Defects - General, Body
This webpage is divided into the following topics:
Cracks
Description
- Body, interior of cheese has unwanted cracks.
Causes
- Temperature during aging was too high which caused expansion of
air in internal cracks to expand resulting in cracks in cheese.
Dry
Description
- Texture of cheese is too dry and thus hard.
Causes
- Too much rennet used resulting in excessive whey expelled from curds.
- Curds cut into too small pieces resulting in excessive whey
expelled from curds.
- Cur curds stirred excessively or for too long or at too high a
temperature resulting in excessive whey removed form curds.
- Cheese too acidic, ripen for less time or add less starter
culture.
- If natural rind, ripening/aging environment's humidity is too low.
Holes
Description
- Body of cheese has unwanted holes or eyes.
Causes
- Yeast contamination of the curds resulting in production of
carbon dioxide gas within the cheese.
Moist
Description
- Texture of cheese is too moist and thus soft.
Causes
- Too little rennet used and thus too much whey retained in the curds.
- Curds cut into too large pieces.
- Cut curds stirred too little or for too short a time or for too low a
temperature resulting in too much whey retained in the curds.
- Cut curds warmed too rapidly initially causing rapid expulsion of whey
from surface of cut curds which results in a dehydrated layer inhibiting
further expulsion of whey from interior of cut curds.
- Acidity level is too high, ripen longer or use more starter.
- Inadequate pressing (weight and time) for hard cheeses.
- If natural rind, aging environment's humidity is too high.
Plasticity
Description
- Cheese will not stretch, has low plasticity in Pasta Filata (pulled) type cheeses.
Causes
- Acidity level was not within 5.0-5.2 range. Check pH, if too low (greater than 5.2), ripen the curd longer, if too high (lower than 5.0) then shorten the ripening time of the curd.
Rubbery
Description
- Texture of finished cheese is too rubbery.
Causes
- Using too much rennet.
- Overheating during making stage.
- If washed curd cheese, remove less whey or replace removed whey with less fresh water.
