20-25 minutes. After this period, the milk should be coagulated (custard-like or has a texture similar to “taho”).
- Cut the coagulated milk or coagulum across with the distance of one inch between cuts. Leave the cut coagulum undisturbed for 5-10 minutes.
- Arrange cheese mould in a perforated plastic tray lined with cheesecloth. The tray should rest on a basin.
- For carabao’s milk, scoop the cut coagulum (2-3 cm thick) into the cheese moulds.
- For cow’s or goat’s milk, [a] stir the coagulum slowly for 10-15 minutes (avoid shattering the coagulum into fine pieces). [b] Remove about a liter of the liquid (whey). [c] Pour or scoop the partly drained curd into the cheese moulds. The thickess of the coagulum inside the mould should be about 2.5-3.0 inches.
- Cover the moulds and drain the cheese for 3-5 hours at room temperature or 6-8 hours at refrigerated temperature.
- After the draining period, lift the moulds leaving the cheese behind then wrap each cheese cake with waxed paper or banana leaves.
- Soft or white cheese will remain acceptable within 2 days at room temperature and 5-7 days when stored in a refrigerator.
- Shelf-life of soft cheese or white cheese is longer if the amount of salt is doubled.
- The flavor and texture of the cheese are enhanced or improved 24 hours after its manufacture.
- If cheese becomes moldy within the predicted shelf-life period, do not discard, wash the surface of the cheese with water and it will still be acceptable.
