2018 ACS BOK – Domain 7: Assessment and Evaluation Bullet Points, Terms to Know and Links

ACS Body of Knowledge – Domain Seven – Cheese Assessment and Evaluation – Bullet Points, Terms to Know and Links

  • Begin your study with ACS BOK Domain Seven – Cheese Assessment and Evaluation
  • You should know how to evaluate and assess the quality of cheese using your five senses: sight, smell, taste, touch and sound.
  • Evaluation of cheese begins with the cheesemaker and Affineur and continues throughout the chain to the distributor, retailer and ending with the consumer.
  • Evaluation includes appearance, taste, smell, texture to determine condition of cheese and evaluate how the cheese will age in the following weeks.
  • Know what constitutes “bad cheese”. i.e. ammonia smell indicates that soft-ripened cheeses are over-ripe and no longer edible.
  • Understand what conditions will affect the quality and life of the cheese: quality of the milk; treatment of the milk; cleanliness of the manufacturing facility; temperature along the cold chain; packaging to protect the cheese along the supply chain; cleanliness of distributor and treatment of the cheese; cleanliness of the retail facility and treatment of the cheese.
  • What causes textures and irregularities in cheese.
  • Understand the different crystals in cheese.
  • Know flavor defects.
  • Know mechanical defects.
  • Know rind/surface defects.
  • Know odor defects.
  • Know texture defects.
  • Know origins of defects: milk composition, feed, moisture content, acid development, proteolysis, lipolysis, bacterial contamination, pathogens, yeast, mold, defects in packaging and shipping deficiencies.
  • Each family has unique characteristics. Familiarize yourself with the basic characteristics.
  • Each family has its own set of tendencies for defect. Know these.
  • Familiarize yourself with the standards of specific cheese types: http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?CFRPart=133
